Unable to retrieve data from Google Analytics (401 unauthorized access)

Question

I am trying to implement a basic data feed example, and all I get is simple:

com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized.

But when I use http://code.google.com/apis/analytics/docs/gdata/gdataExplorer.html
It works great with my Google Analytics account.

It seems that I did everything in accordance with the instructions of OAuth2: created a client identifier and a client secret, included the Analytics API.

I also tried to get my profiles and accounts with the Analytics management API, but I get the same error. What am I doing wrong?

Here is my code (of course, I run this code with the actual CLIENT_ID, CLIENT_SECRET and TABLE_ID):

public class AnalyticsTest { private static final String CLIENT_ID = "MY_CLIENT_ID"; private static final String CLIENT_SECRET = "MY_CLIENT_SECRET"; private static final String REDIRECT_URL = "urn:ietf:wg:oauth:2.0:oob"; private static final String APPLICATION_NAME = "test"; private static final String SCOPE = "https://www.googleapis.com/auth/analytics"; // TRIED AS WELL private static final String SCOPE = "https://www.google.com/analytics/feeds"; private static final String TABLE_ID = "MY_TABLE_ID"; public static void main(String[] args) throws IOException { NetHttpTransport netHttpTransport = new NetHttpTransport(); JacksonFactory jacksonFactory = new JacksonFactory(); // Generate the URL to send the user to grant access. String authorizationUrl = new GoogleAuthorizationRequestUrl(CLIENT_ID, REDIRECT_URL, SCOPE).build(); // Direct user to the authorization URI. System.out.println("Go to the following link in your browser:"); System.out.println(authorizationUrl); // Get authorization code from user. BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); System.out.println("What is the authorization code?"); String authorizationCode = null; authorizationCode = in.readLine(); // Use the authorization code to get an access token and a refresh // token. AccessTokenResponse response = null; try { response = new GoogleAccessTokenRequest.GoogleAuthorizationCodeGrant(netHttpTransport, jacksonFactory, CLIENT_ID, CLIENT_SECRET, authorizationCode, REDIRECT_URL).execute(); } catch (IOException ioe) { ioe.printStackTrace(); } // Use the access and refresh tokens to get a new // GoogleAccessProtectedResource. GoogleAccessProtectedResource googleAccessProtectedResource = new GoogleAccessProtectedResource(response.accessToken, netHttpTransport, jacksonFactory, CLIENT_ID, CLIENT_SECRET, response.refreshToken); Analytics analytics = Analytics .builder(netHttpTransport, jacksonFactory) .setHttpRequestInitializer(googleAccessProtectedResource) .setApplicationName(APPLICATION_NAME).build(); //System.out.println(analytics.management().accounts().list().execute()); Get apiQuery = analytics.data().ga().get(TABLE_ID, // "ga:" + Profile // Id. "2011-09-01", // Start date. "2011-12-23", // End date. "ga:visits"); // Metrics. try { GaData gaData = apiQuery.execute(); // Success. Do something cool! } catch (GoogleJsonResponseException e) { // Catch API specific errors. e.printStackTrace(); } catch (IOException e) { // Catch general parsing errors. e.printStackTrace(); } } 

Here is the stack trace:

Try changing the scope:

 private static final String SCOPE = "https://www.googleapis.com/auth/analytics"; 

:

 private static final String SCOPE = "https://www.googleapis.com/auth/analytics.readonly";
