Running into a similar issue, any update on this?

This is a platform behavior change.

b/236862874 is related.

Any progress?

Thanks for the comment#1 report. The bug in how those older versions of the framework dispatch insets does make handling insets difficult. It's on our roadmap for early 2025 to prepare an AndroidX-side workaround.

This issue is also stopping us from being able to support edge-to-edge in Android 15. Given it's a enforced requirement for targeting Android 15, couldn't this be prioritised higher? Companies like us have hundreds of screens to fix so waiting until 2025 for a workaround is going to be tough work.

Maybe you can create a static method, com.your.company.ViewGroupCompat#installCompatInsetsDispatch, like this: https://android-review.googlesource.com/c/platform/frameworks/support/+/3310617/2/core/core/src/main/java/androidx/core/view/ViewGroupCompat.java ?

After creating the method, you need to call ViewGroupCompat.installCompatInsetsDispatch(getWindow().getDecorView()) in onCreate() of your activity to make the behavior compatible with API 30+.

When the new library with the API is released, you can replace com.your.company.ViewGroupCompat with androidx.core.view.ViewGroupCompat.

Wow quick response, thanks! I just tried applying that workaround to our root view and can confirm it fixes the issue. (Also FYI there's a typo in the PR; "comsumed")

I'm getting a crash when using new version of ktx-core 1.16.0-alpha01 with fixed ViewCompat and ViewGroupCompat on API < 30. This is related to FragmentContainerView:

Re comment#13:

I think the @NonNull annotation of androidx.fragment.app.FragmentContainerView.setOnApplyWindowInsetsListener has been removed since If694a3b70bf84f03c95d67d20e58485135ab7d86 which has been included since androidx.fragment 1.4.0-alpha09.

Do you mind upgrading your androidx.fragment version to 1.4.0-alpha09 or above? The latest version is 1.8.5.

This bug has been fixed by I111590881991b94e5cd5f2100bf88dd4468bc781 since core#1.16.0-alpha01. Let's mark it as fixed.

See: https://developer.android.com/jetpack/androidx/releases/core#1.16.0-alpha01

I'm sure I was using the latest androidx.fragment 1.8.5. It can be reproduced here, could you check it?

Ah, you are right. It still requires a non-null object since the required type is not OnApplyWindowInsetsListener? but OnApplyWindowInsetsListener.

    public override fun setOnApplyWindowInsetsListener(listener: OnApplyWindowInsetsListener) {
        applyWindowInsetsListener = listener
    }

Hi Jeremy,

Do you mind checking why androidx.fragment.app.FragmentContainerView.setOnApplyWindowInsetsListener requires a non-null parameter? The restriction was added in this CL.
