Android 获取手机整体流量使用情况以及某个应用的流量的统计

很多安全卫士类软件都实现了网速监测功能，也算是一个比较实用的功能。Android下，TrafficStats类实现了对流量的统计。

/proc/uid_stat/uid/tcp_send        上传流量
/proc/uid_stat/uid/tcp_rcv         下载流量

static long getMobileRxBytes()//获取通过Mobile连接收到的字节总数，但不包含WiFi   
static long getMobileRxPackets()//获取Mobile连接收到的数据包总数   
static long getMobileTxBytes()//Mobile发送的总字节数   
static long getMobileTxPackets()//Mobile发送的总数据包数   
static long getTotalRxBytes()//获取总的接受字节数，包含Mobile和WiFi等   
static long getTotalRxPackets()//总的接受数据包数，包含Mobile和WiFi等   
static long getTotalTxBytes()//总的发送字节数，包含Mobile和WiFi等   
static long getTotalTxPackets()//发送的总数据包数，包含Mobile和WiFi等   
static long getUidRxBytes(int uid)//获取某个网络UID的接受字节数   
static long getUidTxBytes(intuid) //获取某个网络UID的发送字节数  

获取某个应用的流量的统计（根据包名）

一、根据包名获取相应的UID；

/*** 获取当前应用uid* @return*/public int getUid() {try {PackageManager pm = mContext.getPackageManager();ApplicationInfo ai = pm.getApplicationInfo(mContext.getPackageName(), PackageManager.GET_ACTIVITIES);return ai.uid;} catch (NameNotFoundException e) {e.printStackTrace();}return -1;}

二、根据UID获取相应的流量的统计

TrafficInfo tr=new TrafficInfo(getApplicationContext());int uid=tr.getUid();Log.e("asdf",uid+"");Log.e("asdf",tr.getRcvTraffic()+"--"+tr.getSndTraffic()+"-----"+tr.getTrafficInfo());
