Android Debug Bridge daemon
Android Debug Bridge (adb) is a versatile tool that lets you manage the state of an emulator instance or Android-powered device. It is a client-server program that includes three components: . A client, which runs on your development machine. You can invoke a client from a shell by issuing an adb command. Other Android tools such as the ADT plugin and DDMS also create adb clients. . A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device. . A daemon, which runs as a background process on each emulator or device instance. . This package provides the daemon component.
