scratchView onProgress always returns 0

[tao101]

private int getPercent(){
        perc = 0;
        scratchView.setEraseStatusListener(new ScratchView.EraseStatusListener() {
            @Override
            public void onProgress(int percent) {
                perc = percent;
            }

            @Override
            public void onCompleted(View view) {

            }
        });


        return perc;
    }

use
executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, width, height);
instead of
execute(width, height);

inside onErase() method.
