Enabling it in debug builds doesn't work. I always get the serial GC.
It works fine in Release builds.
I believe that this was fixed by: https://github.com/xamarin/monodroid/pull/581
Hi Rodrigo ,
It would be great if you can provide me steps or screencast link to validate this bug. I am also unable to access the link : https://github.com/xamarin/monodroid/pull/581 as well.
Can you help Neeraj here?
Long story short, enabling "use the concurrent garbage collector" property in android project options -> Android build should translate to the app having MONO_GC_PARAMS=major=marksweep-conc set at runtime. You can check this at runtime by adding to a sample android project : System.Environment.GetEnvironmentVariable("MONO_GC_PARAMS").Contains("major=marksweep-conc"); (it is true if it's passed and false or NullReferenceException if not passed).
As it was mentioned above this was reproducible only with debug builds. I think the latest Xamarin.Android build (from alpha) should have the fix and any build older than one week should be buggy.
