Android Twitter xAuth example using twitter4j

Question

Android: I am trying the following xAuth example for android share.

xAuth Authentication for Twitter Share in Android?

System.setProperty("twitter4j.oauth.consumerKey", "your token");
System.setProperty("twitter4j.oauth.consumerSecret", "your token secret");

Twitter twitter = new TwitterFactory().getInstance(login, password);

AccessToken accessToken = twitter.getOAuthAccessToken();
//Then you must save your Token and Token secret from AccesToken

if (mAccessToken != null) {
    if (mAccessToken.getToken() != null && mAccessToken.getTokenSecret() != null) {
        saveAccessToken(mAccessToken.getToken(), mAccessToken.getTokenSecret());
    }
}

I am having IllegalStateException

Exception Msg: java.lang.IllegalStateException: OAuth consumer key/secret combination not supplied

at the following line

AccessToken accessToken = twitter.getOAuthAccessToken();

I made changes some thing like following

Twitter twitter = new TwitterFactory().getInstance("login", "pass");
            twitter.setOAuthConsumer(getString(R.string.twtAPIKey), getString(R.string.twtSecret));
            AccessToken mAccessToken = twitter.getOAuthAccessToken();

and again I got exception Exception Msg: java.lang.IllegalStateException: Basic authenticated instance.

Any working example of xAuth ?

Answer 1

I ' ve used following

ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();

     configurationBuilder.setOAuthConsumerKey(Consumer__Key);
     configurationBuilder.setOAuthConsumerSecret(Consumer_Secret);
     Configuration configuration = configurationBuilder.build();

     Twitter twitter = new TwitterFactory(configuration).getInstance("username","password"); 

     AccessToken token = twitter.getOAuthAccessToken();
     System.out.println("Access Token " +token );

     String name = token.getScreenName();
     System.out.println("Screen Name" +name);

     PrintWriter out= response.getWriter();
     System.out.println(token);

And successfully login to Twitter using Android app using xauth

Version 2.2.2 of twitter4j as a slight change. This works:

Configuration configuration = new ConfigurationBuilder()
.setOAuthConsumerKey("your_customer_key")
.setOAuthConsumerSecret("your_customer_secret")
.build();

Twitter twitter = new TwitterFactory(configuration).getInstance(new BasicAuthorization(username, password)); // yes, use "BasicAuthorization" although that seems strange

AccessToken token = twitter.getOAuthAccessToken();
Log.d(TAG, "Access token: " + token.getToken());
Log.d(TAG, "Access token secret: " + token.getTokenSecret());

Remember that your twitter client application needs to be authorized to use xAuth before this works.
