title: Eclipse Libgdx android project doesn't export AndroidLauncher anymore
body: <p>I have a libgdx-android project in eclipse which I have been exporting successfully for weeks now. Today I noticed something strange when starting my apk:</p>

  <p>When examining the generated APK i noticed that the content of my src folder is not part of the APK src folder which means everything including "AndroicLauncher.class" is missing.</p>
  
  <p>Since there are no options I could configure when exporting the android application I'm pretty lost why this is suddenly happening now.
  Any ideas would be highly appreciated!</p>
