Your aia file has a project within a project.

Did you try to import an aia as an aix file?

It needs expert surgery, or a rebuild from scratch.

hello
i just try to add AI2 MQTT Extension to my project.
i got it from this link and after that added to my project
https://ullisroboterseite.de/android-AI2-PahoMQTT.html
is it false?

Here is a clone of Screen1, without any files, extensions, or blocks.

I made it using a Designer copy of your Screen1.

Go find that MQTT .aix and import it right, then you can drag in these downloaded blocks images:




Then you can upload your Media files, and you should be hopefully all set.

The .aix file you needed was in the .zip file.

You do the .aix load in the Designer's extensions drawer.

Pass out cigars.

It's a healthy baby clone.

I extracted the .aix, loaded it, and had to add Notifier1 and pull the extension into the mock to complete the load.

Then the dragged blocks lost their red errors after a refresh.

The code server is running busy for builds at the moment.

See if you can import it and build.

Oops, I forgot the Media files, including your icon.

Can I leave that to you?

Okay, a few moments with 7zip, and your thankfully short media file list was loaded, and you build okay.
