How to change apk package name?

Question

Android

I want to install the application over the old one, but the package name of the new apk does not match the old one, how can I quickly change the package name of the new apk, what software can I use?

Answer 1

So for sure the signature is also different, so no way

Answer 2

And what, exactly, is the problem? If the package name is different, then Android will perceive it as a different application and put it next to the old one, and the old one can be deleted. Simply renaming the file will not give the desired effect, because. the name of the package is written inside it, for example, in the application manifest.
