the sence build up by many 16pels*16pels PNG. I want to konw How can i solve this problem and android can do it like Double buffering in j2me ? Thank you

Do you work with SurfaceView?
The cpu usage depend on your game loop. If you draw as fast as possible (without Thread.sleep()) the 50% is normal.
I can recommend a good article for game loop: http://dewitters.koonsolo.com/gameloop.html

As long as your app responces to events and the refresh rate is above 25fps i wouldn't look at cpu usage....
