Серия уроков “Gps Tracker” На данном курсе создаем приложение для записи маршрутов бега или хотьбы с помощью Gps. Изучаем использование OSM (Open Street Maps) для отображения карты на экране смартфона, добавления маркеров, отрисовка маршрута, время прохождения маршрута, дистанция и средняя скорость. Используем базу данных и библиотеку Room для сохранения маршрутов. Используем таймер для отсчета времени. А также в приложении для работы в фоновом режиме создаем сервис для получения местоположения. Учимся… Подробнее »GPS Tracker
