Изменение Time Picker приводит к сбою приложения

Question

Минутный диапазон на сборщике времени, чтобы использовать приведенный ниже код Java, все работает правильно, сборщик времени устанавливает диапазон на 0 и 30 минут, но когда я делаю слайд на сборщике времени, чтобы изменить минуты, приложение останавливается и показать это сообщение: GC_FOR_ALLOC освобожден 1582K, 50% свободен 8434K / , сообщение очевидно из-за сборщика мусора и появляется несколько раз, как приложение может блокировать само? Как я могу решить это? (Я утверждаю, что один и тот же код я использую уже в разных точках своего приложения, и у меня никогда не было проблем)
