Here is the code which I am using to access the Bitmap Drawables : Target targetBitmap = new Target() { @Override public void onPrepareLoad(Drawable arg0) { } @Override public void onBitmapLoaded(Bitmap arg0, Picasso.LoadedFrom arg1) { mBitmap = arg0; BitmapDrawable d = new BitmapDrawable(context.getResources(), arg0); int margin = 2;
