我不知道如果我错了，在Constant.java，我还没有在

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;

我试图改变回调与http://www.MyWebsite.com 请指点我该如何纠正这些问题。

I have tried changing "callback" with "http://www.MyWebsite.com" Please advice how can I correct these problems.
