Question

Hi I’m working on project, which has to access Google Docs. As example I’ve started from here
Currently I’m getting “401 Cannot parse AuthSub token”
I’ve looked into:

https://developers.google.com/google-apps/documents-list/

http://code.google.com/p/google-api-java-client/

Using Android AccountManager to get authtoken for gdata

And as I understand, android returns wrong type of access token. If there are any way to create valid access token for android using AccountManager, or I need to uses some other way of authentication?

import com.google.api.client.googleapis.extensions.android.accounts.GoogleAccountManager;
import com.google.api.services.docs.DocsClient;
import com.google.api.services.docs.DocsUrl;
import com.google.api.services.docs.model.DocumentListEntry;
import com.google.api.services.docs.model.DocumentListFeed;

public class Main extends ListActivity{
    private static final String AUTH_TOKEN_TYPE = "writely";
    private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
    protected DocsClient client;
    String accountName;


    GoogleAccountManager accountManager;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        client = new DocsClient(HTTP_TRANSPORT.createRequestFactory(credential));
        accountManager = new GoogleAccountManager(this);
        gotAccount();
    }

    void gotAccount() {

        accountManager.getAccountManager().getAuthToken(account, AUTH_TOKEN_TYPE, true, new AccountManagerCallback<Bundle>() {

          public void run(AccountManagerFuture<Bundle> future) {
            try {
              Bundle bundle = future.getResult();
              if (bundle.containsKey(AccountManager.KEY_INTENT)) {
                Intent intent = bundle.getParcelable(AccountManager.KEY_INTENT);
                intent.setFlags(intent.getFlags() & ~Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivityForResult(intent, REQUEST_AUTHENTICATE);
              } else if (bundle.containsKey(AccountManager.KEY_AUTHTOKEN)) {
                setAuthToken(bundle.getString(AccountManager.KEY_AUTHTOKEN));
                onAuthToken();
              }
            } catch (Exception e) {
              Log.e(TAG, e.getMessage(), e);
            }
          }
        }, null);
  }

void setAuthToken(String authToken) {
    credential.setAccessToken(authToken);
  }

 void onAuthToken() {
    List<String> result = new ArrayList<String>();
    DocumentListFeed feed = client.executeGetDocumentListFeed(DocsUrl.forDefaultPrivateFull());
    for (DocumentListEntry doc : feed.docs) {
            result.add(doc.title);
          }
    //DO something with list
  }
}

I’ve succeed in implementing this task. Had to switch to version 1.7 of google api client and uses

com.google.api.client.googleapis.auth.clientlogin.ClientLogin.Response

instead of

com.google.api.client.googleapis.auth.oauth2.GoogleCredential
