title: Naming feature module packages
body: <p>In a multi-module project where the package name of the 'app' module is:</p>
  
  <p><code>com.example.app</code></p>
  
  <p>Should additional 'feature modules' <em>add on</em> to this package name, like so:</p>
  
  <p><strong>A)</strong> <code>com.example.app.feature</code></p>
  
  <p>Or is it okay to omit the app name (default behavior of Android Studio):</p>
  
  <p><strong>B)</strong> <code>com.example.feature</code></p>
  
  <hr>
  
  <p>Are there potential conflicts down the road if I publish two apps with feature modules that have the same package name (because I omitted the app name)?</p>
