title: Adding java folders to android studio project
body: <p>Started working on my first project using <strong>Android Studio instead of Eclipse ADT</strong>.
  I would like to add sub folders to contain java.classes in order to structure my app but are unable to obtain references to them in my activity</p>
  
  <p>structure is (with app name replaced)</p>
  
  <pre><code>src/main/[MyCompany]/[myAppName]/model/user.java
  </code></pre>
  
  <p>and</p>
  
  <pre><code>src/main/[MyCompany]/[myAppName]/helperClasses/SQLiteHelper.java
  </code></pre>
  
  <p>however I am unable to reference them either directly in code or by import, and are forced to put them in the appName folder with the activity to reference them. </p>
  
  <p>Is this simply a limitation in Android or is there a way to organize your project with folders better. I used the <code>new-&gt;folder-java</code> folder option to create folders</p>
