Animation takes a long time to "show"

I’m trying to show a dialog with an animation while the user waits for the AsyncTask to finish.

To achieve this, I used the following code (inside AsyncTask)?

protected void onPreExecute() {
super.onPreExecute();
    //Custom Dialog
    customDialog = new Dialog(mContext);
    customDialog.setContentView(R.layout.dialog_custom);
    customDialog.setTitle("Looking for address");

    //Custom Dialog Animation
    LottieAnimationView animationView = (LottieAnimationView) customDialog.findViewById(R.id.animation_view);
    animationView.setAnimation("PinJump.json"); //Lottie's premade animation
    animationView.loop(true);
    animationView.playAnimation();

    //Custom Dialog Text
    TextView text = (TextView) customDialog.findViewById(R.id.textView);
    text.setText(R.string.dialog_looking_for_address);
    customDialog.show();
}

The code above works wonderfully.

The only problem is that the animation takes about north of 1 second to show up. So I end up seeing the text way before the animation.

Is there anyway to make the animation show up as soon as the dialog is up? I tried casting the json file directly to the XML, but no dice, same thing happened.

@MegBasutkar05 The APIs have moved to LottieCompositionFactory

LottieComposition.Factory.fromAssetFileName is deprecated now. So is there an alternative way to go about it?
