Answer 1

To navigate user to destination lat long, we can use something like this

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("http://maps.google.com/maps?daddr=28.605989,77.372970"));
startActivity(intent);

Here . we are passing just destination lat long daddr=28.605989,77.372970, so by default, your current location will be source location.

To add extra information with your url .

String my_data= String.format(Locale.ENGLISH, "http://maps.google.com/maps?daddr=20.5666,45.345(My Destination Place)");

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(my_data));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);

You can send intent to Google Map android application by following code:

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("http://maps.google.com/maps?saddr=22.458,34.34&daddr=75.124,35.448"));
startActivity(intent);

In the above URI saddr represents the source address i.e. your current location and daddr represents the coordinates of the destination location.
