title: Unable to make Android library resources private?
body: <p>created <strong>public.xml</strong> in values and added public resource there </p>
  
  <pre><code>&lt;resources&gt;
  &lt;public type="drawable" name="image_public"/&gt;
  &lt;public type="string" name="external_module_string_res_public"/&gt;
  &lt;public type="layout" name="activity_main_public"/&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>but still, I am able to access to all resource from library module in the Main project.</p>
