Having issues with building to a android device.

I have made a small scene with only a few sprites and a camera, but when exporting it to my tablet, a Neutab N9 pro, all i get is a blue screen. At first i thought it was the whole apk file being messed up somehow so I tested it by putting a song in the game, sure enough the song plays but i still only have a blue screen. I have fiddled with the camera trying out different settings and also the different build options but to no avail. Its been 2 1/2 days trying to sort this out, and am really needing a new idea on how to fix this issue.

make sure that the camera is allowed to see your object layer like this

if the camera can see the objects in your editor, make sure that your scene is added to your build window before sending to android.
