利用Android Studio将Protobuf文件生成Java文件 Android应用软件开发

配置Gradle 1、项目的build.gradle文件加入：

classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.0'

2、模块的build.gradle

顶部添加protobuf插件

apply plugin: 'com.google.protobuf'

android结点增加proto文件位置配置

sourceSets { main { proto { srcDir 'src/main/proto' include '**/*.proto' } java { srcDir 'src/main/java' } } }

添加依赖

compile 'com.google.protobuf:protobuf-java:3.1.0' compile 'com.google.protobuf:protoc:3.1.0'

增加protobuf结点

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" }

附完整的模块的build.gradle

apply plugin: 'com.android.application' apply plugin: 'com.google.protobuf'android { compileSdkVersion 25 buildToolsVersion "25.0.0" defaultConfig { applicationId "com.ydtf.nbmobile.protobufdemo4" minSdkVersion 16 targetSdkVersion 25 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" }buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }sourceSets { main { proto { srcDir 'src/main/proto' include '**/*.proto' } java { srcDir 'src/main/java' } } } }dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:25.0.1' compile 'com.google.protobuf:protobuf-java:3.1.0' compile 'com.google.protobuf:protoc:3.1.0' testCompile 'junit:junit:4.12' }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" }
