A directory that requires READ_MEDIA_... permission cannot be listed using the File component on Android 13+. (Error 908: The permission READ_EXTERNAL_STORAGE has been denied...)
I alsredy posted the blocks. What's the problem with creating 3 blocks yourself and listing a folder that contains media files. How was I supposed to know that?
Well, my suggestion is to make it as easy for the MIT App Inventor team to fix the bugs. And part of this is to provide an example project which elicits the error.
Also as in this case someone else could also do some tests based on your example to find a workaround. It is more likely that someone will do that, if there is an example project...
You already have that example project. Where exactly is the problem to add it into this thread?
As I said, which folder should I use?
How should I know which (non-shared) folder contains which files?
(Ok, I could use a Textbox, but I've already made the effort to uncover and write about this bug. I don't have to serve everything on a tray to everyone. )
