Android APP为什么旧版本升级和新版本全新安装两者的界面等不一样？

Question

发现旧版本APP内升级和新版本APP全新安装两者装完进入APP，界面、功能等都有部分差别，可是关于里看版本号都是一样的，去APP商店也都提示是最新版，这是为什么呢？难道版本号一致，升级的APK和全新下载的APK还有差别？

Answer 1

The version of Android APP is divided into package name and version code. The package name is something like x.y.
z, and the version code is an integer.

In your case, it should be that the version code has been updated, but the package name has not been updated.

After looking at the problem carefully: it should be different apk with the same version number
