How can I generate random number in specific range in Android?

Here is my scenario
From the Mainactivity ; On click of a Button i want to generate a random number from 1 to 4
Based on the output, i want to write an if-else that will call 4 different activities

So on click, if 4 is generated, then call activity 4
Next time 1 can be generated and should call activity 1
and so on ….

Can someone please help me with this code?

myBtn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub

            Random r = new Random();
            int index = r.nextInt(4)+1;

            Intent intent;

            if (index == 4) {
                intent = new Intent(Activity.this, Activity4.class); 
            }
            else if (index == 3) {
                intent = new Intent(Activity.this, Activity3.class); 
            }
            else if (index == 2) {
            intent = new Intent(Activity.this, Activity2.class); 
            }
            else 
            intent = new Intent(Activity.this, Activity1.class);                    

            startActivity(intent);                
         }
