图文来教你在eclipse下用gradle 来打包Android

gradle其他好处就不多说，在android应用发布的时候，如果要统计多个渠道，gradle 批量打包的好处就显示出来了；下面介绍图文来介绍

按eclipse的导出时 选择Android；如下图 然后按下面一步一步往下点

点击完成之后 工程里面就生成了如下的几个文件；也就是gradle的配置文件

打开gradle-wrapper.properties这个文件；可以看到distributionUrl这个地址；而这个地址就是gradle的下载地址；在浏览器打开下载 如下图：

将下载的文件押解出来；然后需要设置系统环境变量；需要设置变量名：GRADLE_HOME变量值为:C:\xiong\gradle-1.10-all\gradle-1.10（也就是你下载的Gradle文件的根目录）然后设置path；在后面加上C:\xiong\gradle-1.10-all\gradle-1.10\bin 如下图

然后运行在cmd中运行gradle -v来判断是否设置成功 如下图

确定安装成功之后就基本可以运行gradle命令来打包了；将cmd命令定位到工程的根目录，然后运行gradle bulid

如下图

如果需要批量打包；则在build.gradle进行配置

原始eclipse生成的文件内容如下

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')
    }
}

只要在如上代码中添加就可以  比如

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')
            //批量打包--指定配置文件
        //不同的渠道商对应的各自AndroidManifest
        //AndroidManifest的application标签只用配置渠道号的值
        //其他公共配置都放在公共的AndroidManifest.xml中
        one {
       manifest.srcFile 'tests/AndroidManifest1.xml'
    }
    two {
       manifest.srcFile 'tests/AndroidManifest2.xml'
    }
        instrumentTest.setRoot('tests')  

    }

     //批量打包--声明
    productFlavors {
    one {
            //这里可以配置不同的包名
    }
    two {
    }
    }
      //签名
    signingConfigs {
      myConfig {
          storeFile file("11.keystore")      //签名文件
          storePassword "111111"
          keyAlias "111111"
          keyPassword "111111"  //签名密码
      }
    }
}

如下图

至于其他的 俺就不说了 不动找度娘
