title: Project Structure in Android
body: <p>I am new to Android programming and wanted to know about the project structure.</p>
  <p>I wanted to test my app on an Emulator but somehow I could see the three Java modules: tablet / mobile and shared.</p>
  <p>Does this really make a difference if I write the code in all the modules? I couldn't find a reason why this structure has been made?</p>
