android content resource$not found exception stringresource id

I think you have an error in your xml (well, using undefined string resource, I guess)

The call to setText() is expecting a string resource id. Specifically, radiobutton.setText(i) is interpreting 'i' to be a string resource id vs. the index you are passing in.
