taskSnapshot.getDownloadUrl() method not working

To get imageUrl path from storage use this code:

uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        if (taskSnapshot.getMetadata() != null) {
            if (taskSnapshot.getMetadata().getReference() != null) {
                Task<Uri> result = taskSnapshot.getStorage().getDownloadUrl();
                result.addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        String imageUrl = uri.toString();
                        //createNewPost(imageUrl);
                    }
                });
            }
        }
    }});

that is all 😉

NOTE: Do not forget initialize StorageReference and UploadTask in your uploadFile method.

Edit: see this comment on why the approach in this answer doesn't work:

firebaser here This answer is wrong. While it at first may appear to work (since it compiles) the result of getDownloadUrl().toString() is not a download URL, but a string representation of a Task object. For a better answer, see stackoverflow.com/a/55503926 or the sample in the Firebase documentation.

In Firebase Storage API version 16.0.1, the getDownloadUrl() method using taskSnapshot object has changed. now you can use,

taskSnapshot.getMetadata().getReference().getDownloadUrl().toString()

to get download url from the firebase storage.

Try Using this it will download the image from FireBase storage

FireBase Libraries versions 16.0.1

Task<Uri> result = taskSnapshot.getMetadata().getReference().getDownloadUrl();
result.addOnSuccessListener(new OnSuccessListener<Uri>() {
      @Override
      public void onSuccess(Uri uri) {
             String photoStringLink = uri.toString();
      }
});
