Я работаю в андроид-студии, и я triyng, чтобы импортировать фотографию из каталога с моего телефона и поставить ее на ImageView.My imageView не работает
В моем первом действии я попытался сохранить фотографию с помощью камеры, и я попытался сохранить URI с фотографии. Это работает.
В другой деятельности я попытался импортировать этот URI, но мой ImageView не изменился. Компилятор видел местоположение с фотографии, поэтому я думаю, что работает, но изображение не может импортировать фотографию ...
Не могли бы вы мне помочь?
