Welcome back,
I have not yet updated Android SDK + Required Resources, so far I could compile all applications on old sources without major problems.
When I update the Android SDK, I will let you know if it helped.
Thanks to everyone for now.
Hi,
It seems the Android SDK update helped. And I admit it works on both Java 8 and 11, although I prefer to work on Java 8. Moreover, everything works for me regardless of the JDK 1.8.0.251 or JDK 1.8.0.291
Also, the case seems to be closed
Thanks to everyone for your help.
