grpc-java在android中的使用

Question

我使用

protoc -I examples/src/main/proto -I examples/build/extracted-protos/main --java_out=examples/build/generated-sources/main --java_plugin_out=examples/build/generated-sources/main --plugin=protoc-gen-java_plugin=compiler/build/binaries/java_pluginExecutable/java_plugin examples/src/main/proto/route_guide.proto

生成代码。

当我修改这个原型文件的Android demo时，运行./gradlew installDebug我得到一个问题：

no suitable constructor found for HelloRequest()
            HelloRequest message = new HelloRequest();
                                   ^
    constructor HelloRequest.HelloRequest(CodedInputStream,ExtensionRegistryLite) is not applicable
      (actual and formal argument lists differ in length)
    constructor HelloRequest.HelloRequest(Builder) is not applicable
      (actual and formal argument lists differ in length)

Answer 1

我解决了这个问题：

protoc --plugin=protoc-gen-java_rpc=compiler/build/binaries/java_pluginExecutable/java_plugin --java_rpc_out=nano=true:"examples/build/generated-sources/main/" --proto_path="examples/src/main/proto/" --javanano_out=ignore_services=true:"examples/build/generated-sources/main/" "examples/src/main/proto/helloworld.proto"
