There are way too many variables in the Android universe. Sync works fine for me and many others. I also have had plenty of problems and debug logs are the way to solve for your particular setup. You can also read many topics where sync issues have been resolved for those that had problems.

Hi,
As already said MTP Freeze is on system Driver level not in MMW as it can be easy replicated using plain Windows Explorer without even MMW started, we can only provide workarounds and supply info to manufacturers in order to release new USB/MTP driver to address the problem. Unfortunately many do not reply or do not want to fix it, thus WiFi or Direct to SDCard sync is the best option.

You'll have to give more details like versions of MMA, MMW and Android. Best yet is to send a debug log right after a sync failure and open a Support Ticket with the logID.
You and me both know the details of this problem Lowlander. MMW hangs when syncronizing with MMA. See:

And it's still not fixed till this day.

Really dissapionted with the synch feature. Sometimes works like a charm....and sometimes simply...no works. Cant connect. As simple as this. The reason??? Only God knows....

I cleared out all the problem directory and Filenames using a program called "advanced renamer" .

Since then I haven't had any issues with sync hanging or album art.

I did the original sync USB and then tried a Wifi after .... MMA still wanted to sync 900ish files that were already there. Annoying but everything works after

Hi,
I just synced MP3 with Cyrillic character filename without problems on Moto G1 LTE 5.1 Android without any issue.

This is true. See my post from May 3 in this thread. Don't know if it's because of the directory or file name, but it does happen.

MMA sync has the worst kind of Bug

by sirandar » Wed May 24, 2017 12:35 pm

MMA USB, Wireless and SD Card Reader sync are a pretty good tools when they work. They often don't and there are subtle differences between the 3 that add complexity.

Here are my observations:

SDCard Sync: Broken, don't waste your time, metadata doesn't get transferred anyway
Wireless: slow and not worth it for more than a few tracks
USB: On current devices it is pretty quick

Here is the issue:

MMA sync lets characters onto your Android devices that Android and MMA don't like. This causes sync failures and album art to not display when scrolling through the artist tab for multi artist albums. The art is there and it you click on a track or album it shows, but not when scrolling through the list of artists. It may also be causing other mayhem

The list of bad characters ( ) \ , . (except .mp3) @ & and any international


This was tested on two computers, one Win7 X64 and one Win10 ..... the result was the same ........ these characters cause issues and the only way to address is to use the <folder> and <filename> masks and make sure your MMW directories and filenames have absolutely none of these characters.

I can't reproduce. Files with accents in file name work fine. Albums with multiple Artist and .,: in the filename work fine.

It is added way back in MMW Due the similar issues.

Option is found at Insert SDCard -> Select it in Tree -> Options -> File Locations and add remap to all paths.
That feature is broken ....it does not remove characters Android doesn't like.

Why would am MMA sync ever let these characters on the device at all... The sync should have built in protection against this. Even with a USB sync things appear to work but really are broken

Any file or directory with .,():;& causes album art issues for any ablum that has more than one artist. The album art is missing when scrolling through artists in the artist tab ......but not when viewing tracks

For example all my 10,000 Maniacs albums had album art issues.... Took the comma out in the directory name to 10000 Maniacs do the problem went away immediately

Interesting ..... I thought my PC sd card reader sync worked perfectly but playlists were missing on phone after sync.

Looks like only a wireless sync can get those over which is a bad design limitation

EDIT.... the playlists were messed up by a unwanted phone to PC sync that happened (I probably checked it by accident once)

When I did a wireless sync of 10K tracks after the initial PC SD card sync, as usual after the file comparison stage the sync wanted to delete 978 tracks and resync wireless.
I watched the files delete on my phone ...... every single one had a bracket or other nonletter character in it almost all of 978. Yup checked off and on the vast majority had brackets in the song name

In your comparison process you have an equivalence statement that is not getting parsed properly if there are non-letter characters. it could be that ( needs to be (( or some other control character.

LOL ..... it is all crystal clear now including all my previous posts.

The root cause is MMA and Android cannot handle even a single special character or non-English character in the filename of any file that gets pushed to an android device.

Even one file getting pushed with these characters destabilized the whole sync. Even MM4 for windows doesn't like to have non-English characters in actual file names and there are issues but they are minor, I painstakingly removed every one from my W7 MM4 library a few years ago.

I incorrectly stated in previous posts that special characters in the <title> <album> and <artist> cause sync issues. They cause no issues in themselves, but cause fatal issues when the sync pushes them to the device with the special characters they contain. It was a case of indirect causation

I would very very strongly suggest that you change the default sync setting and profiles so the MM4 and MMA exactly replicates the PC directory and filename structure and character content in the sync process. A routine to report errors related to this issue or just replace/filter problem characters would also work.

I cannot be the only person with an international multi-language music library. This issue may be wasting a lot of interest in your very good software.
