发现流量统计主流上有两种方式
1.使用系统统计类TrafficStats获取
A. 缺少获取某个app接受和发送的2G/3G/4G流量,不包含wifi，这些API无法满足该需求。
2.通过系统文件解析读取
A. /proc/net/xt_qtaguid/iface_stat_fmt：该文件中已经按照类型统计出了不同类型网络数据的总数，因此获取当前设备的总接受字节数等设备级统计信息，直接分析该文件，能最快获取结果
B. /proc/net/xt_qtaguid/stats：该文件中则是按照uid进行了分类，适合于做更细力度（应用级/线程级）的分析
C. 缺点 Android9.0已经不支持了；
当前我们采用TrafficStats方式
一、TrafficStats方法介绍
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
static long getUidTxBytes(int uid) //获取某个网络UID的发送字节数
二、解决获取某个app接受和发送的2G/3G/4G流量,不包含wifi
方案：
通过判断当前网络处于2G/3G/4G/wifi来记录；
判断2G/3G/4G网络
相关类ConnectivityManager 、 NetworkInfo 、TelephonyManager
int networkType = NetworkInfo .getSubtype()；
TelephonyManager.getNetworkClass(int networkType) ;
由于 TelephonyManager部分方法和常量是隐藏，需要我们自己去更加该类处理

* @return
*/
public static int getMoblieNetWorkType(Context context) {
if (context != null) {
ConnectivityManager mConnectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mMobileNetworkInfo = mConnectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (mMobileNetworkInfo != null && mMobileNetworkInfo.isConnected()) {
return getNetworkClass(mMobileNetworkInfo.getSubtype());
}
}
return VideoConstants.NETWORK_CLASS.NETWORK_CLASS_UNKNOWN;
}
/**
