Learn xamarin.forms from scratch (iii) Android production splash screen

Xamarin.Forms is very slow to start, you must add a boot interface, the steps are as follows: 1. Name the image of the splash screen as: splash_screen.png, and copy it to the appropriate drawable folder under the Resources folder; 2. In the Under the Drawable folder, create a splashscreen.xml with the content:

<?xml version= "1.0" encoding= "Utf-8"?> <bitmap xmlns:android= "Http://schemas.android.com/apk/res/android" android:src= "@drawable/splash_screen" android:gravity= "Fill" android:layout_gravity= "center"/>

3. Under the Resources folder of the Android project, add the "Values" folder, create the Styles.xml, set itsThe content is created as follows:

<?xml version= "1.0" encoding= "Utf-8"?><resources>  <style name= "Theme.splash"    parent= " Android:Theme.Holo.Light ">    <item name=" Android:windowbackground "> @drawable/splashscreen</item >    <item name= "Android:windownotitle" >true</item>    <item name= "Android: Windowistranslucent ">false</item>    <item name=" android:windowisfloating ">false</item>    <item name= "android:backgrounddimenabled" >true</item>  </style></resources>

4. Create a SplashScreen.cs class under the Android project with the following content:

[Activity (Mainlauncher = true, Nohistory = true, Theme = "@style/theme.splash",    configurationchanges = configchanges . screensize | Configchanges.orientation)] public    class splashscreen:activity    {        protected override void OnCreate ( Bundle bundle)        {            base. OnCreate (bundle);            var intent = new Intent (this, typeof (Mainactivity));            StartActivity (intent);            Finish ();        }    }

5. Remove "Mainlauncher = true" from the MainActivity.cs class.
