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()

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

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?
