应用程序构建：
依赖项{编译fileTree(dir：'libs‘)，包括：'*.jar') testCompile 'junit:junit:4.12‘testCompile 'com.android.support:appcompat-v7:25.3.1’testCompile‘com.google.Probuf:protobuf-java:3.3.0’编译'io.grpc:grpc-okhttp:1.4.0‘编译’io.grpc:grpc-protobuf:1.4.0‘编译'io.grpc:grpc-stub:1.4.0’}

正如我在评论中所写的，我理解grpc已经包含了一个更新版本的protobuf (3.3.1)。因此，您应该尝试使用gradle文件中的exclude(module: 'com.google.protobuf')排除grpc中包含的protobuf版本，或者将您的版本提高到3.3.1，如下所示：
