CallBack after Twitter Authentication

Question

I am trying to integrate twitter into my application but cannot make it work.

This is my code:

public class OAuthForTwitter extends Activity {

    private CommonsHttpOAuthConsumer httpOauthConsumer;
    private OAuthProvider httpOauthprovider;
    public final static String consumerKey = "xxxxxxxxxxxxxx";
    public final static String consumerSecret = "xxxxxxxxxxxx";
    private final String CALLBACKURL = "{removed}";
    private Twitter twitter;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        doOAuth();
    }

    /**
     * Opens the browser using signpost jar with application specific
     * consumerkey and consumerSecret.
     */

    private void doOAuth() {
        try {
            httpOauthConsumer = new CommonsHttpOAuthConsumer(consumerKey, consumerSecret);
            httpOauthprovider = new DefaultOAuthProvider(
                    "http://twitter.com/oauth/request_token",
                    "http://twitter.com/oauth/access_token",
                    "http://twitter.com/oauth/authorize");
            String authUrl = httpOauthprovider.retrieveRequestToken(httpOauthConsumer, CALLBACKURL);
            this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
        } catch (Exception e) {
            Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }

    @Override
    protected void onNewIntent(Intent intent) {

        super.onNewIntent(intent);

        Uri uri = intent.getData();
        if (uri != null && uri.toString().startsWith(CALLBACKURL)) {

            String verifier = uri
                    .getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);

            try {
                // this will populate token and token_secret in consumer

                httpOauthprovider.retrieveAccessToken(httpOauthConsumer,
                        verifier);

                // TODO: you might want to store token and token_secret in you
                // app settings!!!!!!!!

                AccessToken a = new AccessToken(httpOauthConsumer.getToken(),
                        httpOauthConsumer.getTokenSecret());

                // initialize Twitter4J

                twitter = new TwitterFactory().getInstance();
                twitter.setOAuthConsumer(consumerKey, consumerSecret);
                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) {

                Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
            }

        }
    }
}

When I finish authentication on Twitter, it should redirect me back to the application.

But instead, I get this page not found:

I have this in my AndroidManifest:

<intent-filter>  
        <action android:name="android.intent.action.VIEW"></action>  
        <category android:name="android.intent.category.DEFAULT"></category>  
        <category android:name="android.intent.category.BROWSABLE"></category>  
        <data android:scheme="sosInternational" android:host="HierBenIkNu"></data>  
    </intent-filter>  

How can I return to my application with the keys that I will receive back?

Answer 1

Well, that was a pretty dumb mistake.

My was <intent-filter>not inside the application.

Here's how to do it:

<activity 
        android:name=".OAuthForTwitter"
        android:label="@string/app_name"
        android:configChanges="orientation|keyboardHidden"
        android:launchMode="singleInstance">
        <intent-filter>  
            <action android:name="android.intent.action.VIEW"></action>  
            <category android:name="android.intent.category.DEFAULT"></category>  
            <category android:name="android.intent.category.BROWSABLE"></category>  
            <data android:scheme="sosInternational" android:host="OAuthForTwitter"></data>  
        </intent-filter>
    </activity>

This view works, it just loads the whole application from the very beginning.

There is no way to simply "go back" to the last action without restarting the entire application?

Your callback URL should be "sosInternational: // HierBenIkNu" (instead of "sosInternational: /// HierBenIkNu") in your Java code.

private final String CALLBACKURL = "sosInternational://HierBenIkNu";
