[RyanShun-511]

I am new to gRPC, I hope you can help me.I'm having trouble writing the.proto file on Android Studio.I want to implement my client on an Android phone. What version of protobuf and what language are you using? Version: libprotoc 3.21.4. Language: Java

What operating system (Linux, Windows, ...) and version? Windows What runtime / compiler are you using (e.g., python version or gcc version) IDEA:Android studio

What did you expect to see I want to write an Android client using gRPC.

} I think I've got dependencies and plug-ins all worked out. Can someone help me with this? Thanks a million.

I had a similar issue. I was getting it from a plugin HIGAN's Protobuf plugin. Try changing it to standard JetBrains Protocol Buffer plugin

Hope it works afterwards.
