Texture not showing on game objects

Ever object a make in blender and import into unity will not properly show materials or textures. When I try to apply a texture or a material to an object maked in blender it will not show it/render it/ or what ever you want to call it, it just changes to the basic color of the diffuse to the color of the texture.

unity3d 4.6 beta 17 (android platform)
blender 2.7.1 (.blender)

you should do uv mapping and set materials for it in blender check this link
