我不确定我是否错了，在 Constant.java 中，我没有在

am not sure if i am wrong, in Constant.java, i haven't change anything in

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;

我尝试将 "callback" 更改为 "http://www.MyWebsite.com"请建议我如何解决这些问题.
