Вы можете использовать этот класс, чтобы получить Текущее или Последнее известное местоположение , если текущее местоположение в данный момент недоступно.
начать это действие, позвонив
startActivity(new Intent(getApplicationContext(), LocationFinder.class));
finish();
Теперь вы можете получить Местоположение в любой другой деятельности, просто позвонив -> LocationFinder.finalAddress
Требуется разрешение на местоположение
