My first candidate for removal would be fragments. They don't help to componentize apps at all (at least not better than plain old viewgroups), but they can make life much harder with weird hidden bugs. There is brilliant article from Squareup about that - https://corner.squareup.com/2014/10/advocating-against-android-fragments.html https://corner.squareup.com/2014/10/advocating-against-andro... In Anvil I try to follow Square's approach, e.g. keep components as viewgroups and use a custom backstack to manage them as needed (e.g. back/home navigation, multi-pane layouts etc). Then you get just one activity per application and it's a big relief.
