Android Studio is Google's official IDE to develop Android applications. It was introduced by Google in 2013 at their annual developer conference Google I/O. After over a year and a half of active development, Android Studio hit its official stable release 1.0 in December 2014. It was based on IntelliJ IDEA software. Let's see how it differs from Eclipse:
It provides a live layout editor with real-time rendering (WYSIWYG)
It uses the Gradle build system against the traditional Apache ant build system
It provides advanced code completion
It has inbuilt template-based wizards for common Android designs
It offers built-in support for Google Cloud Platform, which helps integrate Google Cloud Messaging (GCM) and the App Engine seamlessly
It provides support for Android Wear
