我想在應用程序安裝到設備上後立即啓動的服務中註冊兩個廣播接收器。如果設備重新啓動（在引導完成的接收器上使用），此服務也會啓動。廣播接收器不能使用服務
該服務啓動一個活動，其中觸發所有UI更改和通知。廣播接收器在服務內部正常工作，直到應用處於前景或背景狀態。但是，如果我殺了應用程序。接收者似乎沒有迴應。
這是代碼爲我服務
public class StartupService extends Service {
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate(){
super.onCreate();
Log.i("Easy Charger Service","Service Started");
this.registerReceiver(ChargerPluggedInReceiver, new IntentFilter(Intent.ACTION_POWER_CONNECTED));
this.registerReceiver(ChargerPluggedOutReceiver, new IntentFilter(Intent.ACTION_POWER_DISCONNECTED));
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i("EASYCHARGER", "Service is Running");
return super.onStartCommand(intent,flags,startId);
}
public BroadcastReceiver ChargerPluggedInReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(StartupService.this, "Charger Plugged", Toast.LENGTH_LONG).show();
Intent startup_intent = new Intent(StartupService.this,Home.class);
startup_intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startup_intent);
}
};
public BroadcastReceiver ChargerPluggedOutReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.i("EASYCHARGER", "ChargerPluggedOut");
if(intent.getAction().equalsIgnoreCase(Intent.ACTION_POWER_DISCONNECTED)){
Log.i("EASYCHARGER", "ChargerPluggedOut - Performing Action Now");
//unregisterReceiver(batteryLevelReceiver);
Toast.makeText(StartupService.this, "Charger Unplugged", Toast.LENGTH_LONG).show();
}
}
};
}
這是我的活動課

很明顯，如果你殺了應用程序，你停止了服務本身。因此，您的接收器將不會收到任何內容，因爲該服務不再存在。 –
當應用程序安裝它第一次啓動時，我開始我的服務，讓接收器註冊。現在，即使應用程序停止，服務如何被破壞，接收器也如何？ –
