title: textColor: Unable to resolve color value
body: <p>I got a stange error (no <a href="https://stackoverflow.com/questions/4926388/unable-to-resolve-color-value">this</a> won't help...)
  I got a seperate layout for the tabbar. tabs_bg.xml is the layout. tab_text_selector.xml for the textColor and colors.xml. (Nameing of the colors might be misleading, but this is for testing)</p>
  
  <p>If I click on the Graphical Layout, I got the error: java.lang.NumberFormatException: For input string: "@color/tab_unselected"</p>
  
  <p>tabs_bg.xml:</p>
