How to set windowLightStatusBar in Xamarin.Forms (Android)?

I want to use a light background for the status bar and for better visibility I need to have dark status bar icons. Setting the background color works fine, but switching to dark icons with setting windowLightStatusBar to true does not work.

If I try the same with a Xamarin.Android app this works without a problem. TargetFramework ist Android 7.1 (API Level 25) for each.

This is how my MainTheme in style.xml looks like:

  <style name="MainTheme" parent="Theme.AppCompat.Light">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">#0000ff</item>
    <item name="colorPrimaryDark">#dddddd</item>
    <item name="android:statusBarColor">#ff0000</item>
    <item name="android:windowLightStatusBar">true</item>

    <item name="android:colorAccent">#FF4081</item>
    <item name="android:windowActionModeOverlay">true</item>

But it results in this:

Obviously items with android: are ignored. But I can't compile statusBarColor and windowLightStatusBar without it.

And this is how it should look like (attempt in Xamarin.Android):

Can anybody tell me how to achieve this or what I'm doing wrong, please?

    I posted a sample here on how you can change the status bar color

    @NMackay: Thank you for your answer, but my problem is setting the status bar icons to dark gray (like second screenshot with Xamarin.Android app). I know changing the status bar color works fine by setting colorPrimaryDark.

    I the meantime I've found out that the items with android: are not ignored. They just seem to be overwritten in the process of loading:

    After setting a breakpoint in MainActivity.OnCreate, I recognized that the status bar did become red (#ff0000, like defined with android:statusBarColor) and the icons are dark. But after continue the status bar will be set to light gray (#dddddd; like defined with colorPrimaryDark) and the icons become white again.

    Any ideas what is causing this "overwriting"?

    Looking a bit further into this apparently it's supposed to be white according to the Android styling guidelines

    "Notification icons must be entirely white. Also, the system may scale down and/or darken the icons."

    There's a few workarounds suggested here but they are very API level dependant if they work....

    But "Notification icons must be entirely white..." refers to new icons provided by the app. What I want is, that "the system may scale down and/or darken the (existing) icons."

    This guideline was introduced with Android L (5.0, API 21). But with Android M (6.0, API 23) they introduced windowLightStatusBar (unable to post a link) which should darken the icons.

    As mentioned this actually works in a Xamarin.Android app like expected, but I can't get it to work properly in a Xamarin.Forms app.
