Using ADB and fastboot

What is adb?

The Android Debug Bridge (adb) is a development tool that facilitates communication between an Android device and a personal computer. This communication is most often done over a USB cable, but Wi-Fi connections are also supported.

adb is like a “Swiss-army knife” of Android development. It provides numerous functions that are described in detail by the command adb --help. Some of the more commonly used commands are listed in the “popular adb commands” section below.
