title: Android Studio: Use AndroidAnnotations
body: <p>So I wanted to try the new Android Studio and imported my eclipse projects (I generated a gradle build file). Worked pretty good.</p>
  
  <p>The only library which does not seem to work is AndroidAnnotations. 
  I selected the androidannotations-2.7.jar file under File > Settings > Compiler > Annotation Processing.</p>
  
  <p>As production source directory i selected "gen".
  But the generated file like MainActivity_ are not generated. What did I wrong?</p>
