Hi Nathan,
I don't have any problems with using GLES2 for Android. It is correct you don't
have a osgPlugins directory in your build output. You should however have a
static library (*.a) file for each of the libraries and plugins, e.g.
libosgdb_osg.a to load .osg files. Can you verify you do have this file?
Also in your Android.mk file, make sure you link against it by adding
"-losgdb_osg" to LOCAL_LDFLAGS, but if you are using the default
AndroidExampleGLES2 files it should all be there.
Finally double check you are loading the plugin in the OsgMainApp.hpp by
calling USE_OSGPLUGIN(osg).
I think since you are able to compile and link against the static libraries
this is not of much help, but I'm not sure what else could be going wrong.
