我是靠谱客的博主笑点低大神，最近开发中收集的这篇文章主要介绍超简单心跳包，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

一、先新建一个发送心跳的广播

public class MainActivity extends Activity {

private Timer mTimer;
private int timejumping = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  mTimer = new Timer();
  mTimer.schedule(new TimerTask() {
   @Override
   public void run() {
    Intent localIntent = new Intent();
    localIntent.setAction("android.intent.action.rousecourse.controlstate");
    sendBroadcast(localIntent);
    Log.e("MainAcetivity", "发送一条广播");
    if (timejumping >= 10) {
     timejumping = 0;
     // 加心跳包
    } else {
     timejumping++;
    }
   }
  }, 0, 3 * 1000);
  Log.e("schedule", "是否执行了");
}

}

二、把接收器APP设置为开机启动

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  Log.i("MainActivity", "service");
  Intent localIntent = new Intent(this, MyService.class);
  startService(localIntent);
  finish();

}

}
接收后打印日志

public class MyService extends Service {

@Override
public void onCreate() {
  // TODO Auto-generated method stub
  super.onCreate();
  Log.i("MyService", "启动了");
  LocalReceiver localReceiver = new LocalReceiver();
  IntentFilter intentFilter = new IntentFilter();
  intentFilter.addAction("android.intent.action.rousecourse.controlstate");
  registerReceiver(localReceiver, intentFilter);

}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
public class LocalReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
   // TODO Auto-generated method stub
   if (intent.getAction().equals("android.intent.action.rousecourse.controlstate")) {
    Log.i("LocalReceiver", "收到广播");
   }

  }
}

}
