            }
        });

        }
    }
}

Answer

If you look at the docs you’ll see that Resources.getSystem().getStrings will provide you with system wide strings, not the ones in your application (strings.xml).

Replace the following line

String url = Resources.getSystem().getString(R.string.song);

with the following.

String url = v.getContext().getResources().getString(R.string.song);
