                public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

                    if(task.isSuccessful()){

                        final String download_url = task.getResult().getDownloadUrl().toString();
                       databaseReference.child("image").setValue(download_url).addOnCompleteListener(new OnCompleteListener<Void>() {
                           @Override
                           public void onComplete(@NonNull Task<Void> task) {

                               if(task.isSuccessful())
                               {
                                   progressDialog.dismiss();
                                   Toast.makeText(Setting_activity.this, "Success Uploading.", Toast.LENGTH_LONG).show();

                               }
                           }
