hey Richard, thanks for helping ... in fact, i have installed SDK-NDK, read the CPLUSPLUS-SUPPORT.html doc, and preparing to compile my C++ STL stuff, but what i really am afraid is of JNI. There are interfaces depending of the filed's types, and i dont realize how to pass STL structures or pointers to them. I wonder if you have a kind of hello- jni example which you can share in this thread ?
