Unable to parse composition

Hi, guys. I have a crash on my release app. Crashes rarely happen, I can’t reproduce myself. Lottie version is v2.7.0. and it’s only happened in android 8.0 devices. Here is the log.

Check if you have the file perfectly. It can occur when the JSON file doesn’t exist.

I also have this crash,because I have two json files in raws and i load them in the same time,this will cause two threads operate one arrayList in the same time。so the solution is i load them by using LoadAnimationView.addLottieOnCompositionLoadedListeneadd to make sure load them in order!

I have the same usage with you–I have 3 LottieAnimationView loaded at the same time.But I didn’t find the reason why crash happend. So can you give more details? Thanks a lot anyway.

I also want to know why it crashed.
