Esri.ArcGISRuntime.Maui version 300.0.0 hangs when used in .NET MAUI Android app

[mfeingol]

I recently began using MapView inside my .NET MAUI Android app on .NET 10. The functionality I use is fairly straightforward:

1. A base map using a custom ImageTiledLayer implementation

2. Icons and polylines using various symbols and graphics

In the hang scenario, my phone is offline and the screen is turned off. I am recording my location inside my app, and rendering it to the MapView as a polyline when the phone is turned back on. What I see is the following:

1. After some time with my phone off, I turn it back on and sign in

2. The MapView is 100% unresponsive. It won't scroll or respond to taps.

3. The app itself remains perfectly responsive. I can go back and re-enter the page. I can switch the map to use Google Maps and then back to a new instance of the ESRI MapView. New instances work fine.

The issue is difficult to reproduce with more casual usage, so I don't have an easy repro or a thread dump from a debugger.

Any ideas?

Could you provide some more info

- Android OS version

- Android device 

Did you try on multiple devices? The problem could be specific to a device, we have seen similar issues in the past and found problem is often times specific to a device/model.

This is on Android 16 on a Samsung S24+. I haven't tried this on other devices yet. But this is a fairly mainstream device, and I'd be very surprised if it was specific to the device/model. It seems much more likely you have a lifecycle issue when an app is suspended and resumed. Could you please look into that?
