Description alexandre.rames 2011-11-24 10:30:43 UTC

debug output of the connect-transfer-eject session

Version:           2.4.3 (using KDE 4.7.3) 
OS:                Linux

Amarok correctly detects my Galaxy Nexus, but transferring songs does not work.
The progress bar appears, but after transfer nothing shows on the device.

The debug output of amarok shows 'NOT-IMPLEMENTED' warnings related to MTP, including one concerning MtpHandler::writeDatabase(). Maybe that is the reason the device's database is not updated (pure guess)?

It is interesting to note that this info can be found in the debug output:
amarok:     [SqlRegistry]   albums: 5 (-1) of 141 cached
amarok:     [SqlRegistry]  artists: 49 (0) of 120 cached
amarok:     [SqlRegistry]   genres: 1 (-1) of 24 cached
amarok:     [SqlRegistry]   tracks: 1 (-1) of 1722 cached

Reproducible: Always

Steps to Reproduce:
- Open Amarok.
- Connect Galaxy Nexus. It appears in the 'Local Music' section (you need the correct udev rules for it).
- Transfer songs to the device (drag and drop).
- Wait until the transfer is complete (progress bar bottom left).
- Eject drive.
- Open Music app on device.

Actual Results:  
Music app shows 'Music library is empty'

Expected Results:  
See the transferred songs.

Thank you for the feedback, changing status.

I noticed I didn't specify.
I was using the amarok binary provided with arch-linux 64bit.

Happy to offer further help (traces, tests,...) if you need.

Could you all please check if the files are in the root folder?
Comment 6 Christopher Bräuer 2012-01-01 12:03:56 UTC 
Can you please be more precise?Which files do you mean ?
Comment 7 Sebastian Frei 2012-01-01 16:49:44 UTC 
I think this is an upstream bug in libmtp which was fixed in version 1.1.1. See also this post: http://sourceforge.net/projects/libmtp/forums/forum/535191/topic/4887923

Well the tracks you tried to copy :)

But according to comment #7 this is an upstream problem with libmtp, so we need to wait for the new version to be available in your distributions. Please test again once you have the 1.1.1 version available.
Comment 9 Christopher Bräuer 2012-01-02 15:44:16 UTC 
In my phone, there is a special "music"-folder, where the songs are stored.

But anyway, it works now fine with libmtp 1.1.1.

Thanks a lot and a happy new year 2012!
