remove android:targetSdkVersion from AndroidManifest that is conflict with project.properties API target.
I don't know why well..
Here the discussion:
android:installLocation="preferExternal">
<!-- Android 4.4.2 -->
- <uses-sdk android:minSdkVersion="19" android:targetSdkVersion="19" />
+ <uses-sdk android:minSdkVersion="19" />
<!-- OpenGL ES 2.0 -->
<uses-feature android:glEsVersion="0x00020000" />
