Answer 1

In my case error occurred while fetching a list of objects from shared preferences. The error was solved by adding TypeToken as shown below:

 public static  GenericClass getListOfObjectsFromSharedPref(Context context,String preferenceFileName, String preferenceKey ){

    SharedPreferences sharedPreferences = 
    context.getSharedPreferences(preferenceFileName, 0);
    Type type = new TypeToken>() {}.getType();
    String json = sharedPreferences.getString(preferenceKey, "");
    final Gson gson = new Gson();
    return gson.fromJson(json, type);
}
