This is an integer and its value should be increased for each new version. So the higher the value of this integer, the more recent the version of your app is.

关于安卓移动端apk安装签名问题

由 喜欢而已 提交于 2019-12-10 05:50:57
签名 签名是什么 Android系统在安装Apk的过程中，会对Apk进行签名校验，校验通过后才能安装成功。如果想要深入理解签名的，可以自行百度查看一下。 如何获取签名 可以通过系统默认的签名进行获取，获取系统的默认签名方法 keytool -list -v -keystore debug.keystore 通过在cmd中输入这段代码即可显示获取证书指纹 自定义签名，首先也是进入到存放keystroe的文件夹中，使用签名 keytool -list -v -keystore xxx -keypass xxx xxx可以修改为自己想要的密钥 如何获取apk文件中的签名 首先apk的文件是分两种情况，一种是apk本身就没有签名，一种是打包的时候已经给签名了。这样的话想要获取apk的签名，需要以下的步骤 // 首先，需要对apk文件后序改为zip // 打开后，对要把里面的META-INF文件拿出来 // 打开cmd，进入到META-INF文件所在路径，输入以下命令 keytool -printcert -file CERT.RSA // 即可获取当前apk的签名. 获取apk文件中的包名 对于apk文件中，签名和包名都是对apk进行一个标识认证的东西 如果要获取包名，页只需要一条命令即可获取 aapt dump badging xxxx.apk xxx需要相对应的改为名称 来源：
