Java.Lang.IllegalStateException when resuming the App from an Android Autofill Service

[dinisvieira]

Description

When using an android app that has an Autofill Service if we create an intent for "Autofilling" a field that opens the app again the app crashes on base.OnCreate();
This only seems to happen when using a "non-shell" implementation.

The Activity used for that Intent doesn't seem to matter. On the reproduction sample two different activities can be chosen for opening the app from the Autofill Service but they both crash on base.OnCreate().

Steps to Reproduce

• Clone attached public repo
• Run app
• Press "Click Me" button
• On the Autofill service screen choose "Test Fill Service"
• Without closing the app open a browser
• Open a site with a text input field and tap on that input to get focus and an option overlay should appear
• Click the option "Click to Crash!"
• App will crash on Activity base.OnCreate()

Doing the same steps with MainPage = new AppShell() doesn't crash the app.

Version with bug

8.0.0-rc.2.9373

Is this a regression from previous behavior?

Yes, this used to work in Xamarin.Forms

Last version that worked well

Unknown/Other

Affected platforms

Android

Affected platform versions

Android 10 and up (at least)

Did you find any workaround?

Using new AppShell() doesn't crash but this is not an option for us. We are migrating an entire "non-shell" app from Xamarin Forms.

If this issue cannot be fixed immediately. Do we have any workaround for this issue? I am facing the similar problem which I have reported under #18159.

This is blocking our development migration from Xamarin to MAUI.
