title: How to delete multiple nodes in one request in firebase?
body: <p>I have two nodes from one root and I want to delete the data from both of them in one request. Both sub-nodes has the same key. I tried this:</p>
  
  <pre><code>Firebase firebaseRef = new Firebase(&lt;root_path&gt;);
  
  Map&lt;String, Object&gt; childUpdates = new HashMap&lt;&gt;();
  childUpdates.put(&lt;path_to_first_node&gt;, key);
  childUpdates.put(&lt;path_to_second_node&gt;, key);
  
  listToRemoveRef.updateChildren(childUpdates, null);
  </code></pre>
  
  <p>But it removed data from only the first node</p>
