I am getting the same thing. My code is [CODE] public void onClick(View v) { //The button was clickes, so update the fact label with a new fact. String fact = ""; //Randomly select a fact Random randomGenerator = new Random(); //construct a new Random number generator int randomNumber = randomGenerator.nextInt(3); fact = randomGenerator + ""; //Update the label with our dynamic text factLabel.setText(fact); } [/CODE]

Never mind. I just figured it out. I was accidentally calling randomGenerator instead of randomNumber at the end.

Make sure you wrote down that fact = randomNumber and not randomGenerator
