Question

通常,在我结束我的发言时,我向我的服务机构发出信号,在StartCommand使用一种真正的外衣安全关闭。我在任期申请表中这样做。我补充说,如果说的话,是因为我是在强行关闭这块地的 app子时获得一个完全的例外。

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null) {
        boolean state = intent.getBooleanExtra("terminate", false);
        mSafeShutdown = state;
    }
    else if (mUpdater != null && mUpdater.isRunning()) {
        Log.d(TAG, "activity force closed?" + 
            " Attempting to handle service thread shutdown safely...");
        mUpdater.isRunning(false);
        try {
            mUpdater.join();
        } catch (InterruptedException e) {
            Log.e(TAG,"Service s UpdaterThread couldn t join");
        }
    }
    return START_STICKY;
}

然而,这造成了我为活着提供的服务——

static final int DELAY = 2000;
public void run() {
    while (mIsRunning) {
        if (!mJobQueue.isEmpty()) {
            //do work
        }
        else if (mSafeShutdown) {
            mIsRunning = false;
            stopSelf();
        }
        else {
            sleep(DELAY);
        }
    }
}

部队关闭使这一局面脱节,难以确切了解正在发生什么。是否有更好的/宽松的办法告诉我,申请已经关闭?

since your thread is a child class, create a method in it to shut it down the thread and call it in your parent class.
