Android APK打包脚本

build.gradle版本

同目录创建config.gradle文件写入需要的信息入

config.gradle文件内容

ext {
/*** 自定义APP运行环境* dev: 开发* test: 测试* pro: 生产*/
env = "pro"
/*** 动态参数配置，根据自己需要添加参数* APP_ID: 包名* VERSION_CODE: 版本号* VERSION_NAME: 版本名* HOST: 网络请求前缀*/
dev = [APP_ID: "包名",APP_NAME: "(开发版)",VERSION_CODE: 1,VERSION_NAME: "1.0.0",HOST: "网络请求前缀"
]
pro = [APP_ID: "包名",APP_NAME: "正式包",VERSION_CODE: 1,VERSION_NAME: "1.0.0",HOST: "网络请求前缀",
]
//签名文件
sign = [STORE_FILE: "文件地址",STORE_PASSWORD: "密码",KEY_ALIAS: "秘钥名",KEY_PASSWORD: "秘钥密码"]
}

build.gradle中如何引用

使用 apply from: ‘config.gradle’ 添加脚本文件
将build.gradle文件中的相关信息替换成脚本文件的内容

def env = project.ext.env // 环境
def config = project.ext[env] // 根据环境获取配置信息
def sign = project.ext.sign
//noinspection GradleCompatible
compileSdkVersion 31
buildToolsVersion "29.0.3"defaultConfig {applicationId config.APP_IDminSdkVersion 21//noinspection ExpiredTargetSdkVersiontargetSdkVersion 29versionCode config.VERSION_CODEversionName config.VERSION_NAMEresValue "string", "app_name", config.APP_NAMEbuildConfigField "String", "HOST", "\"${config.HOST}\""buildConfigField "String", "PATH", "\"${config.PATH}\""buildConfigField "String", "HALL_OID", "\"${config.HALL_OID}\""manifestPlaceholders = [FILE_PROVIDER_AUTHORITIES: config.APP_ID + ".fileProvider"]signingConfigs {release {storeFile file(sign.STORE_FILE)storePassword sign.STORE_PASSWORDkeyAlias sign.KEY_ALIASkeyPassword sign.KEY_PASSWORDv1SigningEnabled truev2SigningEnabled true}
}//设置打包生成的apk命名
buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'applicationVariants.all { variant ->variant.outputs.all { output ->if(!variant.buildType.isDebuggable()) {outputFileName = "${config.APP_NAME}_V${variant.versionName}_${new Date().format("yyyyMMddHHmm")}.apk"}}}signingConfig signingConfigs.release}
}

build.gradle.kts版本

创建的config.gradle文件，内容见上方config.gradle文件内容

build.gradle和build.gradle.kts的区别在于前面是常规的写法，后面是kotlin写法。

添加脚本文件

apply(from = "config.gradle")

替换内容

val env = extra["env"] as String
val config = extra[env] as Map<*, *>
val sign = extra["sign"] as Map<*, *>
namespace = config["APP_ID"] as StringcompileSdk = 34defaultConfig {applicationId = config["APP_ID"] as StringminSdk = 21targetSdk = 34versionCode = config["VERSION_CODE"] as IntversionName = config["VERSION_NAME"] as StringtestInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"resValue("string", "app_name", config["APP_NAME"] as String)buildConfigField("String", "HOST", "\"${config["HOST"] as String}\"")buildConfigField("String", "WEBSOCKET", "\"${config["WEBSOCKET"] as String}\"")buildConfigField("String", "APP_KEY", "\"${config["APP_KEY"] as String}\"")buildConfigField("String", "APP_SECRET", "\"${config["APP_SECRET"] as String}\"")manifestPlaceholders["FILE_PROVIDER_AUTHORITIES"] = applicationId + ".fileProvider"
}signingConfigs {getByName("debug") {storeFile = file(sign["STORE_FILE"] as String)storePassword = sign["STORE_PASSWORD"] as StringkeyAlias = sign["KEY_ALIAS"] as StringkeyPassword = sign["KEY_PASSWORD"] as String}create("release") {storeFile = file(sign["STORE_FILE"] as String)storePassword = sign["STORE_PASSWORD"] as StringkeyAlias = sign["KEY_ALIAS"] as StringkeyPassword = sign["KEY_PASSWORD"] as String}
}
//编写打包生成的apk名是使用了日期个时间的类型，kotlin不像build.gradle可以直接使用需要引入相关类
//import java.text.SimpleDateFormat
//import java.util.DatebuildTypes {release {isMinifyEnabled = falseproguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"),"proguard-rules.pro")applicationVariants.all {outputs.all {if (this is com.android.build.gradle.internal.api.ApkVariantOutputImpl)outputFileName = "${config["APP_NAME"] as String}_V${config["VERSION_NAME"] as String}_${ SimpleDateFormat("yyMMdd").format(Date()) }.apk"}}}
}

项目中使用脚本字段，先编译项目，生成BuildConfig
直接在项目中使用 BuildConfig.VERSION_CODE 获取包名或者项目版本。

其中 manifestPlaceholders = [FILE_PROVIDER_AUTHORITIES: config.APP_ID + “.fileProvider”] 创建的是FileProvider中的authorities属性

<providerandroid:name="androidx.core.content.FileProvider"android:authorities="${FILE_PROVIDER_AUTHORITIES}"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" /></provider>

项目中使用

FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".fileProvider", apk);

需要修改的话只需要在config.gradle脚本文件中修改相关字段并重新编译项目即可
