Camera activity crashes after screen unlock

[Jame584]

I've noticed that the app crashes (i've tried also the TwoInputFilterExample) everytime i lock the screen with the camera activity on focus and then i unlock the screen.
I've tried to manage this with onStop/onRestart but this solve the issue only on some devices (Asus TF201, Galaxy S4) but not in others (Galaxy S, S2).

Hi! I've tried, on a Nexus 4, the AllFiltersExample bundled with this framework and this bug occurs when i lock and then unlock the screen or i receive a phone call.

This is the logcat

then, i've tried to switch "super.onPause();" with "((CameraPreviewInput) input).onPause();" in the onPause method and it crashes with this logcat
