Answer 1

Thanks to @kaho, for this "I think you can use +to:waypoint after the destination address."

This works for me with multiple way points:

  RealmList list = routeEntity.getStops();
  ArrayList> latLang = new ArrayList<>();

  for (LocationEntity location: list){
    latLang.add(location.toMap());
  }


  String jsonURL = "https://maps.google.com/maps?";
  final StringBuffer sBuf = new StringBuffer(jsonURL);
  sBuf.append("saddr=");
  sBuf.append(destLat);
  sBuf.append(',');
  sBuf.append(destLong);
  sBuf.append("&daddr=");
  sBuf.append(sourceLat);
  sBuf.append(',');
  sBuf.append(sourceLong);
  sBuf.append("+to:");
  sBuf.append(latLang.get(0).get("latitude"));
  sBuf.append(',');
  sBuf.append(latLang.get(0).get("longitude"));
  sBuf.append("+to:");
  sBuf.append(latLang.get(1).get("latitude"));
  sBuf.append(',');
  sBuf.append(latLang.get(1).get("longitude"));
  sBuf.append("+to:");
  sBuf.append(latLang.get(2).get("latitude"));
  sBuf.append(',');
  sBuf.append(latLang.get(2).get("longitude"));
  sBuf.append("+to:");
  sBuf.append(latLang.get(3).get("latitude"));
  sBuf.append(',');
  sBuf.append(latLang.get(3).get("longitude"));
  sBuf.append("+to:");
  sBuf.append(latLang.get(4).get("latitude"));
  sBuf.append(',');
  sBuf.append(latLang.get(4).get("longitude"));

  // sBuf.append("&sensor=true&mode=DRIVING");
  sBuf.append("&key=");
  sBuf.append("Your_API_KEY");

  MISLog.printDebug(sBuf);

  Intent sendLocationToMap = new Intent(Intent.ACTION_VIEW,
    Uri.parse(sBuf.toString()));
  startActivity(sendLocationToMap);
