Implementation method of Android executing shell script in linux terminal to directly print the log of currently running app

1. Problems

Most of the time, we need to print the log of currently running app on ubuntu terminal. Our common practice is

1), get the package name

Open the currently running app, and then type the following command, and then you can see the package name after TASK in line 1

adb shell dumpsys activity top

2) The pidcat. py script is installed on our terminal, and then the full log of app currently running can be printed by executing the following command.

pidcat.py packageName

3) Think, why do you need this repeated operation every time? 1 When it comes to repetition, we should immediately think about whether we can solve repetitive operation with scripts

2. Solutions

Get the package name by executing the script file, and then execute the pidcat.py packageName Command

3. Code implementation

1) Create a new pcat file

#!/bin/bash
dev="device"
devices=$(adb devices)
if [[ ${devices} == *$dev ]]
then
  echo " The mobile phone has been connected to the terminal "
  info=$(adb shell dumpsys activity top | awk -F " " '/TASK/ {print $2}')
  echo " Current running app The package name of is :${info}"
  pidcat.py --hw ${info}
else
 echo " The mobile phone is not connected to the terminal "
fi

2) Copy the pcat file to the following directory

/usr/local/bin/

4. Test results

1) Open the app of the mobile phone "Game Center"

2) Enter pcat at the terminal

3) Operation result of that terminal

*****~$ pcat 
 The mobile phone has been connected to the terminal 
 Current running app The package name of is :com.huawei.gamebox
         Zygote D CtrlSocket libc.so ctrl_sockets_set_addr pfunc is not exist!
              Process com.huawei.gamebox created for activity com.huawei.gamebox/.GameBoxActivity
              PID: 29758  UID:  GIDs: 
     ActivityThread D ActivityThread,attachApplication
         HwCust D Create obj success use class android.content.res.HwCustHwResourcesImpl
     AnalyticUtils D experience = 1
    StoreApplication D create application.
    HwPolicyFactory V : success to get AllImpl object and return....
    HwWidgetFactory V : successes to get AllImpl object and return....
     ActivityThread V ActivityThread,callActivityOnCreate

5. Summary

Repeated operations we can use scripts to solve problems and improve development efficiency. Remember to make sure your terminal can run pidcat before using this
