Выключение экрана в Android с PARTIAL_WAKE_LOCK

Question

Я использую следующий код для отправки HTTP-запроса, когда устройство движется. Он отлично работает, когда я изменяю PARTIAL_WAKE_LOCK на SCREEN_DIM_WAKE_LOCK, и он поддерживает работу экрана и приложение. Однако при использовании PARTIAL_WAKE_LOCK устройство блокирует экран, и приложение перестает работать вообще. Мне нужен экран, поэтому я могу сэкономить заряд батареи, но переход на PARTIAL_WAKE_LOCK, похоже, не делает то, что он должен.

Не тратьте свое время. PARTIAL_WAKE_LOCK не препятствует андроиду войти в режим доз, так как вы можете читать here, и, следовательно, активность датчиков приостанавливается или, по крайней мере, откладывается. В моих тестах я видел, что только когда устройство подключено к источнику питания, поведение ожидается.
