My app needs to show Google Maps directions from A to B, but I don\'t want to put the Google Maps into my application - instead, I want to launch it using an Intent. Is this
For multiple way points, following can be used as well.
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("https://www.google.com/maps/dir/48.8276261,2.3350114/48.8476794,2.340595/48.8550395,2.300022/48.8417122,2.3028844"));
startActivity(intent);
First set of coordinates are your starting location. All of the next are way points, plotted route goes through.
Just keep adding way points by concating "/latitude,longitude" at the end. There is apparently a limit of 23 way points according to google docs. Not sure if that applies to Android too.
