title: Android src/main/java folder
body: <p>I'm new to android and android studio. The project i'm currently working on has src/main/Java and all the java stuff are under this folder. Also there is a module in the project with the same hierarchy. I was wondering if i can change this structure ? Is this structure imposed by android studio? by gradle? 
  I would like to remove the "main/java" part and move all my code under the "src" folder. (org,com and etc will move two levels up)
  Is there anything that will keep me from doing that ?</p>
