title: Visibility scope project/module
body: <p>I have two projects/modules linked in Android Studio. One of them acts as an Api/Core, and I need that certain classes can by accessible only from this module but accesibles from all its packages (so “default” in this case is useless).</p>
  
  <p>But it seems that in Java it isn’t a modifier like internal (c#, swift). “Module” modifier was proposed for Java 7 but it wasn’t implemented.  </p>
  
  <p>So, is there any way to protect the classes of a module from the outside world without limiting their scope to the current package?</p>
  
  <p>Thanks!</p>
