I think you are running into a RAM or storage problem, as in, not enough to load and install the special App Preview Crosswalk app (APX) that must be installed on your device. According to this page (http://www.devicespecifications.com/en/comparison/b9af2ebd1) your device has only 512 MB of RAM, which is a marginal amount for use with the Debug tab, and 4GB of storage. I've seen problems trying to install APX in the past on devices that have only 512 MB of RAM. The only way I was able to get the APX image installed on an inexpensive tablet I use for testing that also has limited memory was to:
- remove as many apps from RAM as possible before installing APX (reboot the device is the simplest approach)
- make sure there is sufficient storage space in your device (uninstall any unneeded apps on the device)
- install APX by hand
The last step is the hardest, but only if you are uncomfortable with the command-line:
- while attempting to install APX (above) the XDK downloaded a copy of the APK that must be installed on your Android device
- find that APK that contains APX
- install that APK manually onto your Android device using adb
To find the APK, on a Mac:
$ cd ~/Library/Application\ Support/XDK
$ find . -name *apk
To find the APK, on a Windows machine:
> cd %LocalAppData%\XDK
> dir /s *.apk
For each version of Crosswalk that you have attempted to use (via the Debug tab), you will find a copy of the APK file (but only if you have attempted to use the Debug tab and the XDK has successfully downloaded the corresponding version of APX). You should find something similar to:
./apx_download/12.0/AppAnalyzer.apk
following the searches, above. Notice the directory that specifies the Crosswalk version (12.0 in this example). The file named AppAnalyzer.apk is APX and is what you need to install onto your Android device.
Before you install onto your Android device, you can double-check to see if APX is already installed:
- find "Apps" or "Applications" in your Android device's "settings" section
- find "App Preview Crosswalk" in the list of apps on your device (there can be more than one)
If you found one or more App Preview Crosswalk apps on your device, you can see which versions they are by using adb at the command-line (this assumes, of course, that your device is connected via USB and you can communicate with it using adb):
- type "adb devices" at the command-line to confirm you can see your device
- type "adb shell 'pm list packages -f' " at the command-line
- search the output for the word "app_analyzer"
The specific version(s) of APX installed on your device end with a version ID. For example: "com.intel.app_analyzer.v12" means you have APX for Crosswalk 12 installed on your device.
To install a copy of APX manually, cd to the directory containing the version of APX you want to install and then use the following adb command:
$ adb install AppAnalyzer.apk
If you need to remove the v12 copy of APX, due to crowding of available storage space, you can remove it using the following adb command:
$ adb uninstall com.intel.app_analyzer.v12
or
$ adb shell am start -a android.intent.action.DELETE -d package:com.intel.app_analyzer.v12
The second one uses the Android undelete tool to remove the app. You'll have to respond to a request to undelete on the Android device's screen. See this SO issue for details: http://stackoverflow.com/questions/12949609/adb-shell-command-to-make-android-package-uninstall-dialog-appear. Obviously, if you want to uninstall a different version of APX, specify the package ID corresponding to that version of APX.
