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" />
