用Twitter编写奇怪的不受控制的异常

我对Scribe很新,但是当我尝试通过Twitter进行身份验证时,一个奇怪的错误就会上升.我的代码与TwitterExample完全相同:

        OAuthService service = new ServiceBuilder()
            .provider(TwitterApi.class)
            .apiKey("XXXXXXXXXXXXXX<>XXXXXXXXXXXXXXX")
            .apiSecret("YYYYYYYYYYYYYYYY<>YYYYYYYYYYYYYYYYYYYYYYYYY")
            .debug()
            .build();

        Token requestToken = service.getRequestToken();

        Log.i("OAUTH LINK", service.getAuthorizationUrl(requestToken));

        Verifier verifier = new Verifier("verifier you got from the user");
        Token accessToken = service.getAccessToken(requestToken, verifier);

        OAuthRequest request = new OAuthRequest(Verb.GET, PROTECTED_RESOURCE_URL);
        service.signRequest(accessToken, request);
        response = request.send();
        Log.i("OAUTH RESPONSE",response.getBody());

返回的调试输出是:

有人发现了这个错误吗？(对于新手来说一定是绝对的,但我找不到类似的东西......

谢谢!
