1、項目的build.gradle文件加入：
classpath 'com.google.
2、模塊的build.gradle
頂部添加protobuf插件apply plugin: 'com.google.protobuf'android結點增加proto文件位置配置 sourceSets { main { proto { srcDir 'src/main/proto' include '**/*.proto' } java { srcDir 'src/main/java' } } }添加依賴 compile 'com.google.protobuf:protobuf-java:3.1.0' compile 'com.google.protobuf:protoc:3.1.0'增加protobuf結點protobuf { protoc { artifact = 'com.google.protobuf:protoc:3.1.0' } generateProtoTasks { all().each { task -> task.builtins { remove java } task.builtins { java {} // Add cpp output without any option. // DO NOT omit the braces if you want this builtin to be added. cpp {} } } } generatedFilesBaseDir = "$projectDir/src/generated"}
