how to init animated vector in kotlin

I followed this tutorial and created my first animated vector in android studio.

my vector is:

<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:aapt="http://schemas.android.com/aapt"
  android:width="491.4dp"
  android:height="297.83dp"
  android:viewportWidth="491.4"
  android:viewportHeight="297.83"
  android:drawable="@drawable/ic_logo">
  <target android:name="name1">
    <aapt:attr name="android:animation">
      <objectAnimator
        android:duration="2000"
        android:repeatCount="-1"
        android:repeatMode="reverse">
        <propertyValuesHolder android:propertyName="alpha" >
          <keyframe
            android:fraction="0"
            android:value="1f" />
          <keyframe
            android:fraction=".5"
            android:value="0f" />
          <keyframe
            android:fraction="1"
            android:value="1f" />
        </propertyValuesHolder>
      </objectAnimator>
    </aapt:attr>
  </target>
  <target android:name="name2">
    <aapt:attr name="android:animation">
      <objectAnimator
        android:duration="2000"
        android:repeatCount="-1"
        android:repeatMode="reverse">
        <propertyValuesHolder android:propertyName="alpha" >
          <keyframe
            android:fraction="0"
            android:value="1f" />
          <keyframe
            android:fraction=".5"
            android:value="0f" />
          <keyframe
            android:fraction="1"
            android:value="1f" />
        </propertyValuesHolder>
      </objectAnimator>
    </aapt:attr>
  </target>
</animated-vector>

It seems I need to init it in the activity to set animation to work. But I did not find any tutorial about how to init it in Kotlin. Could anyone help me please?

Assuming there is an imageview with this vector drawable on it

ImageView imageView = view.findViewById(R.id.animatedImage);

AnimatedVectorDrawable drawable = (AnimatedVectorDrawable)imageView.getDrawable();

drawable.start(); //this starts the animation

drawable.setVisible(true,true); //this also starts the animation from start

It depends how you apply this Drawable. If it's set on an ImageView, you can use

(imageView.drawable as? Animatable)?.start()

If it's the background of a view you can use

(view.background as? Animatable)?.start()
