Listing 2.9


Concerning listing 2.9 on page 42 of Kindle ebook

I have to add …
TextView mQuestionTextView=(TextView)findViewById(;

to the update() class to keep the activity from exiting on an error when I press the NEXT button. As long as its within update() section of code everything is fine. The book doesnt say I should have to do this. What am I missing?
