环信Android SDK2.2.5 1月27号出现重复下载server.xml直到StackOverflowError的现象
今天抓到部分这样的崩溃, 测试部分未崩溃手机也出现了重复下载的现象, 应该是和网络环境也有一定的关系
重复下载的URL是http://www.easemob.com/easemob/server.xml?sdk_version=2.2.5&app_key=***&file_version= ，伴随着这么一条LOG
一个典型的堆栈是这样的

这个是在我们app上复现的log,testin上自动测试出来的结果。
分析原因是 取dns config时， 上级dns server，没有正确识别域名http://www.easemob.com/......
识别成一个错误的地址127.0.0.1:9280， 同时由于SDK的递归取dns，现在增加了一个hotfix，如果取的此时比较多，就不递归取了，避免stackoverflow.
春节后发2.2.6时，会采用一个新的策略，直接连IP， 而不是通过域名，避免DNS错误。
如果需要紧急的hotfix，请跟qq:2703226757 联系
