I made a application that need to save files on user’s phone, but I find that after recently update, every time when I try to save a file, it will return Error 2103/2104.
I have check whether it have no permission, but it still not work. I can sure my block have no bug.
I have a old app which created by elder kodular version, it can save file.
So, why my new app can’t save file?
