Android Question [SOLVED] Cannot Access External Storage on Motorola Ace 5G

[mmieher]

I have a Samsung Galaxy phone which I use for development. Everything fine there. I recently got a Motorola Ace 5G and my App cannot seem to create a directory?

There are no errors, however after running the test app below, the FILES app does not show the directory. I get an "unknown error" only when I try to access external storage.

Cannot find anything in forum about this.

Thanks for your help.

File.DirRootExternal

You´ll not be able to access this path any longer.
