Hallo,
Habe ein kleines Problem. Ich versuche mich gerade an einem Batterie-Widget, welches mit einem Service im Hintergrund den Status aktualisiert. Das funktioniert auch soweit. Nun möchte ich, dass man beim hinzufügen auf dem Homescreen zuerst eine Config-Activity sieht:
Manifest:
AppWidgetProvider:
Config-Activity:
Service:
Widget.xml:
Mein Problem ist jetzt, wie bekomme ich im Service die Prefs zu der widgetId?
Grüße
Fabi
