Wow I guess this thread is a bit old, but here goes anyhow.

Paul and I have been using libGDX quite successfully for our game on the OUYA. Supports and runs on Android phones and tablets and even the mighty OUYA gaming console. All you really need to do is include your library's jar files and make calls towards their classes.

Oxygene for Java is kind of like a superset of Object Pascal in that it incorporates a lot of the Java language functions into it, however the language is still very much Object Pascal with a few exceptions. This allows you to use suh libraries without the need to create all these translated wrappers. It does this rather elegantly actually.

Correct me if I'm wrong anywhere here Paul.
