I have issue with this line
https://github.com/facebook/react-native/blob/master/Libraries/WebSocket/WebSocket.js#L158

Why when ev.type === 'binary' you consider data as base64? Currently I have issue with android (There is no issue in ios with same message from server)

https://github.com/beatgammit/base64-js/blob/master/index.js#L23 throw this error Invalid string. Length must be a multiple of 4
