小白马卫士项目总结之流量统计

流量统计模块

核心代码：

<p>int uid=info.applicationInfo.uid;
 long trafficRx=TrafficStats.getUidRxBytes(uid);  //uid进程的总的接收量
  long  trafficTx=TrafficStats.long totalTrx=TrafficStats.getTotalRxBytes();   //手机上的总的流量包括手机流量与wifi流量
  long totalTtx=TrafficStats.getTotalTxBytes();
  
  long mobileRx=TrafficStats.getMobileRxBytes();  //手机上网的流</p><p> </p><p>量
  long mobileTx=TrafficStats.getMobileTxBytes();getUidTxBytes(uid);  //uid进程的总的发送量</p><p>*********************************************************************************</p><p> </p><p> </p><p>全部的代码：</p><p> </p><p>package cn.cbd.mobilesafe.activity.engine;</p><p>import java.util.ArrayList;

补充一下！ 在贴代码的时候，不知道怎么的！ 代码分开贴的话，就贴在一起了，不知道怎么回事儿！ 所以只好把核心代码与整个模块的代码贴在一起了！ 而且里面还出现了一些莫名其妙的xml标签！ 难道是论坛出现bug了吗
