How to implement Android splash screen using svg instead of png?

I make RN app. For Android version I have made /drawable/splash_screen.xml with following content

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

  <item
    android:drawable="@color/gray"/>

  <item>
    <bitmap
      android:gravity="center"
      android:src="@mipmap/ic_launcher"/>
  </item>

</layer-list>

and links to this file in res/values/styles.xml

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/splash_screen</item>
</style>

also in AndoirdManifest.xml

<application
  android:name=".MainApplication"
  android:allowBackup="true"
  android:label="@string/app_name"
  android:icon="@mipmap/ic_launcher"
  android:theme="@style/AppTheme">
  <activity
    android:name=".MainActivity"
    android:label="@string/app_name"
    android:theme="@style/SplashTheme"
    android:screenOrientation="landscape"
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>
  <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>

This works fine, but I'd like to make SVG file instead PNG (mipmap/ic_launcher). The SVG file might be like this https://developer.android.com/reference/android/graphics/drawable/AnimatedVectorDrawable.html (at least without animation). How to achieve this?
