title: java.lang.NumberFormatException: Invalid int: "" in android
body: <p>I already know what is causing this error, I just do not know how to handle the case when a user doesn't enter anything into the dialogue box, then hit the button which parses the string into an int. It can't parse an empty string into an int, so it throws an error. I have done some research on how to do this, but have not found a satisfactory result that works.</p>
  
  <p>Problem: How do you check to see if the dialogue box has text in it, before it tries to run the rest of the code. </p>
