v1.1.1 (Fixes ConnectionEventListener null safety issue)
As seen here https://github.com/pusher/pusher-websocket-java/blob/master/src/main/java/com/pusher/client/connection/ConnectionEventListener.java
code and exception can be null.
This can be tested if while connected to pusher you close your internet connection. The error from the underlying websocket library has a null exception and code.
This issue was only for android.
Thanks to @spiritinlife for this PR.
