You don't need to draw the whole Activity over. If you set a bitmap
into an ImageView, Android will render that after your code completes
its current run and allows the UI thread to process that change. You
need to put each frame into the ImageView followed by some delay. You
can use a Handler to schedule delays on the UI thread.
