did you manually modify the mesh.xml? because it cant be loaded as it is, the skeleton name does not match skeleton file name.
anyway, I edited mesh.xml to match the skeleton file, and opened it in desktop OgreSample. (which I strongly suggest to test your models and animations before going Android. you can see individual animations and skeleton there in all angles)
and I saw a totally different animation and skeleton.
this is how your model looks (with ninja's texture) the nucleus like thing in the middle is skeleton
I hide the mesh and zoomed in, here is your skeleton:
not sure where it's messed up. I'm really surprised Ogre3D viewer can display it properly.
what do you use to convert from binary to xml format? OgreMax's own converter? maybe you should try Ogre command line tools to do that (though I dont think it will help)
