Bug Information

Version Number of Plugin: 2.1.0.4 Device Tested On: Google Pixel 4 with Android 10.0 Simulator Tested On: none Version of Rider: 2021.2 Version of Xamarin.Android: 11.3.0.4 Versions of other things you are using:

Steps to reproduce the Behavior

In our application we have two activities, DialogActivity is opened on top of MainActivity. We use Settings -> Developer Options -> Don't Keep Activities turned ON to simulate system high load. While top activity (DialogActivity) is opened - minimize the app and then open it again.

Expected Behavior

CrossCurrentActivity.Current.CurrentActivity should return instance of DialogActivity

Actual Behavior

CrossCurrentActivity.Current.CurrentActivity returns instance of MainActivity

Do you see this behaviour with Xamarin.Essentials? This project is no longer maintained as James moved this behaviour into Essentials, You're better off removing this package and trying with XE 😄

Actually, we already did switch to XE) But it seems like XE has exactly the same implementation, at least in regards of updating current activity in OnActivityPaused(). I guess I need to double check the behaviour of XE and create an issue there, if needed.

Thank you!
