Connecting Bluetooth device causes crash (stemming from MediaBrowserService.OnDestroy())

[rhedgpeth]

🐛 Bug Report

Currently have an app that will crash when connecting a known bluetooth device. The app itself targets Android 12, and is using Plugin.MediaManager.Form v1.1.1. It also seems to be occurring almost exclusively on Google Pixel devices, if that's at all helpful.

It's unclear to me what is causing the crash, but I suspect, based on some of the logs below, that it might have something to do with the targeted Android version (possibly related to this feature request?) Or maybe it's environmental.. not sure.

This might be fixed in 1.2.2
