我正在尝试使用twitter4j为我的应用程序连接并发布到Twitter.我关注
this tutorial.我已经从
here下载了示例项目并尝试在android 2.3.3上运行它.我确信我已经根据我的Twitter开发者网站正确修改了Constants.java文件.在TwitterUtils.java中,我也输入了OAUTH_TOKEN和OAUTH_TOKEN_SECRET.但运行后,我收到以下错误消息：

我不确定我是不是错了,在Constant.java中,我没有改变任何东西
public static final String REQUEST_URL = "https://api.twitter.com/oauth/request_token"; public static final String ACCESS_URL = "https://api.twitter.com/oauth/access_token"; public static final String AUTHORIZE_URL = "https://api.twitter.com/oauth/authorize"; public static final String OAUTH_CALLBACK_SCHEME = "x-oauthflow-twitter"; public static final String OAUTH_CALLBACK_HOST = "callback"; public static final String OAUTH_CALLBACK_URL = OAUTH_CALLBACK_SCHEME + "://" + OAUTH_CALLBACK_HOST;
我尝试用“http://www.MyWebsite.com”更改“回调”
请指教我如何纠正这些问题.
