We are trying to implement “lottie-6.4.0.aar” library to ATV11 application to AOSP android. App complied successfully but when loading JSON animation file we get following animation. Same error getting in Android Studio also.

In layout we add like below,

 <com.airbnb.lottie.LottieAnimationView
    android:id="@+id/lottieAnim1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:lottie_autoPlay="false"
    app:lottie_loop="true"
    app:lottie_rawRes="@raw/animation_sample_1"/>

Please help to solve this error.

After adding implementation ‘com.squareup.okio:okio:2.1.0’ dependencies the error is solved in Android Studio. We must add this dependencies ? if yes what is the solution for AOSP application (Android.mk).
