Answer 1

I was facing this problem and finally fixed after long time.

public static void filterApply(Filter filter){
    Bitmap bitmcopy = PhotoModel.getInstance().getPhotoCopyBitmap();
    //custom scalling is important to apply filter otherwise it will not apply on image
    Bitmap scaledBitmap = Bitmap.createScaledBitmap(bitmcopy, bitmcopy.getWidth()-1, bitmcopy.getHeight()-1, false);
    filter.processFilter(scaledBitmap);
    filterImage.setImageBitmap(scaledBitmap);
}
