gradle打包android (实现外部导入签名文件、多渠道打包、导入ant脚本)

       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

代码语言:javascript复制
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

代码语言:javascript复制
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

代码语言:javascript复制
 <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

代码语言:javascript复制
	<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

代码语言:javascript复制
storeFile=E:\keystore\mydemo.keystore
storePassword=276021750
keyPassword=276021750
keyAlias=mydemo.keystore

具体demo可以在这下载

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
