How to track path direction in android?

Question

I am having a View class where I am drawing paths through finger touch(bitmaps and canvas). I need to keep track of the direction of path while my finger is moving on it. Android developer page doesn't give much information on Path.Direction. Any help with this?

You need to add an OnMotionEvent listener to your view and either use a Gesture Detector or manually work out the difference in X and Y axis and track the movement yourself
