Qt Android activity creation problem on Java update

SevenM

Hi All,
Apparently I am trying to upgrade development environment of my existing Qt project.
Original:
Qt 5.12.9
JDK 8
Gradle 4.6

Upgraded to:
Same Qt version
JDK 11
Gradle 7.4.0

To achieve this, I updated some deprecated Manifest settings and moved them to gradle.
I am able to compile and run the application however I see a runtime error and UI goes blank. The error in logcat is as follows:

E/Qt: Can't create main activity

To be precise, it occurs on the following line in myactivity.java:

super.onCreate(savedInstanceState);

The only thing I did was upgrading environment. I am not sure if any new addition is expected with this upgrade?

Newer versions of Android are able to read native libs directly from the apk without extracting them if they are stored uncompressed in the apk.
This is done to save disk space on the device, and the new default during apk creation, but Qt 5.12 does not handle this.

To compress native libs again add android:extractNativeLibs="true" in AndroidManifest.xml to the application tag.
