Locus on Chromebook Google Drive authentication error

I've just started using Locus (Pro) on my Chromebook Pixel and it seems to work fine except when trying to gain authorisation for my Google Drive. I get the error "Unsupported file format..." as shown in the screenshot.

Any ideas?

Good day Will,we already received one more same issue, but unfortunately users wrote us that it is not possible to a) create a bug report log by the same method as on Android and b) install custom APK app version that will print more information into a log.

Without a log or test over special version, I have unfortunately absolutely no idea how to solve this problem. Any chance you have rooted Chromebook device?


I would be happy to do what I can to help debug the issue. Sounds like installing a custom APK might be the best way to debug it unless you know of a way to create a bug report without entering developer mode?


Good day Will,

I'm not 100% sure that this method will work because I just made it, but we may try it if you have few minutes.

  1. sign for Beta test of Locus Map Free:
  2. install Locus Map Free from Google Play, it should now offer Beta version
  3. start and initialize the application
  4. enable Expert settings by: long click on "main menu" button (top left corner) and in the menu that appears tap on "Expert settings"
  5. now open app settings > Expert settings (at bottom) > enable Log to file

Uff, now various logs may be stored in Locus/logs directory.

So try your login to Google Drive. After error appears, check if there is some log in the mentioned directory and if so, attach it here. Thank you!
