Samples of using the BPG image format on Android.
To build Android-BPG-client you need Eclipse configured for native development. Here is a good tutorial for this: https://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/
To build the project you can now use Android Studio, as the project was updated to use Gradle.
For usage, check the code in MainActivity.java, particularly the getDecodedBitmap function.
