Сборка фонового местоположения Android в xamarin занимает вечность

Итак, я работаю с приложением, которое получает текущую широту, долготу, текущую скорость и т. д., используя данные GPS. Приложение не выдает никаких ошибок и успешно развертывается, и я использую свой телефон (Sony Xperia D 2005) для развертывания. Это. Во всяком случае, он говорит «Ожидание обновлений местоположения», но это занимает вечность ... Извините за все строки кода, которые я собираюсь вставить, но я не знаю, в чем проблема. Вот мой код MainActivity.cs: (я новичок в xamarin, и я не знаю, является ли эта часть кода причиной проблемы, поэтому, если вам нужен какой-либо дополнительный код, просто дайте мне знать...)
