Hello, I see that an AndroidExternalSurface inside a screen in a NavHost is not affected by `NavHost`'s enterTransition and exitTransition (due to the Surface having its own window I guess), how do I make it animated like the rest of the screen anyway?

It comes with a ton of limitations. Try with an AndroidEmbeddedExternalSurface

(it's SurfaceView vs TextureView)

Thanks @romainguy, much better behavior!

Note that AndroidExternalSurface is better for battery though

[romainguy]

So if you are displaying long content, consider using that

@romainguy If you need to use AndroidExternalSurface because of battery life concerns is there any work around to use in order to get the surface to animate correctly?

[romainguy]

A transition with only translate/scale/fade could work but I don’t know enough about the internals of the transition system to fully answer this

[romainguy]

The problem is that a surface view is a second window. Work was done in recent (>24) api levels to properly sync both windows but that assumes you don’t need to relayée, crossfade, etc.
