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
    }
}

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。

我在Ubuntu14.04工作。 vim ~ /。Bashrc和add 出口ANDROID_KEYSTORE = 出口ANDROID_KEYALIAS =

然后是构建。它集。

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

    // Building from console
    signingConfigs {
        release {
            storeFile file(System.getenv("KEYSTORE"))
            storePassword new String(System.console().readPassword("\n\$ Enter keystore password: "))
            keyAlias System.getenv("KEY_ALIAS")
            keyPassword new String(System.console().readPassword("\n\$ Enter key password: "))
        }
    }

} else {

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

        }
    }

}

在React-Native中使用React-Native -config包添加我的方法。 创建一个.env文件:

RELEASE_STORE_PASSWORD=[YOUR_PASSWORD]
RELEASE_KEY_PASSWORD=[YOUR_PASSWORD]

注意，这不应该是版本控制的一部分。

在你的build.gradle中:

signingConfigs {
        debug {
            ...
        }
        release {
            storeFile file(RELEASE_STORE_FILE)
            storePassword project.env.get('RELEASE_STORE_PASSWORD')
            keyAlias RELEASE_KEY_ALIAS
            keyPassword project.env.get('RELEASE_KEY_PASSWORD')
        }
    }

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();
}

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 {

        }
    }

}
