###Attention: Currently a bug in Android 5. 1. 0 crashes the app, if you check "Don't show again" at the initial dialog granting the app the rights to record the screen. To avoid the bug, don't hit "Don't show again", if you already did so, uninstall and install the app again. With Android 5. 1. 1 the bug is resolved, see. Com/p/android/issues/detail?
