1. 添加 maven 仓库
1. 1. settings配置
1. 1.1. settings.gradle
repositories { maven {url 'https://maven.aliyun.com/repository/public/'} mavenCentral()}1. 1.2. settings.gradle.kts
repositories { maven { setUrl("https://maven.aliyun.com/repository/public/") } mavenCentral()}1. 2. gradle配置
1. 2.1. build.gradle
implementation 'com.github.bumptech.glide:glide:4.12.0'1. 2.2. build.gradle.kts
implementation(libs.glide) 版本号在gradle文件夹下 libs.versions.toml文件中添加
1. 2.2.1. build.gradle.kts
libs.versions.toml文件用来抽离依赖来加载，文件由 4 个主要部分组成：
（1）[versions]部分用于声明可以被依赖项引用的版本
（2）[libraries]部分用于声明坐标的别名
（3）[bundles]部分用于声明依赖包
（4）[plugins]部分用于声明插件
注意：不要使用驼峰命名方式，单词使用 - 分割：
[versions]groovy = "3.0.5"checkstyle = "8.37"[libraries]groovy-core = { module = "org.codehaus.groovy:groovy", version.ref = "groovy" }groovy-json = { module = "org.codehaus.groovy:groovy-json", version.ref = "groovy" }groovy-nio = { module = "org.codehaus.groovy:groovy-nio", version.ref = "groovy" }commons-lang3 = { group = "org.apache.commons", name = "commons-lang3", version = { strictly = "[3.8, 4.0[", prefer="3.9" } }[bundles]groovy = ["groovy-core", "groovy-json", "groovy-nio"][plugins]versions = { id = "com.github.ben-manes.versions", version = "0.45.0" }2. Android Studio 如何配置打包后的文件名称
我们在新建一个项目然后直接进行Build apk，可以生成一个app_debug.apk的apk文件，那么文件是怎么产生的呢？
2.1. build.gradle
//**********打包设置开始********** //自定义生成的apk的地址及名称 def apkName; signingConfigs { release { v1SigningEnabled true v2SigningEnabled true storeFile file('./keystore/insour_szyj.keystore') storePassword 'insour_szyj' keyAlias 'insour_szyj' keyPassword 'insour_szyj' } debug { v1SigningEnabled true v2SigningEnabled true storeFile file('./keystore/insour_szyj.keystore') storePassword 'insour_szyj' keyAlias 'insour_szyj' keyPassword 'insour_szyj' } } buildTypes { debug {// minifyEnabled false//混淆 minifyEnabled true shrinkResources true // 不显示Log buildConfigField "boolean", "LOG_DEBUG", "false" proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' aaptOptions.cruncherEnabled = false aaptOptions.useNewCruncher = false apkName = "szyj.apk" signingConfig signingConfigs.release } release {// minifyEnabled false//混淆 minifyEnabled true shrinkResources true // 不显示Log buildConfigField "boolean", "LOG_DEBUG", "false" proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' aaptOptions.cruncherEnabled = false aaptOptions.useNewCruncher = false apkName = "szyj.apk" signingConfig signingConfigs.release } } android.applicationVariants.all { variant -> variant.outputs.all { if (outputFileName.endsWith('.apk')) { //这里使用之前定义apk文件名称 outputFileName = apkName } } }// android.applicationVariants.all {// variant -> variant.outputs.all { output ->// def date = new Date().format("yyMMdd",// TimeZone.getTimeZone("GMT+08"))// if (variant.buildType.name == 'debug'){// output.outputFileName = "项目名称_" +// "${android.defaultConfig.versionName}_${date}_debug.apk"// }else if (variant.buildType.name == 'release'){// output.outputFileName = "项目名称_" +// "${android.defaultConfig.versionName}_${date}_release.apk"// }// }// } //**********打包设置结束**********2.2. build.gradle.kts
//**********打包设置开始********** signingConfigs {// create("release") {// storeFile = file("./keystore/insour_szyj.keystore")// storePassword = "insour_szyj"// keyAlias = "insour_szyj"// keyPassword = "insour_szyj"// } getByName("debug") { enableV1Signing =true enableV2Signing =true enableV3Signing =true enableV4Signing =true storeFile = file("./keystore/insour_szyj.keystore") storePassword = "insour_szyj" keyAlias = "insour_szyj" keyPassword = "insour_szyj" } register("release") { enableV1Signing =true enableV2Signing =true enableV3Signing =true enableV4Signing =true storeFile = file("./keystore/insour_szyj.keystore") storePassword = "insour_szyj" keyAlias = "insour_szyj" keyPassword = "insour_szyj" } } buildTypes { debug { isMinifyEnabled = false isShrinkResources = false proguardFiles(getDefaultProguardFile( "proguard-android-optimize.txt"), "proguard-rules.pro") } release { isMinifyEnabled = false isShrinkResources = false proguardFiles(getDefaultProguardFile( "proguard-android-optimize.txt"), "proguard-rules.pro") } } // 输出类型 android.applicationVariants.all { // 编译类型 val buildType = this.buildType.name val date = SimpleDateFormat("yyyyMMddHHmmss").format(Date()) outputs.all { // 判断是否是输出 apk 类型 if (this is com.android.build.gradle .internal.api.ApkVariantOutputImpl) { this.outputFileName = "szyj" + "_${android.defaultConfig.versionName}_${date}_${buildType}.apk" } } } //**********打包设置结束**********3. sourceSets配置
3.1. build.gradle
sourceSets { main { jniLibs.srcDirs = ['libs'] } }3.2. build.gradle.kts
//jniLibs目录指向libs目录 sourceSets { getByName("main") { jniLibs.srcDirs("libs") } }4. BuildConfig不生成
新建了一个demo，其依赖的AGP版本是8.0.0。但是在运行过程中报了一个错误就是找不到BuildConfig。
重新build了下代码，然后找编译后的代码，发现确实没有生成BuildConfig。清缓存，重启AS都没有用。之前代码相比，也就是AGP的版本升级了下，那猜测是不是跟AGP8.0.0的版本有关，于是在BuildType中手动添加了个buildConfigField，想以此方式强制生成下BuildConfig。
运行报错
Build Type 'debug' contains custom BuildConfig fields, but the feature is disabled.
提示BuildConfig 处于禁用状态…看来是新版本的AGP默认禁用了生成BuildConfig。BuildFeatures源码看到了一个配置buildConfig的注释如下。
果然如此，默认是禁用状态。在buildFeatures配置中把buildConfig值手动设为true，重新build下就好了
//开启dataBinding buildFeatures { dataBinding = true buildConfig=true }
5. Kotlin Build.gradle脚本编写（build.gradle.kts）
plugins { id("com.android.application") kotlin("android") kotlin("kapt")}android { compileSdkVersion(29) defaultConfig { applicationId = "com.xxx.xxxxx" minSdkVersion(21) targetSdkVersion(29) versionCode = 27 versionName = "2.2.0" resConfigs("zh") ndk { abiFilters += listOf("armeabi-v7a","arm64-v8a") } } //开启dataBinding buildFeatures { dataBinding = true buildConfig=true } //图片已压缩 指定aapt不做图片压缩 因为可能会反而增加图片大小 aaptOptions {// cruncherEnabled = false } //关闭lint检查 lintOptions { disable("ResourceType")// abortOnError = false } //jniLibs目录指向libs目录 sourceSets { getByName("main") { jniLibs.srcDirs("libs") } } //优化transformClassDexBuilderForDebug的时间 dexOptions { preDexLibraries = true maxProcessCount = 8 } //禁止生成依赖元数据 不上play用不到 dependenciesInfo { includeInApk = false } //jdk1.8支持 compileOptions { sourceCompatibility = JavaVersion.VERSION_1_8 targetCompatibility = JavaVersion.VERSION_1_8 } kotlinOptions { jvmTarget = JavaVersion.VERSION_1_8.toString() } //签名配置 signingConfigs { getByName("debug") { storeFile = file("../xxx.jks") storePassword = "xxx" keyAlias = "xxx" keyPassword = "xxx" } } buildTypes { getByName("debug") { //签名 signingConfig = signingConfigs.getByName("debug") //git提交次数 作为测试包版本后缀 buildConfigField("int", "GIT_COMMIT_COUNT", getGitCommitCount()) } register("alpha") { //继承debug配置 initWith(getByName("debug")) //混淆 isMinifyEnabled = true proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro") //ZipAlignEnabled优化 isZipAlignEnabled = true //移除无用的resource文件 isShrinkResources = true } getByName("release") { //继承alpha配置 initWith(getByName("alpha")) //关闭debug debuggable(false) } } //release打包时自定义apk名字、输出路径 android.applicationVariants.all { outputs.all { if (this is com.android.build.gradle.internal.api.ApkVariantOutputImpl) { this.outputFileName = "xxxx.apk" } } }}//获取git提交次数fun getGitCommitCount(): String { val os = org.apache.commons.io.output.ByteArrayOutputStream() project.exec { commandLine = "git rev-list --count HEAD".split(" ") standardOutput = os } return String(os.toByteArray()).trim()}//依赖库apply(from = "depends.gradle")
