title: Unity3D android app, UI shows completely black, only once built to Android device
body: <p>I'm building a 3D virtual pet app for android mobile phones using unity 5.</p>
  
  <p><a href="http://i.stack.imgur.com/jbmkg.jpg" rel="nofollow">Below is a screenshot of the scene while running through unity itself.</a></p>
  
  <p>However when the app is built to my android phone (running android version 5.0.1), the green window on the right is completely black, leaving neither of the two progress bars visible.</p>
  
  <p>Each object is an 'image', added to a canvas.
  The Main window is a Green rectangle.
  Each progress bar is a black rectangle with a white rectangle on top of that, with another coloured rectangle on top of the white(This re sizes to show progress).</p>
  
  <p>I don't know what could be causing this issue. If there is any further information which could help please let me know, I've been struggling with this issue for a while now.</p>
