2016-09-27 11:00:57.857 [fatal][tid:com.facebook.react.RCTExceptionsManagerQueue] Unhandled JS Exception: handler is not a function. (In 'handler(rtn)', 'handler' is undefined). code is breaking in twilio app in index.js ](url)
addEventListener(type, handler) { _eventHandlers[type].set(handler, NativeAppEventEmitter.addListener( type, rtn => { handler(rtn); } )); },

The handler is your callback function. if it's undefined that means you don't have a callback function defined.

Twilio.addEventListener('deviceDidStartListening', () => { /*My callback handler here!*/ });

@somsin I'm getting the same error. Did you manage to solve? The app crashes, but my phone still rings!

@rogchap I have the same problem. The app crashes on connect in iOS, even in the RNTwilioExample app. Any pointers?

Checked again. It works fine on Android.

@jigyasam I've updated to latest SDK and fix some bit on android.
Try again with #27

Thanks @naviocean. I'll try it out and get back to you.
