I've used blender+gimp for creating textures. After making the final model, select it, jump into edit mode, then press u (or Mesh-> UV Unwrap, on the lower menu bar) and select "Smart UV Project" and click OK. Then change the editor type to "UV/Image editor" (Blue arrow).

If nothing is displayed then make sure all faces are selected.

Now on the lower bar click UVs->Export UV Layout. [GIMP magic happens there]. When you want to test testures, Alt+R refreshes ,go back to 3d view and select textured display mode (red arrow).

I've red somewhere that obj format isn't the best one for libgdx. The g3db is better. to obtain such file first download fbx-conv. In Blender click File->Export->Autodesk FBX, and save it in the folder with fbx-conv. then open command line\terminal and run:

fbx-conv.exe -f "filename.fbx"

Note that you must add to assets both .png and .g3db I used AssetManager to load model.
