Tumblr Login in Android using SignPost

Question

I am trying to implement a tumblr login in my android app by following this example : https://github.com/jansanz/TumblrOAuthDemo.

i can get the request token . but when i'm trying to retrieve the AccessToken , it gives me an Exception. Here is the code :

public class TumblrDemoActivity extends Activity {

private static final String TAG = "TumblrDemo";

private static final String PREFS = "prefs_tumblr";
private static final String PREF_TOKEN = "pref_token_tumblr";
private static final String PREF_TOKEN_SECRET = "pref_token_secret_tumblr";

private static final String REQUEST_TOKEN_URL = "http://www.tumblr.com/oauth/request_token";
private static final String ACCESS_TOKEN_URL = "http://www.tumblr.com/oauth/access_token";
private static final String AUTH_URL = "http://www.tumblr.com/oauth/authorize";

// Taken from Tumblr app registration
private static final String CONSUMER_KEY = "consumer key from tumblr app";
private static final String CONSUMER_SECRET = "consumer secret from tumblr app";

private static final String CALLBACK_URL = "tumblrdemo://www.android-ios-tutorials.com";//"tumblrdemo://tumblrdemo.com/ok";

CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET); 
CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
        REQUEST_TOKEN_URL,
        ACCESS_TOKEN_URL,
        AUTH_URL);

SharedPreferences prefs;

String token;
String tokenSecret;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    prefs = getSharedPreferences(PREFS, Context.MODE_PRIVATE);
    consumer.setMessageSigner(new HmacSha1MessageSigner());
    // It uses this signature by default
    // consumer.setMessageSigner(new HmacSha1MessageSigner());

    // To get the oauth token after the user has granted permissions
    Uri uri = this.getIntent().getData();
    if (uri != null) {

        Log.d(TAG, "accessToken       : "+consumer.getToken());
        Log.d(TAG, "accessTokenSecret : "+consumer.getTokenSecret());

        //retrieve token and tokenSecret saved in retrieveRequestToken() call
        this.token = prefs.getString(PREF_TOKEN, null);
        this.tokenSecret = prefs.getString(PREF_TOKEN_SECRET, null);
        Log.d(TAG, "this.token       : "+token);
        Log.d(TAG, "this.tokenSecret : "+tokenSecret);

        consumer.setTokenWithSecret(token, tokenSecret);

        Log.d(TAG, "consumer.token       : "+consumer.getToken());
        Log.d(TAG, "consumer.tokenSecret : "+consumer.getTokenSecret());

        String token = uri.getQueryParameter("oauth_token");
        String verifier = uri.getQueryParameter("oauth_verifier");

        Log.v(TAG, "Token:" +token);
        Log.v(TAG, "Verifier:" +verifier);

        try {
            provider.retrieveAccessToken(consumer, verifier);
            Log.d(TAG, "accessToken       retrieveAccessToken    : "+consumer.getToken());
            Log.d(TAG, "accessTokenSecret retrieveAccessToken    : "+consumer.getTokenSecret());

        } catch (OAuthMessageSignerException e) {
            e.printStackTrace();
        } catch (OAuthNotAuthorizedException e) {
            e.printStackTrace();
        } catch (OAuthExpectationFailedException e) {
            e.printStackTrace();
        } catch (OAuthCommunicationException e) {
            e.printStackTrace();
        }
    } else {
        String authUrl;
        try {
            authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
            Log.v(TAG, "Auth url:" + authUrl);
            Log.d(TAG, "accessToken       : "+consumer.getToken());
            Log.d(TAG, "accessTokenSecret : "+consumer.getTokenSecret());

            //save tokens in preferences
            SharedPreferences.Editor editor = prefs.edit();
            editor.putString(PREF_TOKEN, consumer.getToken());
            editor.putString(PREF_TOKEN_SECRET, consumer.getTokenSecret());
            editor.commit();

            startActivity(new Intent("android.intent.action.VIEW", Uri.parse(authUrl)));

        } catch (OAuthMessageSignerException e) {
            e.printStackTrace();
        } catch (OAuthNotAuthorizedException e) {
            e.printStackTrace();
        } catch (OAuthExpectationFailedException e) {
            e.printStackTrace();
        } catch (OAuthCommunicationException e) {
            e.printStackTrace();
        }
    }
}

@Override
protected void onResume() {
    super.onResume();
    Log.v(TAG, "onResume");
}

}

the first call of provider.retrieveRequestToken() is OK. i can retrieve the token and the tokenSecret. but when i try to get accessToken by calling provider.retrieveAccessToken(consumer,oauth_verifier); i got an OAuthCommunicationException the stack trace of the OAuthCommunicationException is :

Answer 1

I have created a small library for Tumblr Login using oauth sign post and jumblr. you can find it here :

Tumblr Login API Using oauth sign post

I hope that this library will be helpfull for others who have the same issue.

Answer 2

I know this is a fairly old thread. But for anyone who comes in later.. I built a library to automate the login process. Besides, the link is broken Houcine. Might want to update that.

Its available on Github.
