android - 在 android 中集成 twitter 时出现异常

Question

我已经编写了将 Twitter 集成到 android 中的代码。因为我得到了第一个 scrren，当我写一些消息到 twitt 并单击 twitt 按钮时，我得到以下异常作为 OauthCommunication Exception 与服务通信提供商失败。我已正确输入消费者 key 消费者 secret 。

Public class MainActivity extends Activity {
    private static final String TAG = "TwitterDemo";
    private static final String CONSUMER_KEY = "xxx";
    private static final String CONSUMER_SECRET = "xxx";
    private static final String CALLBACK_SCHEME = "twitter-OAUTH-test-app";
    private static final String CALLBACK_URL = CALLBACK_SCHEME + "://callback";
    private static final String TWITTER_USER = "androidtestacc1@gmail.com";

    private OAuthSignpostClient oauthClient;
    private OAuthConsumer mConsumer;
    private OAuthProvider mProvider;
    private Twitter twitter;
    SharedPreferences prefs;

        prefs = PreferenceManager.getDefaultSharedPreferences(this);
        String token = prefs.getString("token", null);

尝试另一种方式在您的应用中整合 Twitter

1. 使用 auth 和 webview(Twitter4j 库)

http://davidcrowley.me/?p=410

http://www.mokasocial.com/2011/07/writing-an-android-twitter-client-with-image-upload-using-twitter4j/

代码(在 web View 中打开的 url)

   twitter =  new TwitterFactory().getInstance();
   twitter.setOAuthConsumer(TwitterConstants.CONSUMER_KEY,
        TwitterConstants.CONSUMER_SECRET);
    RequestToken requestToken = null;
    try {
        requestToken = twitter.getOAuthRequestToken();
        System.out.println("requesttoken"+requestToken);
    } catch (TwitterException e) {
        e.printStackTrace();
    }

    twitterUrl = requestToken.getAuthorizationURL();



    ConfigurationBuilder builder = new ConfigurationBuilder();
  builder.setOAuthAccessToken(TwitterConstants.ACCESS_TOKEN);
  builder.setOAuthAccessTokenSecret(TwitterConstants.ACCESS_TOKEN_SECRET);
  builder.setOAuthConsumerKey(TwitterConstants.CONSUMER_KEY);
  builder.setOAuthConsumerSecret(TwitterConstants.CONSUMER_SECRET);
  OAuthAuthorization auth = new OAuthAuthorization(builder.build());
  twitter = new TwitterFactory().getInstance(auth);

   try {
    twitter.updateStatus("Hello World!");

    } catch (TwitterException e) {
     System.err.println("Error occurred while updating the status!");

    }

2。单击按钮(未经授权)

            String message="";
            Intent i = new Intent(Intent.ACTION_VIEW);
            i.setData(Uri.parse("http://twitter.com/?status=" + Uri.encode(message)));
            startActivity(i);
