Twitter4J + Android:身份验证挑战是无效的

Question

我正在使用Twitter4J库进行OAuth身份验证,但即使在它打开Twitter登录页面之前,我也会收到"身份验证挑战是空的例外".

这是代码.

    Twitter twitter = new TwitterFactory().getInstance();
    try
    {

        twitter.setOAuthConsumer(Startup.TWITTER_KEY, Startup.TWITTER_SECRET);

        String callbackURL = "twitter-client:///";

        RequestToken rToken = twitter.getOAuthRequestToken(callbackURL);

        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(rToken.getAuthenticationURL())));

    }
    catch(IllegalStateException e)
    {
    // access token is already available, or consumer key/secret is not set.
        if(!twitter.getAuthorization().isEnabled()){
            System.out.println("OAuth consumer key/secret is not set.");
            System.exit(-1);
        }
    }
    catch(Exception e)
    {
        Toast.makeText(Home.this, "Network Host not responding: "+e.getMessage(),Toast.LENGTH_SHORT).show();  //This exception. 
    }

我有同样的问题.事实证明,如果oAuth调用上的时间戳不正确,服务器将返回401状态错误,在Android设备上会导致抛出"Received authentication challenge is null"异常.所有遇到此问题的设备都有不正确的时间,修复时间解决了问题.

也许这也是你的问题？
