1.1. Adb Introduction

• ADB full name Andorid Debug Bridge. Debug is a tool. adb tool is a standard C / S structure, which allows a computer simulator instance or Android device connected for communication. It provides convenient operations for a variety of devices, such as installation and debugging applications.
• Comprising the following parts:

　　1.Client end, running on the development machine, that your development PC. Adb used to send commands.

　　2.Daemon daemon running in commissioning equipment, namely commissioning phone or emulator.

　　3.Server end, as a background process running on a development machine, that your development PC. PC used to manage the communications between the Client terminal and mobile phones Daemon.

• Communication between the three: Client <-> Server <-> Daemon

1.2. Works

• When you start a adb client, the client first checks adb server process already running. If not, it starts the server process. When the server is started, it is bound to a local TCP port 5037 and listens for commands sent from adb client - all adb clients use port 5037 to communicate with the adb server.
