Glance lets you write widgets in Compose-like Kotlin, but it emits RemoteViews rather than drawing. Knowing that explains the missing modifiers, the absent animations, and why state works the way it does.
A notification is rendered by the system UI, not your app, so Compose plays no part in its appearance. What a Compose app owns is the permission flow, the deep link, and the back stack the user lands in.
Predictive back shows a preview of the destination during the gesture. Supporting it means responding to progress rather than to a completed press, and the old BackHandler cannot express that.
Compose exposes system insets as composable values with padding, size and consume modifiers. Knowing the three safe-inset groups and how the keyboard inset animates resolves most edge-to-edge layout problems.
Targeting Android 15 makes edge-to-edge mandatory — the opt-out is gone. What that changes, what breaks, and why the fix is mostly about who consumes the insets.
