How to resolve this AnnotationAreNotAllowedHere error in android studio while making portfolio app?

I was making portfolio app in android studio but this error is showing. Help

@Override
                protected void onActivityResult(int requestCode,int resultCode,@Nullable Intent data){
            super.onActivityResult(requestCode, resultCode, data);
            if(requestCode==REQUEST_DETAILS_CODE && resultCode==RESULT_OK && data!=null){
                Portfolio portfolio=data.getParcelableExtra(addActivity.MV_PORTFOLIO);
                if(portfolio!=null){
                    setDetails(portfolio);
                }
            }
        }```
