Android IDE (AIDE) Support Forum

Code validating but not displaying

I am new to writting or android but not new to programming.
I am trying to use the AIDE app but it seems to have a contradictory effect.
I am attempting to go through the turotial and it is having an issue with adding text via a string in a textview element.
android:text=@string/hi_text
it error checks fine but when ran it give the error
Cannot view the layout. Attemp to invoke the method 'java.lang.object.java.util.map.get(java.lang.Object) on a null object reference.
The AIDE app congratulated me and wants to go to the next step in the lesson. there is an error somewhere and I think it may be with the AIDE app itself or to do with an issue with a newer version of android not liking the methodology. I am on the current version of AIDE, Android 13 and using a Fold4.

any suggestions on how to correct this?
