title: What value for @SuppressWarnings do I use to suppress the "Can be private" warning?
body: <p>I keep getting annoyed by the "Can be private" warning, however my <code>FirebaseRecyclerAdapter</code> will not work in that case. So, is there a <code>@SuppressWarnings</code> for that?</p>
  
  <p><strong>What I've tried:</strong></p>
  
  <p><code>@SuppressWarnings("all")</code> but that's not what I want.</p>
  
  <p><strong>Note:</strong> I am using Android Studio</p>
