1、这几天总是出现用户无响应的问题，查日志，有个报错信息：

2、一看就是融云的reconnectService在后台给我整崩了，干他，屏蔽。

3、还报错，找报错信息：

4、信鸽的后台service咋也有问题，暂时都先屏蔽掉。

5、还(zhen)有(shi)问(fu)题(le)

6、这回后台不报错了，只能去/data/log下面看日志了，有个dumpstate_app_anr.txt的文件，上里面瞅瞅，还看到了另外一个出错信息：

05-27 11:01:19.684  1079  1500 I am_anr  : [0,15000,com.***.hxm,16301638,Executing service com.***.hxm/com.***.B_ApplicationClass.HXMMobileStudyService]
7、这里有什么阻碍线程的操作么，费解

8、又找到个报错service：

9、这是个定时发送tcp消息的service，顿时灵感来了，是不是发送tcp消息的时候堵住了，导致了service无响应，而且

HXMMobileStudyService中有链接tcp逻辑的代码，所以anr错误提示中也会有这个service的报错信息

10、service中处理逻辑也是在主线程中，所以service堵了也相当于主线程堵了。

11、把所有链接tcp代码和发送tcp代码，都放到线程池中加载

12、问题解决！！！融云和信鸽不知道什么鬼，service里怎么各种anr
