could also be that you don't have osgDB compiled statically for some reason
- it was looking for its shared library. Does it load an .ive or .osg file?
Or no files at all?

It load's nothing at all, no matter the size. I tried out cessna.osg and
cow.osg from the sample set, an indoor .wrl-model I have (just one blank
wall, 100MB), a larger 3ds file - all run fine on the desktop but not a
single model loads on mobile. I try it currently out with the Nexus 5 and
the NVIDIA Shield tablet - same results at both.

How do I make sure it uses the ".a"-files (static libraries) ? I just used
the Android.mk that is shipped with the example, added -lgnustl..., as
written in all blogs to the topic, set the OSG_ANDROID_DIR to the location
of the local OSG_Android root install location (the folder with "bin" and
"lib" inside). As ndk-build reports, LOCAL_STATIC_LIBRARIES is not set in
the Android.mk, instead all libraries are referred in LOCAL_LDFLAGS.
