fireStateAtPath crashes on Android

[dan-phantom]

Description

The app (expo client) crashes when trying to use fireStateAtPath

Provide a Repro

The issue seems to be that it doesn't find the StateMachine in the native side.
Sadly I cannot provide a riv file but it works on both iOS and web - with fireStateAtPath - so the riv file is fine.

fireState also works fine

        const fireStateOrfireStateAtPath = (stateName: string) => {
          if (stateName.includes("/")) {
            const [state, ...path] = stateName.split("/").reverse();
            riveRef.current?.fireStateAtPath(state, path.reverse().join("/"));
          } else {
            riveRef.current?.fireState(stateMachineName, stateName);
          }
        };

Any ideas? Thank you ❤️

[leemhenson]

I have encountered exactly this issue, also via fireStateAtPath to trigger an animation in an artboard. I believe the bug has been resolved in rive-android 9.9.2 here and documented in the release notes here.

Currently rive-react-native is locked to rive-android 9.5.1 here.

How much of a jump is it from 9.5.1 to 9.9.2? Could you provide any idea how long it's likely to take to pull this bug fix in? Or would it be possible to backport the fix in rive-android to a new 9.5.1-patch or equivalent?

Thanks

@leemhenson probably a patch-package will do it
