App Crashing after clicking "PLAY AGAIN" Button

After coming to the last page of the story, when we click on the "PLAY AGAIN" button, the app crashes. When I take a look at the log, I see this error -

E/AndroidRuntime: java.lang.NullPointerException: Attempt to invoke virtual method 'int ~companyname~.interactivestory.model.Choice.getNextPage()' on a null object reference

Oh, this has happened to me so many times, you need every single line of code inside the OnCreate() method. Post your code if you are still having trouble.
