Main activity has a CoordinatorLayout in which there is an AppBar and a FrameLayout for fragments, a NavigationView and a FloatingActionButton.
We have more than 50 fragments. More than 40 fragments use the same simple toolbar/actionbar/appbar (truly annoying architecture, design, and naming by Google guys, and we still can't really differentiate them). They only need a back button, a simple title, and the icon for opening/closing navigation menu. The rest of the fragments have their own icons and might be taller.
We saw some questions, including this question:
Coordinator Layout with Toolbar in Fragments or Activity
Based on it, we decided to use a FrameLayout inside our main AppBarLayout and just like fragments, use FragmentManager to replace it for custom AppBarLayouts. Are we safe following this decision? We can't come to another solution for not repeating common toolbars across fragments.
