Description

Android app crashes while using setAccessibilityFocus.

const reactTag = findNodeHandle(ref); AccessibilityInfo.setAccessibilityFocus(reactTag);

I’ve fixed it by adding <View accessible={true} />. I think react-native should provide some description for common sources of such errors. “Could not find view with tag” useless for me. This is not user friendly.

It would at least be good to be able to catch the error. The following does not work, and will crash the app:

try {
    const reactTag = findNodeHandle(ref)
    AccessibilityInfo.setAccessibilityFocus(reactTag)
} catch (e) {
    // do nothing
}
