How do I fix “There Was a Problem Parsing the Package”?

[Alexandre_Gorine]

The problem with one of my apps disappeared after upgrading TaifunAlarmManager to version 5c!!!
Thanks a lot!
But unfortunately 2 of my other apps keep giving the same error even after upgrading TaifunAlarmManger. But with a high degree of probability they have a similar problem with another extension that has not been upgrated. I will compare the list of extensions and try to determine the culprit and share it here

Another extension that needs to be updated is ITOO ItoO - Background Tasks [special] 🥳 (but I haven't found an update yet and just deleted it from the project)
SUMMARY: By upgrading TaifunAlarmManager to the version 5c and removing the ITOO extension, the problem was solved!
THANK YOU VERY MUCH!

By upgrading TaifunAlarmManager to the version 5c and removing the ITOO extension, the problem was solved!

Is that actually the solution?
I don't think so because the affected extensions must update them to fix the problem on Android 12+.

Android 12 changes

Anyone facing this problem after targetSdk 31 when using extensions has two options: Contact the extension developer(s) and ask them to declare this (android:exported="true" for activities, broadcast receivers) in the Manifest. Build the APK, decompile it, declare it in the Manifest, recompile the APK, convert the APK to AAB and sign it.
