How to use ADB shell to query process traffic

1、 Get applied Pid.

       Can pass adb shell ps Get all process information , Of course, it contains the application pid And the package name . Then search the returned information （ Find by package name ）.

C:\Users>adb shell ps
USER      PID   PPID  VSIZE  RSS   WCHAN              PC  NAME
root      1     0     17336  1668  SyS_epoll_ 0000000000 S /init

root      3     2     0      0     smpboot_th 0000000000 S ksoftirqd/0
root      5     2     0      0     worker_thr 0000000000 S kworker/0:0H

root      20    2     0      0     worker_thr 0000000000 S kworker/1:0H
root      21    2     0      0     rcu_nocb_k 0000000000 S rcuop/1
root      22    2     0      0     rcu_nocb_k 0000000000 S rcuos/1

Are the screenshots above still captured ; Find the one you signed up for PID, Use... In the back

2、 Get applied Uid.

      Android System catalog file /proc/pid/status（ Be careful ： Marked red pid It's No 1 What we got in step pid, Is a greater than 0 The number of ） Contains information about uid Information about . With pid=15904 For example , adopt adb shell cat /proc/15904/status You can get the following information ：

C:\Users>adb shell
msm8953_64:/ $ cat /proc/15904/status
cat /proc/15904/status
Name:   com.******
State:  S (sleeping)
Tgid:   15904

      By analyzing the above information, you can get Uid.

3、 Read flow value .

      Android System catalog file /proc/uid_stat/uid/ There are usually two files under the tcp_snd and tcp_rcv.（ Be careful ： Marked red uid Is obtained in step 2 Uid The number ）. adopt adb shell cat /proc/uid_stat/10092/tcp_snd and adb shell cat /proc/uid_stat/10092/tcp_rcv You can obtain uplink traffic and downlink traffic respectively .

127|msm8953_64:/ $ ls /proc/uid_stat/10092
ls /proc/uid_stat/10092
tcp_rcv tcp_snd

msm8953_64:/ $ cat /proc/uid_stat/10092/tcp_snd
cat /proc/uid_stat/10092/tcp_snd
119973585

msm8953_64:/ $ cat /proc/uid_stat/10092/tcp_snd
cat /proc/uid_stat/10092/tcp_rcv

We will provide the following information adb Some commands for ：

    adb devices                          List all devices 
    adb -s  Equipment name  shell                 Enter the corresponding equipment 
    cd proc                              Enter the attribute directory of the device 
    cd uid_stat                          Get into  user id  Status directory , When each application is installed, the system will assign a corresponding... To each application  uid
    ls                                   List  uid_stat  Corresponding to all applications in the directory  user id  Catalog 
    cd uid                               Enter the corresponding application  uid  Catalog 
    ls                                   View correspondence  uid  In the catalog  tcp_rcv  and  tcp_snd  Catalog 
    cat tcp_rcv                          View the data information received by the application 
    cat tcp_snd                          View the data information sent by the application 

Reprint it later Analysis of other great gods tcp_send Code ：

    private Long getTotalBytesManual(int localUid) {
//        Log.e("BytesManual*****", "localUid:" + localUid);
        File dir = new File("/proc/uid_stat/");
        String[] children = dir.list();
        StringBuffer stringBuffer = new StringBuffer();
        for (int i = 0; i < children.length; i++) {
            stringBuffer.append(children[i]);
            stringBuffer.append("   ");
        }
//        Log.e("children*****", children.length + "");
//        Log.e("children22*****", stringBuffer.toString());
        if (!Arrays.asList(children).contains(String.valueOf(localUid))) {
            return 0L;
        }
        File uidFileDir = new File("/proc/uid_stat/" + String.valueOf(localUid));
        File uidActualFileReceived = new File(uidFileDir, "tcp_rcv");
        File uidActualFileSent = new File(uidFileDir, "tcp_snd");
        String textReceived = "0";
        String textSent = "0";
        try {
            BufferedReader brReceived = new BufferedReader(new FileReader(uidActualFileReceived));
            BufferedReader brSent = new BufferedReader(new FileReader(uidActualFileSent));
            String receivedLine;
            String sentLine;

            if ((receivedLine = brReceived.readLine()) != null) {
                textReceived = receivedLine;
//                Log.e("receivedLine*****", "receivedLine:" + receivedLine);
            }
            if ((sentLine = brSent.readLine()) != null) {
                textSent = sentLine;
//                Log.e("sentLine*****", "sentLine:" + sentLine);
            }
        } catch (IOException e) {
            e.printStackTrace();
//            Log.e("IOException*****", e.toString());
        }
//        Log.e("BytesManualEnd*****", "localUid:" + localUid);
        return Long.valueOf(textReceived).longValue() + Long.valueOf(textSent).longValue();
    }

Please point out what the gods have done wrong , thank you
