There were several issues for active tracking using device OPPO Reno

[Jaitoh]

There were several issues here:

• problem: 17:API exposure_notification_api is not available on this device ... Unknown_error_code(39501)
• device: OPPO Reno
• operating ColorOS version: v7.1
• Android version: 10
• app version: SwissCovid 1.1.0
• the Google Play Services version: 20.39.15(110400-335085812)
• output of adb shell dumpsys activity provider com.google.android.gms.chimera.container.GmsModuleProvider | grep 'nearby_en': com.google.android.gms.nearby_en [v203915000]

ApiException 17 with statusCode=39501 was an error in the ExposureNotification framework of Google that happened on devices not supporting bluetooth multiple advertisement. This issue has been fixed now by Google and should no longer happen. If it still does happen. on your device, please open a new issue and include the app version, the Google Play Services version as well as the output of
adb shell dumpsys activity provider com.google.android.gms.chimera.container.GmsModuleProvider | grep 'nearby_en'

ApiException 17 with statusCode=39507 is due to Google checking the app signature when using the ExposureNotification framework. Only our production signature (used for PlayStore builds only) is whitelisted, therefore it is currently not possible to use the ExposureNotification framework when the app is not downloaded from the PlayStore but build individually. We are hoping for a solution from Google to enable developers to use the framework also with non-whitelisted apps (signatures). We are also working on reproducible builds that will allow to verify that the APK from the PlayStore is built from the source code provided here.

For phones without Google Play Services we do not yet have a solution, the app currently uses the Google ExposureNotification framework distributed as part of the Google Play Services.

Did this error show up after installing the app? Or did it work for some time and just recently showed up?
