Could someone please provide a link which documents any JNI or similar interface that may allow combining Java with native code or, even better, an interface to the Flash Player ? I'd like to write applications in MIDP2.0 Java while implementing CODEC's or similar computationally intensive algorthms in optimized native code. However, I have not found documentation on this- all the mobile stuff seems to be implemented in one technology only. I found some interesting stuff using Flash and native code on a Pocket PC for mail handling ( iirc, this was from IBM). I'm sure that are other examples of mixed implementations on mobile devices but I haven't had much luck finding any.
