Hi, i get this crash from only Android 8 devices, app is on foreground (55% samsung):

I load the .json file from assets folder: app:lottie_fileName="filename.json". I am not sure which .json causes the problem, because there is not line number of my code. We have two <com.airbnb.lottie.LottieAnimationView/> in the same xml file. Only crashes on some random Android 8 devices.

From the stacktrace, it looks like error happens when it can not parse json file?, at this line.

For whatever reason, even if library can not parse it, can't we just fail softly instead of throwing RuntimeException? I would prefer empty, blank imageview instead of crash. Thanks

This error occurred when lottie.setAnimation(""); is not set or blank

This error also occurred when i wrote app:lottie_fileName="lottie_file_name" instead of app:lottie_fileName="main_load_bar.json"

This error also occurred when i wrote app:app:lottie_url="animation.json" instead of app:lottie_fileName="animation.json". Be careful :)
