Their ios app has over 18000 classes (https://www.reddit.com/r/programming/comments/3h52yk/someone_discovered_that_the_facebook_ios/ https://www.reddit.com/r/programming/comments/3h52yk/someone...), so I can easily believe the android app is similarly bloated as well. (To be fair, most of the 18K classes seem to be auto generated, but that still doesn't lessen the compiler's burden.)
