Android ANR SurfaceView
I keep getting ANRs sometimes if i start a new Activity from a running Activity that has a SurfaceView. Does anyone know what this lock is about? I use android support package to use fragments, my surfaceview is in a fragment.

Ok I finally found it. The Callback.surfaceDestroyed did not wait for my paint thread to release the canvas lock, and now if I start a new Activity the SurfaceView.updateWindow is waiting for the unlock
