这里简单介绍两种实现心跳的方式。

**第一种，简单粗暴线程实现**

new Thread(new Runnable() {
                    @Override
                    public void run() {
                        while (true) {
                            try {
                                Thread.sleep(heartTime);
                            } catch (InterruptedException e) {
    //                            e.printStackTrace();
                            }
                            //业务逻辑
                        }
                    }
                }).start();

**第二种，闹钟+广播**

@Override
        public int onStartCommand(Intent intent, int flags, int startId) {
    
            if (count != 0) {
                heartReq();
            } else {
                postReceiver("监听服务启动，开启心跳");
            }
            count++;
            postReceiver("心跳次数："+count);
            postReceiver("心跳间隔时间："+(heartTime/1000) +"秒");
            Global.debug("心跳次数====="+count+"======");
            long triggerAtTime = SystemClock.elapsedRealtime() + heartTime;
            Intent i = new Intent(this, HeartReceiver.class);
            mPi = PendingIntent.getBroadcast(this, 0, i, 0);
    //        mManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerAtTime, mPi);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    mManager.setExactAndAllowWhileIdle(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerAtTime, mPi);
                } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    mManager.setExact(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerAtTime, mPi);
                } else {
                    mManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerAtTime, mPi);
                }
    
    
            return START_STICKY;
        }

广播：

public class HeartReceiver extends BroadcastReceiver {
    
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
    
            Global.debug("心跳广播接收=====");
            Intent intent2 = new Intent(context, ListenService.class);
            context.startService(intent2);
    
        }
    
    }
