原由：项目中有人写了个位置上传的服务，其实一直没问题，后来不知道什么时候出现了很多抱怨，是开着app流量一下子跑掉了几个G，差点就要卖房子还移动话费了，很多同事哭笑不得的找上门来，后来PM解决了，我一直没时间弄明白，今天终于还原了这个大Bug，解决后才发现，要细心那，很多问题有可能测试都测不出来的，好的产品真是不容易啊，从产品到开发到测试都需要慎之又慎。我还差得远，积累吧。
解决问题的过程就是不断百度的过程啊。还是先贴几个总结的比较好的Blog吧。
1. eclipse的输出不够用的，利用adb logcat的命令输出到文件。
adb logcat -f > D:\log.txt
adb logcat TAG:D *:S -f > D:\log.txt
-f 不好用的话试试-d。要好好设置过滤，否则出来一堆没用的log，我的有时候会不成功，还是Ubunt下的grep好用。
2. DDMS的Thread查看：说实话，信息太少，我没怎么用到
3.异常信息
