我想有我的Gradle构建创建一个发布签名apk文件使用Gradle。

我不确定代码是否正确,或者我在做gradle构建时是否缺少一个参数?

这是build.gradle/build.gradle中的一些代码。节文件:

android {
    ...
    signingConfigs {
        release {
            storeFile(file("release.keystore"))
            storePassword("******")
            keyAlias("******")
            keyPassword("******")
        }
    }
}

Gradle构建成功完成,在我的build/apk文件夹中,我只看到…-release-unsigned.apk和…-debug-unaligned.apk文件。

对如何解决这个问题有什么建议吗?

我设法解决它添加这段代码,并与gradle构建:

android {
    ...
    signingConfigs {
        release {
            storeFile file("release.keystore")
            storePassword "******"
            keyAlias "******"
            keyPassword "******"
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

这将生成一个已签名的发布apk文件。

注意@sdqali的脚本会(至少在使用Gradle 1.6时)要求输入密码 任何时候调用gradle任务。因为你只在做gradle assemblerrelease(或类似)时需要它,你可以使用下面的技巧:

android {
    ...
    signingConfigs {
        release {
            // We can leave these in environment variables
            storeFile file(System.getenv("KEYSTORE"))
            keyAlias System.getenv("KEY_ALIAS")

            // These two lines make gradle believe that the signingConfigs
            // section is complete. Without them, tasks like installRelease
            // will not be available!
            storePassword "notYourRealPassword"
            keyPassword "notYourRealPassword"
        }
    }
    ...
}

task askForPasswords << {
    // Must create String because System.readPassword() returns char[]
    // (and assigning that below fails silently)
    def storePw = new String(System.console().readPassword("Keystore password: "))
    def keyPw  = new String(System.console().readPassword("Key password: "))

    android.signingConfigs.release.storePassword = storePw
    android.signingConfigs.release.keyPassword = keyPw
}

tasks.whenTaskAdded { theTask -> 
    if (theTask.name.equals("packageRelease")) {
        theTask.dependsOn "askForPasswords"
    }
}

注意,我还必须添加以下(在android下)使其工作:

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}

就像@Destil说的,但允许其他没有钥匙的人建造: 比之前的答案更简单的方法:

把它放到~/.gradle/gradle.properties中

RELEASE_STORE_FILE={path to your keystore}
RELEASE_STORE_PASSWORD=*****
RELEASE_KEY_ALIAS=*****
RELEASE_KEY_PASSWORD=*****

修改构建。这样Gradle:

...    
if(project.hasProperty("RELEASE_STORE_FILE")) {
    signingConfigs {    
       release {
           storeFile file(RELEASE_STORE_FILE)
           storePassword RELEASE_STORE_PASSWORD
           keyAlias RELEASE_KEY_ALIAS
           keyPassword RELEASE_KEY_PASSWORD
       }
    }
}

buildTypes {
    if(project.hasProperty("RELEASE_STORE_FILE")) {
        release {
            signingConfig signingConfigs.release
        }
    }
}
....

然后你可以运行gradle assemblerrelease 或 gradle构建

这是对user672009的回复,也是对sdqali的帖子的补充(他的代码会在IDE的“Run”按钮构建调试版本时崩溃):

您可以使用以下代码:

final Console console = System.console();
if (console != null) {

    // Building from console 
    signingConfigs {
        release {
            storeFile file(console.readLine("Enter keystore path: "))
            storePassword console.readLine("Enter keystore password: ")
            keyAlias console.readLine("Enter alias key: ")
            keyPassword console.readLine("Enter key password: ")
        }
    }

} else {

    // Building from IDE's "Run" button
    signingConfigs {
        release {

        }
    }

}

另一种方法是定义一个只在发行版上运行的任务。

android {
  ...
  signingConfigs {
     release {
        // We can leave these in environment variables
        storeFile file('nameOfKeystore.keystore')
        keyAlias 'nameOfKeyAlias'

        // These two lines make gradle believe that the signingConfigs
        // section is complete. Without them, tasks like installRelease
        // will not be available!
        storePassword "notYourRealPassword"
        keyPassword "notYourRealPassword"

     }
  }
  buildTypes {
     ...
     release {
        signingConfig signingConfigs.release
        ...
     }
  }
  ...
}

task setupKeystore << {
final Console console = System.console();
if (console != null) {
    //def keyFile = console.readLine(“\nProject: “ + project.name + “Enter keystore path: "))
    //def keyAlias = console.readLine(“Project: “ + project.name + “Enter key alias: ")
        def storePw = new String(console.readPassword(“Project: “ + project.name + “. Enter keystore password: "))
        def keyPw  = new String(console.readPassword(“Project: “ + project.name + “.Enter keystore password: "))

    //android.signingConfigs.release.storeFile = file(keyFile);
    //android.signingConfigs.release.keyAlias = keyAlias
        android.signingConfigs.release.storePassword = storePw
        android.signingConfigs.release.keyPassword = keyPw
}
}

//Validate t
def isReleaseConfig = gradle.startParameter.taskNames.any {it.contains('Release') }
if (isReleaseConfig) {
    setupKeystore.execute();
}

在更新的Android Studio中,有一种非常简单的GUI方式,它也可以填充Gradle文件。

File ->项目结构 选择主模块('app'或其他自定义名称) 签名选项卡-> +图像添加新的配置 在右侧填写数据 然后自动创建Gradle文件 您必须手动添加一行signingConfig signingConfig。builtTypes{release{}}中的yourconfig名称

两个重要的(!)注意事项:

(12/15)编辑

要创建签名APK,你必须打开Android Studio的Terminal选项卡(主界面的底部)并发出命令。/gradlew assemblerrelease 如果你忘记了keyAlias(经常发生在我身上),你将不得不启动Build -> Generate Signed APK来启动这个过程,并看到别名密钥的名称。
