How to stop animation on the last frame?

Lottie in Mobile
1

Hi,

I have got a view like this:

        <com.lottiefiles.dotlottie.core.widget.DotLottieAnimation
            android:id="@+id/lottie_question"
            android:layout_width="70dp"
            android:layout_height="70dp"
            app:dotLottie_autoplay="true"
            app:dotLottie_loop="false"
            app:dotLottie_src="question.json"
            app:dotLottie_useFrameInterpolation="true"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

When the animation finishes, it disappears. I have tried the following code:

DotLottieAnimation anim = exitDialog.findViewById(R.id.lottie_question);
        anim.addEventListener(new DotLottieEventListener() {
            @Override
            public void onComplete() {
                anim.setFrame(anim.getTotalFrames());
            }
        });

However, my app freezes completely and I get the following error:

ANR in com.xyz.ang (com.xyz.ang/.activity.learning.QuizActivity)
                                                                                                    PID: 18191
                                                                                                    Reason: Input dispatching timed out (674e807 com.xyz.ang/com.xyz.ang.activity.learning.QuizActivity (server) is not responding. Waited 10000ms for MotionEvent).

After many attempts, I ended up using the freeze() function, which works exactly as I wanted.

            @Override
            public void onComplete() {
                anim.post(anim::freeze);
            }

Is there a simpler way to make the animation stay on the last frame after finishing, instead of having to use addEventListener(new DotLottieEventListener() { ... })?

I am using 0.12.0 version.
