A sample Kotlin Android client with gRPC and Protobuf!
Before working, you will either need to make the protobuf module, or run the project to generate the Java and gRPC protobuf source code.
After that, it's as simple as adding your own .proto files to the proto module and building your app in your app module!
The sample uses the grpc sample java server. To set it up see https://grpc.io/docs/quickstart/android.html
To access a local server from the AVD, use IP 10.0.2.2
