Hmm. Annotations. Probably you need to import Jetbrains Annotations jar files.

Those annotations are part of the androidx.annotations package. Did you import them at the top of your Java file?


Hello! Why did you add aia? Log out, and the extension is gone at the next login

What aia? Which aia are you talking about?


Hello! Sorry, add aix extension, and aix extension will disappear when you quit app inventor. I have learned it now. Thank you!

Not true. From whom did you get to know this?

This topic is about an issue when building your App Inventor, not about the projects.
