Problem in Callback in Twitter in Android

Question

I have implemented Twitter in my application , i am facing problem in Callback.

Twitter API's has been updated recently so i am unable to send Callback URL.

Also the Setting Page now change there is No Option for Selecting Web Based application or Desktop Application.

If i send Callback in this Line :

authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URL);

It always returns

oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.

but if i send as Null in this its Redirecting to Twitter Login Page,but after successful Authorization it doesn't returns back to my Application.

After the Pin number is displayed i want to Redirect back to my Application.

Note : Twitter had updated their API so old Codes available in the Post is not working.

I tried all the Following Links

Link 1, Link 2, Link 3, Link4 , Link5 , Link 6

My Code is as follows :

public class Main extends Activity {
OAuthConsumer consumer;
OAuthProvider provider;
Twitter twitter;
private static  String CALLBACK_URL = "twitterapptest://connect";


@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    consumer = new DefaultOAuthConsumer(
            "XXXXXXXXXXX",
            "XXXXXXXXXXXXX");

    provider = new DefaultOAuthProvider(
            "https://api.twitter.com/oauth/request_token",
            "https://api.twitter.com/oauth/access_token",
            "https://api.twitter.com/oauth/authorize");

    String authUrl = null;
    try {
        authUrl = provider.retrieveRequestToken(consumer,null);
         this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
    } catch (OAuthMessageSignerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OAuthCommunicationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String pin = null;
    try {
        pin = br.readLine();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        provider.retrieveAccessToken(consumer, "4947222");
    } catch (OAuthMessageSignerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (OAuthCommunicationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    URL url = null;
    try {
        url = new URL("http://twitter.com/statuses/mentions.xml");
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    HttpURLConnection request = null;
    try {
        request = (HttpURLConnection) url.openConnection();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        consumer.sign(request);
    } catch (OAuthMessageSignerException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (OAuthExpectationFailedException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (OAuthCommunicationException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    try {
        request.connect();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        System.out.println("Response: " + request.getResponseCode() + " "
                + request.getResponseMessage());
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

                twitter = new TwitterFactory().getInstance();
                twitter.setOAuthConsumer("XXXXXXX", "XXXXXXXXXX");
                twitter.setOAuthAccessToken(a);

                // create a tweet

                Date d = new Date(System.currentTimeMillis());
                String tweet = "#OAuth working! " + d.toLocaleString();

                // send the tweet

                twitter.updateStatus(tweet);

            } catch (Exception e) {

Answer 1

The problem is that Callback URl. We should give one Dummy Callback URL in the Field Name of CallBack URL in Application' s Settings Page.

If we do like that and send the Call Back URL in our code, after successful Login there will be a option called Redirecting to your Application
