MAUI Window already created on specific devices

Question

I'm getting a weird issue on my dotnet MAUI app, it works great for me, the issue doesn't run for any other phone but one person's One Plus.

AppCenter screenshot

I can't figure it out and I don't see any other issues posted online for this

I don't know what to even attempt other than remaking the entire app

Answer 1

Same here with MAUI 8 preview. I can see the same error in the AppCenter with that OnePlus 8 device (Android 11), but I can't reproduce it.

Stacktrace:

Microsoft.Maui.Controls.Window.Microsoft.Maui.IWindow.Created()
Microsoft.Maui.LifecycleEvents.AppHostBuilderExtensions.<>c.<OnConfigureLifeCycle>b__2_0(Activity activity, Bundle bundle)
Microsoft.Maui.MauiAppCompatActivity.<>c__DisplayClass8_0.<OnPostCreate>b__0(OnPostCreate del)
Microsoft.Maui.LifecycleEvents.LifecycleEventServiceExtensions.InvokeLifecycleEvents[OnPostCreate](IServiceProvider services, Action`1 action)

Android.Runtime.JNINativeWrapper.Wrap_JniMarshal_PPL_V(_JniMarshal_PPL_V callback, IntPtr jnienv, IntPtr klazz, IntPtr p0)

Workaround

• Override the MainActivity.cs/OnPostCreate method
• Call base.OnPostCreate(savedInstanceState) in a try catch block.
