Android Question Activity.LoadLayout("1") ERROR

[Yung]

Hello, I have a problem with my code, I'll tell you, I'm developing a small app to be able to turn lights on and off, televisions or any type of appliance from the cell phone, but when debugging the application it gets stuck on a line and that is: Activity.LoadLayout("1")
And I really can't find the problem, here I leave a photo with the error and if necessary I also pass the code, I would greatly appreciate any help, thank you very much in advance.

If the layout exists. User CTRL + P to clean the project and force new files copy.

You shouldn't see Activity in your code. Switch to B4XPages.

How do I do that?
