Does this work? I took a 9patch png that works fine if I use it via setBackgroundResource(), but instead loaded the png bytes and decoded them via BitmapFactory to get a Bitmap and used the getNinePatchChunk () method in an attempt to create a NinePatch object from the bitmap. Everything runs ok until the constructor for NinePatch(bitmap, chunk, src) causes the app to crash... no stacktrace, but a ton of internal debug diagnostics are sent to logcat... none of which makes any sense to me nor points to the problem.
