Same here. When there is no connection... it's not caught

As per the Android Developer site (http://developer.android.com/training/basics/network-ops/connecting.html), you should establish the status of the connection prior to calling a http request.
I agree with the idea that this library could do this, but I don't feel it's an integral part of it. Checking connection status yourself will allow you to identify what type of connection is available etc.
Personally I wouldn't want this to be part of this package.

Fixed with #192

@smarek thank you 😄
