BUILD FAILED, NullPointerException from “sencha app build native”

I'm trying to get my Sencha App to work on Android devices.

I'm running;

  • Windows 8
  • Sencha Architect 3
  • Sencha Touch 2.3.1
  • Sencha Cmd 4.0.2.67
  • Cordova 3.4.0-0.1.3
  • Phonegap 3.4.0-0.19.7

I had an app working in my local browser when I ran the localhost called DemoApp. I went into my terminal into the app directory and ran cordova platform add android and it was successful. But when I run sencha app build native I get the following error. 

[ERR] BUILD FAILED
[ERR] java.lang.NullPointerException
[ERR] 
[ERR] The error occurred while executing this line: 
[ERR] C:\Projects\DemoApp\.sencha\app\build-impl.xml:291: 
The following error occurred while executing this line:
C:\Projects\DemoApp\.sencha\app\resources-impl.xml:7: 
java.lang.NullPointerException

I honestly have no clue what to do here. I've Google'd the problem and all i can find is Unanswered questions in the Sencha Forums.

I figured it out.

The app I was trying to put on mobile devices was generated by Sencha Architect using the ExtJS framework, not the Sencha-Touch framework. When I made a simple Sencha-Touch app and followed these steps it worked and I was able to put it on my mobile device.

C:\Projects\DemoApp> sencha phonegap init
C:\Projects\DemoApp> cd phonegap
C:\Projects\DemoApp\phonegap> cordova platform add android
C:\Projects\DemoApp\phonegap> cd ..
C:\Projects\DemoApp> sencha app build native

After this you should be able to run the app on your emulater/device however you would do so.
