     android.os.NetworkOnMainThreadException

    There’s your answer right there. You’re trying to access the network in the main UI thread. This is bad! See this article for guidance on how to avoid it.

    The article you linked to is setting a bad example by calling the send() method in a click handler. You may want to contact the author of that page to point out the problem.
