How to log out a google account from an Android app

I am working on an Android app which uses google authentication.
I have this code segment:
try {
String token = GoogleAuthUtil.getToken(main, id, "oauth2:profile");
TRC.debug("google token=" + token);
return token;
} catch (UserRecoverableAuthException e) {
main.startActivityForResult(e.getIntent(), 15); // TODO const for 15
I would like to test the catch branch. When I've tried it first I got the google authentication Activity displayed. But when I tried it next time the UserRecoverableAuthException hadn't thrown.
How is it possible to force the app to log out from google?

How to properly integrate Pinterest in Android app?

I am using the REST API for integrating Pinterest into my Android app, but I'm getting an error when attempting to access categories.
My code:
String url = "https://api.pinterest.com/";
String allCategories = "/v2/boards/categories/";
RestClient client = new RestClient(url + allCategories);
String response = "";
try {
client.AddParam("limit", "36");
try {
client.Execute(RequestMethod.GET);
} catch (Exception e) {
e.printStackTrace();
}
response = client.getResponse();
} catch (Exception e) {
System.out.println(">>> Exception >>> " + e + " >>> Message >>> "
+ e.getMessage());
}
System.out.println(">>> response >>> " + response);
Log.d(">> Login response >>> ", response);
I'm getting the following error returned from the endpoint:
{
"message": "Please upgrade your app!",
"error": "Authentication failed: Please upgrade your app!"
}

Pinterest doesn't have any official api, and it's unofficial api is not working now. So I don't think your code will work any way, unless someone finds any other unofficial api or Pinterest releases the official version.
PS: More Info.

As of today, pinterest API has been taken down
(look here)
In the meantime you might want to use this 3rd party implemented scraper, which works just like an API
http://pinterestapi.co.uk/
You can use this to get the boards, likes and pins of a user.
Note: Curiously the count for the v1 api still works. But again this is undocumented behaviour and dont rely on this

Android - unable to use OAuth access token to retrieve Google Reader feeds

I need to obtain OAuth2 authentication token to pass it to the server so it can fetch list of Google Reader feeds for the user. Server is .NET - I have no access to it or to it's code but most likely it is using unofficial Reader API
I was able to use Android Account manager to obtain valid token for this purpose with the following code (notice that authTokenType="reader")
Account account = accounts[0];
manager.getAuthToken(account, "reader", null, this, new AccountManagerCallback<Bundle>() {
public void run(AccountManagerFuture<Bundle> future) {
try {
// If the user has authorized your application to use the tasks API
// a token is available.
String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
// Now you can send the token to API...
cacheManager.putString(GOOGLE_AUTH, token);
GoogleReaderManager.startAddFeedActivity(AddGoogleReaderSourcesActivity.this);
finish();
} catch (OperationCanceledException e) {
Log.e(TAG, "User cancelled", e);
finish();
} catch (Exception e) {
Log.e(TAG, "Failed to obtain Google reader API_KEY", e);
}
}
}, null);
The code above works fine when I send token to the server side .Net app: the app is able to retrieve the list of Reader feeds.
The problem is that this only works for "Google inside" devices. On Nook I have no such luck since there's no way that I was able to find to add Google account to the account manager. So I'm trying to it using OAuth 2 protocol as described here
It works fine as far as obtaining the token: User approves the app from the mobile page which returns the code token which then mobile app exchanges for the Auth token. However this token will not work with the server process. I have a feeling that perhaps I'm using the wrong scope in this URL:
https://accounts.google.com/o/oauth2/auth?response_type=code&scope=https://www.google.com/reader/api/0/subscription/list&redirect_uri=http://localhost&approval_prompt=force&state=/ok&client_id={apps.client.id}
Scopes that I did try in various combinations:
https://www.google.com/reader/api
https://www.google.com/reader/api/0
https://www.google.com/reader/api/0/subscription/list
https://www.google.com/reader/api+https://www.google.com/reader/atom
Here's example of JSON that is returned from get token POST
{"expires_in":3600,
"token_type":"Bearer",
"access_token":"ya29.AHES6ZSEvuUb6Bvd2DNoMnnN_UnfxirZmf_RQjn7LptFLfI",
"refresh_token":"1\/bUwa5MyOtP6VyWqaIEKgfPh08LNdawJ5Qxz6-qZrHg0"}
Am I messing up scope or token type? Not sure how to change a token type. Any other ideas?
P.S. Google account login page asks: Manage your data in Google Reader, that's why I suspect that the scope is wrong

I got it working for https://www.google.com/reader/api/0/subscription/list. So thought of sharing with you.
I have valid access_token:
This is what i tried to resolve it (partially) :
Google provides OAuth 2.o playgound; where they actually simulate all aspects of OAuth 2.0 as well as final API call to fetch data.
I found this very helpful as it clearly shows what is being sent to request.
Here is the URL : https://developers.google.com/oauthplayground/
Using this, i tweaked my api call below and it works :)
public static String getReaderContent(String accessToken){
String url = "https://www.google.com/reader/api/0/subscription/list" ;
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(url);
String response="";
method.setRequestHeader("Authorization", "OAuth "+accessToken);
try {
int statusCode = client.executeMethod(method);
String response= method.getResponseBodyAsString();
System.out.println("response " + responseStr);
} catch (HttpException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return response;
}
So this works properly fine for getting subscription list; but have not been able to make it work for reader api which you have mentioned in your question.
Let me know if you have got way around google reader API.

How to Integrate Twitter Oauth as like Facebook?

I am new to integrating Twitter. I have implemented Twitter in my application with this code:
// Create file
File picture = new File(APP_FILE_PATH + "/myAwesomeDrawing.png");
// Create TwitPic object and allocate TwitPicResponse object
TwitPic tpRequest = new TwitPic("username", "password");
TwitPicResponse tpResponse = null;
// Make request and handle exceptions
try {
tpResponse = tpRequest.uploadAndPost(picture, "Image Uploaded from My AndroidDrawing App...");
}
catch (IOException e) {
e.printStackTrace();
}
catch (TwitPicException e) {
e.printStackTrace();
}
// If we got a response back, print out response variables
if(tpResponse != null)
tpResponse.dumpVars();
All works fine here. But here I have to add the username and password programmatically. Is there any other way to use the Twitter integration as like Facebook OAuth to integration?
I need to know how Twitter OAuth is checked, and if the User is not login then it will ask for the username and password in its in built window.

fail to retrieve request token for yahoo integration in android?

I am trying to integrate yahoo in my app. I am trying,
private static final String YAHOO_CALLBACK_URI = "MyApp://oauth";
public static final String YAHOO_REQUEST_TOKEN_URL = "http://api.login.yahoo.com/oauth/request_token";//api.login.yahoo.com
public static final String YAHOO_ACCESS_TOKEN_URL = "http://api.login.yahoo.com/oauth/access_token";
public static final String YAHOO_AUTHORIZE_URL = "http://api.login.yahoo.com/authorize";
CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(YAHOO_CONSUMER_KEY, YAHOO_CONSUMER_SERECT_KEY);
OAuthProvider provider = new CommonsHttpOAuthProvider(YAHOO_REQUEST_TOKEN_URL, YAHOO_ACCESS_TOKEN_URL, YAHOO_AUTHORIZE_URL);
provider.setOAuth10a(true);
try {
String authUrl = provider.retrieveRequestToken(consumer, YAHOO_CALLBACK_URI);// Can I pass Null for callback url.
System.out.println("AuthURL = " + authUrl);
} catch (OAuthMessageSignerException e) {
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
e.printStackTrace();
} catch (OAuthCommunicationException e) {
e.printStackTrace();
}
getting
oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Service provider responded in error: 404 (Not Found)
Why we are unable to retrieve request token.

Make sure your app on Yahoo is registered as Web-Based. When you register as a Web-Based application, give a valid Application URL and App Domain of your choice (both should be the same domain), but has not been used by anyone else. I, for example, have the url of a website I own. This will also be used as the callback url in your consumer.
Instead of calling "MyApp://oauth", give a valid http callback url (the same one you used to register the app). With that much, your code above should work.
Open a new Webview and call the authUrl. Once your app is authorised, intercept the call to your application url by overriding the "onPageStarted" method. There, make a callback to your app by launching a new intent pointing to "MyApp://oauth".
Please let me know if any of the obove steps confuse you - I am more than happy to help.

I had followed the above mentioned 3#poits and able to do the call back to the application. The whole problem started with YAHOO OAUTH Process. Now Yahoo doesnt take the Custom Call back urls, It has to be a valid http url. n
There are couple of issues i have it which i am solving on my own,like Having a CUSTOMi Dialog box which can be used to call the Web-view YAHOO Auth URL similar to FB Dialog.
Thanks for the
