[osg-users] Android osgPlugins

[Rafa Gaitan]

Hi Christian,

I've just uploaded a fix to osgAndroid to fix all the linkage problems with
stl, I changed it to use the shared gnu stl library and inside the Java
code I'm loading it before load the osg jni library.

I hope this fixes your problems, I've just made a quick test with osgsimple
and it worked so far.

Regards,
Rafa.
