AndroidStudio_Gradle环境搭建

     今天配置android studio上的工程时发现没有gradle的配置，于是搜索资料学习了一下，总结内容如下：
 如何配置gradle环境 ？？？
1.从官方网站获取最新的zip包 
http://www.gradle.org/ 或者 (http://www.gradle.org/downloads)
2.将其解压并配置环境变量指向gralde目录 如 
%GRADLE_HOME%=E:\WorkProgram\gradle 
在path中设置bin目录 
%GRADLE_HOME%\bin; 
打开控制台，运行gradle -v ；配置成功

gradle -v

Gradle 1.3

Gradle build time: 2012年11月20日 星期二 上午11时37分38秒 UTC   
Groovy: 1.8.6   
Ant: Apache Ant(TM) version 1.8.4 compiled on May 22 2012   
Ivy: 2.2.0   
JVM: 1.7.0_05 (Oracle Corporation 23.1-b03)   
OS: Windows NT (unknown) 6.2 amd64   
gradle的构建脚本命名为“build.gradle”。 
首先创建一个文件：build.gradle 
在文件中加入： 
Gradle代码  收藏代码
task hello {      
doLast {  println 'Hello world!'     }   
}   
然后我们运行：gradle -q hello 
输出内容为： 
> gradle -q hello Hello world! 
解析： 
我们首先定义了一个task：hello 
在task中我们定义了一个action：doLast 
当我们执行 gradle hello 时，gradle会执行 hello task，最终会运行 doLast action

Android工程下的一个build.gradle文件内容如下：

buildscript {    repositories {        mavenCentral()    }    dependencies {        classpath 'com.android.tools.build:gradle:0.4'    }}apply plugin: 'android'dependencies {}android {    compileSdkVersion 17    buildToolsVersion "17"    defaultConfig {        minSdkVersion 8        targetSdkVersion 17    }    sourceSets {        main {            manifest.srcFile 'AndroidManifest.xml'            java.srcDirs = ['src']            resources.srcDirs = ['src']            aidl.srcDirs = ['src']            renderscript.srcDirs = ['src']            res.srcDirs = ['res']            assets.srcDirs = ['assets']        }    instrumentTest.setRoot('tests')    }}
