I am creating a phonegap application for capturing photos on Android phones. Its works fine for android 4.x. but does not work for android 2.3.x

there was an error:

Excuse me! AppName (packagename) stopped unexpectedly. Please try again.

I created the project as mentioned here and using the full example.

My html phonegep page:

The Phonegap camera plugin (Cordova) by default calls its own camera, and this causes the Android Garbage Collector to kill background applications. This plugin does not allow your application to go in the background and be killed by the garbage collector in other applications. We used the source code of Phonegap and modified it to avoid this problem. This plugin only works with a file URI.

Instead of destinationType.FILE_URI use Camera.DestinationType.FILE_URI

See the following code

 navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50, destinationType: Camera.DestinationType.FILE_URI });

It works for me on 2.3.x as well as on 4.x

Hope this helps.
