Lottie Animation没有出现在Android设备上-Xamarin Forms

我正在使用VS 2019 xamarin Forms，最近我观看了一些有关如何使用抽奖动画的视频，而且看起来非常简单.我正在做每一个步骤，但是当我运行该应用程序时，动画永远不会出现.

I'm using VS 2019 xamarin Forms, I recently watched some videos about how to use lottie animations and looks pretty simple. I'm doing every step but when I run the app the animation never appears.

Package Com.Airbnb.Lottie.Forms已添加到所有应用程序项目中(它是跨平台的)然后将Com.Airbnb.Android.Lottie添加到Android应用程序中(首先，我尝试不使用它，也无法正常工作)

Package Com.Airbnb.Lottie.Forms was added to all app projects (it's crossplatform) Then added Com.Airbnb.Android.Lottie to the Android app (first I tried without it, didn't work either)

这是代码

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
             xmlns:lottie="clr-namespace:Lottie.Forms;assembly=Lottie.Forms"
             x:Class="AppWasher.MainPage">

    <StackLayout>
  
        <lottie:AnimationView
            x:Name="animationView"
            Animation="26617-ogad.json"
            RepeatMode="Restart"
            VerticalOptions="FillAndExpand"
            HorizontalOptions="FillAndExpand"
            WidthRequest="300"
            HeightRequest="300"/>
        
    </StackLayout>

</ContentPage>

这是乐透提供的指南

<forms:AnimationView
    x:Name="animationView"
    Animation="LottieLogo1.json"
    AnimationSource="AssetOrBundle"
    Command="{Binding ClickCommand}"
    RepeatCount="3"
    RepeatMode="Restart"
    VerticalOptions="FillAndExpand"
    HorizontalOptions="FillAndExpand" />

我也尝试使用所有这些属性，结果相同.

I tried using all those properties too, same result.

我正在Android 9.0版上进行测试

I'm testing on Android 9.0 version

还将json文件添加到android项目中的assets文件夹中，并将构建操作设置为AndroidAsset

Also json files were added to the assets folder in the android project and build action is set to AndroidAsset
