Здравствуйте.
Столкнулся с непонятной для себя проблемой. Был рабочий класс, никаких изменений в него не вносилось, в какой то момент, перестал работать и выдает пустую переменную. Смотрели в класс втроем, но так и не поняли, в чем может быть ошибка. Буду рад, если кто-то поможет, т.к. подозреваю, что просто "замылился" глаз и не видим очевидного.
Исходный класс, из которого происходит вызов.

Класс, в котором должны получаться данные от GPS.
