创建签名证书所使用的keystore

执行命令：keytool -genkey -alias release_v2_private_key -keypass liumiao -keyalg RSA -keysize 2048 -validity 25 -keystore keystoreByKeytool.jks -storepass liumiao

liumiaocn:Demo liumiao$ keytool -genkey -alias release_v2_private_key -keypass liumiao -keyalg RSA -keysize 2048 -validity 25 -keystore keystoreByKeytool.jks -storepass liumiaoWhat is your first and last name?

使用此keystore创建证书

选择Build菜单的Generate Signed Bundle / APK…菜单选项

结果确认

生成的apk结果文件确认

liumiaocn:Demo liumiao$ ls -l release/total 3808-rw-r--r--  1 liumiao  staff  1945533 Dec 18 20:13 app-release.apk-rw-r--r--  1 liumiao  staff      234 Dec 18 20:13 output.jsonliumiaocn:Demo liumiao$

APK文件分析结果

安装模拟器安装验证

上述APK在网易MUMU安卓模拟器上成功安装

总结

不使用Android Studio本身的界面创建keystore，直接使用keytool创建，验证结果也是一样的，所以只需要提供符合keystore格式的签名文件即可满足Android的APK文件构建需要。
