[Android Traffic] Android traffic calculation method

About Android Traffic

• Traffic statistics File: path/proc/net/dev

Open the file, where Lo is the local traffic, Rmnet0 is 3G/2G traffic, Wlan0 is wireless traffic.

• You can find a directory of related categories, such as Rmnet0, under/sys/class/net/. Statistics downstream rx_bytes and Tx_bytes records send and receive traffic in their subdirectories.
• In/PROC/UID_STAT/{UID}/TCP_RCV record the UID app download traffic bytes,/proc/uid_stat/{uid}/tcp_snd have the Uid app upload traffic bytes

Trafficstats Learning

• Trafficstats Google Develop documentation
• Trafficstats source File View
• Important API:

Static long  getmobilerxbytes ()   //Gets the total number of bytes received through the mobile connection and does not contain wifi  
Static Long   getmobilerxpackets ()   //Gets the total number of packets received by the mobile connection   
Static long   Getmobiletxbytes ()   //mobile The total number of bytes sent   
Static long  getmobiletxpackets ()    //mobile the total number of packets sent   
Static long  gettotalrxbytes ()   //Gets the total number of accepted bytes, Includes mobile and WiFi   ,
Static long  gettotalrxpackets ()   //total number of accepted packets, including mobile and WiFi, etc.   
Static long  gettotaltxbytes ()   //The total number of bytes sent, including mobile and WiFi   
Static long  gettotaltxpackets ()   //The total number of packets sent, including mobile and WiFi    
Static long   getuidrxbytes (int uid)   //Gets the number of accepted bytes for a network UID   
Static long  getuidtxbytes ( int uid)//Gets the number of bytes sent for a network UID [/mw_shl_code]
Note: The Trafficstats class appears after the Android 2.2 API level (8).

When doing GXB, the method of checking traffic is based on the UID query system file:

/proc/uid_stat/uid/tcp_send Upload Traffic
/PROC/UID_STAT/UID/TCP_RCV Download Traffic

When doing AVT, it is the method of calling the system through the UID to query the traffic:

proc/uid_stat/10086
Long tx = Trafficstats.getuidtxbytes (UID);//upload traffic sent by byte
Long rx = trafficstats.getuidrxbytes (UID);//Download Traffic byte

Trafficstats.getmobiletxbytes ();//Get the total traffic of mobile 3g/2g network uploads
Trafficstats.getmobilerxbytes ();//Mobile 2g/3g Total Download traffic

Trafficstats.gettotaltxbytes ();//Mobile phone all network interface including WIFI,3G, 2g upload Total traffic
Trafficstats.gettotalrxbytes ();//Mobile all network interface including WIFI,3G, 2g download Total traffic

The essence is the same.
