Поскольку я использую googlemap в своем местоположении, каждые две минуты я хочу обновить местоположение, иногда метод onlocationchange не вызывается в моем приложении.Пожалуйста, помогите мне решить мою проблему.

Примечание: выполняется метод Onconnected, также отображается lastknownlocation, но метод onlocationchanged не выполняет. Это очень важно в моем проекте для расчетарасстояние за каждые 2 минуты. Пожалуйста, помогите мне
