Google has made the switch from Eclipse to Android Studio official.
Google now states
If you have been using Eclipse with ADT, be aware that Android Studio is now the official IDE for Android, so you should migrate to Android Studio to receive all the latest IDE updates. For help moving projects, see Migrating to Android Studio.
Android Studio has come a long way since it originated several years ago, and is built around the gradle build cycle.
Although Android Studio has been officially anointed the successor to Eclipse, be aware there is not yet support for NDK development in Android Studio.
Android Studio is very different from Eclipse and migrating to something as radically different from Eclipse as Android Studio make take time for some projects.
I recommend starting to use Android Studio to do tasks similar to what you do today and get a feel for the scope required to move to Android Studio; so when you make the move your team is ready!
