Textures do not show on obj models.

[Jaconici]

I'm having an issue thats driving me mad, I have built a simple app with a sceneview and added a simple model of a rock to the scene and it works, textures load etc. However, I then wanted to move on my using my own obj model which I exported from blender, and the model loads geometrically correctly, but shows only a smooth uniform greyish colour (which actually depends on the textures I'm using so if I use an orangey texture its smooth orange etc). I've checked the mtl files, obj and sfb a hundred times. All file calls point to the correct place and I don't get any error messages, just no texture or bump mapping! Here's the code for all of those mentioned files. mtl:

Blender MTL File: 'Mercury.blend'

I'd add the obj but it's very long, so here's the important lines

Blender v2.79 (sub 0) OBJ File: 'Mercury.blend'

www.blender.org

mtllib mercurymtl.mtl o Mercury_Sphere

usemtl Material.001

Any ideas how to proceed? Thank you

what about texture coordinates and/or UV? is it correct?

By texture and UV coordinates do you mean the co ordinates found in the obj files? I haven't edited them and theyre far too long for me to know if they're "correct", not really readable. I've attached the whole obj file in txt format. mercuryobj.txt
