How does Android get the file name of apk when it is installed?

want to carry user or channel source information through the apk file name, but after many programs are installed, the installation package will be deleted. I don"t know how to solve it.

cannot do so, android will not retain the installation package file name information.


first of all, this method is not feasible;
second, who is this information left to?


different channels use different installation packages, all of which do so
