Hello, I want to report bug and find workeround.

When I start app on android in debug, then app disconected forom debuger or crash, immediately after I add layer to BaseLayers. Sometimes it survives adding and crash after map movment. Is there any solution?
Example in attachment.

Ps.

If you start app withou debuging it works fine. The problem is happening to me on two different apps on different computers with Visual studio.

Does this issue only occur on Android? If you run on Windows or iOS do you see any errors otherwise? What Android device are you using, and have you tried different devices?

Hi,
Yes issue apearing ony on android, I have multiple devices. Samsung S22 Android 14, Emulator API 33, Emulator API 34, Android Stonex with RTK antena android - 10. In all of this devices I have the same problem.
Unfortunately I have no logs there and there is no exception. It just crash after adding map layers to the map. I think it is after OnPropertyChangeEvent but I'm just guessing, and it is happening only on debug.

I have last VS 17.8.6 and also VS-pre - 17.9.0.
Esri - Maui 200.3.0

Net.8

I tried your sample and had no problem running and debugging it on an Android device, and I see the open street map. I'm still on 17.8.3, but it sounds like something in your debugging experience is broken.

Thank you for trying and looking for a solution. I also tryed it on another computer with VS 17.8.4, also on JB - Rider, main problem is that this crash is mostly happend on second run. Than if you move with map it crash.
I don't want to bother with it. I'll try to figure it out myself. But the issu is there and it won't be just me. Maybe someone else will have a problem with it in the future. So we'll see. Thank you for your time. If I manage to find out anything else, I'll let you know.

I've managed to reproduce this using your reproducer in VS 17.8.5 on a Pixel 6 (Android 14) and an emulated Pixel 5 (Android 11).

I'm going to try to reproduce it in a separate solution then investigate further.

Thank you for letting us know, we'll continue looking into this.

What .NET Version and Maui SDK do you have? (enter "dotnet --version" and "dotnet workload list" in commandline).

I still got 8.0.100 (Android workload 34.0.43/8.0.100), but there's an 8.0.101 now. I'd be curious if Microsoft maybe broke something in that version.

Please uninstall preview versions, and use the supported versions. Previews versions will often have goblins

I can do it, but i had a supported version before. The preview version I installed only before I hoped that will solve the issue.
