How to start Android Virtual Device and run an Android application in it

Before going through this post, please read my previous post on Android that explains how to create an Android application from eclipse.

To run an Android project using Android Virtual Device, you first need to launch the Android Virtual Device Manager inside the eclipse IDE. See the below screenshot to know where the Android Virtual Device Manager is located.

After clicking on the icon, the Android Virtual Device manager will get opened. It contains two tabs; one is Android Virtual Devices which shows all the created Android Virtual Devices and allows user to define a new one. The other tab is Device Definitions which shows some predefined Android Virtual Device definition. You can choose one from them to create the Android Emulator or you can define a new one. The choice is up to you. See the below screenshots for more details.

In both case, the newly created devices will be visible inside the listview of the first tab. Select one of them and click Edit to see its details.

Or select one of them and then click Start, then Launch to start the emulator. The Virtual Device takes some time (1-2 minutes) to start. When it is started, tap and then drag the lock to unlock it. See the below screenshot of Nexus S Android Virtual Device. Close the device manager. You can keep the virtual device opened as long as you wish.

your Android Virtual Device is now Ready and you can run your applications in it. To do that, right click on the project name and then choose Run As and click on Android Application. Bring your device manager to the front and see the output.
