Google UMP for Xamarin (Android and iOS)

A cross-platform wrapper for Google's User Messaging Platform for Android and iOS.

https://developers.google.com/admob/ump/android/quick-start https://developers.google.com/admob/ump/ios/quick-start

Installation

Available (as a preview) on Nuget Plugin.GoogleUserMessagingPlatform

You must add the package to your iOS and Android head projects, as well as any shared projects you want to access the library from.

Implementation

Android

Uses the Android UMP binding from Xamarin Components:

https://github.com/xamarin/XamarinComponents/ https://www.nuget.org/packages/Xamarin.Google.UserMessagingPlatform/1.0.0

iOS

Uses the iOS UMP binding that is currently part of Xamarin.Google.iOS.MobileAds:

https://github.com/xamarin/GoogleApisForiOSComponents https://www.nuget.org/packages/Xamarin.Google.iOS.MobileAds/7.66.0

Usage

On Android, make sure Xamarin.Essentials.Init is initialized, either in Activity.OnCreate or Application.OnCreate. For example:

public class MainApplication : Application
{
    public MainApplication(IntPtr handle, JniHandleOwnership transer)
        : base(handle, transer)
    {
    }

    public override void OnCreate()
    {
        base.OnCreate();
        Xamarin.Essentials.Platform.Init(this);
    }
}

Then use something like the following somewhere in the start-up flow in your cross-platform code:

var ump = UserMessagingPlatform.Instance;
if (ump.IsSupported)
{
    var parameters = new RequestParameters
    {
        DebugSettings = new ConsentDebugSettings
        {
            // Optional, for testing
            Geography = DebugGeography.Eea
        }
    };
    var consent = await ump.GetConsentInformationAsync(parameters);
    if (consent.ConsentStatus == ConsentStatus.Required && consent.FormStatus == FormStatus.Available)
    {
        await ump.LoadConsentFormAsync();
        await ump.ShowFormAsync();
    }
}

More reading

See the original documentation from Google for more information:

https://developers.google.com/admob/ump/android/quick-start https://developers.google.com/admob/ump/ios/quick-start

Apart from minor renames, the API matches the original.

The only exception is the addition of the IsSupported property. This returns true on Android and iOS and false on .NET Standard. All other methods throw PlatformNotSupportedException when called from .NET Standard.
