- Unterschied Service - Background Task
- Service: Wenn etwas im Hintergrund laufen muss (z.B. Nuki App)
- BT: z.B Musik Player, immer wenn der User nicht mit der App Interagieren will
Service sollte immmer eine Aktion die er ausführt in einem extra Thread auslagern.
Service wird im Manifest deklariert
Um einen Foregroundservice zu starten muss das innerhalb von 5 Sekunden nach "start Service" (Intent)
Notifications benötigen immer einen Channel (ab Android O verfügbar)
