Duplicate class error in gRPC dependencies when running the app

Question

I was beginning to try gRPC on android and added all the dependencies. When I want to run the project I get the following error. It's my first time implementing gRPC in android and it's starting to get annoying right from the start.

Please help me, I've been stuck on this for hours!! Thanks

Answer 1

The protobuf-lite package was a short-lived name. Protobuf only released two versions of it (3.0.0 and 3.0.1) before renaming it to protobuf-javalite.

You are depending on the old name: com.google.protobuf:protobuf-lite:3.0.1. Replace that dependency with com.google.protobuf:protobuf-javalite:3.17.2 to match the protoc version.
