An important command that contains the Android emulator operation under the Tools folder of the SDK Adb,adb is all called Android Debug Bridge, which is the role of the debug bridges, with this tool, we can manage the status of the device or phone simulator, and can do the following:

(1) Quickly update the code in the device or phone simulator, such as app or Android system upgrade;
(2) Run the shell command on the device;
(3) Management equipment or mobile phone simulator on the predetermined port;

(4) Copy or paste the file on the device or phone simulator.

ADB's way of working is a special use of listening socket TCP 5554 and other ports to the IDE and QEMU communication, by default ADB will daemon the relevant network port, so when we run eclipse, the ADB process will automatically run, Debugging Android programs via Ddms in Eclipse, or manually, here are some common actions to refer to.

1. Version Information

D:\UNSETUP\ANDROID-SDK-WINDOWS-1.0_R1\TOOLS>ADB version

Android Debug Bridge Version 1.0.20


2. install the app to the emulator
ADB install [-l] [-r] <file>.

Where file is the decision path for the apk file that needs to be installed.

3. Uninstall an already installed app

(1) Method 1:

adb uninstall [-K] <package>.

Where the package represents the name of the packages that need to be uninstalled, and K indicates whether to keep the app's configuration information and cache data.

(2) Delete manually.
ADB shell
Cd/data/app
RM app.apk


4. Enter the device or simulator SHell
ADB shell
From the command above, you can enter the shell environment of the device or emulator, in which you can execute various Linux commands, and if you want to execute only one shell command, you can do the following:
ADB Shell [command]
Such as:

D:\UNSETUP\ANDROID-SDK-WINDOWS-1.0_R1\TOOLS>ADB Shell DF

/dev:49564k Total, 0K used, 49564K available (block size 4096)

/sqlite_stmt_journals:4096k Total, 0K used, 4096K available (block size 4096)

/system:69120k Total, 65508K used, 3612K available (block size 4096)

/data:76544k Total, 63684K used, 12860K available (block size 4096)

/cache:69120k Total, 1244K used, 67876K available (block size 4096)

5. turn to the originating port

You can use the forward command to forward any port-a specific host port for one emulator/device instance forwards requests to another different port. The following shows how to establish a forwarding from host port 7100 to emulator/device port 8100.

ADB forward tcp:7100 tcp:8100

Similarly, you can use ADB to create a UNIX domain socket interface named abstract, as shown in the following procedure:

ADB forward tcp:7100 LOCAL:LOGD


6. Copying Files

You can use ADB pull, the push command to copy files to a data file for an emulator/device instance, or to copy from a data file. The install command only copies an apk file to a specific location, unlike the pull and push commands, which allow users to copy arbitrary directories and files to any location on an emulator/device instance.

To copy a file or directory from a simulator or device, use the following command:

ADB pull <remote> <local>

To copy a file or directory to an emulator or device, use the following command:

ADB push <local> <remote>

In these commands, <local> and <remote> refer to the path to the destination file/directory on your own development machine (local) and emulator/Device instance (remote) .

Here's an example:

ADB push Foo.txt/sdcard/foo.txt


7. Search for an instance of the simulator/device
Gets a list of instances of the currently running emulator/device and the status of each instance, such as:

D:\UNSETUP\ANDROID-SDK-WINDOWS-1.0_R1\TOOLS>ADB devices

List of devices attached

ht843gz03305 Device


8. View bug reports

9. record the wireless communication log
Generally speaking, the wireless communication log is very many, at run time not necessary to record, but we can still through the command, set the record:

D:\UNSETUP\ANDROID-SDK-WINDOWS-1.0_R1\TOOLS>ADB Shell

# Logcat-b Radio

Logcat-b Radio

D/htc_ril (+): (t=1239390296) << 0

D/htc_ril (+): (t=1239390296) >> [email protected]=0

D/htc_ril (+): (t=1239390296) << 0

D/htc_ril (+): (t=1239390296) >> AT+CSQ

D/htc_ril (+): (t=1239390296) << +csq:29,99

D/htc_ril (30): 0

D/htc_ril (+): (t=1239390296) >> At+creg?

D/htc_ril (+): (t=1239390296) << +creg:2,3

D/htc_ril (30): 0


Get the ID and serial number of the device
ADB get-product

D:\UNSETUP\ANDROID-SDK-WINDOWS-1.0_R1\TOOLS>ADB Get-serialno

ht843gz03305

11. Via Remote shell-side run AQLite3 Connection Database

Through the ADB remote shell side, the database can be managed via Android's soft aqlite 3 command program. The SQLite 3 tool contains many use commands, such as. Dump to display the contents of the table, the. Schema can display the SQL create result set for the table space that already exists. SQLite3 also allows SQL commands to be executed remotely.

With SQLite 3, follow the previous method to log in to the remote shell side of the emulator, and then launch the tool to use the SQLite 3 command. When SQLite 3 is started, you can also specify the full path of the database you want to view. The emulator/Device instance saves the SQLite3 database in the folder/data/data/<package_name>/databases/.

Examples are as follows:

$ adb shell

# sqlite3/data/data/com.example.google.rss.rssexample/databases/rssitems.db

SQLite version 3.3.12

Enter '. Help ' for instructions

.... Enter commands, then quit ...

Sqlite>. Exit

When you start SQLite 3, you can send SQLite 3 through the shell side, command. Exit the ADB remote shell with the exit or <Ctrl+D> key combination.

  • Jdwp:<pid>

PPP <tty> [Parm] ...

To run PPP via USB:

  • [Parm] ... &mdash zero or more PPP/PPPD options, such as Defaultroute, local, Notty, etc.

You need to be reminded that PDP connections cannot be started automatically

View querying for Emulator/device Instances to get more information

Get-state

View the current status of the simulator/facility

Wait-for-device

If the device is not online, it is not allowed to execute, that is, when the instance state is device

The command can be reproduced in advance in the ADB command, commands in the command will not execute other commands before the simulator/device connection, the example is as follows:

ADB wait-for-device Shell Getprop

It is necessary to note that these commands do not start the ADB until all the systems start up, so no other commands can be executed until all the systems start up, for example, when the install is used, the Android package needs to be fully booted, for example:

ADB wait-for-device Install <app>.apk

The above command is only connected to the emulator/device connection on which the ADB service will be executed, and an error will occur before the Android system is fully booted.

Server

Start-server

Select whether the service starts the ADB service process

Kill-server

Terminate ADB service process

Shell
