Detect deviation from selected route in android map

Question

I want to draw route between two points. I did this successfully. But how to know if the user deviated from drawn path or not. So that I can suggest user to notify alternative path to reach their destination. Like what google map navigation did. Am working on it and till now I could't find any answer for this. Please suggest some approach to me to find deviation from selected route.

Thanks in advance.

Use PolyUtil.isLocationOnPath(...) from Google Maps Android API utility library.
