title: Get all files from Firebase Storage
body: <p>I was able to successfully store files in the firebase storage, but now I am having  a problem. I am storing multiple images in a directory / folder but I am only able to retrieve one? How do I iterate through all files in a folder? I know you can do this with FirebaseDatabase snapshots by using an enhanced for loop, but this is not possible for FirebaseStorage, no?</p>
  
  <pre><code>FirebaseStorage.getInstance().getReference().child(listing.authorUid).child(listing.adId).getDownloadUrl().addOnSuccessListener(new OnSuccessListener&lt;Uri&gt;() {
         @Override
             public void onSuccess(Uri uri) {
                //for(Uri child : uri.getChildren()) ???
             }
         });
  </code></pre>
