[android] java.lang.NullPointerException: Attempt to invoke virtual method

JanOwiesniak commented 5 years ago

I have not found the pattern yet. It seems to be non-deterministic and it's hard to reproduce but it happens from time to time. I'm not even 100% sure this is coming from react-native-unity-view but i though i might put it into an issue anyway. Maybe i'm not the only one running into this :)

I'm getting this same error and I don't have react-native-unity-view installed. @JanOwiesniak Are you using react-native-navigation?

@bpshonyak yes i was using react-native-navigation at this time but meanwhile changed to react-navigation. I have not seen this error in a long time, maybe this issue is related to react-native-navigation and not to react-native-unity-view.
