title: When does ADT set BuildConfig.DEBUG to false?
body: <p>In the newest version of ADT (r17) a generated constant was added <code>BuildConfig.DEBUG</code> that is set according to the build type. The problem I have is that it is never set to false, I expected it to change when doing "Android Tools -> Export Signed Application Package" but it hasn't for me. </p>
  
  <p>So how do I change the build type?</p>
  
  <blockquote>
    <p>Added a feature that allows you to run some code only in debug mode.
    Builds now generate a class called BuildConfig containing a DEBUG
    constant that is automatically set according to your build type. You
    can check the (BuildConfig.DEBUG) constant in your code to run
    debug-only functions</p>
