title: How to get URL from Firebase Storage getDownloadURL
body: <p>I'm trying to get the "long term persistent download link" to files in our Firebase storage bucket.
  I've changed the permissions of this to</p>
  
  <pre><code>service firebase.storage {
    match /b/project-xxx.appspot.com/o {
      match /{allPaths=**} {
        allow read, write;
      }
    }
  }
  </code></pre>
  
  <p>And my javacode looks like this:</p>
  
  <pre><code>private String niceLink (String date){
      String link;
      // Points to the root reference
      StorageReference storageRef = FirebaseStorage.getInstance().getReference();
      StorageReference dateRef = storageRef.child("/" + date+ ".csv");
      link = dateRef.getDownloadUrl().toString();
      return link;
  }
  </code></pre>
  
  <p>When I run this I get the uri link that looks something like
  <em>com.google.android.gms.tasks.zzh@xxx</em></p>
  
  <p><strong>Question 1.</strong> Can I from this get the download link similar to: <em><a href="https://firebasestorage.googleapis.com/v0/b/project-xxxx.appspot.com/o/20-5-2016.csv?alt=media&amp;token=b5d45a7f-3ab7-4f9b-b661-3a2187adxxxx" rel="noreferrer">https://firebasestorage.googleapis.com/v0/b/project-xxxx.appspot.com/o/20-5-2016.csv?alt=media&amp;token=b5d45a7f-3ab7-4f9b-b661-3a2187adxxxx</a></em></p>
  
  <p>When trying to get the link above I changed the last row before my return, like this:</p>
  
  <pre><code>private String niceLink (String date){
      String link;
      // Points to the root reference
      StorageReference storageRef = FirebaseStorage.getInstance().getReference();
      StorageReference dateRef = storageRef.child("/" + date+ ".csv");
      link = dateRef.getDownloadUrl().getResult().toString();
      return link;
  }
  </code></pre>
  
  <p>But when doing this i get a 403 error, and the app crashing. The consol tells me this is bc user is not logged in /auth.
  "Please sign in before asking for token"</p>
  
  <p><strong>Question 2.</strong> How do I fix this?</p>
