  • Minimum Required SDK is the lowest Android Version that your application is going to support

Once you are able to choose an icon, select “blank activity” to build your Android app. Once you click on blank activity, you will be asked to provide details for the activity. You can leave it blank if you wish.

To do that, you need to:

Launch AVD Manager
