title: Passing a simple variable value for use in another class in Android
body: <p>What is the correct way to pass a simple variable which has its value set to use in another class? I have a counter which is incremented with a button press and when counter = 3 a method is called which loads another activity which loads another screen with a string which states the button was pressed. Here is where I want to include the number 3 passed from the counter variable in the previous class, but I am not sure the correct way to do this. 
  I tried creating an instance of the class and connecting to the variable that way but the value is never passed and it is always 0.</p>
