NoSuchMethodError after CollectionReference.AddSnapshotListener

rjhind commented 4 years ago

Xamarin.Android Version (eg: 6.0):

10.3.1.4

Operating System & Version (eg: Mac OSX 10.11):

macOS 10.15.5

Describe your Issue

Trying to use Firestore.CollectionReference.AddSnapshotListener with version 121.4.3-preview01 leads to a NoSuchMethod error. The AddSnapshotListener call succeeds but shortly afterwards the error is thrown:

So I guess this is when the Firestore libraries try to call back with a change.

This doesn't happen with the latest stable 71.1705.3 release however SetCacheSizeBytes() is unavailable in that version so I'm trying the latest preview release.

OK, looks like if I add a reference to Xamarin.IO.OpenCensus.OpenCensusApi then that fixes the method not found error. Can it be set so this package is automatically referenced?

Xamarin.IO.OpenCensus.OpenCensusApi is for sure transitive reference. From what I recall: GPS-FB uses GRPC and OpenCensus is some kind of telemetry library.

Now, why this was removed? I have no idea. It could be R8 or xamarin linker removing that method overly aggressive or some other problem. Not sure.

Could you create 2 bin logs:
