react-native: [Android] `Cannot close WebSocket.` repeatedly

+1 with RN 0.44 and Firebase 3.9.0, both Android and iOS

+1 We are having A LOT of crashes in production! Is there any progress on this issue?

@jiyarong I have the following code in place:

    try {this.ws.close()} catch (e) {}
    this.ws = undefined

but I can still get the error.

@jiyarong the thing is that this error appears after network reconnect on ws.send(). This happens only on Android. iOS is good. The correct behaviour must be like on iOS: the application must go to websocket onError and there must be graceful websocket recreation. But the Android version just crashes.

Same. I get this issue both in debug and production releases on Google Play. I only get this issue on Android.

I’ve got a similar issue. After a network reconnect I’ve got this one:

On iOS there is no such error. I’ve got the app logic to close the websocket after network reconnect and open a new one. On iOS this logic works perfectly. But on Android I’ve this error. I guess the nature of this error is the same as in the original post. What are we going to do about it?

Similar Issue: RN : 0.42 Happens so often on remote debugging.

We’re using RN 0.43.4, Firebase 3.9.0 and experiencing this on Android only.
