android gradle的常见配置_android gradle配置

1.build.gradle 常见设置

//依赖其他gradle文件
apply from: "config.gradle"
 
plugins {
    //添加使用插件
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-kapt'
}
 
example = “this is a test message”
 
android {
    compileSdkVersion 30
 
    //冲突文件处理
    packagingOptions {
        //jar or aar or .so ... ,如有冲突依次优先使用
        pickFirst 'lib/arm64-v8a/test_shared.so'
        pickFirst 'lib/x86/test_shared.so'
        pickFirst '**/test_shared.so' //匹配任意路径
 
        //合并处理
        merge ''
       
        //直接排除
        exclude ''
    }
 
    defaultConfig {
        
        //设置支持的手机架构
        ndk {
            abiFilters 'armeabi-v7a'
        }
        
        //设置java编译的一些参数
        javaCompileOptions {
            annotationProcessorOptions {
                
            }
        }
 
        //cmake 命令参数
        externalNativeBuild {
            cmake {
                // explicitly build libs
                targets 'mind'
                abiFilters "armeabi-v7a" // 编译出的so库要支持的手机架构
                cppFlags "-std=c++11 -fexceptions -frtti"
                arguments "-DMY_NAME=ZHOU" //注意：-D是命令，后面是参数的key-value，向cmakeLists传参
            }
 
        }
 
        //dex 分包
        multiDexEnabled true
    }
 
    signingConfigs {
        release {
            storeFile file("../keystore/test.keystore")
            keyAlias "test"
            storePassword "test!"
            keyPassword "test!"
            v1SigningEnabled true
            v2SigningEnabled true
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            // 可将gradle中的常量编译到BuildConfig.java,在java代码中使用如:BuildConfig.APP_EXAMPLE
            buildConfigField "String", "APP_EXAMPLE", "\"${example}\""
        }
        debug {
            signingConfig signingConfigs.debug
            buildConfigField "String", "APP_EXAMPLE", "\"${example}\""
        }
    }
 
    //开启viewBinding 和 dataBinding
    buildFeatures {
        viewBinding = true
        dataBinding = true
    }
 
    //设置java版本
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
 
    //设置kotlin版本
    kotlinOptions {
        jvmTarget = '1.8'
    }
 
//c层编译参数设置
externalNativeBuild {
            cmake {
                version '3.6.0'  //cmake版本
                path 'src/main/cpp/CMakeLists.txt'  //cmake编译文件的路径
            }
 
        }
 
    //源文件路径设置
    sourceSets {
        main {
            def javaPaths = ["src/main/java"]
            def assetsPaths = ["src/main/assets"]
 
            def javaPanda = "src/main/javaPanda"
            def javaLoin = "src/main/javaLoin"
            def javaMonkey = "src/main/javaMonkey"
 
            //根据条件加入源文件
            if ( true ) { 
                javaPaths.add(javaPanda)
            }
            if (true) {
                javaPaths.add(javaLoin)
            }
            if (true) {
                javaPaths.add(javaMonkey)
            }
            java.srcDirs = javaPaths
            assets.srcDirs = assetsPaths
 
           //设置AndroidManifest.xml的路径，在组件化中经常用到
           manifest.srcFile(gradle.ext.isGroup != true ? 'src/main/demo/AndroidManifest.xml' : 'src/main/AndroidManifest.xml')
        }
 
        //设置so库的路径，不然的话so库不会打进包里
        debug {
            jniLibs.srcDirs = ['libs']
        }
        release {
            jniLibs.srcDirs = ['libs']
        }
        
    }
}
 
//清除编译生成的缓存文件
task cleanFiles(type: Delete) {
    delete file("./build")
    delete file("./.externalNativeBuild")
}
 
//自定义任务
task buildAStart() {
    //之前此任务前先执行cleanFiles
    dependsOn cleanFiles
    //上面任务执行完后执行
    doLast {
        exec {
            println("buildAStart")
            workingDir "../../"  //脚本文件路径
            commandLine 'sh', 'build_start.sh' //执行脚本文件
            args('-t',tags)  //向执行脚本传参,如：脚本需要此参数进行操作
        }
    }
}
 
//执行此gradle的构建任务之前先执行buildAStart任务
preBuild.dependsOn(buildAStart)

2. Setting.gradle

//全局（扩展）常量，在其他gradle文件中也能拿到，使用时：$gradle.testValue 
gradle.ext.testValue = true
gradle.ext.testHello = 'Hello'
gradle.ext.testInt = 1
//相对于setting.gradle的路径，此为该路径下的一个module
gradle.ext.mFilePath = '../Example/mine/demo1/app'
 
//局部变量
def max = 5
 
def file = new File(gradle.ext.mFilePath)
if (file.exists()) {
    include ':other-module' //引入一个名为other-module的module
    rootProject.name = 'myDemo' //设置根工程名称
    project(':other-module').projectDir = file  //关联other-module这个module的工程路径
}

3.自定义gradle，如config.gradle,将常用的配置抽取出来统一管理，在其他build.gradle中调用如：

rootProject.ext.android.targetSdkVersion

ext{
    android = [
            compileSdkVersion: 30,
            buildToolsVersion: '30.0.2',
            minSdkVersion    : 19,
            targetSdkVersion : 26,
            applicationId    : "com.zz.example.testDemo",
            versionCode      : 1,
            versionName      : "1.0",
    ]
    //androidx支持库配置
    androidx = [
            "androidx.appcompat"                  : "androidx.appcompat:appcompat:1.1.0",
            "androidx.lifecycle"                  : "androidx.lifecycle:lifecycle-extensions:2.1.0",
            "androidx.recyclerview"               : "androidx.recyclerview:recyclerview:1.1.0",
            "androidx.constraintlayout"           : "androidx.constraintlayout:constraintlayout:1.1.3",
            "androidx.cardview"                   : "androidx.cardview:cardview:1.0.0",
            "android.material"                    : "com.google.android.material:material:1.0.0",
            "androidx.navigation-fragment"        : "androidx.navigation:navigation-fragment:2.1.0",
    ]
 
    //依赖第三方配置
    dependencies = [
            "arouter-compiler"             : "com.alibaba:arouter-compiler:1.5.1",
            "smartRefresh"                 : "com.scwang.smartrefresh:SmartRefreshLayout:1.1.2",
            "eventbus"                     : "org.greenrobot:eventbus:3.2.0",
            "imagepicker"                  : "com.github.HuanTanSheng:EasyPhotos:3.0.6",
           "immersionbar"                 : "com.gyf.immersionbar:immersionbar:3.0.0", //状态栏库
            "permissionx"                  : "com.permissionx.guolindev:permissionx:1.4.0",
            "rxbinding"                    : "com.jakewharton.rxbinding4:rxbinding:4.0.0",
            "okhttp"                       : "com.squareup.okhttp3:okhttp:4.9.0"
    ]
}
