Android Question Update from b4a v10.50 to v11.00

Your description of How you've updated the required resources and Android SDK Command line tools is rather vague.
Have you extracted the ZIPs using 7-Zip?
It is essential to follow the instructions very carefully: https://www.b4x.com/b4a.html and Don't windows built-in extract (corrupts folder structure).
Usually, it's best to delete the old folder structure and re-create as per the instructions, unless you have have extensively used SDK manager for features your App(s) need, beyond the core B4A needs.

Please post the full text from the compilation window.

I extracted the zip files with 7zip and copied them to the newly created Android folder. Renewed the setting of the paths. But the result is the same.

In the original source project created with v10.50 the folder ".../(b4aProjectname) Dateiler/Objects/gen/" is always empty. But now folders are missing here...

Might be related to an over-aggressive anti virus.

... anti-virus ... I will look into this

But which files and folders should be included in "Objects/gen" ?

This folder is created automatically during compilation. It includes some of the generated files.

My experience. I did not use 7-zip going from 9.something to 11.0 and had very unusual results. Files appeared to be in place but b4a said they were missing during run/compile. Reinstalled using 7-zip and all was correct when performing run/compile. Thank you Erel and all who participated in this post. Take away, when Erel says to specifically do or use something concerning b4a take the advise. Now if I could only learn to take direction from my wife I'd truly be a happy man, she also is usually correct.
