Android Studio中创建keystore

Build -> Generate Signed APK -> Create New

最后的扩展名为jks

在build.gradle中添加配置

signingConfigs {
        debug {
            keyAlias 'your-keyAlias'
            keyPassword 'your-keyPassword'
            storeFile file("keystore-release.jks")
            storePassword 'your-storePassword'
        }
    }
