android, oauth 1.0a, scribe = exception

I am getting these error when retrieving ucoz.api.ru (oauth 1.0a) token using scribe library oauth (4.2.0) on android :

Caused by: com.github.scribejava.core.exceptions.OAuthException: Response body is incorrect. Can't extract token and secret from this:

My source code:

  final OAuth10aService service = new ServiceBuilder(CONSUMER_KEY)
                .apiSecret(CONSUMER_SECRET)
                .debug()
                .build(UcozApi.instance());

        final Scanner in = new Scanner(System.in);
        // Obtain the Request Token
        final OAuth1RequestToken requestToken = service.getRequestToken(); // <<--- Error is in this place
        System.out.println(service.getAuthorizationUrl(requestToken));
        final String oauthVerifier = in.nextLine();
        // Trade the Request Token and Verfier for the Access Token
        OAuth1AccessToken accessToken = null;
        try {
            accessToken = service.getAccessToken(requestToken, oauthVerifier);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }

Ucozapi module:

public class UcozApi extends com.github.scribejava.core.builder.api.DefaultApi10a {

    private static final String AUTHORIZE_URL = "http://uapi.ucoz.com/accounts/oauthauthorizetoken=%s";
    private static final String REQUEST_TOKEN_RESOURCE = "http://uapi.ucoz.com/accounts/oauthgetrequesttoken";
    private static final String ACCESS_TOKEN_RESOURCE = "http://uapi.ucoz.com/accounts/oauthgetaccesstoken";

    protected UcozApi() {
    }

    private static final UcozApi INSTANCE = new UcozApi();


    public static UcozApi instance() {
        return INSTANCE;
    }

    @Override
    public String getAccessTokenEndpoint() {
        return ACCESS_TOKEN_RESOURCE;
    }

    @Override
    public String getRequestTokenEndpoint() {
        return REQUEST_TOKEN_RESOURCE;
    }

    @Override
    public String getAuthorizationUrl(OAuth1RequestToken requestToken) {
        return String.format(AUTHORIZE_URL, requestToken.getToken());
    }
}

Can somebody help me?

Solution

  • I answer my question. This code will work good with scribe-java library:

    MainActivity:

import com.github.scribejava.core.model.OAuth1AccessToken;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {
