title: How to get all child values from firebase realtime database and store it in an array list
body: <p>I am familiar with firestore but uncertain how to get the values from realtime database. here is my database below
  <a href="https://i.stack.imgur.com/xcLxJ.png" rel="nofollow noreferrer">data base image</a></p>
  
  <p>As u can see I have UID under which I have stored multiple document references. here how I did:</p>
  
  <pre><code>           firebaseDatabase.getReference(firebaseAuth.getCurrentUser().getUid()).push().setValue(documentReference.getPath());
  </code></pre>
  
  <p>I want to get the whole document references under the UID and store it in an array list or just iterate through each document reference. Thank you</p>
