Looking for a few people to test the Exposure Notifications API of @microg

- Update your microG to microg.org/dl/core-en.apk
- Install and set up your local gov corona tracing app xda-developers.com/google-appl
- Verify that microG settings has Exposure Notifications enabled and shows the app as using it
- When you are in public tomorrow, go to microG settings again and verify that "Collected IDs" shows a higher number
- Report back here with device name and android version+rom

Thanks!

@larma Thanks for your work. Does this require signature spoofing to work or do you see a way to build e.g. the german CWA app without signature checks for the play services?

Reason is I'm running GrapheneOS an have installed MicroG manually and don't have root to spoof signatures and I'm getting "GooglePlayServicesUtil: de.rki.coronawarnapp requires Google Play services, but their signature is invalid."

The original CWA app uses the play services client library which requires signature spoofing to communicate with microG.

It would be possible to modify the client library (its bytecode, as it's not open source) to not check for signatures. I also started working on an alternative client library (that doesn't do signature checks), but it's not fit for use yet.

If you just want to get CWA compatible app running without microG, watch out for coralibre.de/
