Android application crashing when bitmap is changed multiple times. #9510
Description
Android framework version
net8.0-android
Affected platform version
VS2022 ver 17.11.5 .Net 8
Description
On Android application we have two views A and B. both have bitmaps. We interchange these bitmaps between view A and B multiple times. Application get crash with error:
**[libc] Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x37 in tid 14029 (.NET TP Worker), pid 11449 ()**

Steps to Reproduce
- Create new project on Android with 2 views and add bitmap to it.
- interchange bitmaps multiple times between thses 2 views.
- It will crash the application. We are using worker thread pool to get the bitmaps from server and changed them using UI thread.
Did you find any workaround?
I could not find any work around so far.
