Building a 9 patch drawable at runtime

Question

I am successfully building a 9patch drawable at runtime on Android 3.0+ using the excellent gist provided by Brian Griffey (found here).

Essentially I load the raw (

It's working for me after I updated the code. I think the color size made it unhappy for some reason(Based on the comments in the android source code each patch has a color hint, setting fewer than the number of sections in this case 9 appears to cause problems). I haven't tested with your image yet.

public static NinePatch createFixedNinePatch(Resources res, Bitmap bitmap, int top, int left, int bottom, int right, String srcName){
    ByteBuffer buffer = getByteBufferFixed(top, left, bottom, right);
    NinePatch patch = new NinePatch(bitmap, buffer.array(), srcName);
    return patch;
}

public static ByteBuffer getByteBufferFixed(int top, int left, int bottom, int right) {
    //Docs check the NinePatchChunkFile
    ByteBuffer buffer = ByteBuffer.allocate(84).order(ByteOrder.nativeOrder());
    //was translated
    buffer.put((byte)0x01);
    //divx size
    buffer.put((byte)0x02);
    //divy size
    buffer.put((byte)0x02);
    //color size
    buffer.put(( byte)0x09);

    //skip
    buffer.putInt(0);
    buffer.putInt(0);

    //padding
    buffer.putInt(0);
    buffer.putInt(0);
    buffer.putInt(0);
    buffer.putInt(0);

    //skip 4 bytes
    buffer.putInt(0);

    buffer.putInt(left);
    buffer.putInt(right);
    buffer.putInt(top);
    buffer.putInt(bottom);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    buffer.putInt(NO_COLOR);
    return buffer;
}
