How to install and use ADB for Android devices on Windows, Mac, Linux, Android, Chromebooks, or even in a browser
If you want to do any number of things that require access to the so-called Android Debug Bridge (ADB) or the fastboot tools for Android — sideloading apps, installing custom ROMs, taking screenshots in apps that forbid it, or accessing certain hidden features — you'll need to get ADB up and running on your platform of choice first.
