add just the exception is in orange but probably you hyave got the exception bellow that takaki point out, follow the suggestion to pass through — Xenione, Sep 23 '13 at 11:28
you need to buid an script in the server side, I don't know if it's possible in your case, otherwise you are parsing a website that it may change and your app stops working — Xenione, Sep 23 '13 at 11:31

It will throw a NetworkOnMainThreadException if you call Jsoup.connect on the main thread.

Try using an AsyncTask to connect to the blog, retrieve the content, and then set it to display in the TextView.

See the selected answer here for a good example of this.

Also, don't forget to add the INTERNET permission to your manifest!

<uses-permission android:name="android.permission.INTERNET" />
