Я хочу разрабатывать OpenCV-программы для Android с помощью NDK, для этого я попытался создать этот пример проекта в Android Studio, но при создании проекта возникают следующие ошибки: 

Build command failed.

Чтобы использовать собственный API-интерфейс camera2, установите APP_PLATFORM на android-24 или выше.В Android Studio это соответствует minSdkVersion в build.gradle скрипте.
