This issue was previously reported: mono/mono#9314
But seems to be broken in latest Xamarin.Android versions.

We tried setting the following params but did not work
MONO_GC_PARAMS=bridge-implementation=new,nursery-size=128‌​m,soft-heap-limit=51‌​2m

We set the param like below in Application's onCreate() method.
Java.Lang.JavaSystem.SetProperty("MONO_GC_PARAMS", "bridge-implementation=new,nursery-size=128‌​m,soft-heap-limit=51‌​2m");

Steps to Reproduce

No exact steps to reproduce

Did you find any workaround?

No

@pubudulk This crash appears to be generated by Xamarin.Android classic, which is already out of support and will not receive fixes, alas. Can you update your app to net8 (you do not need to use MAUI) and see if the failure happens there as well? Thanks!

Note that this is a well known issue that still happens on .NET8. I haven't yet been able to reproduce it, the current workaround is to use new bridge instead. This issue should be closed. Tracked in dotnet/runtime#106410 (comment).

Are you suggesting to use the Environment.txt file approach rather than code approach mentioned below? We tried setting the bridge implementation like below but it didnt work.
Java.Lang.JavaSystem.SetProperty("MONO_GC_PARAMS", "bridge-implementation=new,nursery-size=128‌​m,soft-heap-limit=51‌​2m");

@pubudulk Environment.txt should be used, yes.
