如何设置gradle和android studio做发布构建？

我想构建android应用并开始对其进行签名。为此，我需要发布apk的发行版。Google文档仅建议使用Eclipse和蚂蚁发布版本的方法：http : //developer.android.com/tools/publishing/app-signing.html#releasecompile

但是我找不到如何强制gradle build发行版本的apk。build.gradle也没有给出任何提示。gradlew tasks建议没有安装发布版本的配置，但存在卸载版本：

Install tasks
-------------
installDebug - Installs the Debug build
installTest - Installs the Test build for the Debug build
uninstallAll - Uninstall all applications.
uninstallDebug - Uninstalls the Debug build
uninstallRelease - Uninstalls the Release build
uninstallTest - Uninstalls the Test build for the Debug build

我的build.gradle：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
    compile files('libs/android-support-v4.jar')
    compile project(":libraries:ActionBarSherlock")
    compile project(":libraries:CollabsibleSearchMenu")
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 16
    }
}

我缺少什么？

在最新版本的android studio中，您可以执行以下操作：

./gradlew assembleRelease

或aR简称。这将产生一个未签名的发布apk。构建签名的apk可以类似地完成，也可以在Android Studio中使用Build-> Generate Signed Apk。

这是我的build.gradle供参考：

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:0.5.+'
  }
}
apply plugin: 'android'

dependencies {
  compile fileTree(dir: 'libs', include: '*.jar')
}

android {
compileSdkVersion 17
buildToolsVersion "17.0.0"

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')

    // 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')

}

buildTypes {
    release {

    }
}
