post https://stackoverflow.com/questions/1430741/how-to-draw-lots-of-bitmaps-on-screen-in-an-android-game-without-slow-performance

UPDATE

I've identified the problem. And it is the fact that my player updates the same rate as the background scrolls (making it look choppy). from top to bottom. This is because both get drawn in the same function. I'm not really sure how to tackle this and would be grateful for any help. i.e so that player movement is handled separately from the map scrolling

Also how can I control the speed at which onDraw(canvas) get called?

Thanks in advance.

However, I have patched together a different run loop for anyone having the same problem. This is partially from the jetboy example on google.

Below is my inner class in my surfaceview

UPDATE & SOLUTION

Thank you for everyone helping me. I came across this:

Helped my problem a lot. However, Seemed I was creating bitmaps in the onDraw every time is was caused, meaning that was doing 95% of the slowing down. oops :)

class MapThread extends Thread{

    @Override

                Canvas c = null;

                 try {
                       c = holder.lockCanvas(null);
                       synchronized (holder) {
                            map.onDraw(c);
                     }
                 } finally {

                     if (c != null) {
                         holder.unlockCanvasAndPost(c);
                     }
                 }
        }
    }
