For us to help you better, you need to provide details on what you have tried so far or the code which didn't work.

In general, if you need to open a map, which shows directions from point A to point B, here is a code that works.

 Uri.Builder directionsBuilder = new Uri.Builder()
                .scheme("https")
                .authority("www.google.com")
                .appendPath("maps")
                .appendPath("dir")
                .appendPath("")
                .appendQueryParameter("api", "1")
                .appendQueryParameter("destination", latitude + "," + longitude);

        startActivity(new Intent(Intent.ACTION_VIEW, directionsBuilder.build()));
