android - 调用 stopForeground 导致重启当前服务

Question

我使用通知 ID 启动了一个前台服务，但是当我尝试调用 stopForeground(false) 时，该服务正在重新启动。但根据 android 文档，调用此方法不会停止服务。

@Override
    public void onCreate() {
      LogHelper.d(TAG, "onCreate");
        super.onCreate();
        initMediaSeesion();
    }

@Override
    public int onStartCommand(Intent startIntent, int flags, int startId) {
        LogHelper.d(TAG, "onStartCommand");
        MediaButtonReceiver.handleIntent(mSession, startIntent);
        return START_STICKY;
    }

    public void startNotification() {
            if (!mStarted) {
                Notification notification = createNotification();
                if (notification != null) {
                    mService.startForeground(NOTIFICATION_ID, notification);
                    mStarted = true;
                }
            }
        }

    @Override
        public void pause() {
            LogHelper.d(TAG, "Calling stopForeground false");
            giveUpAudioFocus();
            mService.stopForeground(false);
    }

因为您在停止服务时设置了 START_STICKY，它会自动重新启动。

这是 Android DOC 所说的

For started services, there are two additional major modes of operation they can decide to run in, depending on the value they return from onStartCommand(): START_STICKY is used for services that are explicitly started and stopped as needed, while START_NOT_STICKY or START_REDELIVER_INTENT are used for services that should only remain running while processing any commands sent to them. See the linked documentation for more detail on the semantics.

尝试使用 stopSelf();
