For a couple of years now we have been using AndEngine in our development to craft with graphics for our applications. Its a wonderful APK that has worked flawlessly and improved significantly over time. However, ever since Nicolas Gramlich, its main developer went to work for Zynga things has slowed down somewhat and newer developments like Gradle support is simply not there yet. As we have been considering using Android Studio as a more modern IDE (compared to Eclipse), Gradle has been one of those new features we have been struggling with lately. As a viable alternative we found out about libGDX through a tutorial on game programming in Android Studio. We are currently looking through the API, and it does look very promising! We might come back later with a comparison between the two.
