• Flexible Gradle-based build system
• Build variants and multiple apk file generation
• Code templates to help you build common app features
• Rich layout editor with support for drag and drop theme editing
• lint tools to catch performance, usability, version compatibility, and other problems
• ProGuard and app-signing capabilities
• Built-in support for Google Cloud Platform, making it easy to integrate Google Cloud Messaging and App Engine

6 Select App Theme according to your App requirement.Here we have selected Holo Light Theme in which Holo.Light .DarkActionBar  theme style is selected your selection can be seen in styles.xml

7.Now your application is ready for development.With this default run through of the wizard we have created an app with one screen (Activity) with "Hello world" label in left corner.If you run the application you are already provided with one default emulator the application will launch in the emulator with the same screen you see in the layout editor.
