[原]Android打包之Gradle打包

最近尝试了一下Android的Gradle打包，发现确实比Ant打包会方便很多，特此记录下来。

注：android的gradle现在插件的版本已经是0.14.3了，对于一些老的方法和api，有一些已经被移除，无法使用(http://tools.android.com/tech-docs/new-build-system/migrating-to-1-0-0)，以下这些属性改名，原先的不能用:

runProguard -> minifyEnabled (是否混淆)

zipAlign -> zipALignEnabled (是否zip对齐)

packageName -> applicationId

jniDebugBuild-> jniDebuggable

renderscriptDebug->renderscriptDebuggable

renderscriptSupportMode->renderscriptSupportModeEnabled

renderscriptNdkMode->renderscriptNdkModeEnabled

Variant.packageApplication/zipAlign/createZipAlignTask/outputFile/processResources/processManifest使用variant.out代替

1、将Eclipse project转换成Gradle project：

      在Project右键->Export->Generate Gradle build files,这样就会在Project多出一下文件：

　　

├── build.gradle

├── gradle

│   └── wrapper

│       ├── gradle-wrapper.jar

│       └── gradle-wrapper.properties

├── gradlew

├── gradlew.bat

gradlew和gradlew.bat分别是*nix下和windows下可执行的脚本，gradle-wrapper.properties用来指定需要下载的gradle的版本，内容如下：

#Wed Apr 10 15:27:10 PDT 2013

distributionBase=GRADLE_USER_HOME

distributionPath=wrapper/dists

zipStoreBase=GRADLE_USER_HOME

zipStorePath=wrapper/dists

distributionUrl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip

build.gradle是用来配置编译选项的文件，附一个能够成功运行的编译脚本：

import java.text.DateFormat

import java.text.SimpleDateFormat

import java.util.regex.Pattern



buildscript {

    repositories {

        mavenCentral()

    }

    //指定gradle插件版本

    dependencies {

        classpath 'com.android.tools.build:gradle:0.14.+'

    }

}

apply plugin: 'android'



//添加android依赖libs

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])

}



//获取系统时间

def buildTime() {

       def df = new SimpleDateFormat("yyyyMMdd'-'HHmm")

       df.setTimeZone(TimeZone.getDefault())

       return df.format(new Date())

}



def apkName = "AndroidGradle"



android {

    compileSdkVersion 18

    buildToolsVersion "20.0.0"



    sourceSets {

        main {

            manifest.srcFile 'AndroidManifest.xml'

            java.srcDirs = ['src']

            resources.srcDirs = ['src']

            aidl.srcDirs = ['src']

            renderscript.srcDirs = ['src']

            res.srcDirs = ['res']

            assets.srcDirs = ['assets']

        }



        // Move the tests to tests/java, tests/res, etc...

        instrumentTest.setRoot('tests')

    }

    

    //签名

    signingConfigs {

        release {

            storeFile file('release.keystore')

            storePassword '123456'

            keyAlias 'demo'

            keyPassword '111111'

        }

    }

    

    //渠道

    productFlavors {

        free {

            applicationId 'com.clarck.httpclientnew.free'

        }

        premium {

            applicationId 'com.clarck.httpclientnew.premium'

        }

    }

    

    //lint检查

    lintOptions {

        abortOnError false

    }

    

    buildTypes {

        release {

            //混淆开关

            minifyEnabled true

            //是否zip对齐

            zipAlignEnabled true

            //是否打开debuggable开关

            debuggable false

            //是否打开jniDebuggable开关

            jniDebuggable false

            //混淆配置文件

            proguardFiles getDefaultProguardFile('proguard-android.txt')

            //签名配置

            signingConfig signingConfigs.release

        }

        

        android.applicationVariants.all { variant ->

            def manifestFile = file("AndroidManifest.xml")

            def pattern = Pattern.compile("versionName=\"(.+)\"")

            def manifestText = manifestFile.getText()

            def matcher = pattern.matcher(manifestText)

            matcher.find()

            def versionName = matcher.group(1)            

            pattern = Pattern.compile("versionCode=\"(.+)\"")

            matcher = pattern.matcher(manifestText)

            matcher.find()

            def versionCode = matcher.group(1)            

            

            if (variant.buildType.zipAlignEnabled) {  

                variant.outputs.each { output ->  

                    def outputFile = output.outputFile  

                    if (outputFile != null && outputFile.name.endsWith('.apk')) {  

                        def fileName = "apk/" + applicationId + "-V" + versionName + "-" + versionCode + "-" + variant.name + "-" + buildTime() + ".apk"  

                        output.outputFile = new File(outputFile.parent, fileName)  

                    }  

                }  

            } else {  

                variant.outputs.each { output ->  

                    def outputFile = output.outputFile  

                    if (outputFile != null && outputFile.name.endsWith('.apk')) {  

                        def fileName = "apk/" + applicationId + "-V" + versionName + "-" + versionCode + "-" + variant.name + "-" + buildTime() + "-unaligned.apk"  

                        output.outputFile = new File(outputFile.parent, fileName)  

                    }  

                }  

            }  

        }

    }

}

 最后执行./gradlew build进行打包即可，输出如下结果就表示打包成功：
