Mastering Android: A Comprehensive Guide to ADB Commands

The Android Debug Bridge (ADB) is a command-line tool that enables advanced users and developers to interface with Android devices. ADB enables developers to run commands on Android devices, access system files, install and remove apps, and conduct a variety of other operations unavailable via the regular Android user interface.

To use ADB, you must have the Android SDK (Software Development Kit) installed on your computer. The Android SDK includes ADB, as well as other debugging tools and libraries needed for Android development. Once you have the SDK installed, you can access ADB by opening a command prompt or terminal window and navigating to the platform tools directory in the SDK.

Once you have ADB set up, you can run various commands on your Android device. Here are some of the handiest ADB commands you should be aware of:

adb devices

This command displays a list of every connected device that ADB has currently detected on your computer.

adb install [apk file]

The APK file (android application package) is installed on your device by this command.

adb uninstall [package name]

This command removes an application from your device, where the package name is the application’s package name.

adb shell

With the help of this command, you can perform commands and get direct access to system files on your device.

adb pull [source] [destination]

This command transfers a file or directory from the device to your computer, with the destination being the location on your computer where the file or directory will be copied to. The source is the file or directory on the device.

This command uses the dumpsys package command to display information about the specified package (app), where PACKAGE_NAME is the package name of the app you want to get information about, and then pipes the output to the grep command, which filters the output for lines that contain the word “permission”. This will display all the permissions that the app is currently using.

These commands allow you to interact with the device in various ways and retrieve valuable information, such as the currently running processes, network configuration, disk usage, and more, while performing mobile app automation testing.

However, if you are performing mobile app automation testing on a real device cloud like LambdaTest, you can leverage a set of ADB commands that can be executed within your app automation test scripts via JavaScript Executors.

To execute ADB commands on LambdaTest’s real device cloud, you need to use the following command with the specified parameters. Please note that the number of available ADB commands may be limited.

Looking to run app test automation scripts via JavaScript Executors? Head over to our documentation on ADB commands to get started on the LambdaTest platform.

In addition to supporting ADB commands, LambdaTest also provides a range of other mobile testing capabilities, including automated testing on real devices, device logs and video recordings, and more.

In short, ensuring that the application is free from errors before it is released to users is crucial, and debugging is a key part of this process for developers, engineers, and testers. Debugging is complementary to testing, which helps identify how errors have occurred in a program. To simplify the debugging process for testers, LambdaTest, a unified digital testing cloud, has released a new extension called LT Debug. With this tool, testers can debug more efficiently and with less hassle.

Conclusion

In conclusion, mastering ADB commands can greatly enhance your ability to work with Android devices, whether you’re a developer, a tester, or a power user. With ADB, you can interact with the device in various ways and retrieve valuable information, such as the currently running processes, network configuration, disk usage, and more.

In this article, I have covered a variety of ADB commands essential for working with Android devices. I have also provided examples and explanations for each command to help you better understand how they work and how to use them effectively.

Remember, ADB commands can be powerful tools, so use them with caution and ensure you know what you’re doing before you make any changes to your device. With practice and patience, you can become a master of ADB and unlock the full potential of your Android device.
