I\'m using Android Studio 3.2 Canary 14 and The Navigation Architecture Component. With this you can define transition animations pretty much as you would when using Intents
As said, R.anim has the default animations defined:
nav_default_enter_anim
nav_default_exit_anim
nav_default_pop_enter_anim
nav_default_pop_exit_anim
But you can easily override them.
Just create your own four anim resources with the same names in your app module (just to clarify, the id of one of them is your.package.name.R.anim.nav_default_enter_anim) and write what animation you'd like.
