Technical details

• Device name: Fairphone 2
• Android version: 10, LineageOS + microG version 0.2.19.211515
• App version: 2.2.1

Describe the bug

I just tried to do the necessary steps for "Testergebnis abrufen" to learn any new workflows (I do this after each CWA update). When clicking on "Einverstanden" I now get an error message reading "Google Play-Dienste aktualisieren: Corona-Warn wird nur ausgeführt, wenn du die Google Play-Dienste aktualisierst". This was not the case with app version 2.1.2.

Steps to reproduce the issue

Expected behaviour

Open the QR-Code reader.

Possible Fix

When tapping the error message the QR-Code reader opens. Not sure if registering a test would work, as I have none available to scan.

Additional context

I'm using LineageOS for microG, microG version 0.2.19.211515 (https://github.com/microg/GmsCore/releases/tag/v0.2.19.211515)

For reference, this is the issue in the microG repo:
microg/GmsCore#1469

The cause might be the new and improved error handling: #2995

It might be helpful to have a look at the logs here.

This reminds me on #75 (comment) : similar configuration, slightly different context.

Hey @Diapolo ,

Can you make an error report while reproducing the issue (see here for a How-To) and tell us the report ID? This will help us to investigate the problem quicker.

As the others have pointed out, having microG might be the cause of the problem here. We'll se what we can do about it. Tracking ID: EXPOSUREAPP-7264

It looks like the issue is your microG version is not supporting the preConsent authorization introduced by Google 2 month ago. A not available Google method will show this popup

I'd love to send an error report, but it seems you also require SafetyNet for sending error reports? I'm getting the message: "Etwas ist schiefgelaufen. Die Befragung kann aktuell nicht aufgerufen werden. Bitte versuchen Sie es später noch mal (Fehlercode ATTESTATION_FAILED)."

My phone is rooted and so doesn't pass SafetyNet...

[heinezen]

@Diapolo Ah I didn't think about that. Thanks for trying anyway. It does not work on microG currently, although we are thinking about alternative solutions: corona-warn-app/cwa-wishlist#356

Just to make everyone else here aware of this too, @Diapolo has opened a corresponding issue for microG and @mar-v-in added a change that fixes this behavior in microg/GmsCore#1469 (comment).

@heinezen Would be really nice to not enforce SafetyNet or implement alternative solutions :). At least the commit mentioned by @fynngodau fixed this issue here. So closing the ticket.
