如何设置 gradle 和 android studio 来进行发布构建?

问题描述

我想构建 android 应用程序并开始对其进行签名.为此，我需要发布版本的 apk.Google 文档仅建议使用 Eclipse 和 ant 方式进行发布构建:http://developer.android.com/tools/publishing/app-signing.html#releasecompile

I want to build android app and start signing it. For that I need to have Release version of apk. Google documentation suggests only Eclipse and ant ways to have release builds: http://developer.android.com/tools/publishing/app-signing.html#releasecompile

但是我找不到如何强制 gradle build release 版本的 apk.build.gradle 也没有给出任何提示.gradlew tasks 提示，没有 install Release 配置，但存在卸载 release:

However I cannot find how to force gradle build release version of apk. build.gradle does not give any hints either. gradlew tasks suggests, that there is no install Release configuration, but uninstall release exists:

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
    }
}

我错过了什么?

推荐答案

在最新版的android studio中，你可以这样做:

in the latest version of android studio, you can just do:

./gradlew assembleRelease

或 aR 简称.这将产生一个未签名的发布 apk.构建一个签名的 apk 可以类似地完成，或者您可以在 Android Studio 中使用 Build -> Generate Signed Apk.

or aR for short. This will produce an unsigned release apk. Building a signed apk can be done similarly or you can use Build -> Generate Signed Apk in Android Studio.

这是我的 build.gradle 供参考:

Here is my build.gradle for reference:

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 {

    }
}
