　　Android Debug Bridge

AndroidDebug the bridgeAdbIs a universal tool used to manage the status of simulators or real machines.-The server model consists of three parts:

*The client is running on a development computer and can be run in the command line.AdbCommand to call the client, suchADBPlug-ins andDDMSSuchAndroidTools can also be calledAdbClient.

*The server is a background process running on a development computer. It is used to manage the communication between a client and a daemon running on a simulator or a real machine.

*The daemon part runs on the background of the simulator or mobile phone.

　　When startedAdbThe client first detectsAdbWhether the server process is running. If not, start the server. When the server is started, it is bound to a localTCP5037And listen fromAdbCommands sent from the client -- allAdbAll clients use5037Port andAdbServer Communication.

　　Next, the server connects to all running simulators or mobile phones. It scans5555-5585To search for simulators or mobile phones.AdbThe daemon processes are connected through this port. It must be noted that each simulator or mobile phone uses an ordered port, an even port is used for console connection, and an odd port is usedAdbConnection, for example:

Emulator 1 , Console: 5554
Emulator 1 , Adb: 5555
Emulator 2 , Console: 5556
Emulator 2 , Adb: 5557 ...

That is, if the simulator andAdbIn5555Port connection, the connection to the console is5554Port.

After the server is connected to all simulators, you can useAdbCommand to control or access. Because the server manages connections and can receive multipleAdbClient commands, so any simulator or mobile phone device can be controlled from any client or script.

The following describes the functions that can be used to manage simulators or mobile phones.AdbCommand. IfEclipseAnd installedADTDevelopment in the plug-in EnvironmentAndroidApplication, you do not need to useAdbNow,ADTThe plug-in already provides transparent integration. However, it can still be used directly when debugging and other needs are required.Adb.

 

　　UseAdbCommand

UseAdbCommand usage:

      adb [-d|-e|-s <serialNumber>] <command>

When used, the program callsAdbClient. BecauseAdbThe client does not need to be associated with any simulators. Therefore, if multiple simulators or mobile phones are running, you need to use-DThe parameter specifies which one to operate,
