I am trying to add LottieAnimationView to my xml layout in my project but getting this exception: "java.lang.IllegalStateException: Unable to parse composition".

Part of XML layout:

    <com.airbnb.lottie.LottieAnimationView
    android:id="@+id/animationView"
    android:layout_width="50dp"
    android:layout_height="50dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:lottie_autoPlay="true"
    app:lottie_loop="true"
    app:lottie_rawRes="@raw/heart_beat" />

What is interesting is that when I created a new test project and paste the above code to the newly created activity_main.xml everything works perfectly in the new project.

I tried to replase app:lottie_rawRes="@raw/heart_beat" with app:lottie_fileName="heart_beat.json" (from assets folder) but still no result. How can I resolve this issue? Thank you.

Solution

Got it. In build.gradle(Module:app) I excluded 'okio' and 'okhttp' modules for some reason. That leaded to the exception.

configurations {
    all*.exclude module: 'okhttp'
    all*.exclude module: 'okio'
}
