I'm making an application in Android Studio for an event and would like it to:
When you open a specific screen, the app would use mobile phone gps to acquire the source coordinates and open the google maps app to create a route with the destination point at the event location.
Thanks in advance,
Welcome!
Try this:
// URL para abrir o google maps
final String ulrRoute = "https://maps.google.com?saddr=Current+Location&daddr=%s,%s";
// Informe a latitude e longitude do local do evento
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse( String.format(Locale.getDefault(),ulrRoute, "-25.429138", "-49.271481") ));
// Informamos que queremos abrir a Activity MapsActivity do com.google.android.apps.maps
i.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(i);
