The four Android simulators and the corresponding four 'Google APIs 'are listed here. Google Maps its own applications in the Google APIs simulator type, therefore, to develop Google maps and other Google-specific applications, a corresponding Google APIs simulator must be created.

Create a simulator

To enable Android applications to run on simulators, you must create a simulator () AVD.

(1) Create AVD in eclipse

• In eclipse. Choose Windows> Android SDK and AVD manager]

• Click virtual devices in the left-side pane and click New on the right]

• Enter the device name and select the target API. the SD card size is smaller than 9 MB, and the skin value is optional. Currently, the default value of hardware is used.

• Click Create AVD to create an AVD.

(2) create AVD through the command line

Create an Android-7 Simulator

$ Android create AVD -- Target 5 -- name android7cpu

[Android create AVD]Create a simulator

[-- Target 5]The simulator uses the simulator type with ID 5.

[-- Name android7cpu]Name the simulator "android7cpu"

Result:

Android 2.1-update1 is a basic Android platform.

Do you wish to create a custom hardware profile [No]

Created AVD 'android7cpu 'based on Android 2.1-update1,

With the following hardware config:

HW. LCD. density = 160

Check the existing simulator:

$ Android list AVD

Result:

List existing AVD

Available Android Virtual Devices:

Name: android7cpu

Path: C:/Documents and Settings/Administrator/. Android/AVD/android7cpu. AV

Target: Android 2.1-update1 (API level 7)

Name: mydevice

Path: C:/Documents and Settings/Administrator/. Android/AVD/mydevice. AVD

Target: Android 2.2 (API Level 8)

Set AVD environment parameters:

Enable eclipse [run]> [debug deployments...] and then select Android Project (helloword) under [Android Application] In the list on the left ).

On the "android" tab on the right, you can select a project and the "launch action" tab are default lunch default activity.

[Target] Tab

In deployment target selection mode, select automatic and select AVD in the list below, and view AVD details.

During running, CTRL + F12 switches to the horizontal and vertical display of AVD.

Set AVD settings

Skins: hvga (default), qvga, wqvga400, wqvga432, wvga800, wvga854

The default value is hvga. You can add the -- skin qvga-L option after creating the AVD command line to set it to qvga, "-L" indicates (landscape) "-P"
