> New MessageClient.sendRequest() method.

Unfortuantely there seems to be an old annotation on RpcService, so doc links don't work (404).

https://developers.google.com/android/reference/com/google/android/gms/wearable/MessageClient.RpcService

Code has

```
@ShowFirstParty
public interface RpcService {
    @Nullable
    Task<byte[]> onRequest(@NonNull String var1, @NonNull String var2, @NonNull byte[] var3);
}
```
