android Service ANR 问题

service也是跑在UI Thread里的，只是比activity报ANR的阀值要大些，记得应该是>15秒报ANR，如果需要耗时的操作，还是应该放到子线程里完成。

PollingService 里面开启一个线程处理网络数据，不要用ipc bindService的方式，用广播通知数据更新。

下面是Service的代码，启动我调用actionStartPing，进入聊天页面，调用actionChatStartPing，调整请求平率为5秒一次，但不知道为什么会出现ANR问题
public class PollingService extends Service {

    public static final String ACTION = "com.ysxj.RenHeDao.Service.PollingService";

    private Notification mNotification;
    private NotificationManager mManager;

    private static int IsCON_TIMEOUT = 0;
private static final int CON_TIMEOUT = 60*1000;//无网络状态重试
private static final int ALIVE_INTERVAL=60*1000;//正常心跳
private static final int ALIVE_CHATINTERVAL=5*1000;//聊天页面心跳

private static int KEEP_ALIVE_INTERVAL=ALIVE_INTERVAL;

private static boolean isBroadcast=false;

private static String updatetime="";
private SysMessageListDao sListDao;
private ChatMessageListDao cListDao;
private String TAG="PollingService";

public static String MQTT_CLIENT_ID = "RenHeDao"; // These are the actions for the service (name are descriptive enough)
private static final String ACTION_START = MQTT_CLIENT_ID + ".START";
private static final String ACTION_STOP = MQTT_CLIENT_ID + ".STOP";
private static final String ACTION_KEEPALIVE = MQTT_CLIENT_ID + ".KEEP_ALIVE";
private static final String ACTION_RECONNECT = MQTT_CLIENT_ID + ".RECONNECT";
private static final String ACTION_SEND = MQTT_CLIENT_ID + ".SEND";
private static final String ACTION_WAITFORNETWORK = MQTT_CLIENT_ID + ".WAIT_FOR_NETWORK";
public static  final String    ACTION_STARTKEEPALIVE=MQTT_CLIENT_ID + ".STARTKEEPALIVES";
public static  final String    ACTION_CHATSTARTKEEPALIVE=MQTT_CLIENT_ID + ".CHATSTARTKEEPALIVES"; private Handler handler;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
// 发送心跳信息
public static void actionStartPing(Context ctx) {
isBroadcast=false;
Intent i = new Intent(ctx, PollingService.class);
i.setAction(ACTION_STARTKEEPALIVE);
ctx.startService(i);
}
// 聊天页面发送心跳信息
public static void actionChatStartPing(Context ctx) {
    isBroadcast=true;
Intent i = new Intent(ctx, PollingService.class);
i.setAction(ACTION_CHATSTARTKEEPALIVE);
ctx.startService(i);
}

    @Override
    public void onCreate() {       Logger.v(TAG, "MyQurData===onCreate=====!");
    }


    @Override
    public void onStart(Intent intent, int startId) {
       sListDao=new SysMessageListDao(PollingService.this);
         cListDao=new ChatMessageListDao(PollingService.this);
     Logger.v(TAG, "MyQurData===onStart=====!"+DateHelp.NowTime());    }


  //启动服务接收信息
   @Override
   public int onStartCommand(Intent intent, int flags, int startId)
   {
   if (intent.getAction().equals(ACTION_STOP) == true) { //停止服务
   this.stopSelf(0);
       }else if (intent.getAction().equals(ACTION_WAITFORNETWORK) == true) { //等待网络

       }else if (intent.getAction().equals(ACTION_STARTKEEPALIVE) == true) { //启动定时心跳信息
         KEEP_ALIVE_INTERVAL=ALIVE_INTERVAL;
          stopKeepAlives();
         startKeepAlives();
       } else if (intent.getAction().equals(ACTION_KEEPALIVE) == true) { //发送心跳信息
keepAlive();

   }else if(intent.getAction().equals(ACTION_CHATSTARTKEEPALIVE) == true)
       {
        KEEP_ALIVE_INTERVAL=ALIVE_CHATINTERVAL;
        stopKeepAlives();
        startKeepAlives();
       }
   return startId;
      } private synchronized void keepAlive() {
Logger.v(TAG, "keepAlive=====!"+DateHelp.NowTime());
MyQurData(MyApplication.getInstance().getUpdatetime());

  }// Schedule application level keep-alives using the AlarmManager设置定时发送心跳信息
private synchronized void startKeepAlives() {
Logger.v(TAG, "MyQurData===startKeepAlives=====!"+DateHelp.NowTime()); Intent  i = new Intent();
i.setClass(this, PollingService.class);
i.setAction(ACTION_KEEPALIVE);
//startService(i);
long triggerAtTime = SystemClock.elapsedRealtime();
PendingIntent pi = PendingIntent.getService(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmMgr.setRepeating(AlarmManager.ELAPSED_REALTIME,triggerAtTime+KEEP_ALIVE_INTERVAL,KEEP_ALIVE_INTERVAL, pi);
}


//停止轮询服务
private synchronized void stopKeepAlives() {

Intent  i = new Intent();
i.setClass(this, PollingService.class);
i.setAction(ACTION_KEEPALIVE);
//startService(i);
long triggerAtTime = SystemClock.elapsedRealtime();
PendingIntent pi = PendingIntent.getService(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        //取消正在执行的服务
alarmMgr.cancel(pi);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        System.out.println("Service:onDestroy");
    }
    private void MyQurData(String updatetime){
     AsyncHttpRestClient.get(ChatAPI.DynamicNewsListURL(updatetime), jHandler);
    }

我已经自己解决了，问题出在onStartCommand方法中
