2.3开始android就提供来这个类的API，这样我们就可以方便的用他来实现统计手机流量来。这个类其实也很简单，贴上他的几个方法，大家一看就知道怎么用了。
static long getMobileRxBytes() //获取通过Mobile连接收到的字节总数，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，某一个进程的总接收量
static long getUidTxBytes(int uid) //获取某个网络UID的发送字节数，某一个进程的总发送量
