Are there any plans to replace unsupported APIs (KEYCODE_BACK and #onBackPressed) to support Android's new Predictive back gesture?

[dzuluaga]

Description

Apps using React Native targeting enableOnBackInvokedCallback might break if they use the code that references the unsupported APIs like KEYCODE_BACK and #onBackPressed). Therefore, we recommend migrating to OnBackPressedCallback to support the new back gesture experience and avoid any breakages.

Are there any plans to replace these APIs?

Context

Android 13 introduced the Predictive Back gesture, which enables users to visualize where they're going to land before completing a back swipe.

Version

0.68

Output of npx react-native info

N/A

Steps to reproduce

1. EnableOnBackInvokedCallback=true in the AndroidManifest.xml of any given app
2. Target AndroidSdk 33
3. Use the back gesture in an app that uses unsupported APIS:
   • OnBackPressed ReactActivity, ReactDelegate, ReactFragment, ReactActivityDelegate, ReactAppTestActivity, ReactInstanceManager
   • KEYCODE_BACK ReactModalHostView

Hi @dzuluaga, thanks for brining this to our attention. The predictive back gesture is a developer only feature in Android 13, so we have some future plans to migrate to the new APIs before they are enforced in the next Android release in 2023.

We've already started looking into the existing callsites, and currently investigating the migration paths.

@makovkastar Nice, thanks for the info. Any plans on working with authors of navigation libraries like me (Navigation router) or software mansion (react native screens cc @kkafar)? I think we both use the Fragment back stack so the predictive back gesture should work for us out of the box - as long as we can turn off React Native back handling.

Android 14 will be released soon. Is there an update on this?
