title: How to remove child nodes in firebase android?
body: <p>I have a number of child nodes in my firebase db and I want to delete only one child node.</p>
  
  <pre><code>Firebase firebase=new Firebase("..address..");
  
  firebase.push().setValue(classObj);
  </code></pre>
  
  <p>//here classObj is a class object which has a getter and setter for an integer id</p>
  
  <p>Now that I have pushed multiple objects I want to delete only one based on the id in the classObj</p>
