Ich weiß, dass ähnliche Fragen schon einmal gestellt wurden, aber die Antworten waren nicht perfekt.Geofences funktioniert nicht, wenn App getötet wird
Ich habe eine App mit Geofences mit dem Beispielcode von Android-Entwickler-Website erstellt. Ich habe keine geteilten Einstellungen zum Speichern von Geofences verwendet, da ich die Geofences nicht lösche. Ich teste die App im Geofence, aber mein Smartphone erhält jedes Mal Benachrichtigungen, wenn die App ausgeführt wird, und es werden keine Benachrichtigungen angezeigt, wenn die App beendet wird. Warum passiert das? Ich denke, ich sollte Benachrichtigungen erhalten, auch wenn die App getötet wird.
