I'm using this software for syncing some folders on my Android phone (Nexus 4) and PC. The only issue which I found is that I have to launch app on mobile for starting the sync itself. Otherwise, PC's version shows "No connected devices". I have launched service on background but seems it's not enough. The only solution is keeping the Android version minimized. I tried to disable auto-sleep but it didn't help neither. If running the app is the necessary step, then for what service on background is required? Please help, I won't run software each time for starting the sync procedure. I would like to make it fully automatic Thanks!
