广播接收器的onReceive（）获取调用多次 [英] Broadcast receiver onReceive() getting called multiple times

问题描述

我有一个boot_completed接收器，大干快上的引导通知。

I have a boot_completed receiver which gets notified on boot.

    <receiver android:name=".BootCompletedReceiver">  
        <intent-filter>  
            <action android:name="android.intent.action.BOOT_COMPLETED" />  
        </intent-filter>  
    </receiver>

但它似乎被调用多次。我启动一个定时器，然后一服务，这导致多个定时器，然后该服务被重置并再次运行。

But it appears to get called multiple times. I start a timer, and then a service, which leads to multiple timers, and then the service gets reset and runs again.

创建计时器这样。这不是一个重复的计时器，它是：

Creating timer like this. This is not a repeating timer, is it?:

     private void setAlarm(Context context, long interval) {
        try {
            AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
            Intent intent = new Intent(RespondAlarmReceiver.ACTION_RESPOND_SMS);
            intent.putExtra("isChecking", true);
            PendingIntent alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

            int alarmType = AlarmManager.ELAPSED_REALTIME_WAKEUP;
            long triggerAtTime = SystemClock.elapsedRealtime() + interval; //interval is 60,000
            alarms.set(alarmType, triggerAtTime, alarmIntent);
        }
        catch (Exception e) {
            Log.e(DEBUG_TAG, "Unable to set alarm");
        }

作为一个方面说明，如果有人知道如何在Eclipse调试器附加到开机广播接收机或正在运行的服务，那将是非常美妙的。

As a side note, if anybody knows how to attach the Eclipse debugger to the Boot-up broadcast receiver or to a running service, that would be fantastic.

推荐答案

这是奇怪的是，你会得到多个定时器启动。尝试通过的 PendingIntent.FLAG_ONE_SHOT 作为内的最后一个参数的 PendingIntent.getBroadcast

It's strange that you'd be getting multiple timers started. Try passing PendingIntent.FLAG_ONE_SHOT as the last argument inside of PendingIntent.getBroadcast
