Sorry, it should have been about the number of methods limit in Android that is around 65,000 methods : https://developer.android.com/studio/build/multidex . I guess facebook worked around the limit but couldn't find a reliable source for it. There was also a post on Facebook iOS app with large number of classes but not essentially hitting a limit on the iOS platform : https://quellish.tumblr.com/post/126712999812/how-on-earth-the-facebook-ios-application-is-so . I guess it's the number referred but I could be mistaken. > > > > > > > > > If we're to adopt limits where there were previously none, we > > need to do > > > it via a multi-release deprecation cycle feedback loop to give > > people a > > > way to find report use cases that exceed the limits in real world > > > practical applications.
