Library fast scroll letters don't work

[manni122]

It started 2 or 3 beta updates ago. In library mode, sorted by album, I cannot fast skip to interpret starting with letters K to T. If clicking one of these letters it jumps to the last available above, in my case starting with J. From letter U and downwards all is again functioning.

Are you reporting a problem that you had that has been resolved?

If you are still experiencing the problem, do a full re-scan of library, try the same process on all songs library.

Thank you for reply. The issue has not been resolved. I uninstalled, reinstalled, did a full rescan. Did not help so far.

I suspect that sometimes this can be caused by invalid characters in the field that is being used as the sort index ('Album' in your case). But it's be hard to specifically diagnose without a copy of your library.

To have a smooth operation of Poweramp, it is good to take the pain to sort files. 

Avoid multiple layers of folders, use correct tag, multiple similar tags and files should be deleted, use similar files. Remove corrupt files, etc.

@Bencherished Most of that isn't really applicable in this case though.

As for now my library hasn't changed that tremendous. I will reduce the size of my library to get a glue of what might happen.

Thanks for helping me!

I agree that this is most likely the case. Often features like sorting and the fast scroll Android API are not able to correctly parse invalid language characters. Try to make sure you are using something like UTF-8 or UTF-16 within your tagging software to correct this.

But I can't figure out why K to T would not allow fast-skipping via the alphabet list, but earlier and later letters work. I think @maxmp might be able to add more with some diagnostic detail.

So far it seems that a reduced library with only 20 albums with different interprets does not show this strange behaviour. Anyway I still need to figure out what the bug in my personal library is. I am going to check UTF-8/-16 characters. Thanks all of you!

Try adding albums back in a bunch at a time and see if you can narrow down which songs cause the problem.
