How to set an arbitrary package name for App Inventor app ?
Example com.peppe.app123
The easiest way is to use this offline version: https://sourceforge.net/projects/ai2offline/
The package name will then look like this (in my case):
com.bodymindpower.appName
However, you should still wait for the nb185 release.

Thank you very much for the advice
Actually this is also a pre-wired "com."
To have a truly customized package name perhaps the previous procedure is better
Yes, the packageName always starts with "com.".
However, changing the packageName after decompiling the APK is not that easy. You have to be very careful because if even the slightest mistake happens, the app will not work or it will crash.
Hello Dears , i need some help from you related to while im going to upload APK file for new release for an application already in production months ago ,i have this message "Your APK or Android App Bundle needs to have the package name com.test.SphinxGlassMaintenanceTeam."

If your app is already released on Play store, you can't change package name.
I really Don want to change the package name but I have this message I don't know why?? (your APK or android app Bundle needs to have the package name Com. Test. Sssss 
did you use another builder to build your app? probably an offline server?
The package names of MIT App Inventor apps always look like this
appinventor.ai_<LOGINNAME>.<PROJECTNAME>

Hi, is there a chance that using this offline version some functions of the app could be lost? Something changed with the nb185 release?
Thanks
the latest release there is nb187b, see also AI2Offline - Browse Files at SourceForge.net
just test before uploading to Google Play...
and especially for working with an offline version remember to backup regularly... see also MIT App Inventor 2 Tips – TWO DOG APPS

Oh great, I didn't notice, I downloaded it some months ago.
Okay thank you Taifun! I'll give it a try.
I have multiple compile errors.
After what was tried? What are you talking about?
what about providing more information?

I have the same problem as the original one from this post. I'm trying to upload a new version of my app to Google Play Console after having exported it from AppInventor as an aab file. It keeps telling me :
Your APK or Android App Bundle needs to have the package name - with a convoluted package name that I don't think I ever used when I first uploaded an apk to Google Play a while back. When I change the file name to that suggested it tells me "invalid file type." I'm thinking that there must be somewhere in AppInventor where I need to change a package name field.
I tried uploading both aab and then apk, both failed with the same error message
I was using the online version of AppInventor and thinking that the aab that it exports would upload directly to Google Play. Is it going to be necessary to decompile it, rename it etc etc to get it to work? Am I going to have to use an offline version of AppInventor?
To be quite clear about the post I was referring to, which show the problem I have, it is this one :
