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：

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：

8、又找到个报错service：

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
