Connecting Bluetooth device causes crash (stemming from MediaBrowserService.OnDestroy()) #873

🐛 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.

08-17 12:09:47.397  5621  5621 V mono-stdout: Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.
