16. The problem seems to be the call “Integer.parseInt (s.toString ()) "when the string is an empty string (as shown above). Therefore, we change the code to check for this occurrence:


Now you know how to debug your application when connecting a real cloud mobile device from Perfecto Lab to your IDE. Check out the following feature when you create or run your own tests on different devices to make sure your apps work great on other platforms.
