Steps to Reproduce

This bug is not present on iOS. So, you have to run an Android Virtual Device (AVD) on Android 10. Here is a screenshot of my device : https://prnt.sc/s5rhpl

Then, you can try to run an application which uses lottie-react-native library.

Don’t forget to add this to your code :

<LottieView
          ref={animation => {
            this.animation = animation;
          }}
          style={{
            width: 400,
            height: 400,
          }}
          source={require('./assets/anim.json')}
        />

Expected Behavior

The application is not crashing…

Actual Behavior

Expo application is crashing with no error message, it can’t run the code.

Reproducible Demo

I created a repo that you can clone and run here : https://github.com/maxgfr/expo-lottie

Indeed, after exporting in V2 files, the android application doesn’t crash.

Nevertheless, it could be interesting to understand why lottie v3 is crashing on android only… Like this, we could fix the bug :p

Thanks for your message @byCedric and @mashuk999 !

Is there any way to export V3 files to V2 files when .JSON files has been downloaded from lottiefiles.com

I am wondering the same about converting animations - I have json files already and am wondering how to convert them
