What’s the recommend practice loading user-data during app startup and routing to the appropriate navigation route using Jetpack Compose and the Splash Screen API. The easiest solution would be to have a separate “splash” activity, that checks if the user is logged in and routes to the “Main” activity, otherwise routes to a “Login” activity. To me, it seems odd/wrong to have multiple activities when all UIs are fully built in Compose and the activities only exist so that I can perform loading/routing during startup.

Generally you do this all in one Activity, separate nav destinations for Login and Main. Are you working on an existing app that has multiple activities?

It would be a completely new app.

Then you only need one Activity.

If a user is able to use your app in some capacity without logging in, then that screen / destination will be your root destination. On that screen presumably there’s a way for them to reach the login destination if they want to.

If a user must log in to make any use of your app, you can take the approach of having a splash/loading destination, which just shows a loading spinner for example, while your app checks if the user is logged in or not. If they’re logged in, go to your Main destination. Otherwise go to Login destination

Ian lake has stated a bunch of times that navigation component's rec on how to do this isn't specific to navigation-compose. so you can use his video from a few years ago here with a case study on login
