Как установить apk файл на 11 Android с помощью java

С толкнулся с такой проблемой, что при установке apk файла на 11 Android вылезает "Не удалось обработать пакет", перепробовал несколько способов с FileProvider, но всё-равно получаю такую ошибку. Пишу на java в Android Studio. Буду благодарен, если вы напишите свой пример установки apk файла;) build.gradle `
