I'm closing this as the author states it cannot be reproduced. In general, debugging crashes shown in logs that can't be reproduced locally is not something that can be handled nicely here in this issue repo. I'm not saying the problem is not there - however I believe it's best to wait until this can be reproduced locally before opening an issue. Thanks for your understanding!
I'm also experiencing this issue. It seems to be already discussed on #13984.
Using LayoutAnimation on Android with react-native version prior to 0.45 is probably leading to this problem.
I am still seeing this issue in 0.49.3:-

This issue is closed, I recommend opening a new issue.
@hramos It's a random crash that occurs 10% of the time when called in the runApplication method in Libraries / ReactNative / AppRegistry.js锛宎nd I get a crash report that looks like this.

Any update? I'm on a recent fork done from wix master
