issue with progaurd minifyEnabled

See original GitHub issue

Hello,

First of all, thank you guys for awesome work. Currently, I am using grpc on my android app and it crashes with below trace when minifyEnabled is true in gradle configuration. Is there any specific progaurd rule/ config for this ?

E: io.grpc.ManagedChannelProvider$ProviderNotFoundException: No functional channel service provider found. Try adding a dependency on the grpc-okhttp or grpc-netty artifact

@ @Nishant-Pathak I’ve added -keep class io.grpc.** {*;} before release, it works fine on all of my own android devices, but still receive the logs above from some android devices.
