body: <p>I am a beginner in Xamarin and trying to use TabbedPage for my application. When I used TabbedPage and set the icons, it works fine.</p>

  <p>Then I set the TabbedPage position to bottom using below link</p>
  
  <p><a href="https://docs.microsoft.com/en-us/xamarin/xamarin-forms/platform/android/tabbedpage-toolbar-placement-color" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/xamarin/xamarin-forms/platform/android/tabbedpage-toolbar-placement-color</a></p>
  
  <p>However, when I run the application, the TabbedPage icons are not visible and even the width is too long for one Tab</p>

  <p>Below is my XAML code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;TabbedPage xmlns="//xamarin.com/schemas/2014/forms"
          xmlns:x="//schemas.microsoft.com/winfx/2009/xaml"
          xmlns:views="clr-namespace:App5.Views"
          x:Class="App5.Views.MainPage"
          BarBackgroundColor="LightYellow"
          BarTextColor="Black"
          xmlns:android="clr-namespace:Xamarin.Forms.PlatformConfiguration.AndroidSpecific;assembly=Xamarin.Forms.Core"
          android:TabbedPage.ToolbarPlacement="Bottom"
          android:TabbedPage.BarItemColor="Black"
          android:TabbedPage.BarSelectedItemColor="Red"&gt;
  &lt;TabbedPage.Children&gt;
      &lt;NavigationPage Title="Tab1" Icon="Tab1.png"&gt;
          &lt;x:Arguments&gt;
              &lt;views:ItemsPage /&gt;
          &lt;/x:Arguments&gt;
      &lt;/NavigationPage&gt;
      &lt;NavigationPage Title="Tab2" Icon="Tab2.png"&gt;
          &lt;x:Arguments&gt;
              &lt;views:AboutPage /&gt;
          &lt;/x:Arguments&gt;
      &lt;/NavigationPage&gt;
      &lt;NavigationPage Title="Tab3" Icon="Tab3.png"&gt;
          &lt;x:Arguments&gt;
              &lt;views:AboutPage /&gt;
          &lt;/x:Arguments&gt;
      &lt;/NavigationPage&gt;
      &lt;NavigationPage Title="Tab4" Icon="Tab4.png"&gt;
      &lt;x:Arguments&gt;
          &lt;views:AboutPage /&gt;
      &lt;/x:Arguments&gt;
  &lt;/NavigationPage&gt;
  &lt;/TabbedPage.Children&gt;
