每2-3 min.My应用程序工作正常后，来此错误。

This error come after every 2-3 min.My application is working fine.

推荐答案

这是不是你的应用程序的问题。我猜你在哪里增加了对网络统计数据的支持（API> 12）一个模拟器测试应用程序。但是仿真器依赖于旧内核版本（2.6.x的），即不具有模块，以提供网络统计信息。因此，Android的网络统计服务无法打开文件的/ proc /净/ xt_qtaguid /统计其中，由内核模块收集的数据进行采集。因此，您获得这些奇怪的错误。

This is not the problem of your application. I guess that you test your application on a emulator where the support for network statistics was added (API > 12). But emulator relies on an old kernel version (2.6.x), that does not have a module to provide network statistics information. Thus, Android Network Statistics service cannot open file /proc/net/xt_qtaguid/stats where the statistics gathered by kernel module is collected. Therefore, you obtain these weird errors.
