Android Debug Bridge adb is a versatile command-line tool that lets you communicate with a device. The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.

It is a client-server program that includes three components:. For information on connecting a device for use over ADB, including how to use the Connection Assistant to troubleshoot common problems, see Run apps on a hardware device. When you start an adb client, the client first checks whether there is an adb server process already running.

If there isn't, it starts the server process. When the server starts, it binds to local TCP port and listens for commands sent from adb clients—all adb clients use port to communicate with the adb server.

The server then sets up connections to all running devices. It locates emulators by scanning odd-numbered ports in the range tothe range used by the first 16 emulators.

Where the server finds an adb daemon adbdit sets up a connection to that port. Note that each emulator uses a pair of sequential ports — an even-numbered port for console connections and an odd-numbered port for adb connections. For example:. Emulator 1, console: Emulator 1, adb: Emulator 2, console: Emulator 2, adb: and so on As shown, the emulator connected to adb on port is the same as the emulator whose console listens on port Once the server has set up connections to all devices, you can use adb commands to access those devices.
