title: How to retrieve value from firebase without getting the unique key
body: <p>I am trying to retrieve an url from Firebase in Android. However, my problem is that I can't retrieve the url without also getting the unique key of the child.</p>
  
  <p>The value I am trying to retrieve is the following:</p>
  
  <p><a href="https://i.stack.imgur.com/CYRTi.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CYRTi.png" alt="Firebase Image"></a></p>
  
  <p>Down below is the code I use to retrieve the data from firebase.</p>
  
  <pre><code> final FirebaseDatabase database = FirebaseDatabase.getInstance();
      myRef = database.getReference().child("LoadItems");
  
      myRef.addValueEventListener(new ValueEventListener() {
          @Override
          public void onDataChange(DataSnapshot dataSnapshot) {
              for(DataSnapshot child : dataSnapshot.getChildren() ){
                  String key;
                  key = child.getKey();
  
                  Log.d(TAG, "onDataChange: " + key);
                  Log.d(TAG, "onDataChange: " + child.getValue());
              }
          }
  
          @Override
          public void onCancelled(DatabaseError databaseError) { }
      });
  </code></pre>
  
  <p>So what I am trying to get is what the url alone.</p>
