According to the Android documentation, ClipData use \"label\" as a kind of representation to the copied data.
ClippedData is a complex type containin
ClipData clip = ClipData.newPlainText( "text label", "content to be copied");
here text label describes what data is in clip
eg.
ClipData clip = ClipData.newPlainText( "user Name", user.getName());
we can retrive this by using
clip.getDescription ();
