请注意，我们已经在Android SDK的帮助下通过命令行创建了一个apk文件.现在，由于将其上传到Google Play商店，因此需要对apk进行签名.我们该怎么做.

Be informed that we have created an apk file through command line with the help of Android SDK. Now since uploading it to google play store needs the apk to be signed. How shall we do this.

推荐答案

步骤1

首先，您需要生成一个私人签名密钥

Step 1

First you need to generate a private signing key

keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

此命令将提示您输入密钥库和密钥的密码(也用于某些其他字段).请记住，随时将您的密钥库文件保留为私有.

This command will prompt you for a password for your keystore and key (also for some additional fields). Please remember to keep your keystore file private at anytime.

接下来，您需要设置gradle

Next you need to setup gradle

1. 将您在步骤1中生成的my-release-key.keystore放置在android/app
下

2. 在android/app下更新您的~/.gradle/gradle.properties并添加以下内容

1. Place my-release-key.keystore which you generated in Step 1 under android/app

2. Update your ~/.gradle/gradle.properties under android/app and add the following

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=<The password you choose earlier with the keytool>
MYAPP_RELEASE_KEY_PASSWORD=<The password you choose earlier with the keytool>

步骤3

最后，您需要更新您的android/app/build.gradle.

android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}

现在，您只需在Android目录中运行以下命令，即可通过命令行生成一个已签名的发行版

Now you can simply generate a signed release via the command line by running the following command in your android directory

./gradlew assembleRelease

然后可以在您的build/outputs/apk/release目录下找到生成的apk.

The generated apk can then be found under your build/outputs/apk/release directory.
