Somebody that wants to jump right in and use the RecyclerAdapter, might just skip through the ListAdapter example and forget to call cleanup() on it.

Also, the method name seemed to be incorrect in the instructions but right in the code: instead of release() the correct method is cleanup() just like above.

Thanks for the PR and good catches. I'm not sure how that release() snuck in there, because the method has always been called cleanup(). Well.... fixed now. Thanks again!
