Twitter与Android的集成

我试图将twitter与我的应用在Android中集成。我试着在这里给出的androidHive指南http://goo.gl/VF4Pk Twitter与Android的集成

我每次点击登录按钮时都会收到下面的错误消息。

在这里，我得到的错误：

private void loginToTwitter() { 
    // Check if already logged in 
    if (!isTwitterLoggedInAlready()) 
    { 
     ConfigurationBuilder builder = new ConfigurationBuilder(); 
     builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY); 
     builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET); 
     Configuration configuration = builder.build(); 

     TwitterFactory factory = new TwitterFactory(configuration); 
     twitter = factory.getInstance(); 

     try { 
      requestToken = twitter 
        .getOAuthRequestToken(TWITTER_CALLBACK_URL); 
      this.startActivity(new Intent(Intent.ACTION_VIEW, Uri 
        .parse(requestToken.getAuthenticationURL()))); 
     } catch (TwitterException e) { 
      e.printStackTrace(); 
     } 
    } 

    else 
    { 
     // user already logged into twitter 
     Toast.makeText(getApplicationContext(), 
       "Already Logged into twitter", Toast.LENGTH_LONG).show(); 
    } 
}

更新1：

我的库文件更新到最新版本。现在，我可以在登录后获取登录屏幕，并接受它返回到我的应用程序的访问权限，但它始终显示登录错误 - NULL。看起来访问令牌没有得到更新或接受。

有人可以帮我吗？

谢谢！

这是第189行？请告诉我？ – Kishan

TwitterFactory factory = new TwitterFactory（configuration）; \t \t \t twitter = factory.getInstance（）; – TheDevMan

android.os.NetworkOnMainThreadException

你正在做UI（主）线程网络相关的操作。你必须在单独的工作者线程中做这件事，或者使用一个asynctask。

NetworkOnMainThreadException - Developers site

注：这只是抛出应用针对蜂窝SDK或更高。

更新1： 在你的情况下把代码获取请求令牌和的AsyncTask的doInBackground方法获取认证的URL。

我不知道我必须在哪里做asynctask部分？ – TheDevMan

无论你试图调用twitter4j方法，而twitter4j方法又调用api来通过互联网获取数据。 –

尝试了这一点，如果它的工作原理：

private void loginToTwitter() { 
// Check if already logged in 
if (!isTwitterLoggedInAlready()) 
{ 
    ConfigurationBuilder builder = new ConfigurationBuilder(); 
    builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY); 
    builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET); 
    Configuration configuration = builder.build(); 

    TwitterFactory factory = new TwitterFactory(configuration); 
    twitter = factory.getInstance(); 

    try { 

     new Thread(new Runnable() { 

      @Override 
      public void run() { 
       requestToken = twitter 
         .getOAuthRequestToken(TWITTER_CALLBACK_URL); 

       runOnUiThread(new Runnable() { 

        @Override 
        public void run() { 

         this.startActivity(new Intent(Intent.ACTION_VIEW, Uri 
            .parse(requestToken.getAuthenticationURL()))); 
        } 
       }); 

      } 
     }).start(); 



    } catch (TwitterException e) { 
     e.printStackTrace(); 
    } 
} 

else 
{ 
    // user already logged into twitter 
    Toast.makeText(getApplicationContext(), 
      "Already Logged into twitter", Toast.LENGTH_LONG).show(); 
} 
}

我仍然得到相同的错误。 – TheDevMan

把你的堆栈跟踪。 – Kishan
