This article shows you the working principle and usage of ADB, a simple automation tool for Python programming, which is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Preface

ADB, the Chinese name Android Test Bridge, is a versatile command-line tool that can be used to perform various device operations (such as installing and debugging applications) and to provide access to Unix shell, which can be used to run various commands on the device. It is a client-server program that includes the following three components:

Client: used to send commands. The client runs on the development computer. You can invoke the client from the command line terminal by issuing the ADB command.

Daemon: runs commands on the device. The daemon runs as a background process on each device.

Server: manages communication between the client and the daemon. The server runs as a background process on the development machine.

With this command line tool, we can use it to manipulate the resources on the phone, and we can easily manipulate the applications on the phone without the help of Android SDK.

I. working principle

When you start an ADB client, the client first checks to see if any ADB server processes are running. If not, it starts the server process. After startup, the server binds to local TCP port 5037 and listens for commands issued by ADB clients-all ADB clients communicate with the ADB server through port 5037.

The server then establishes a connection with all running devices. It scans odd-numbered ports between 5555 and 5585, which are used by the first 16 simulators, to find the simulator. Once the server discovers the ADB daemon (ADBD), it establishes a connection with the appropriate port. Note that each emulator uses a pair of ports in order-an even-numbered port for console connections and an odd-numbered port for ADB connections.

Download ADB

Here the editor is ready for you. Download address: https://u062.com/file/7715018-452566390. If you want to use ADB in any file directory, you must add the environment variable to the installation directory of ADB. Then we can use ADB's interface tool, which can easily execute ADB commands and display the results. This tool is APKInstaller, download address: https://u062.com/file/7715018-452566398, as shown in the figure:

III. Basic operation

1. Start-up and shutdown operation of the device

Here I choose to connect to the simulator to see the difference between connections.

1)。 Connect the equipment

Adb connect 127.0.0.1 6200 connects to a simulator

2)。 Start the service

Adb start-server# enables the service.

3)。 View Devic

Adb devices # View device information adb version # device version adb help # help documentation adb get-state # View device status device (normal connection), offline (connection abnormal), unknown (no connection) adb get-serialno # get serial number adb get-devpath # get device path adb shell cat / system/build.prop # get device name

4)。 Operate multiple Devic

Adb-a listens on all network interfaces Not just localhost-d using USB devices (if multiple devices are incorrectly connected)-e using TCP / IP devices (if multiple TCP / IP devices are available)-s using the given serial number (overriding ANDROID_SERIAL)-t using the given device ID-h adb server hostname (default = localhost)-p adb server port (default = 5037)-l listening from sockets Adb server of (default = tcp: localhost: 5037) for example: adb-s 127.0.0.1 localhost 62001 shell

In this way, we have entered the Shell interface of the simulator.

5)。 Shut down the service

Adb kill-server

6)。 Set the port that listens to TCP/IP

Adb tcpip 5555

7)。 Disconnect

Adb disconnect 127.0.0.1:62001

8)。 Shutdown and restart

Adb reboot # device restart adb shutdown # device shutdown

9) .Root permissions

Adb root # normal output: restarting adbd as root adb unroot # cancels root permission

10)。 Brushing mode

Adb reboot bootloader # reboots to bootloader, that is, the brush mode adb reboot recovery # restarts to recovery, that is, the recovery mode adb sideload # updates the system

11)。 Command reprint

Adb wait-for-device # reprints the command in the adb command before the simulator / device is connected. Equipment application operation

1)。 View application

Adb shell pm list packages # all applications adb shell pm list package-f # adb shell pm list packages-s # system Application adb shell pm list packages-3 # tripartite Application adb shell pm list packages | findstr bluetooth # filter application pipe character to search, use grep under Linux

2)。 View the Activity information of the application

Adb shell dumpsys package com.android.bluetooth # View the package name information of the system application Bluetooth adb shell dumpsys activity activities # View all active package names adb shell dumpsys activity | findstr mFocusedActivity # see which package adb shell dumpsys activity top is currently restarted | findstr activity # find the parent window of the device active program

3)。 Clear application data and cache

Adb shell pm clear

3. Install uninstall application adb install D:/aa.apk# install apk adb install-r D:/aa.apk# override install retain data and cache files-g grants all runtime permissions adb shell pm install / scard/picture# the apk adb uninstall-k package name installed on the phone requires-s to specify 4 in the simulator or real machine. Log adb logcat# View log adb logcat-v time # print details log, all current operations and results will be recorded, and continuous monitoring by default Press Ctrl+c to end adb logcat-v time > D:\ log.txt # Save log to computer adb logcat-f / sdcard/1.txt # Save log to mobile phone adb logcat | findstr com.android.bluetooth # Save log with specified package name adb logcat-c # clear log output adb logcat | findstr ActivityManager # View currently running Activity adb logcat | findstr Displayed # View currently running Activity adb bugreport # View the bug report adb logcat-b radio # wireless communication log adb shell dmesg # kernel log 5. Device file operation # transfer the files on the computer to the mobile memory card adb push C:\ Users\ Administrator\ Desktop\ 1.gif / sdcard/ # transfer the files in the mobile storage card to the computer adb pull / sdcard/1.gif C:\ Users\ Administrator\ Desktop\

6. Screenshot, screenshot adb shell screencap / sdcard/1.png # current window screenshot save to mobile phone adb shell / system/bin/screencap-p / sdcard/2.png adb exec-out screencap-p > 1.png # screenshot save to computer adb shell screenrecord > 1.mp4 # screen recording Ctrl+c stops recording-- size # video size-- bit-rate # bitrate-- time-limit # duration-- verbose # command line displays log information Note: screencap 7.Shell is not supported in simulator and Android versions below

There are many commands in Shell, let's briefly list:

The above is the whole content of ADB, through the understanding of ADB, I believe you should be able to program through Python to do a simple version of the automation tool, no longer rely on Airtest.
