I'm using Gnome Flashback with Ubuntu 14.04. When I plug in my Android 4.4 device by USB, it connects using MTP, and in Nautilus it looks like this:
So far, so good. In Clementine, it appears under the Devices section, like so:
If I double click on it, it does this:
... and then it finishes like this:
Which all seems promising. I do actually have a bunch of songs on there that I had long ago copied over using Banshee, but I won't hold it against Clementine for not seeing them. Maybe it wants it's own special folders or something.
In any case, from this point, I can't find any option for syncing any play lists or copying music to my device. I've right-clicked on everything and gone through every menu I could find. I've tried dragging and dropping. Nothing works.
Frustratingly, when I do Google searches on how to copy music from Clementine to Android, I get a lot of hits on how to get or use Clementine's Android remote control app.
How do I get Clementine and my Android device to sync?
