Testing in Android Emulator

Please note Android Emulator has issues using `IPv6 addresses`. Executing any

socket related code (like this library) inside it will address an error

``` bash

java.net.SocketException: Bad address family

You have to manually disable `IPv6` by calling

``` java

java.lang.System.setProperty("java.net.preferIPv6Addresses", "false");

java.lang.System.setProperty("java.net.preferIPv4Stack", "true");

somewhere in your project, before instantiating the `WebSocketClient` class.

You can check if you are currently testing in the Android Emulator like this

``` java

if ("google_sdk".equals( Build.PRODUCT )) {

// ... disable IPv6

}
