The (Android Virtual Device) AVD Manager downloaded with the SDK can be used to create virtual devices to test the android applications. First, run the AVD Manager icon in the Eclipse IDE. Now you can create an Emulator by giving the following attributes.

1. Name : Device-1
2. Target : Android 2.3.3(API Level 10)
3. SD Card Size : 64 MiB
4. Skin : Default(WVGA800)
5. You can change the ram size, density and heap or add any new property in Hardware as you wish.

Run an application on the Emulator

Select the application and choose the “Run Configuration” from the menu item “Run”. Now you can select a virtual device which is compatible with the target SDK version, from the list of devices available. The devices you have created using the AVD Manager will be added to this list.
