jsoup not working on android

I have a problem with jsoup on android. I have seen the other posts and tried solutions that were suggested there ( re-adding the jars, calling android fix tool, etc.)

I have added the jsoup jar to my android project (using build path), and added the required internet permission to my manifest.

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

but when I am trying to run my application I am getting Could not find method org.jsoup.Jsoup.connect, referenced from method com.example.test.MainActivity.onCreate

I have tried to use the android fix tool but it did not solve the problem. All I have is a main activity and I am trying to call

Document doc = Jsoup.connect("http://en.wikipedia.org/").get();

attached is part of my code import org.jsoup.Jsoup; import org.jsoup.nodes.Document;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try {
            Document doc = Jsoup.connect("http://en.wikipedia.org/").get();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

Solution

You are trying to run your connection in your main thread. Use AsyncTask and it will work.

I.E.

public class JsoupParser extends AsyncTask...

Why you have to use AsyncTask for network connections in android?

AsyncTask is an abstract helper class that enables you to use the UI thread correctly, while performing background operations in a different thread, without having to really handle threads or controllers. Since android is implemented using a single thread model, each time you launch an application, a new thread will be created.

Imagine you have a single thread model where you at a button click will parse a website using Jsoup. This would have worked fine in earler android versions, though you would have had a non-responsive screen until the network operation is done. The AsyncTask will run in the background enabling your screen to still be responsive while another thread takes care of the network communication.

Take a look in the API:
AsyncTask
