Changing the package name of an Android app

I want to change the package name of an app so that it can be installed side-by-side with the original version. Changing the package name in AndroidManifest.xml causes the app to crash on startup.

As I got stuck on this (I’m not very experienced), I would like to pay someone to help me get past this issue.

Here is the error I’m getting when launching the app after changing its package name:

Process crashed: java.lang.ClassNotFoundException: androidx.core.app.j

Lucky Patcher didn’t help?

is payment in crypto an option?

I accept transaction only if i’m able to complete the job. Upload the apk so i can test it out.

I didn’t try this one but no automatic tool worked so far…

I never used crypto before but sure, I suppose it’s not a big deal to set it up. I have the username on Telegram as here, let’s talk in private.

Budget is 500€, anyone interested in this?

I’m interested to help also, can you upload the APK somewhere to test?
My telegram account is @AbkarinoMHM.

I wrote in private, thank you

This is still open, anybody else?

I will help you please PM me

Done, I sent you the PM
