Page crash when load Adbanner

[banhthanhvi]

xmlns:admod="clr-namespace:Plugin.MauiMTAdmob.Controls;assembly=Plugin.MauiMtAdmob" <admod:MTAdView Grid.Row="2" x:Name="myAds" AdSize="AnchoredAdaptive" IsVisible="true" AdsId="{Binding AdbannerId}" VerticalOptions="End" HeightRequest="{OnIdiom Phone=50, Tablet=90, Desktop=90}" />

My MAUI page has crash when add above code. I use:

• MauiMTAdmob 1.0.2
• .NET 7.0
• VS 2022 17.4.3
• Xcode 14.1 It ran ok with:
• MauiMTAdmob 1.0.1
• .NET 6.0

Do I miss something? Thank you.

It crashes on build iOS release.

I think this is a Xamarin.Google.iOS.MobileAds issue - if you call MobileAds.SharedInstance.Start in AppDelegate, it crashes because MobileAds.SharedInstance is null. Since this plugin relies on the Xamarin library, my guess is it's quietly doing the same thing.

You can test it by making this your AppDelegate. If you comment out the first line in FinishedLaunching it won't crash. You can also refer to this bug in the Xamarin GitHub: https://github.com/xamarin/GoogleApisForiOSComponents/issues/592

[Register("AppDelegate")]
public class AppDelegate : MauiUIApplicationDelegate
{
    protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();

    public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
    {
        MobileAds.SharedInstance.Start(AdsCompletionHandler);

        return base.FinishedLaunching(application, launchOptions);
    }

    private void AdsCompletionHandler(InitializationStatus status) { }
}

I tried the sample and it worked. Then I compared it with my solution and the problem was not with the library or the code, but with my target version of iOS, which was set too low on 11, I tested it on the same as in the sample 14.2 and it works! thank you :)

<SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">14.2</SupportedOSPlatformVersion>

I tested different versions and iOS 12 is not supported, so iPhone 5S and 6 are unlucky. every newer iphone should be ok.

Does not work on iOS 16.4.1...

"Object reference not set to an instance of an object" when adding a banner either by C# code or XAML

From version 1.0.3 this problem should have been solved.
