Пытаюсь разобраться и запустить код для приложения, в котором отображается карта и моё текущее местоположение. При этом всё это выполняется через запрос на разрешение доступа к геолокации, который нужно одобрить.
Код запускаю на своём устройстве через студию (на девайсе API 28), и сразу после запуска приложение крэшится. В логкате получаю ошибку:
java.lang.SecurityException: my location requires permission ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION
Как можно разрешить эту проблему? Погуглив, использовал разные решения, но пока безрезультатно. Поэтому решил и написать свой вопрос. Может быть есть нюансы в самой версии андроида, которые не дают приложению работать?
В манифесте:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="####.########.mygooglemap">
<application
