no suitable constructor found for HeaderItem(int,String,)

I got following error when I try to build android TV sample application.

The reason of this error happens is because the definition of the constructor HeaderItem.HeaderItem(long,String) has changed. We need to change

from HeaderItem(id, string, null) to HeaderItem(id, string).

So we need to delete “null” argument for all occurrences in the function.
