Managing Virtual Devices
Virtual devices are used to run or debug applications intended for Android devices. You can configure virtual devices to emulate actual Android units by defining their hardware and software parameters.
To configure a virtual Android device, you need to open the Android Virtual Device (AVD) Manager. To launch it:
In the main menu, select Tools | Android | AVD Manager.
When you create or edit a run/debug configuration, select the Emulator option from the Target drop-down list in the Deployment Target Options area and click Browse next to Prefer Android Virtual Device.
In the Choose Device Dialog that opens if you select the Show chooser dialog when creating a run/debug configuration, select the Launch emulator option and click the Browse button next to Android virtual device.
For instructions on how to configure Android virtual devices, refer to Android documentation.
