最近一直在做android自动打包,之前已经完成了用纯命令行的形式打包、原生态ant脚本打包,和基于android的SDK的打包,并且实现了多渠道打包,后来同事推荐了gradle,网上的资料说gradle各种好,自己也感兴趣是实现一下,其实一般来说由于android对eclipse的支持减弱,大部分的人都是用gradle与android studio融合,这样面的例子也会比较多,但笔者所在的项目还是在eclipse的比较多,由于开发人员在移植过程中发现报错比较多所以一直没有完全移植(好吧,其实早晚会移植),所以笔者是用eclipse的IDE做的实验,下面先贴几个基础知识
首先是新建一个android项目,然后用自带的IDE生成gradle文件,具体参考http://blog.csdn.net/x605940745/article/details/41242687,有兴趣的同志们可以采取纯手写的方式,这种方式可以不依赖IDE,所以会比较好
这个是原始的build.gradle
buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.8.+' } } apply plugin: 'android' dependencies { compile fileTree(dir: 'libs', include: '*.jar') } android { compileSdkVersion 19 buildToolsVersion "19.0.3" 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') // Move the build types to build-types/<type> // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ... // This moves them out of them default location under src/<type>/... which would // conflict with src/ being used by the main source set. // Adding new build types or product flavors should be accompanied // by a similar customization. debug.setRoot('build-types/debug') release.setRoot('build-types/release') } }
下面我先附上自己的build.gradle
buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.12.+' } } apply plugin: 'android' ant.importBuild 'build.xml' //这里导入了ant的脚本 dependencies { compile fileTree(dir: 'libs', include: '*.jar') } android { compileSdkVersion 19 buildToolsVersion "20.0.0" signingConfigs { //签名,这里的文件名和密码是错的,后面还会有从外部导入的语句 myConfig { //绝对路径和相对路径都可以 storeFile file("E:\\keystore\\mydemo.keystore") //签名文件 storePassword "276021750" //密码 keyAlias "mydemo.keystore" keyPassword "111" } } buildTypes{ release { //这里就是用来生成apk的步骤,具体看备注 //1.添加签名 signingConfig signingConfigs.myConfig //2.runProguard 执行混淆代码 runProguard true //混淆规则文件 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt' } } productFlavors { //这里是多渠道的地方,AndroidManifest.xml文件里面要有标示,下面会贴文件 yingyongbao { manifestPlaceholders = [ CHANNEL_NAME:"YINGYONGBAO"] } umeng { manifestPlaceholders = [ CHANNEL_NAME:"UMENG" ] } wandoujia { manifestPlaceholders = [ CHANNEL_NAME:"WANDOUJIA" ] } } allprojects { //在这里是外部导入文件,然后更改本身文件的属性,这里只改了签名,还可以改其他的 afterEvaluate { project -> def propsFile = rootProject.file('E:\\keystore\\keystore.properties') def configName = 'myConfig' if (propsFile.exists() && android.signingConfigs.hasProperty(configName)) { def props = new Properties() props.load(new FileInputStream(propsFile)) android.signingConfigs[configName].storeFile = file(props['storeFile']) android.signingConfigs[configName].storePassword = props['storePassword'] android.signingConfigs[configName].keyAlias = props['keyAlias'] android.signingConfigs[configName].keyPassword = props['keyPassword'] } } } 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') // Move the build types to build-types/<type> // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ... // This moves them out of them default location under src/<type>/... which would // conflict with src/ being used by the main source set. // Adding new build types or product flavors should be accompanied // by a similar customization. debug.setRoot('build-types/debug') release.setRoot('build-types/release') } }这里的具体功能看备注就可以了,暴力的贴上去就没问题,下面要贴几个文件,一个是AndroidManifest.xml文件,里面就是加了一行
<meta-data android:name="UMENG_CHANNEL" android:value="${CHANNEL_NAME}" />build.xml添加了一个target,用cmd命令写gradle deploy就可以执行里面的内容了
<target name="deploy"> <!-- <replaceregexp flags="g" byline="true"> <regexp pattern="public static final Host host = Host.Development;" /> substitution expression 中是替换的值,替换的值都定义在相对应的配置文件中 <substitution expression="public static final Host host = Host.Test;" /> fileset 属性中的 dir 用来指定被替换文件所在的目录 includes 用来指定要替换哪个文件。 <fileset dir="./src/net/xtion/crm/base" includes="CrmAppContext.java" /> </replaceregexp> --> <replace encoding="utf-8" dir="./src/com/example/learn723"> <include name="MainActivity.java" /> <replacefilter token="public static final String host = "Host.Test";" value="public static final String host = "Host.abc";" /> </replace> </target>还有一个签名文件
storeFile=E:\\keystore\\mydemo.keystore storePassword=276021750 keyPassword=276021750 keyAlias=mydemo.keystore

这样的好处我们可以看到,用ant专职改文件的信息,这里专门做多渠道的打包,可以分开,其实要做到全自动还有两步,一个是从svn自动获取,这个网上有很多的版本可以学习,另一个是用脚本修改build.gradle文件,动态变换签名(其实也可以做批量修改)和动态增加这些功能的代码,可以用shell,可以用python,各位用需要可以试一下
