Syncing fails on Android when the app is not in foreground

Open erpas opened this issue 2 years ago • 2 comments

On Android, when syncing a project, the app needs to be in foreground. If it goes background or the phone screen is off, it will most probably fail randomly leaving the project locked server-side. Users need to wait 5-10 minutes for the locks being cleared to make another attempt to sync the project.

Steps to reproduce:

  1. Turn off wifi (it seems to resume syncing normally when on wifi) - we are trying to reproduce the problem as a user in the field
  2. Modify a project on your mobile - possibly add some heavy files so syncing would need some time to complete
  3. Start syncing (Other users can't sync from now on)
  4. Receive a phone call or start using another app for a few minutes -> syncing fails
  5. Turning your mobile screen off would result in a failure either

An excerpt from a log file when another app was used (from 12:03:48) during syncing - it fails after about 10 minutes at 12:11:03 when user switched back to MM app.
