  • Navigate to the folder where you extracted the ADB platform tools.
  • Type adb shell and press Enter.

You should now see a prompt that looks like shell@android:/ $. This is the ADB shell prompt, where you can execute commands to interact with your Android device.

Navigating the File System

One of the most common tasks you’ll perform in ADB shell is navigating the file system. Here are some basic commands to get you started:

  • cd: Change directory. For example, cd /sdcard will take you to the root of your device’s SD card.
  • ls: List files and directories. For example, ls /sdcard will list the files and directories on your SD card.
  • pwd: Print working directory. This command will show you the current directory you’re in.

Executing Commands

ADB shell allows you to execute commands to perform various tasks on your device. Here are some examples:

  • pm list packages: List all installed packages on your device.
  • dumpsys: Display system information, such as the current activity stack.
  • screencap: Capture a screenshot of your device’s screen and save it to a file.

Editing Files

ADB shell also allows you to edit files on your device using the echo command. For example, to add a new line to a file, you can use the following command:

echo "new line" >> /sdcard/example.txt

This will add the text “new line” to the end of the file example.txt on your SD card.

Tips and Tricks

Here are some additional tips and tricks to help you get the most out of ADB shell:

Using ADB Shell with Root Privileges

If you have a rooted device, you can use ADB shell with root privileges to perform tasks that require elevated access. To do this, type adb root before launching ADB shell.

Using ADB Shell over Wi-Fi

By default, ADB shell connects to your device over USB. However, you can also use ADB shell over Wi-Fi using the following command:

adb tcpip 5555

This will enable ADB over Wi-Fi on port 5555. You can then connect to your device using adb connect <IP address>:5555.

Using ADB Shell to Automate Tasks

ADB shell can be used to automate tasks on your device using scripts. You can create a script that executes a series of commands and then run it using ADB shell.

Command Description
adb shell Launches ADB shell
cd Changes directory
ls
pwd Prints working directory
pm list packages Lists all installed packages
dumpsys Displays system information
screencap Captures a screenshot of the device’s screen

In conclusion, ADB shell is a powerful tool that allows developers and power users to interact with their Android devices in a variety of ways. By following the steps outlined in this article, you can set up ADB on your computer, enable USB debugging on your device, and use ADB shell in a terminal emulator to execute commands, navigate the file system, and even automate tasks. Whether you’re a seasoned developer or a curious power user, ADB shell is an essential tool to have in your toolkit.
