Ich stieß auf ein Problem, bei dem meine geplanten Aufgaben nicht mehr funktionierten, sobald ein Gerät neu gestartet wurde. Ich wurde informiert, dass dies normales Verhalten für Alarm Manager ist und dass ich die Aktion BOOT_COMPLETED verwenden sollte. Leider funktioniert es immer noch nicht. Hier ist, was ichSchwierigkeiten mit Android Alarm Manager, Boot abgeschlossen
Die main/Launcher Aktivität haben

int read;
while ((read = localDB.read(buffer)) > 0) {
newDB.write(buffer, 0 , read);

newDB.close();
