我從Activity
開始Service
,然後我將Activity綁定到它。 如果我嘗試強制關閉任務管理器中的應用程序,將調用Service onStartCommand()
方法,並調用NullPointerException。我不明白爲什麼onStartCommand()被調用。Android服務onStartCommand()在應用程序部隊關閉時觸發
該服務剛onStartCommand()重寫現在:
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Bundle bundle = intent.getExtras(); //This is line 24
//some stuff to get strings from bundle
return super.onStartCommand(intent, flags, startId);
}
例外:
