Bitte fügen logcat fehlen. Wahrscheinlich haben Sie ein ungültiges Token. – Fiil
Repaliere com.google.android.gms.maps.MapFragment mit com.google.android.gms.maps.SupportMapFragment und überprüfe, ob es funktioniert – Pehlaj
Nein, das funktioniert nicht, aber ich habe es jetzt gelöst, nach zwei Stunden verschwende ich meine Zeit, die ich gefunden habe dass mein Internet nicht funktioniert, aber danke für alles –
