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.

解决方法 您需要在更新ADT 17时将文件夹名称从lib更改为libs.
