It seems that the QR code scanner you are using is not getting integrated with the companion app. So, what you need to do now is the following:
- Verify that the companion app is installed. (I am assuming this is true.)
- Build your app for the Android companion app and scan the QR code. Note, that by default, AppBuilder will suggest to build an application package for Android instead of build for the companion app.
- Locate the share button or option for the QR code (it might be a button in the app interface or you might call it from the menu button for the app).
- Share the app to the companion app.
In addition, so far, we have found out that this QR code scanner works good with the companion app.
Since this workaround is not really intuitive, we are already working on providing a built-in QR code scanner for a future version of the Android companion app.
