Hi Dianne. My app defines the individual swipes of the user on the drawing canvas as 'gestures', in that each has a start on finger down, an end on finger up, and is in progress in between those two events. When the user is drawing close to the edge of the screen, and touches it, the break in MotionEvents to the gesture detector results in the end of the gesture event being fired off and when their finger is brought back onto the screen, still in the continuous motion, this is registered as an onDown and a new, second stroke is started. So for example, if the user is drawing a stroke in an arc that is meant to go close to the edge but not touch it, but they touch it by accident, there will be two unique strokes that are discontinuous and would not represent the user's intent.
If I can determine that I have an edge case while the gesture is in progress, I am thinking that I may be able to handle this case in a more intuitive or expected manor, for instance signaling my app to not register the second stroke. It's not the end of the world if this is 'the way it is', but was just going to try to play around and see what I could do with the edgeFlags to improve this behavior.
