Android Debug Bridge (ADB) Utility

Android Debug Bridge (adb) is a versatile command-line tool that lets me communicate with a device. The adb command facilitates a variety of device actions, such as installing and debugging apps. adb provides access to a Unix shell that I can use to run a variety of commands on a device. It is a client-server program that includes three components:

A client, which sends commands. The client runs on your development machine. You can invoke a client from a command-line terminal by issuing an adb command.
A daemon (adbd), which runs commands on a device. The daemon runs as a background process on each device.
A server, which manages communication between the client and the daemon. The server runs as a background process on your development machine.

adb is included in the Android SDK Platform Tools package.
