Cloud Pub/Sub Client Error when publishing data

[munasinghecm]

I have followed your example that described Cloud PubSub (gRPC) with Android. It works fine alone. But when I add the same code and dependencies to my existing project got following error.

Looks like it's a problem with dependencies, but without looking at your code, it's complicated to find out more. Check at stackoverflow for similar problems, like this

The error what I fond is grpc library uses "com.google.protobuf:protobuf-java:3.0.0-beta-1" but in my app, I have used "com.google.protobuf:protobuf-java:3.2.0". So "com.google.protobuf:protobuf-java:3.2.0" replaces the library protobuf and give the error.
