[BUG] Net 9 Android - StatusBar Color overriden on modal pages

[Zack-G-I-T]

Is there an existing issue for this?

Did you read the "Reporting a bug" section on Contributing file?

Current Behavior

In MAUI Android, when adding StatusBarBehavior to change the color, and then going to a modal page - the status bar color gets replaced with the colorPrimary color from colors.xml.

This only happens on NET 9. In NET 8 the status bar color remained the same as the previous page.
I think its because int NET 9 in the App.cs you have to create a new Window for the app shell, but is there a solution to the status bar changing?

protected override Window CreateWindow(IActivationState? activationState) { var window = new Window(new AppShell()); return window; }

Expected Behavior

In the modal page, the status bar color should be the same as the previous normal page. This was the behaviour in NET 8

Steps To Reproduce

1. Open repo
2. Run in NET 9 for Android and click on the button - see the status bar color change from orange to green/red.
3. Change to NET 8 - see the color stays orange throughout.

The Xaml override breaks the build as well. I had to comment out the following in MainPage.xaml for it to work.

<mct:StatusBarBehavior StatusBarColor="{Binding AppColor}"></mct:StatusBarBehavior>

@brminnick Hi , you linked a generic pull request , are you saying that #2215 will fix the issue? do you have a nightly build release that we can test? thanks again for your free time you dedicate to this project

[pictos]

@gabsamples6 we aren't sure that will fix the this issue. But right now the MCT doesn't support .Net 9, it will when that PR gets merged, and if that doesn't fix this issue then we will investigate.

Probably the reason this is failing is because the change I made on how modal works in .Net Maiu, so we will need to update here, but any .net9 fix is blocked by the linked PR

@pictos thanks for your reply, loved your video on memory leaks! any idea when you will release .net 9 version as the .net maui team released the nuget SR2

[bijington]

I don't think they have release SR2 yet. I think it's due out tomorrow. Once it is out I expect us to work hard to get it done quickly

@bijington Hi, I think the Maui team did a release yesterday but seems very minimal stuff , I guess what you are after is not included. What do you think?

[bijington]

Sadly you are correct. They released SR1.4 but we need SR2

[gabsamples6]

@bijington actually they seem to have updated the release notes and there is way more stuff that original posted when they released the nuget. Does it have what you need to release the .net 9 version of the toolkit

[bijington]

@gabsamples6 they did another release (SR2.1) which does have the fix but it also has brought in another issue that we are now having to try and diagnose.

@brminnick @bijington @gabsamples6 I tested the linked repo using the latest package references and the issue still occurs. Should this actually be marked as completed?
