Argument type of Context.RegisterReceiver() is different from native API

[aqua-ix]

Android application type

Classic Xamarin.Android (MonoAndroid12.0, etc.)

Affected platform version

MonoAndroid 13.0, Xamarin.Android 13.1.0.1 , VS Mac 17.4

Description

I am currently updating the version of the target SDK for my Xamarin.Android project to version 33.

One of the new features of Android 13 is "Safer exporting of context-registered receivers".
https://developer.android.com/about/versions/13/features#runtime-receivers

To make my app compatible with this, I was going to change the RegisterReceiver call point as follows:

- Context.RegisterReceiver(receiver, filter);
+ Context.RegisterReceiver(receiver, filter, ReceiverFlags.Exported);

This implementation conforms to the specification of the following method: https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter,%20java.lang.String,%20android.os.Handler)

However, the above code failed to compile.
After investigating the cause, I found that the third argument of MonoAndroid's RegisterReceiver() overload is not of type Int, but ActivityFlags. This differs from the native API specification.

Please let me know why this is happening and if MonoAndroid plans to fix it.

Steps to Reproduce

1. Create new Xamarin.Android project that targeting MonoAndroid 13.0
2. Call the following overloads of RegisterReceiver at any position:
   RegisterReceiver(BroadcastReceiver, IntentFilter, Int)

Did you find any workaround?

I have confirmed that ReceiverFlags can be used with ContextCompat API and will consider replacing it with ContextCompat in the near future if this issue is not resolved.

It looks like this method has been enumified incorrectly as ActivityFlags instead of ReceiverFlags.

All enums in C# are really int behind the scenes, so you can cast them as needed to workaround this.

Context.RegisterReceiver(receiver, filter, (ActivityFlags)ReceiverFlags.Exported);

Thank you for your response.
I consider using type casting until this issue is resolved.
