Android App High Cpu-usage

I am programming a app that has to do a operation with high cpu usage on a longer time the operation is startet like a service but the android system kills the app because of the h

Solution 1:

You can try divide the operation into smaller pieces and place Thread.sleep() for a short time. If that's not enough try changing some code into loop like this:

Old code:

object.move(1000);

New code:

for (int i=0; i<100; i++) {
    object.move(10);
    Thread.sleep(10);
}

If the example move() operation takes more time if the given parameter is higher, the old code can cause your program non-responding. The new code will allow android to comunicate with your program during Thread.sleep(), so your app shoud not stop working.

@edit As I can see in your code - you do have several while loops. Try placing Thread.sleep(10) inside them.

Solution 2:

You're putting this code directly in a Service which runs on the main thread. You need to instead put it in a background thread. Consider using an IntentService instead or start a worker thread from your service.
