The APK ditributed with Roidmi ( http://www.roidmi.com/ ) is sadly only in Chinese language. For some people (including me) that might be a problem. But the device is purely awesome so I just translated it to English.
Not everything is translated yet but I'm working on it. Also I encourage anyone to help me! If you want to help just fork this project. Add your translation and do the pull request.
