При нажатии метод в режиме просмотра изображений не работает

Question

У меня есть фрагментный раздел, чтобы загрузить фотографию из галереи или камеры и отправить ее на сервер. У меня есть одна кнопка и одно изображение. Отображает просмотр изображений Но когда я нажимаю на просмотр изображений, он не работает и не отображает раздел.

Как это исправить?

И загружает ли этот код изображения размером более 2 мг?

загрузить фрагмент кода:
