I experienced the same issue using Xamarin Forms v4.7.0.968 but discovered this line CrossCurrentActivity.Current.Activity = this;
within the protected override void OnCreate(Bundle savedInstanceState)
MainActivity.cs file for the Android project. This requires the namespace using Plugin.CurrentActivity; . This solved the issue for me and the null reference error no longer appeared when I attempted to force a specific page, in my shared project, to only utilize portrait mode protected override void OnAppearing() { base.OnAppearing(); try { if (Device.Idiom == TargetIdiom.Phone && CrossDeviceOrientation.IsSupported) CrossDeviceOrientation.Current.LockOrientation(Plugin.DeviceOrientation.Abstractions.DeviceOrientations.Portrait); } catch (Exception) { //TODO: log exception } }
P.s. ensure you have the nuget package installed for each project. Xamarin.Forms sample
I am using this plugin in my xamarin forms app. But when I want to change the orientation to Landscape app getting crash and giving me a NullReferenceException in Android.
Android version 9(Pie) Xamarin.Forms version is 4.2.0.848062
