Android Question Exception Resource ID # 0x7f030016 when using the adaptive icon x appcompat [Solved]

[Livio F]

The project is with APPCOMPAT.
After including the icon adaptive to the project in the manifest, it stopped working.
I searched the forum, but I found nothing.

Did you make the icon read-only?

Yes, I did.

Your project works fine here. Are you using an updated Android SDK: https://www.b4x.com/b4a.html ?

Erel, thank you.

I did the procedure again and it worked.
