changed build system for Android from Ant to Gradle This change is due to an upgrade of the SDL library version used for building the Android version from 2.0.5 to 2.0.12, which does not use Ant anymore, but switched to Gradle several versions ago.
added Android project files To build Rocks'n'Diamonds for Android, the SDL library source files and the assets directory must be added to the project. See file "build-projects/android/README.txt" for details.
