@wangjingyang which version of the SDK are you using? is it crashing the app or just logging on to Logcat?

[wangjingyang]

v3.2.2 Yes, it crashed and was reported to firebase。 I think the code should be like this：

 private fun cleanSessionState(
        view: View,
        status: ViewTreeSnapshotStatus,
    ) {
        view.viewTreeObserver?.let { viewTreeObserver ->
            mainHandler.handler.post {
                if (viewTreeObserver.isAlive) { // Move this line of code inside the post code block
                    viewTreeObserver.removeOnDrawListener(status.listener)
                }
            }
        }
        view.phoneWindow?.let { window ->
            window.touchEventInterceptors -= onTouchEventListener
        }

        decorViews.remove(view)
    }

@wangjingyang I have a draft PR already https://github.com/PostHog/posthog-android/pull/134/files Thanks for reporting it, sorry about that. Not sure if it crashed tho, Since cleanSessionState is called by uninstall and the uninstall already swallows exceptions. Same for onRootViewsChangedListener. Maybe it'd crash because when we do mainHandler.handler.post, it's in a different scope so I have added another try catch anyway.

When will the new version be updated?

[marandaneto]

Once https://github.com/PostHog/posthog-android/actions/runs/9219736666 finishes running it'll be published, usually maven central has a few minutes delay as well
