Does anyone have a working example of OAuth authentication for twitter with Android? I have tried to use both Twitter4J and SignPost, but I get very strange errors, saying twitter.com is an unknown host. I have understod that there is a problem (under Google Android) with the SignPost library and Android and according to the project's home-page, the CommonsHttpOAuth* classes shall work.

Here is my SignPost:

private void getReqTokenAndAuthenticateUsingSignPost() {
    String callbackUrl = "twitter-test:///";
    CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY,
            CONSUMER_SECRET);
    CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
            "http://twitter.com/oauth/request_token", "http://twitter.com/oauth/access_token",
            "http://twitter.com/oauth/authorize");

    String tokenStr = consumer.getToken();
    String tokenSecretStr = consumer.getTokenSecret();

    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
    Editor edit = preferences.edit();
    edit.putString(REQ_TOKEN, tokenStr);
    edit.putString(REQ_TOKEN_SECRET, tokenSecretStr);

    try {
        String authUrl = provider.retrieveRequestToken(consumer, callbackUrl);
        Uri authenticationUri = Uri.parse(authUrl);
        startActivity(new Intent(Intent.ACTION_VIEW, authenticationUri));
    } catch (OAuthMessageSignerException e) {
        e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
        e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
        e.printStackTrace();
    } catch (OAuthCommunicationException e) {
        e.printStackTrace();
    }

}

and here is my code for Twitter4J:

private void getReqTokenAndAuthenticateUsingTwitter4J() {

    String callbackUrl = "twitter-test:///";
    try {
        // Prepare a request token, based on consumer key and consumer
        // secret
        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.setOAuthConsumerKey(CONSUMER_KEY);
        builder.setOAuthConsumerSecret(CONSUMER_SECRET);
        Configuration cfg = builder.build();
        Twitter t = new TwitterFactory(cfg).getInstance();

        RequestToken requestToken = t.getOAuthRequestToken(callbackUrl);
        String tokenStr = requestToken.getToken();
        String tokenSecretStr = requestToken.getTokenSecret();

        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        Editor edit = preferences.edit();
        edit.putString(REQ_TOKEN, tokenStr);
        edit.putString(REQ_TOKEN_SECRET, tokenSecretStr);
        if (edit.commit()) {
            // Launch the browser for authentication in twitter's web-gui
            Uri authenticationUri = Uri.parse(requestToken.getAuthenticationURL());
            startActivity(new Intent(Intent.ACTION_VIEW, authenticationUri));
        }
    } catch (TwitterException e) {
        e.printStackTrace();
    }
}

and yes, I have a manifest with Internet permission and an intent filter for the callback-url. Here is the output from logcat when running the SignPost code:

Have anybody resolved this? I'm stuck here. I can get the code to run as a Java SE program, but it fails on android...

Check and Confirm Two Things -

1-Give Callback URL in Your twitter app created by you on twitter website (Go to your app-> settings->callback url) Click here

2-Go to Phone settings then click 'Date and Time' and select 'Automatic' (Please make sure your device Time Zone and Time,Date all are correct) If your time,Date and Time Zone are not correct then you can not tweet.

I have a tutorial to setup OAuth for Twitter with Twitter4J on Android here, it includes the complete project source code to download as well - so that might help.

As for your specific issue - are you able to connect to the internet via the android emulator? it looks as though it is failing to connect - do you have any other apps on the emulator that attempt to connect the internet that you could try and test against? sometimes when I run the emulator if the internet connection fails then the signal bar on the emulator appears with an X by it and no-bars.

I'm an idiot. I copied my manifest from another project and mal-placed my permission tags. Doh. – Bloodhound
@Tarryn does your twitter oauth turoial work in versions 3.2 and up? Im experiencing problems getting my code to run in version 4.0 as android has added a new exception that doesn't allow any network tasks to be run on the ui thread anymore. – Forward

I've used SignPost in Android exactly for twitter client, works fine.

  1. Have you tried opening a browser in android and going to twitter.com?
  2. Try to connect to any url from the code?

Yes, I solved it (I wrote that above). I had messed up my manifest and spelled the internet permission bad. T
