i download it tutorial for finger paint. This app use surface view to implement painting.

However, I find that the drawing thread is locked and the system cannot unlock it when i close the app and reopen the app for four and five times.

Method call flow: surfaceCreated -> start drawing thread -> surfaceChanged -> setSurfaceSize()

In the setSurfaceSize synchronized (pThread) <---wait for drawing thread

However, sometime the thread is not unlocked by the system.

Anyone know what the problem is?

Thanks.

from your description sounds like a deadlock may be, but without actual code really hard to see. – Eugene Aug 19 '12 at 10:55
but, it sometimes work fine. Restart the app for four times. It cannot start app. I have no idea. – King Wu Aug 19 '12 at 15:02
without actual code it is impossible to tell where the problem is – Eugene Aug 19 '12 at 16:45
