Answer 1

This issue can be solved by using a different way to create the TypeToken instance (for the parameterized type Map):

Type collectionType = 
  TypeToken.get(
    $Gson$Types.newParameterizedTypeWithOwner(null,
      Map.class, Integer.class, WatchedEpisodes.class)).getType();

The next version of gson (I assume 2.8), will allow you to type this more easily:

Type collectionType =
  TypeToken.getParameterized(Map.class,
                             Integer.class,
                             WatchedEpisodes.class).getType();
