When pressing the update button, it's able to get the text from the file, but I get the runtime error "invoke: no method named `AddItems' in class com.google.appinventor.components.runtime.ListView".
How can I fix this?

That AddItems block is new to me.

The usual way is to set ListView1.Elements to split (text, '\n')

This fixed it! Thanks.

It would be nice to finally update the Companion...
