Is jogl mobile (android) ready for use?

Is jogl mobile (android) ready for use? If so, where is a tutorial?

Any information would be nice so I can make video games for android more easily.

There are some demos using it but the whole thing might require some more cleanup.

Can you give some URLs where to find source code ? I downloaded the apks but I have no source.

The source code of the demos is here:
