在Android上使用Scribe OAuth Java库时出错

Question

I'm using Scribe library on android to get Flickr OAuth token.

I used the same example provided at

https://github.com/fernandezpablo85/scribe-java/blob/master/src/test/java/org/scribe/examples/FlickrExample.java

with System.out.println replaced with Log.d.

 private static final String PROTECTED_RESOURCE_URL = "https://api.flickr.com/services/rest/";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Replace these with your own api key and secret
        String apiKey = "xxxx989907fxxxxxxxxxxxxxxxxxxxx";
        String apiSecret = "fbxxxxx7dxxxxx8";
        OAuthService service = new ServiceBuilder().provider(FlickrApi.class).apiKey(apiKey).apiSecret(apiSecret).build();
        Scanner in = new Scanner(System.in);

        Log.d("","=== Flickr's OAuth Workflow ===");
        System.out.println();

        // Obtain the Request Token
        Log.d("", "Fetching the Request Token...");
        Token requestToken = service.getRequestToken();
        Log.d("", "Got the Request Token!");
        System.out.println();

        Log.d("", "Now go and authorize Scribe here:");
        String authorizationUrl = service.getAuthorizationUrl(requestToken);
        Log.d("", authorizationUrl + "&perms=read");
        Log.d("", "And paste the verifier here");
        Log.d("", ">>");
        Verifier verifier = new Verifier(in.nextLine());
        System.out.println();

        // Trade the Request Token and Verfier for the Access Token
        Log.d("", "Trading the Request Token for an Access Token...");
        Token accessToken = service.getAccessToken(requestToken, verifier);
        Log.d("", "Got the Access Token!");
        Log.d("", "(if your curious it looks like this: " + accessToken + " )");
        Log.d("", "(you can get the username, full name, and nsid by parsing the rawResponse: " + accessToken.getRawResponse() + ")");
        System.out.println();

        // Now let's go and ask for a protected resource!
        Log.d("", "Now we're going to access a protected resource...");
        OAuthRequest request = new OAuthRequest(Verb.GET, PROTECTED_RESOURCE_URL);
        request.addQuerystringParameter("method", "flickr.test.login");
        service.signRequest(accessToken, request);
        Response response = request.send();
        Log.d("", "Got it! Lets see what we found...");
        System.out.println();
        Log.d("", response.getBody());

        System.out.println();
        Log.d("", "Thats it man! Go and build something awesome with Scribe! :)");
    }

I get this error -

There was a problem while creating a connection to the remote service.

what is the problem here ?

For your Information:

The Network operations should not be used in the Main UI Thread. Do these operation as Background operation.

See AsyncTask in Android for more details. It solve the connection network problem. Hope this helps.
