Hi,
Maybe not too related to this issue, but on my android based car infotainment MMA is constantly wanting to rescan SDcard and USB as newly mounted storage even they were mounted and accessible before I turned the key off and put it in sleep mode for 5 minutes (UI boots in 3s).

Will try to catch some logs tomorrow.

Great, thanks for the help. No other storage was connected, only storage was the phone's internal memory.

Hi,
thanks for the Log, it helped.
The issue is tracked as https://www.ventismedia.com/mantis/view.php?id=17158
I am going to fix it and create a new build.
Can you confirm that no OTG storage was mounted(external storage via USB)?

Anyone who has any suggestion? I would really appreciate any help. It's such a drag having to switch to another application.

After some meddling it seems that the playlists empties and gets deletes everytime i fully close mediamonkey and then opens it again. Tried starting clean and removed what files i could find tied to the database. I now try to sync 1 playlist with 1 file in it and its gone when reopening.

Made a new log when from when i restart.

Edit: There is no database file in the log folder anymore after i tried starting clean.

Hi,
thanks for Log,
I can see there syncing new tracks only, no info about playlists (Log is too short).
I am afraid whether there is some issue with database corruption, which causes re-downloading tracks and deleted playlists is a side effect maybe.

At first, I need more Logs.
1) If you have synced all media playlists currently, please send me Log.
Your database is too big and is not included into the Log file, but backup should be store in MediaMonkey/logs/Database_<Log_ID>.zip
Please send me also this zip file to be able to compare your database before and after the issue.

2)When the issue occurs again, then send another log and also your database again.

Keep option "Update playlists from other apps" disabled.
Thanks.

Okay, an unexpected turnaround. I didn't solve the problem and Mediamonkey seems to be the cause of playlists getting deleted.

Everything went well for a couple of days, but then out of nowhere (or so I thought) it happened again. I frequently checked that the playlists were still there during the period everything worked, but I didn't use Mediamonkey to play my music. After a couple of days I wanted to update my playlists and started Mediamonkey but then all the playlists were gone and the whole process restarted. Since then I've experimented a bit and created backup of my playlists. I wanted to see if Mediamonkey would recognize the backups after next deletion. So after the next time they were deleted i copied the backup playlists to the playlist folder and started Mediamonkey again. They were immediately removed. I repeated the process a few times and it happens every time. Only the playlists in the playlist folder are removed, not the backups that i've put in a subfolder in the same directory (also tested having them in other places).

I have no idea if its relevant but I also have some trouble with tagging. Many of the tracks with foreign characters (like åäö), but also others (seems random), show up as chinese characters. I don't mind this problem so much that I need it fixed but thought I'd say it in case there could be a connection.

So, any new ideas?

It seems that i've solved the problem. Thought i'd write it here if someone else gets trouble with this phone. After some tweaking I managed to disable the stock music player and since then everything has been working all good. No re-downloads, database compressions or playlists disappearing. Thanks for the help and suggestions, much appreciated!

Hi,
To confirm that, do sync with MM and do not open it for some time, while checking folders.

When you catch it happening see battery usage and possible apps to blame.

Also you can block suspicious apps to access SD card under that app info advanced settings under permissions.

Other than that I was never new device you have, so I am not much of help there. It can be also manufacturer OS customization or pre-installed apps

I hadn't noticed it earlier but yes, my Playlist folder on the phone was empty. I rescanned just one playlist and it appeared in the folder for a while but then disappeared again.

If another app is messing with the files, how do I find out which app it is? I haven't downloaded any new apps to this phone that I can think of.

Hi,
3 things that are strange in your behavior:
1. After all playlist are lost MMA re scan library
2. /Playlist/ folder is empty which causes MMA to delete playlists
3. I guess New profile is created on sync?

All 3 points that some phone app cleared MMA files on maintenance that trigger MMA to re scan and reset settings.

Can you confirm that this is happening.

I updated to version 4.1.30.1914 and deleted all files manually on my phone and then rescanned them. Worked fine as usual for about two hours but then all playlists emptied again and now it wants to delete and download 940 of the tracks over again when rescanning.. Any other ideas?

Start with updating as sync issues have been fixed.
