[Flutter 3.22] ARFoundation crashes on Android < 13 - NoClassDefFoundError: Landroid/window/OnBackInvokedCallback #21

Open timbotimbo opened 2 weeks ago

Description

Since Flutter 3.22, Unity will crash on certain Android versions when ARFoundation is activated.
This only happens on Android <13. This might also affect other unity plugins using native code, I just noticed it using ARFoundation.

In my own project Unity works fine for 3D scenes but crashes when I switch to a scene that includes ARFoundation. In the example project here, Unity shows up with the Flutter logo but crashes once the AR support check runs.

Error in the console:

Looking up OnBackInvokedCallback, it is added in API 33 (android 13) and is related to the predictive back gesture in Android 14.

I'm not sure if this is a flutter bug where it sends some kind of message which it shouldn't on API <33, or if it is caused by Unity missing an implementation.

Some things I've tried

timbotimbo commented 2 weeks ago

Narrowed it down to this commit on Flutter master. Which includes the engine PR Platform channel for predictive back in route transitions on android

timbotimbo commented 6 days ago

With some custom plugin modifications I managed to try this on Unity 2023.2.20 and 6000.0.7. 6000.0.7 even has a Predictive Back Support toggle in the player settings.

I'm still getting the same error, so I will probably have to open an issue in the Flutter repo.
