DrawerLayout prevents call of MainActivity.onTouchEvent()

I have an app that overrides the onTouchEvent(MotionEvent ev) of the MainActivity to determine Two-Finger-Swipe and Pich-Open

Answer 1

Works perfectly with the exception of the "edge" not being taken from android code but as a constant (which I set).
