Вставка Google Fit API Sleep и чтение DataPoint в сеансе

Пытаюсь (как в описанной теме) вставить и прочитать «Сон как фитнес-занятие». Основная цель - проанализировать весь сон с (когда был легкий / глубокий сон и как долго) за одну сессию. Подключение к GoogleFit выполнено успешно. Но у меня проблемы с Datapoint и Data Session. Возможно ты можешь помочь мне. Спасибо, ребята: D

Немного кода, где я думаю, что у меня проблемы. Я в курсе непонятного кода. я пытался скопировать я пытался вставить. в некоторых местах названия не подходят. Но как я уже упоминал. я пытаюсь выяснить фазы легкого и глубокого сна во время сеанса сна. Я собираю это свидание с sonyband 2.
