You still need the javalite {} block in both protobuf.plugins and
protobuf.generateProtoTasks. I would suggest following these instructions
<https://grpc.io/docs/quickstart/android.html> to build the example gRPC
Android Hello World app (here is its build.gradle
<https://github.com/grpc/grpc-java/blob/master/examples/android/helloworld/app/build.gradle>),
confirm the example builds in your local environment then adapt the working
example to your project. If the Hello World app doesn't build for you, let
me know.Best, Eric On Sun, Jul 16, 2017 at 3:51 PM, <[email protected]> wrote: > I now have another problem.
