How are we supposed to remove the onTouchListener when our Activity gets destroyed?
There is a setOnTouchlistener but no remove.
Setting it to null won't work - you will throw an exception.
This is important because you are holding on to the reference and our activity can't be garbage collected, causing a huge memory leak.
We have used removeListeners for Scale and NavigationChanged.
The only thing I can think of now is to create a DummyonTouchListener that does nothing, and set it in onDestroy.
