BoxFile download url android sdk

Hi everyone.

First i want to apologize for my english grammar mistake.

Ok so, i hit some issue with the Box android sdk.

I try to get the url of any file on box to download it.I have searched a lot on internet but a didn't found anything that work really.

What i understand on the several forums,is that to get the download url of a file,we need to share the file.

By download url , i means any link that download directly the file,which means that i don't want show the box html page to download a file.

And for share the file on the Box Android SDK , here is what i do:

boxApiFileInstance.getCreateSharedLinkRequest(ITEM_ID).setCanDownload(true)
                  .setAccess(BoxSharedLink.Access.OPEN)
                  .toTask().addOnCompletedListener(new BoxFutureTask.OnCompletedListener() {
                        @Override
                        public void onCompleted(BoxResponse response) {
                            if(response.isSuccess()){
                                   BoxFile boxFile= response.getResult();
                                   String downloadUrl= boxFile.getSharedLink().getDownloadUrl();
                                //This return me a web link to show the Box page to download the file
                            }
                            else{
                                   //Handle failure
                            }
                        }
                    }).run();

The download url variable as you can see, returns link for download url page or what i want is  a link to download directly the file.i spent almost one week on internet to find an solution, Can you help me please ?
