Description

ManageSpaceActivity not working since update to .NET9

[assembly: Application(
#if DEBUG
    Debuggable = true
#endif
  , ManageSpaceActivity = typeof(ManageSpaceActivity)
    )
 ]
´´´

this causes the build to fail:

### Steps to Reproduce

- Add an activity to the solution
- Set ManageSpaceActivity on Application attribute
- Build

### Did you find any workaround?

No.
Wiring the fully qualified name in Android Manifest directly did not solve the issue. 
The activity was not available in the Android application menu

### Relevant log output

```shell

Activity

    If you want to use the fully qualified name in the AndroidManifest.xml you will need to use the "mangled" name unless you specify a Register attribute on your ManageSpaceActivity.

    If you look in your obj/Debug/netX.0-android/android/AndroidManifest.xml which is the final manifest, you can see the "managled" versions of the types. They will be something like android:name="crc64fdd50140bdf7fe6b.ManageSpaceActivity".

    The crc64fdd50140bdf7fe6b value is the encoded namespace of the type it will be a different value for your specific application. This is done to make sure we do not go over the Path limits on windows as java code has to be placed in subfolders and we quickly run out of path characters.

    If you use the Register attribute you can provide the string type you want to use eg.

    [Activity(Theme = "@style/Maui.SplashTheme")]
[Register ("com.foo.bar.ManageSpaceActivity")]
public class ManageSpaceActivity: Activity {
}

    As for the bug, it looks like we are defining the Type on the Attribute, but want to resolve that to a string for the xml file.

    Heh, I guess I touched this last. I'll look and see if I broke something. 😆

    Thanks :-)
    By the way:
    Using Register attribute and putting the name directly into the manifest fixed it for us.
    Thanks for that too :-)
