MapView seems to not offer simple api methods to do that, but you can get route points through map api : https://stackoverflow.com/questions/13911279/simplest-way-to-draw-a-route-on-mapview — smora, Aug 08 '17 at 08:11

If you want to open maps app with a route from your source to destination, you just need to start an activity with following intent.

Uri routeUri = Uri.parse("http://maps.google.com/maps?saddr=your-lat-1,your-lng-1&daddr=your-lat-2,your-lng-2");
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, routeUri);
startActivity(intent);

Replace your-lat/lng-1/2 with your latitude and longitude.
