Activity 1.12.0-beta01 is out with a behavior change on how system back is handled - the Lifecycle aware OnBackPressed APIs now enable/disable callbacks rather than register/unregister them, ensuring a more consistent ordering.

Let us know if you are impacted!

WorkManager 2.11.0 raises the minSdk from 21 to 23. That change meant that the team could remove 3,739 lines of code and the AlarmManager based scheduler used to support older versions of Android. Welcome to a leaner WorkManager!

Are you talking about the import statements themselves? Because no one looks at those - in fact, many developers use 'star imports' which collapse them down to just one line for an entire package

If instead you mean, it is unclear what to import when looking at the list of suggestions, that's valid

There's a lot more building blocks in Compose vs canned pre-built components (although quite a few of the Material3 components are close to that).

Was there particular things you felt like had a lot of boiler plate?

Take a look at how we do metadata in NavDisplay, etc. - that title { } example is exactly the kind of type safe API you write for your specific use case.

Ian Lake @ianlake.bsky.social · 11d

But I think your example is putting information at the wrong level - titles shouldn't be a property on keys in your back stack at all. Scenes don't even have access to the key classes!

Instead, you should be looking at NavEntry metadata, which lets you write metadata = title { stringResource(..) }

Ian Lake @ianlake.bsky.social · 11d

The generics on your Scene need to match the generics on your NavDisplay, which I assume would be AppNav (although I'm not sure why you'd want an empty interface when NavKey already exists), so doing Scene<SubsettingNav> doesn't make much sense.

Navigation3 1.0.0-alpha11 makes a significant number of API changes: onBack no longer takes a count, Scene's have their own metadata to allow their own defaults/overrides of the NavEntry metadata, plus changes to the Scene and Decorator APIs.

That, along with synthetic back stacks and different handling whether you are on your own task stack or another apps' task stack (which is the only time when back and up differ), is going to be the next PR after this first one.

There are no Hilt specific APIs on that page.

Ian Lake @ianlake.bsky.social · 19d

You'll have to be more specific on what your setup is. Navigation2? With Fragments? With Compose?
