What am I doing wrong?

So I'm working on the Initialize get answer button code challenge on the Android App development course, and I can't figure out what I did wrong.

TextView answerLabel = (TextView) findViewById(R.id.textView1);     
Button getAnswerButton = (Button) findButtonById(R.id.button1);

Both should be findViewById if I remember correctly.

Yes, remember that a 'button' is still a UI view component.

Yeah it at first glance seems counter intuitive from having done a bit of HTML but then I guess a UI view is anything you want to display

Okay working on the Learning the Language Code Challenge, I got the first three right and I can't figure out what I'm doing wrong

Random randomGenerator= new Random();
int randomNumber = randomGenerator.nextInt(10);
answer = Integer.toString(randomNumber);

You haven't declared the type for answer. It should be: String intAsString = Integer.toString(randomNumber);
