Toast.makeText(getParent(), "inside back prsseeeeeeee", Toast.LENGTH_SHORT).show();
            AlertDialog.Builder builder = new AlertDialog.Builder(getParent());

                    .setCancelable(false)
                    .setPositiveButton("Yes",
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int id) {
                                    UserProfileActivity.this.finish();
                                }
                            })
                    .setNegativeButton("No",
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int id) {
