Could you please show more code? I don't understand if you're stuck on passing data between activities or on using the map class. — michoprogrammer, Feb 10 '17 at 11:00

You could use Intent:

first put your Long/Lat values with a String key in the Intent you create to start new Activity:

 long lat = 731414;
 long lng = 134145;
 Intent intent = new Intent(this, MapsActivity.class);
 intent.putExtra("LONGITUDE" , lat);
 intent.putExtra("LATITUDE" , lng);
 startActivity(intent);

In the onCreate of MapsActivity you can getIntent and get the extras with the key you put them in:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    long lat = getIntent().getLongExtra("LONGITUDE", 0);
    long lng = getIntent().getLongExtra("LATITUDE" , 0);
