ADB command Details (i)--Simulator related command set

For Android developers, it is not enough to have an android real machine if you want to test the effects of a program you have developed on all Android versions, although you will be brushing your machine, it will only waste your precious time, and this time using the ADB tool will be different. You can test your app to the desired effect on all versions of the Android emulator.

Another case is the latest development tools Android Studio to download HAXM when launching the simulator, even cumbersome configuration, if this time do not want to be so troublesome, then the ADB command to start the simulator will be your good choice. Here we describe all the commands associated with the simulator.

1. Get the system image of the emulator

You can use this command to get a list of system images that you can use in your system:

"Path-to-sdk-install"/tools/android list targets

Alternatively, you can use the following command on the Windows terminal:

C:\[path-to-sdk-install]\tools\android list targets

For example, you can enter the following command at the command prompt:

C:\users\liyuanjing>android list targets

The effect is as follows:

The reason why I did not enter the installation SDK directory is because I configure the installation path with this environment variable to go, this can save time, if you do not configure please refer to http://jingyan.baidu.com/article/ 17bd8e52f514d985ab2bb800.html the URL.

This command will list all the available system images in your system. If you still want more system images, you can install them through the SDK manager. In this list you want to write down the ID of the mirror, because in the following steps you need to use them to identify the system image.

2. Create an AVD

Use the following command to create an AVD

"Path-to-sdk-install"/tools/android create Avd-n [name of your new AVD]-T [System image Target ID]

You must give a name to the AVD you created, which can be specified by the-n parameter, and the system image ID you selected in the previous step must also be specified by the-t parameter. If everything is OK, you should have created a new virtual device with your own name.

For example, you can enter the following command at the command prompt:

C:\users\liyuanjing>android Create Avd-n liyuanjinglyj-t 14

The effect is as follows:

3. Start the AVD

You can use the following command to run the new AVD that you have given it a name:

"Path-to-sdk-install"/tools/emulator-avd [the name of the AVD]

Where [the name of the AVD] is the name you gave the AVD in the previous step. If everything works, your new AVD will start up.

For example, you can enter the following command at the command prompt:

C:\USERS\LIYUANJING>EMULATOR-AVD Liyuanjinglyj

The effect is as follows:

4. Extended Simulator function

Virtual one memory card or one extended storage device

When creating a virtual device, you can use the-c parameter to have the newly created device also have some extended memory, the format of the command is as follows:

Android Craete-avd-n [AVD device name]-T [image ID]-C [Size][k| M

For example, the following command:

Android Create-avd-n virtdroid-t 1-c 128

You should obviously enter the size of the new virtual memory card, and you also need to specify whether the unit is K (Kbytes) or M (MBytes).

Sets the internal storage size.

Another useful thing you might want to do is to specify the size of the internal storage for the virtual Android device. When using the emulator command, you can use the-partition-size parameter to set it. The format of the command is as follows:

EMULATOR-AVD [name]-partition-size [size in MBs]

You need to enter the size of the system partition. By default, the unit is megabytes (MB)

5. Display the currently running emulator

The command is as follows:

ADB devices

The effect is as follows:

6. Display all AVD and details of the system

The command is as follows:

Android List AVD

The effect is as follows:

7. Delete the AVD

The command is as follows:

Android Delete avd-n [simulator name]

For example, you can enter the following command at the command prompt:

C:\users\liyuanjing>android Delete Avd-n Liyuanjinglyj

The effect is as follows:
