Mark has a level of expertise in Android, including UI design, that is very hard to match. You will be better off if you take everything he writes, whether in his books or in his posts, very seriously, no matter how much it hurts.
Having worked in the mobile software industry since about 1998 myself, I have to agree 100% with Mark: you must be doing something wrong if you think you need hundreds of checkboxes in one activity. This would be irritating enough to the user on a desktop, but it will be much, MUCH more irritating on a phone or even a tablet. Find a way to reduce the number of checkboxes by means of a preceding question, even if it is something as crude as asking if the checked item is spelled with letters 'A' through 'F' etc. Your users will curse you if you force hundreds of checkboxes on them all at once.
