There are more than 1.4 million new Android devices which include both smartphones and tablets across the world which are tuned on. Basically, it is a time to extend the service to a wider audience. The Android Developers Blog states that the company previewed the App Translation service back in May 2013 during Google I/O 2013 and this service is fully functional and now is available for all the Android developers spread across different areas on the globe.
If you are and Android developer, you could locate the App Translation Service in the Developer Console at the bottom of the APK section and thereby start a new translation or manage an existing translation here.
