Я постоянно получаю исключение безопасности при попытке запустить другое действие, отличное от моего MainActivity, код отлично работает, когда я запускаю свою MainActivity, но генерирует исключение, когда я попробуйте запустить любую другую деятельность, кроме MainActivity, я искал ответы и получил решение поместить -android: exported = "true" - в мой манифест, однако это не помогает проблеме, с которой я сталкиваюсь, любой помощь до сих пор будет высоко оценена.Java.lang.securityException: Permission Denial: begin Intent

* получил решение ставить -android: экспортироваться = «истина» - в моем Manifest * ... но вы положили его в каком-то случайном месте ... что был полный ответ что нашли? он говорит, чтобы поместить этот атрибут в элемент ''? does '' element has 'android: exported вообще? –
Selvin
Спасибо Selvin, он проходит через мой тег, теперь он отлично работает. догадываюсь, что вы не отвечаете на ложные ответы, всегда хорошо делать немного копания с моей стороны, спасибо вам большое спасибо. –
