What is the best way to render in game loop on android?
When I'm rendering in java I know how to do this. I create buffer strategy, than graphics, I draw, than dispose and than flip buffer. Is there Andorid equivalent of that?
I looked into view, but it doesn't work correctly when I try draw a lot. I looked into SurfaceView than, but I can't understand how I can refresh drawing on it. invalidate breaks the loop, postInvalidate doesn't work. I lock canvas and draw on it, and than unlock and post in "create" method from surface view (locking canvas in loop doesn't work, only white screen in app appears). So I don't get it.
What's the most efficient way to render heavily in Android?

The common approach to render within a SurfaceView is through its SurfaceHolder.
Usually you'll get a Canvas through the holder and draw on it:
The correct approach is to loop all the code between the
lockCanvas()
andunlockCanvasAndPost()
(inclusive) in a separate thread (the render thread) and control the framerate with aThread.sleep()
inside the loop.EDIT:
There are many ways to control the FPS of the render thread, this is a basic one, just set the wanted FPS on a constant:
