How can I get started with Intel XDK?
There are plenty of videos and articles that you can go through here to get started. You could also start with some of our demo apps. It may also help to read Five Useful Tips on Getting Started Building Cordova Mobile Apps with the Intel XDK, which will help you understand some of the differences between developing for a traditional server-based environment and developing for the Intel XDK hybrid Cordova app environment.
Having prior understanding of how to program using HTML, CSS and JavaScript* is crucial to using the Intel XDK. The Intel XDK is primarily a tool for visualizing, debugging and building an app package for distribution.
You can do the following to access our demo apps:
- Select Project tab
- Select "Start a New Project"
- Select "Samples and Demos"
- Create a new project from a demo
If you have specific questions following that, please post it to our forums.
Can I use an external editor for development in Intel® XDK?
Yes, you can open your files and edit them in your favorite editor. However, note that you must use Brackets* to use the "Live Layout Editing" feature. Also, if you are using App Designer (the UI layout tool in Intel XDK) it will make many automatic changes to your index.html file, so it is best not to edit that file externally at the same time you have App Designer open.
Some popular editors among our users include:
- Sublime Text* (Refer to this article for information on the Intel XDK plugin for Sublime Text*)
- Notepad++* for a lighweight editor
- Jetbrains* editors (Webstorm*)
- Vim* the editor
How do I get code refactoring capability in Brackets* (the Intel XDK code editor)?

What is the global-settings.xdk file and how do I locate it?
global-settings.xdk contains information about all your projects in the Intel XDK, along with many of the settings related to panels under each tab (Emulate, Debug etc). For example, you can set the emulator to auto-refresh or no-auto-refresh. Modify this file at your own risk and always keep a backup of the original!
You can locate global-settings.xdk here:
- Mac OS X*
~/Library/Application Support/XDK/global-settings.xdk - Microsoft Windows*
%LocalAppData%\XDK - Linux*
~/.config/XDK/global-settings.xdk
If you are having trouble locating this file, you can search for it on your system using something like the following:
- Windows:
> cd /> dir /s global-settings.xdk - Mac and Linux:
$ sudo find / -name global-settings.xdk
When do I use the intelxdk.js, xhr.js and cordova.js libraries?
The intelxdk.js and xhr.js libraries were only required for use with the Intel XDK legacy build tiles (which have been retired). The cordova.js library is needed for all Cordova builds. When building with the Cordova tiles, any references to intelxdk.js and xhr.js libraries in your index.html file are ignored.
How do I get my Android (and Crosswalk) keystore file?
New with release 3088 of the Intel XDK, you may now download your build certificates (aka keystore) using the new certificate manager that is built into the Intel XDK. Please read the initial paragraphs of Managing Certificates for your Intel XDK Account and the section titled "Convert a Legacy Android Certificate" in that document, for details regarding how to do this.
It may also help to review this short, quick overview video (there is no audio) that shows how you convert your existing "legacy" certificates to the "new" format that allows you to directly manage your certificates using the certificate management tool that is built into the Intel XDK. This conversion process is done only once.
If the above fails, please send an email to html5tools@intel.com requesting help. It is important that you send that email from the email address associated with your Intel XDK account.
How do I rename my project that is a duplicate of an existing project?
See this FAQ: How do I make a copy of an existing Intel XDK project?
How do I recover when the Intel XDK hangs or won't start?
- If you are running Intel XDK on Windows* it must be Windows* 7 or higher. It will not run reliably on earlier versions.
- Delete the "project-name.xdk" file from the project directory that Intel XDK is trying to open when it starts (it will try to open the project that was open during your last session), then try starting Intel XDK. You will have to "import" your project into Intel XDK again. Importing merely creates the "project-name.xdk" file in your project directory and adds that project to the "global-settings.xdk" file.
- Rename the project directory Intel XDK is trying to open when it starts. Create a new project based on one of the demo apps. Test Intel XDK using that demo app. If everything works, restart Intel XDK and try it again. If it still works, rename your problem project folder back to its original name and open Intel XDK again (it should now open the sample project you previously opened). You may have to re-select your problem project (Intel XDK should have forgotten that project during the previous session).
- Clear Intel XDK's program cache directories and files.
On a Windows machine this can be done using the following on a standard command prompt (administrator is not required):> cd %AppData%\..\Local\XDK> del *.* /s/q
To locate the "XDK cache" directory on [OS X*] and [Linux*] systems, do the following:$ sudo find / -name global-settings.xdk$ cd <dir found above>$ sudo rm -rf *
You might want to save a copy of the "global-settings.xdk" file before you delete that cache directory and copy it back before you restart Intel XDK. Doing so will save you the effort of rebuilding your list of projects. Please refer to this question for information on how to locate the global-settings.xdk file.
- If you save the "global-settings.xdk" file and restored it in the step above and you're still having hang troubles, try deleting the directories and files above, along with the "global-settings.xdk" file and try it again.
- Do not store your project directories on a network share (Intel XDK currently has issues with network shares that have not yet been resolved). This includes folders shared between a Virtual machine (VM) guest and its host machine (for example, if you are running Windows* in a VM running on a Mac* host). This network share issue is a known issue with a fix request in place.
- There have also been issues with running behind a corporate network proxy or firewall. To check them try running Intel XDK from your home network where, presumably, you have a simple NAT router and no proxy or firewall. If things work correctly there then your corporate firewall or proxy may be the source of the problem.
- Issues with Intel XDK account logins can also cause Intel XDK to hang. To confirm that your login is working correctly, go to the Intel XDK App Center and confirm that you can login with your Intel XDK account. While you are there you might also try deleting the offending project(s) from the App Center.
If you can reliably reproduce the problem, please send us a copy of the "xdk.log" file that is stored in the same directory as the "global-settings.xdk" file to html5tools@intel.com.
Is Intel XDK an open source project? How can I contribute to the Intel XDK community?
No, It is not an open source project. However, it utilizes many open source components that are then assembled into Intel XDK. While you cannot contribute directly to the Intel XDK integration effort, you can contribute to the many open source components that make up Intel XDK.
The following open source components are the major elements that are being used by Intel XDK:
- Node-Webkit
- Chromium
- Ripple* emulator
- Brackets* editor
- Weinre* remote debugger
- Crosswalk*
- Cordova*
- App Framework*
How do I configure Intel XDK to use 9 patch png for Android* apps splash screen?
Intel XDK does support the use of 9 patch png for Android* apps splash screen. You can read up more at https://software.intel.com/en-us/xdk/articles/android-splash-screens-using-nine-patch-png on how to create a 9 patch png image and link to an Intel XDK sample using 9 patch png images.
How do I stop AVG from popping up the "General Behavioral Detection" window when Intel XDK is launched?
You can try adding nw.exe as the app that needs an exception in AVG.
What do I specify for "App ID" in Intel XDK under Build Settings?
Your app ID uniquely identifies your app. For example, it can be used to identify your app within Apple’s application services allowing you to use things like in-app purchasing and push notifications.
Here are some useful articles on how to create an App ID:
Is it possible to modify the Android Manifest or iOS plist file with the Intel XDK?
You cannot modify the AndroidManifest.xml file directly with our build system, as it only exists in the cloud. However, you may do so by creating a dummy plugin that only contains a plugin.xml file containing directives that can be used to add lines to the AndroidManifest.xml file during the build process. In essence, you add lines to the AndroidManifest.xml file via a local plugin.xml file. Here is an example of a plugin that does just that:
<?xml version="1.0" encoding="UTF-8"?><plugin xmlns="http://apache.org/cordova/ns/plugins/1.0" id="my-custom-intents-plugin" version="1.0.0"><name>My Custom Intents Plugin</name><description>Add Intents to the AndroidManifest.xml</description><license>MIT</license><engines><engine name="cordova" version=">=3.0.0" /></engines><!-- android --><platform name="android"><config-file target="AndroidManifest.xml" parent="/manifest/application"><activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:launchMode="singleTop" android:name="testa" android:theme="@android:style/Theme.Black.NoTitleBar"><intent-filter><action android:name="android.intent.action.SEND" /><category android:name="android.intent.category.DEFAULT" /><data android:mimeType="*/*" /></intent-filter></activity></config-file></platform></plugin>
You can inspect the AndroidManifest.xml created in an APK, using apktool with the following command line:
$ apktool d my-app.apk $ cd my-app $ more AndroidManifest.xml
This technique exploits the config-file element that is described in the Cordova Plugin Specification docs and can also be used to add lines to iOS plist files. See the Cordova plugin documentation link for additional details.
Here is an example of such a plugin for modifying the iOS plist file, specifically for adding a BIS key to the plist file:
<?xml version="1.0" encoding="UTF-8"?><plugin
xmlns="http://apache.org/cordova/ns/plugins/1.0"
id="my-custom-bis-plugin"
version="0.0.2"><name>My Custom BIS Plugin</name><description>Add BIS info to iOS plist file.</description><license>BSD-3</license><preference name="BIS_KEY" /><engines><engine name="cordova" version=">=3.0.0" /></engines><!-- ios --><platform name="ios"><config-file target="*-Info.plist" parent="CFBundleURLTypes"><array><dict><key>ITSAppUsesNonExemptEncryption</key><true/><key>ITSEncryptionExportComplianceCode</key><string>$BIS_KEY</string></dict></array></config-file></platform></plugin>How can I share my Intel XDK app build?
You can send a link to your project via an email invite from your project settings page. However, a login to your account is required to access the file behind the link. Alternatively, you can download the build from the build page, onto your workstation, and push that built image to some location from which you can send a link to that image.
Why does my iOS build fail when I am able to test it successfully on a device and the emulator?
Common reasons include:
- Your App ID specified in the project settings do not match the one you specified in Apple's developer portal.
- The provisioning profile does not match the cert you uploaded. Double check with Apple's developer site that you are using the correct and current distribution cert and that the provisioning profile is still active. Download the provisioning profile again and add it to your project to confirm.
- In Project Build Settings, your App Name is invalid. It should be modified to include only alpha, space and numbers.
How do I add multiple domains in Domain Access?
Here is the primary doc source for that feature.
If you need to insert multiple domain references, then you will need to add the extra references in the intelxdk.config.additions.xml file. This StackOverflow entry provides a basic idea and you can see the intelxdk.config.*.xml files that are automatically generated with each build for the <access origin="xxx" /> line that is generated based on what you provide in the "Domain Access" field of the "Build Settings" panel on the Project Tab.
How do I build more than one app using the same Apple developer account?
On Apple developer, create a distribution certificate using the "iOS* Certificate Signing Request" key downloaded from Intel XDK Build tab only for the first app. For subsequent apps, reuse the same certificate and import this certificate into the Build tab like you usually would.
How do I include search and spotlight icons as part of my app?
Please refer to this article in the Intel XDK documentation. Create anintelxdk.config.additions.xml file in your top level directory (same location as the otherintelxdk.*.config.xml files) and add the following lines for supporting icons in Settings and other areas in iOS*.
<!-- Spotlight Icon --><icon platform="ios" src="res/ios/icon-40.png" width="40" height="40" /><icon platform="ios" src="res/ios/icon-40@2x.png" width="80" height="80" /><icon platform="ios" src="res/ios/icon-40@3x.png" width="120" height="120" /><!-- iPhone Spotlight and Settings Icon --><icon platform="ios" src="res/ios/icon-small.png" width="29" height="29" /><icon platform="ios" src="res/ios/icon-small@2x.png" width="58" height="58" /><icon platform="ios" src="res/ios/icon-small@3x.png" width="87" height="87" /><!-- iPad Spotlight and Settings Icon --><icon platform="ios" src="res/ios/icon-50.png" width="50" height="50" /><icon platform="ios" src="res/ios/icon-50@2x.png" width="100" height="100" />
For more information related to these configurations, visit http://cordova.apache.org/docs/en/3.5.0/config_ref_images.md.html#Icons%20and%20Splash%20Screens.
For accurate information related to iOS icon sizes, visit https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/IconMatrix.html
NOTE: The iPhone 6 icons will only be available if iOS* 7 or 8 is the target.
Cordova iOS* 8 support JIRA tracker: https://issues.apache.org/jira/browse/CB-7043
Does Intel XDK support Modbus TCP communication?
No, since Modbus is a specialized protocol, you need to write either some JavaScript* or native code (in the form of a plugin) to handle the Modbus transactions and protocol.
How do I sign an Android* app using an existing keystore?
New with release 3088 of the Intel XDK, you may now import your existing keystore into Intel XDK using the new certificate manager that is built into the Intel XDK. Please read the initial paragraphs of Managing Certificates for your Intel XDK Account and the section titled "Import an Android Certificate Keystore" in that document, for details regarding how to do this.
If the above fails, please send an email to html5tools@intel.com requesting help. It is important that you send that email from the email address associated with your Intel XDK account.
How do I build separately for different Android* versions?
Under the Projects Panel, you can select the Target Android* version under the Build Settings collapsible panel. You can change this value and build your application multiple times to create numerous versions of your application that are targeted for multiple versions of Android*.
How do I display the 'Build App Now' button if my display language is not English?
If your display language is not English and the 'Build App Now' button is proving to be troublesome, you may change your display language to English which can be downloaded by a Windows* update. Once you have installed the English language, proceed to Control Panel > Clock, Language and Region > Region and Language > Change Display Language.
How do I update my Intel XDK version?
When an Intel XDK update is available, an Update Version dialog box lets you download the update. After the download completes, a similar dialog lets you install it. If you did not download or install an update when prompted (or on older versions), click the package icon next to the orange (?) icon in the upper-right to download or install the update. The installation removes the previous Intel XDK version.
How do I import my existing HTML5 app into the Intel XDK?
If your project contains an Intel XDK project file (<project-name>.xdk) you should use the "Open an Intel XDK Project" option located at the bottom of the Projects List on the Projects tab (lower left of the screen, round green "eject" icon, on the Projects tab). This would be the case if you copied an existing Intel XDK project from another system or used a tool that exported a complete Intel XDK project.
If your project does not contain an Intel XDK project file (<project-name>.xdk) you must "import" your code into a new Intel XDK project. To import your project, use the "Start a New Project" option located at the bottom of the Projects List on the Projects tab (lower left of the screen, round blue "plus" icon, on theProjects tab). This will open the "Samples, Demos and Templates" page, which includes an option to "Import Your HTML5 Code Base." Point to the root directory of your project. The Intel XDK will attempt to locate a file named index.html in your project and will set the "Source Directory" on the Projects tab to point to the directory that contains this file.
If your imported project did not contain an index.html file, your project may be unstable. In that case, it is best to delete the imported project from the Intel XDK Projects tab ("x" icon in the upper right corner of the screen), rename your "root" or "main" html file to index.html and import the project again. Several components in the Intel XDK depend on this assumption that the main HTML file in your project is named index.hmtl. See Introducing Intel® XDK Development Tools for more details.
It is highly recommended that your "source directory" be located as a sub-directory inside your "project directory." This insures that non-source files are not included as part of your build package when building your application. If the "source directory" and "project directory" are the same it results in longer upload times to the build server and unnecessarily large application executable files returned by the build system. See the following images for the recommended project file layout.
I am unable to login to App Preview with my Intel XDK password.
On some devices you may have trouble entering your Intel XDK login password directly on the device in the App Preview login screen. In particular, sometimes you may have trouble with the first one or two letters getting lost when entering your password.
Try the following if you are having such difficulties:
Reset your password, using the Intel XDK, to something short and simple.
Confirm that this new short and simple password works with the XDK (logout and login to the Intel XDK).
Confirm that this new password works with the Intel Developer Zone login.
Make sure you have the most recent version of Intel App Preview installed on your devices. Go to the store on each device to confirm you have the most recent copy of App Preview installed.
Try logging into Intel App Preview on each device with this short and simple password. Check the "show password" box so you can see your password as you type it.
If the above works, it confirms that you can log into your Intel XDK account from App Preview (because App Preview and the Intel XDK go to the same place to authenticate your login). When the above works, you can go back to the Intel XDK and reset your password to something else, if you do not like the short and simple password you used for the test.
How do I completely uninstall the Intel XDK from my system?
Take the following steps to completely uninstall the XDK from your Windows system:
From the Windows Control Panel, remove the Intel XDK, using the Windows uninstall tool.
Then:
> cd %LocalAppData%\Intel\XDK> del *.* /s/qThen:
> cd %LocalAppData%\XDK> copy global-settings.xdk %UserProfile%> del *.* /s/q> copy %UserProfile%\global-settings.xdk .- Then:
-- Goto xdk.intel.com and select the download link.
-- Download and install the new XDK.
To do the same on a Linux or Mac system:
- On a Linux machine, run the uninstall script, typically
/opt/intel/XDK/uninstall.sh.
- Remove the directory into which the Intel XDK was installed.
-- Typically/opt/intelor your home (~) directory on a Linux machine.
-- Typically in the/Applications/Intel XDK.appdirectory on a Mac.
- Then:
$ find ~ -name global-settings.xdk
$ cd <result-from-above> (for example ~/Library/Application Support/XDK/ on a Mac)
$ cp global-settings.xdk ~
$ rm -Rf *
$ mv ~/global-settings.xdk .
- Then:
-- Goto xdk.intel.com and select the download link.
-- Download and install the new XDK.
Is there a tool that can help me highlight syntax issues in Intel XDK?
Yes, you can use the various linting tools that can be added to the Brackets editor to review any syntax issues in your HTML, CSS and JS files. Go to the "File > Extension Manager..." menu item and add the following extensions: JSHint, CSSLint, HTMLHint, XLint for Intel XDK. Then, review your source files by monitoring the small yellow triangle at the bottom of the edit window (a green check mark indicates no issues).
How do I delete built apps and test apps from the Intel XDK build servers?
You can manage them by logging into: https://appcenter.html5tools-software.intel.com/csd/controlpanel.aspx. This functionality will eventually be available within Intel XDK after which access to app center will be removed.
I need help with the App Security API plugin; where do I find it?
Visit the primary documentation book for the App Security API and see this forum post for some additional details.
When I install my app or use the Debug tab Avast antivirus flags a possible virus, why?
If you are receiving a "Suspicious file detected - APK:CloudRep [Susp]" message from Avast anti-virus installed on your Android device it is due to the fact that you are side-loading the app (or the Intel XDK Debug modules) onto your device (using a download link after building or by using the Debug tab to debug your app), or your app has been installed from an "untrusted" Android store. See the following official explanation from Avast:
Your application was flagged by our cloud reputation system. "Cloud rep" is a new feature of Avast Mobile Security, which flags apks when the following conditions are met:
- The file is not prevalent enough; meaning not enough users of Avast Mobile Security have installed your APK.
- The source is not an established market (Google Play is an example of an established market).
If you distribute your app using Google Play (or any other trusted market) your users should not see any warning from Avast.
Following are some of the Avast anti-virus notification screens you might see on your device. All of these are perfectly normal, they are due to the fact that you must enable the installation of "non-market" apps in order to use your device for debug and the App IDs associated with your never published app or the custom debug modules that the Debug tab in the Intel XDK builds and installs on your device will not be found in a "established" (aka "trusted") market, such as Google Play.
If you choose to ignore the "Suspicious app activity!" threat you will not receive a threat for that debug module any longer. It will show up in the Avast 'ignored issues' list. Updates to an existing, ignored, custom debug module should continue to be ignored by Avast. However, new custom debug modules (due to a new project App ID or a new version of Crosswalk selected in your project's Build Settings) will result in a new warning from the Avast anti-virus tool.
How do I add a Brackets extension to the editor that is part of the Intel XDK?
The number of Brackets extensions that are provided in the built-in edition of the Brackets editor are limited to insure stability of the Intel XDK product. Not all extensions are compatible with the edition of Brackets that is embedded within the Intel XDK. Adding incompatible extensions can cause the Intel XDK to quit working.
Despite this warning, there are useful extensions that have not been included in the editor and which can be added to the Intel XDK. Adding them is temporary, each time you update the Intel XDK (or if you reinstall the Intel XDK) you will have to "re-add" your Brackets extension. To add a Brackets extension, use the following procedure:
- exit the Intel XDK
- download a ZIP file of the extension you wish to add
- on Windows, unzip the extension here:
%LocalAppData%\Intel\XDK\xdk\brackets\b\extensions\dev - on Mac OS X, unzip the extension here:
/Applications/Intel\ XDK.app/Contents/Resources/app.nw/brackets/b/extensions/dev - start the Intel XDK
Note that the locations given above are subject to change with new releases of the Intel XDK.
Why does my app or game require so many permissions on Android when built with the Intel XDK?
When you build your HTML5 app using the Intel XDK for Android or Android-Crosswalk you are creating a Cordova app. It may seem like you're not building a Cordova app, but you are. In order to package your app so it can be distributed via an Android store and installed on an Android device, it needs to be built as a hybrid app. The Intel XDK uses Cordova to create that hybrid app.
A pure Cordova app requires the NETWORK permission, it's needed to "jump" between your HTML5 environment and the native Android environment. Additional permissions will be added by any Cordova plugins you include with your application; which permissions are includes are a function of what that plugin does and requires.
Crosswalk for Android builds also require the NETWORK permission, because the Crosswalk image built by the Intel XDK includes support for Cordova. In addition, current versions of Crosswalk (12 and 14 at the time this FAQ was written)also require NETWORK STATE and WIFI STATE. There is an extra permission in some versions of Crosswalk (WRITE EXTERNAL STORAGE) that is only needed by the shared model library of Crosswalk, we have asked the Crosswalk project to remove this permission in a future Crosswalk version.
If you are seeing more than the following five permissions in your XDK-built Crosswalk app:
- android.permission.INTERNET
- android.permission.ACCESS_NETWORK_STATE
- android.permission.ACCESS_WIFI_STATE
- android.permission.INTERNET
- android.permission.WRITE_EXTERNAL_STORAGE
then you are seeing permissions that have been added by some plugins. Each plugin is different, so there is no hard rule of thumb. The two "default" core Cordova plugins that are added by the Intel XDK blank templates (device and splash screen) do not require any Android permissions.
BTW: the permission list above comes from a Crosswalk 14 build. Crosswalk 12 builds do not included the last permission; it was added when the Crosswalk project introduced the shared model library option, which started with Crosswalk 13 (the Intel XDK does not support 13 builds).
How do I make a copy of an existing Intel XDK project?
If you just need to make a backup copy of an existing project, and do not plan to open that backup copy as a project in the Intel XDK, do the following:
- Exit the Intel XDK.
- Copy the entire project directory:
- on Windows, use File Explorer to "right-click" and "copy" your project directory, then "right-click" and "paste"
- on Mac use Finder to "right-click" and then "duplicate" your project directory
- on Linux, open a terminal window, "cd" to the folder that contains your project, and type "cp -a old-project/ new-project/" at the terminal prompt (where "old-project/" is the folder name of your existing project that you want to copy and "new-project/" is the name of the new folder that will contain a copy of your existing project)
If you want to use an existing project as the starting point of a new project in the Intel XDK. The process described below will insure that the build system does not confuse the ID in your old project with that stored in your new project. If you do not follow the procedure below you will have multiple projects using the same project ID (a special GUID that is stored inside the Intel XDK <project-name>.xdk file in the root directory of your project). Each project in your account must have a unique project ID.
- Exit the Intel XDK.
- Make a copy of your existing project using the process described above.
- Inside the new project that you made (that is, your new copy of your old project), make copies of the
<project-name>.xdkfile and<project-name>.xdkefiles and rename those copies to something likeproject-new.xdkandproject-new.xdke(anything you like, just something different than the original project name, preferably the same name as the new project folder in which you are making this new project). - Using a TEXT EDITOR (only) (such as Notepad or Sublime or Brackets or some other TEXT editor), open your new "
project-new.xdk" file (whatever you named it) and find theprojectGuidline, it will look something like this:"projectGuid": "a863c382-ca05-4aa4-8601-375f9f209b67", - Change the "GUID" to all zeroes, like this:
"00000000-0000-0000-000000000000" - Save the modified "
project-new.xdk" file. - Open the Intel XDK.
- Goto the Projects tab.
- Select "Open an Intel XDK Project" (the green button at the bottom left of the Projects tab).
- To open this new project, locate the new "
project-new.xdk" file inside the new project folder you copied above. - Don't forget to change the App ID in your new project. This is necessary to avoid conflicts with the project you copied from, in the store and when side-loading onto a device.
My project does not include a www folder. How do I fix it so it includes a www or source directory?
The Intel XDK HTML5 and Cordova project file structures are meant to mimic a standard Cordova project. In a Cordova (or PhoneGap) project there is a subdirectory (or folder) named www that contains all of the HTML5 source code and asset files that make up your application. For best results, it is advised that you follow this convention, of putting your source inside a "source directory" inside of your project folder.
This most commonly happens as the result of exporting a project from an external tool, such as Construct2, or as the result of importing an existing HTML5 web app that you are converting into a hybrid mobile application (eg., an Intel XDK Corodova app). If you would like to convert an existing Intel XDK project into this format, follow the steps below:
- Exit the Intel XDK.
- Copy the entire project directory:
- on Windows, use File Explorer to "right-click" and "copy" your project directory, then "right-click" and "paste"
- on Mac use Finder to "right-click" and then "duplicate" your project directory
- on Linux, open a terminal window, "cd" to the folder that contains your project, and type "cp -a old-project/ new-project/" at the terminal prompt (where "old-project/" is the folder name of your existing project that you want to copy and "new-project/" is the name of the new folder that will contain a copy of your existing project)
- Create a "www" directory inside the new duplicate project you just created above.
- Move your
index.htmland other source and asset files to the "www" directory you just created -- this is now your "source" directory, located inside your "project" directory (do not move the<project-name>.xdkand xdke files and anyintelxdk.config.*.xmlfiles, those must stay in the root of the project directory) - Inside the new project that you made above (by making a copy of the old project), rename the
<project-name>.xdkfile and<project-name>.xdkefiles to something likeproject-copy.xdkandproject-copy.xdke(anything you like, just something different than the original project, preferably the same name as the new project folder in which you are making this new project). - Using a TEXT EDITOR (only) (such as Notepad or Sublime or Brackets or some other TEXT editor), open the new "
project-copy.xdk" file (whatever you named it) and find the line namedprojectGuid, it will look something like this:"projectGuid": "a863c382-ca05-4aa4-8601-375f9f209b67", - Change the "GUID" to all zeroes, like this:
"00000000-0000-0000-000000000000" - A few lines down find:
"sourceDirectory": "", - Change it to this:
"sourceDirectory": "www", - Save the modified "
project-copy.xdk" file. - Open the Intel XDK.
- Goto the Projects tab.
- Select "Open an Intel XDK Project" (the green button at the bottom left of the Projects tab).
- To open this new project, locate the new "
project-copy.xdk" file inside the new project folder you copied above.
Can I install more than one copy of the Intel XDK onto my development system?
Yes, you can install more than one version onto your development system. However, you cannot run multiple instances of the Intel XDK at the same time. Be aware that new releases sometimes change the project file format, so it is a good idea, in these cases, to make a copy of your project if you need to experiment with a different version of the Intel XDK. See the instructions in a FAQ entry above regarding how to make a copy of your Intel XDK project.
Follow the instructions in this forum post to install more than one copy of the Intel XDK onto your development system.
On Apple OS X* and Linux* systems, does the Intel XDK need the OpenSSL* library installed?
Yes. Several features of the Intel XDK require the OpenSSL library, which typically comes pre-installed on Linux and OS X systems. If the Intel XDK reports that it could not find libssl, go to https://www.openssl.org to download and install it.
I have a web application that I would like to distribute in app stores without major modifications. Is this possible using the Intel XDK?
Yes, if you have a true web app or “client app” that only uses HTML, CSS and JavaScript, it is usually not too difficult to convert it to a Cordova hybrid application (this is what the Intel XDK builds when you create an HTML5 app). If you rely heavily on PHP or other server scripting languages embedded in your pages you will have more work to do. Because your Cordova app is not associated with a server, you cannot rely on server-based programming techniques; instead, you must rewrite any such code to user RESTful APIs that your app interacts with using, for example, AJAX calls.
What is the best training approach to using the Intel XDK for a newbie?
First, become well-versed in the art of client web apps, apps that rely only on HTML, CSS and JavaScript and utilize RESTful APIs to talk to network services. With that you will have mastered 80% of the problem. After that, it is simply a matter of understanding how Cordova plugins are able to extend the JavaScript API for access to features of the platform. For HTML5 training there are many sites providing tutorials. It may also help to read Five Useful Tips on Getting Started Building Cordova Mobile Apps with the Intel XDK, which will help you understand some of the differences between developing for a traditional server-based environment and developing for the Intel XDK hybrid Cordova app environment.
What is the best platform to start building an app with the Intel XDK? And what are the important differences between the Android, iOS and other mobile platforms?
There is no one most important difference between the Android, iOS and other platforms. It is important to understand that the HTML5 runtime engine that executes your app on each platform will vary as a function of the platform. Just as there are differences between Chrome and Firefox and Safari and Internet Explorer, there are differences between iOS 9 and iOS 8 and Android 4 and Android 5, etc. Android has the most significant differences between vendors and versions of Android. This is one of the reasons the Intel XDK offers the Crosswalk for Android build option, to normalize and update the Android issues.
In general, if you can get your app working well on Android (or Crosswalk for Android) first you will generally have fewer issues to deal with when you start to work on the iOS and Windows platforms. In addition, the Android platform has the most flexible and useful debug options available, so it is the easiest platform to use for debugging and testing your app.
Is my password encrypted and why is it limited to fifteen characters?
Yes, your password is stored encrypted and is managed by https://signin.intel.com. Your Intel XDK userid and password can also be used to log into the Intel XDK forum as well as the Intel Developer Zone. the Intel XDK does not store nor does it manage your userid and password.
The rules regarding allowed userids and passwords are answered on this Sign In FAQ page, where you can also find help on recovering and changing your password.
Why does the Intel XDK take a long time to start on Linux or Mac?
...and why am I getting this error message? "Attempt to contact authentication server is taking a long time. You can wait, or check your network connection and try again."
At startup, the Intel XDK attempts to automatically determine the proxy settings for your machine. Unfortunately, on some system configurations it is unable to reliably detect your system proxy settings. As an example, you might see something like this image when starting the Intel XDK.
On some systems you can get around this problem by setting some proxy environment variables and then starting the Intel XDK from a command-line that includes those configured environment variables. To set those environment variables, similar to the following:
$ export no_proxy="localhost,127.0.0.1/8,::1" $ export NO_PROXY="localhost,127.0.0.1/8,::1" $ export http_proxy=http://proxy.mydomain.com:123/ $ export HTTP_PROXY=http://proxy.mydomain.com:123/ $ export https_proxy=http://proxy.mydomain.com:123/ $ export HTTPS_PROXY=http://proxy.mydomain.com:123/
IMPORTANT! The name of your proxy server and the port (or ports) that your proxy server requires will be different than those shown in the example above. Please consult with your IT department to find out what values are appropriate for your site. Intel has no way of knowing what configuration is appropriate for your network.
If you use the Intel XDK in multiple locations (at work and at home), you may have to change the proxy settings before starting the Intel XDK after switching to a new network location. For example, many work networks use a proxy server, but most home networks do not require such a configuration. In that case, you need to be sure to "unset" the proxy environment variables before starting the Intel XDK on a non-proxy network.
After you have successfully configured your proxy environment variables, you can start the Intel XDK manually, from the command-line.
On a Mac, where the Intel XDK is installed in the default location, type the following (from a terminal window that has the above environment variables set):
$ open /Applications/Intel\ XDK.app/
On a Linux machine, assuming the Intel XDK has been installed in the ~/intel/XDK directory, type the following (from a terminal window that has the above environment variables set):
$ ~/intel/XDK/xdk.sh &
In the Linux case, you will need to adjust the directory name that points to the xdk.sh file in order to start. The example above assumes a local install into the ~/intel/XDK directory. Since Linux installations have more options regarding the installation directory, you will need to adjust the above to suit your particular system and install directory.

How do I change the default dir for creating new projects in the Intel XDK?
You can change the default new project location manually by modifying a field in the global-settings.xdk file. Locate the global-settings.xdk file on your system (the precise location varies as a function of the OS) and find this JSON object inside that file:
"projects-tab": {"defaultPath": "/Users/paul/Documents/XDK","LastSortType": "descending|Name","lastSortType": "descending|Opened","thirdPartyDisclaimerAcked": true
},The example above came from a Mac. On a Mac the global-settings.xdk file is located in the "~/Library/Application Support/XDK" directory.
On a Windows machine the global-settings.xdk file is normally found in the "%LocalAppData%\XDK" directory. The part you are looking for will look something like this:
"projects-tab": {"thirdPartyDisclaimerAcked": false,"LastSortType": "descending|Name","lastSortType": "descending|Opened","defaultPath": "C:\\Users\\paul/Documents"
},Obviously, it's the defaultPath part you want to change.
BE CAREFUL WHEN YOU EDIT THE GLOBAL-SETTINGS.XDK FILE!! You've been warned...
Make sure the result is proper JSON when you are done, or it may cause your XDK to cough and hack loudly. Make a backup copy of global-settings.xdk before you start, just in case.
Where I can find recent and upcoming webinars list?
How can I change the email address associated with my Intel XDK login?
Login to the Intel Developer Zone with your Intel XDK account userid and password and then locate your "account dashboard." Click the "pencil icon" next to your name to open the "Personal Profile" section of your account, where you can edit your "Name & Contact Info," including the email address associated with your account, under the "Private" section of your profile.
What network addresses must I enable in my firewall to insure the Intel XDK will work on my restricted network?
Normally, access to the external servers that the Intel XDK uses is handled automatically by your proxy server. However, if you are working in an environment that has restricted Internet access and you need to provide your IT department with a list of URLs that you need access to in order to use the Intel XDK, then please provide them with the following list of domain names:
- appcenter.html5tools-software.intel.com (for communication with the build servers)
- s3.amazonaws.com (for downloading sample apps and built apps)
- download.xdk.intel.com (for getting XDK updates)
- debug-software.intel.com (for using the Test tab weinre debug feature)
- xdk-feed-proxy.html5tools-software.intel.com (for receiving the tweets in the upper right corner of the XDK)
- signin.intel.com (for logging into the XDK)
- sfederation.intel.com (for logging into the XDK)
Normally this should be handled by your network proxy (if you're on a corporate network) or should not be an issue if you are working on a typical home network.
I cannot create a login for the Intel XDK, how do I create a userid and password to use the Intel XDK?
If you have downloaded and installed the Intel XDK but are having trouble creating a login, you can create the login outside the Intel XDK. To do this, go to the Intel Developer Zone and push the "Join Today" button. After you have created your Intel Developer Zone login you can return to the Intel XDK and use that userid and password to login to the Intel XDK. This same userid and password can also be used to login to the Intel XDK forum.
Installing the Intel XDK on Windows fails with a "Package signature verification failed." message.
If you receive a "Package signature verification failed" message (see image below) when installing the Intel XDK on your system, it is likely due to one of the following two reasons:
- Your system does not have a properly installed "root certificate" file, which is needed to confirm that the install package is good.
- The install package is corrupt and failed the verification step.
The first case can happen if you are attempting to install the Intel XDK on an unsupported version of Windows. The Intel XDK is only supported on Microsoft Windows 7 and higher. If you attempt to install on Windows Vista (or earlier) you may see this verification error. The workaround is to install the Intel XDK on a Windows 7 or greater machine.
The second case is likely due to a corruption of the install package during download or due to tampering. The workaround is to re-download the install package and attempt another install.
If you are installing on a Windows 7 (or greater) machine and you see this message it is likely due to a missing or bad root certificate on your system. To fix this you may need to start the "Certificate Propagation" service. Open the Windows "services.msc" panel and then start the "Certificate Propagation" service.

Troubles installing the Intel XDK on a Linux or Ubuntu system, which option should I choose?
Choose the local user option, not root or sudo, when installing the Intel XDK on your Linux or Ubuntu system. This is the most reliable and trouble-free option and is the default installation option. This will insure that the Intel XDK has all the proper permissions necessary to execute properly on your Linux system. The Intel XDK will be installed in a subdirectory of your home (~) directory.
Inactive account/ login issue/ problem updating an APK in store, How do I request account transfer?
As of June 26, 2015 we migrated all of Intel XDK accounts to the more secure intel.com login system (the same login system you use to access this forum).
We have migrated nearly all active users to the new login system. Unfortunately, there are a few active user accounts that we could not automatically migrate to intel.com, primarily because the intel.com login system does not allow the use of some characters in userids that were allowed in the old login system.
If you have not used the Intel XDK for a long time prior to June 2015, your account may not have been automatically migrated. If you own an "inactive" account it will have to be manually migrated -- please try logging into the Intel XDK with your old userid and password, to determine if it no longer works. If you find that you cannot login to your existing Intel XDK account, and still need access to your old account, please send a message to html5tools@intel.com and include your userid and the email address associated with that userid, so we can guide you through the steps required to reactivate your old account.
Alternatively, you can create a new Intel XDK account. If you have submitted an app to the Android store from your old account you will need access to that old account to retrieve the Android signing certificates in order to upgrade that app on the Android store; in that case, send an email to html5tools@intel.com with your old account username and email and new account information.
Connection Problems? -- Intel XDK SSL certificates update
On January 26, 2016 we updated the SSL certificates on our back-end systems to SHA2 certificates. The existing certificates were due to expire in February of 2016. We have also disabled support for obsolete protocols.
If you are experiencing persistent connection issues (since Jan 26, 2016), please post a problem report on the forum and include in your problem report:
- the operation that failed
- the version of your XDK
- the version of your operating system
- your geographic region
- and a screen capture
How do I resolve build failure: "libpng error: Not a PNG file"?
f you are experiencing build failures with CLI 5 Android builds, and the detailed error log includes a message similar to the following:
Execution failed for task ':mergeArmv7ReleaseResources'.> Error: Failed to run command: /Developer/android-sdk-linux/build-tools/22.0.1/aapt s -i .../platforms/android/res/drawable-land-hdpi/screen.png -o .../platforms/android/build/intermediates/res/armv7/release/drawable-land-hdpi-v4/screen.png Error Code: 42 Output: libpng error: Not a PNG file
You need to change the format of your icon and/or splash screen images to PNG format.
The error message refers to a file named "screen.png" -- which is what each of your splash screens were renamed to before they were moved into the build project resource directories. Unfortunately, JPG images were supplied for use as splash screen images, not PNG images. So the files were renamed and found by the build system to be invalid.
Convert your splash screen images to PNG format. Renaming JPG images to PNG will not work! You must convert your JPG images into PNG format images using an appropriate image editing tool. The Intel XDK does not provide any such conversion tool.
Beginning with Cordova CLI 5, all icons and splash screen images must be supplied in PNG format. This applies to all supported platforms. This is an undocumented "new feature" of the Cordova CLI 5 build system that was implemented by the Apache Cordova project.
Why do I get a "Parse Error" when I try to install my built APK on my Android device?
Because you have built an "unsigned" Android APK. You must click the "signed" box in the Android Build Settings section of the Projects tab if you want to install an APK on your device. The only reason you would choose to create an "unsigned" APK is if you need to sign it manually. This is very rare and not the normal situation.
