Android emulator runs on a specific device type. There are lots of android devices available on market.
The AVD Manager (AVD – android virtual device) have almost all of them configured. What you need to do is to create one of them in AVD Manager for your testing purposes. You can always create different device types and test the application before publishing to the android market.

So far we know that SDK version is used in creating the virtual device (using AVD Manager mentioned in Step 3 above). If there is a requirement to test the application on different device, then you need to make sure you have that version of the SDK available in your system. In order to download the new version, do below:

1. click Windows->Android SDK Manager
2. select required packages and then click “Install *** packages…”
3. in the next window, click on “Accept all” and click Install button
it will take a while to download and setup new SDK
