Unable to expand or select music folders to scan

I’ve read through two other posts where this issue has been identified. Both reference Android libraries being missing from the firmware loaded onto the device. 
 

Im using the latest version of the Poweramp application on Android 9 on a tablet that is designed for automotive use. It is running Android 9 for sure, not mislabeled to indicate a higher Android version. 
 

in the previous two posts references were made to missing “Documents” or “file” libraries. I’m working with the hardware providers support team and they need to understand specifically what library is missing that the Poweramp application is looking for. 

I have tried a full rescan etc 

specifically I am trying to expand the Sd card to navigate to a sub folder to select it. I am unable to expand, and instead it is asking me to enable a legacy mode, which also does not work.

The 'Files' app would be the default file explorer app on your device, for looking through and managing directories and files. Some manufacturers have their own versions, but on my Samsung it is just called 'Files'.

If that it not present or installable, try switching to File Access Legacy Mode in PA Settings > Misc, then go to the Music Folders list again.

Poweramp calls createOpenDocumentTreeIntent method only on Android 10 (SDK_INT=29 or SDK_INT=28 + PREVIEW_SDK_INT param).

So either you have Android 10 and no createOpenDocumentTreeIntent, or SDK_INT constant (the one which defines the OS version for app) is fake for your ROM, both cases means it's not "Android OS" anymore. May be you have some firmware update fixing these issues.

Ah ha! I bet that’s it. Yes. The manufacturer changed one of the labels to say it was Android 10, but it is actually Android 9. This will be corrected in their next update release to have it show in all places correctly as Android 9. 
 

Thank you! Also, in misc, I do not have the option to enable legacy mode, likely also caused by PA thinking it is Android 10, when it is only Android 9. So libraries etc that are expected are not there. Thank you. This makes things clear! 
 

why can’t the manufacturers just list the real versions ..... lol.
