The ADB cheatsheet provides a general list of basic commands for Android operating system and applications. Please note that certain commands require the device to be rooted, furthermore certain Android versions may require a tweak to the commands.

Device Commands

Android ADB Device commands are commands that you can use to control the Android device over USB from a computer. You can use them to list all devices, restart server and reboot!

  • adb devices - List all connected devices.

Warning: Shell commands can brick your operating system, so make sure to double check them before running.

ADB shell is a command-line interface that you can use to access the shell and run various commands on your Android device. You can use ADB shell commands to perform actions such as changing the resolution of your device display, uninstalling bloatware or system apps, enabling and disabling features, modifying the system files, ect..

Remember to keep a backup of the commands that you run via shell, I recommend creating a log.txt file and output all the commands to that file.
