title: Xamarin.Android: Get Firebase Storage Download URL
body: <p>I have an UploadTask to send an image to Firebase Storage and it works but now I want to get the respective download URL but I'm facing some issues.</p>
  
  <pre><code>var upload = childRef.DownloadURL;
  
  upload.AddOnSuccessListener(this);
  </code></pre>
  
  <p>I'm implementing the IOnSuccessListener interface so the function has to be:</p>
  
  <pre><code>public void OnSuccess(Java.Lang.Object result){
     //get url from result
  }
  </code></pre>
  
  <p>How can I cast the result to access the URL?</p>
