'this@ActivityName' is not captured error Android/Kotlin

I'm repairing my friend's code and got confused.
My friend wants to fetch entered text (in EditText). Seems easy, right? Well, it is but instead of user input, he gets this warning/error:

To be honest I'm not sure how to fix it. He is coding in Kotlin (Android 10).
Activity that contains EditText:

And XML:

This is how it looks when debugging:

**The app started working just fine after running "File -> invalidate Cashes/Restart" option**, I just don't understand where this warning came from and how to fix it because the error remained unchanged (even though the app works). Do you have an idea how to solve it?

All the best!

sometimes there will be problem in auto generated binding files, if so it will be solved after invalidate cache and restart ide. sometimes the warning/error show but the project and complied without errors. so no need to worry about that. for next time post the code as code not screen shots.

fyi lambda expression like setOnClickListener from kotlin is not debuggable, see [here][1].

if you want to debug variables inside setOnClickListener you should use the normal one e.g. setOnClickListener(object: View.OnClickListener {..})

I understand that the question is regarding evaluating expression, but there is a way you can read variables from your debugger console, even if you're inside an anonymous callback. I found it helpful sometimes. Here are the steps:

- First enter debugger mode inside of your anonymous callback,
- In your debugger console, look at the right side for **"Frames"**
- Within **Frames** under [![main][1]][1], you'll see stack of function execution first top one on the list is the latest: [![enter image description here][2]][2]
- Click on row(s) below the latest function, until you find an instance of your activity **AddInformationActivity**. You will see the activity instance on the right side window under **Variables**. Don't go as far as selecting functions browned out, because those are from internal libraries.
- When you see you AddInformationActivity instance, you can expand it and see its variables.

Hope that helps!
