Android Auto - incomplete list in Folder Hierarchy view

[returnofthem]

Me again! 

If I'm using Poweramp with Android Auto and I open the Folder Hierarchy view, the list of items seems to be truncated. In my case, approximately the first 50% of the folders in alphabetical order are shown and the remainder are missing. This isn't just a visual display bug, because if I use the "search by initial letter" function which filters the list down to the folders starting with a particular letter, then the letters corresponding to the missing 50% of folders aren't available to be chosen with that function.

For example:

• If I had a folder called "Aerosmith - Get A Grip" then that folder would be visible in the Folder Hierarchy view, and if I open the "search by letter" function then the letter "A" can be selected and that folder shows up in the filtered list.
• If I had a folder called "ZZ Top - Afterburner" then that folder does not appear in the Folder Hierarchy view, and if I open the "search by letter" function then the letter "Z" is disabled and cannot be selected as a filter option.

The folders show as expected in the Folder Hierarchy view in the Poweramp app on my phone even when it's connected to Android Auto, and I can select and play any of those folders from the phone - but of course that's not safe to do while driving. It seems to just be a problem with the list provided to Android Auto.

If more info is needed let me know and I'll try to provide it. Thanks!

How many folders are in the list, as there is an implicit limit for Android Auto.

Hi Andre, there are 430 folders so I wouldn't have thought it'd be hitting that limit.

I've done a few more experiments and, interestingly, the Albums list shows everything properly even though (due to some of the tagging) it's a longer list than the folders hierarchy. Unfortunately, because of the way I've structure my library, using the Albums list doesn't really work for me - I'd still much prefer to be able to use the folder hierarchy.

I've tried a few more things to get it working including a full library rescan, clearing the library folder selections and adding them back, and restoring library settings to default. Sadly I still haven't been able to get it to work.

The limits are based on Android Auto capacity, rescanning won't help. I don't know whether Folders Hierarchy tries to cache more than just the top level of folder names though.
