I don't know where is the issue with this code? it gives a blank imageView in Nav header....

This is the code:

```
  final View header = navigationView.getHeaderView(0);
        TextView text = (TextView) header.findViewById(R.id.TxtUsernametitle);
        TextView Tmail = (TextView)header.findViewById(R.id.textmail);
       imageView1 = (ImageView)header.findViewById(R.id.imageView1);

        String Tusern = currentUser.getUsername();
        String Tmails = currentUser.getEmail();
        text.setText(Tusern);
        Tmail.setText(Tmails);
        String usId= currentUser.getObjectId().toString();
        ParseQuery<ParseObject> query = ParseQuery.getQuery("Profile");
        query.whereEqualTo("userID", usId);
        query.getFirstInBackground(new GetCallback<ParseObject>() {
            public void done(ParseObject object, ParseException e) {
                if (object == null) {

                    ParseFile fileObject = (ParseFile) object.getParseFile("picture");
                    fileObject
                            .getDataInBackground(new GetDataCallback() {

                                public void done(byte[] data,
                                                 ParseException e) {
                                    if (e == null) {
                                        // Decode the Byte[] into
                                        // Bitmap
                                        Bitmap bmp = BitmapFactory
                                                .decodeByteArray(
                                                        data, 0,
                                                        data.length);

                                        // initialize
                                       // ImageView imageView1 = (ImageView)header.findViewById(R.id.imageView1);

                                        // Set the Bitmap into the
                                        // ImageView
                                        imageView1.setImageBitmap(bmp);

                                    } else {

                                    }
                                }
                            });
                } else {
                }
            }
        });
