Google has recently extended their Playservices API so that the data privacy friendly German corona warning app can run in the background and continue to send and receive Bluetooth tokens to measure distances to other smartphones running the app.
Well, Fairphone Open OS comes without Playservices. With the SDK the API should be publicly available. Is there a way to either emulate or implement those parts that allow a background app to access Bluetooth? Would Micro-G be a workaround?
Since the changes to the Playservices are very recent, I guess Micro G does not implement those. This PS-API is -to my understanding- the only obstacle that the open source corona app would have to overcome to become available of F-Droid. A playservices dependency will a killer there.
