I want to enable server-side Calendar API access for my android app.
I have followed the steps given here .
I am getting a null value for the authorization code.
I think I am giving wrong values for 'scope' field and the 'server_client_id' field.
Please give me an example showing correct fields values for 'scope' and 'server_client_id' in the getToken() method.
Thanks for any help.
PS- I have used google+ sign in for android given here for connecting to a google account.
EDIT- Here is my code. I have given the OAuth 2.0 scope for the Google Calendar API in the scope field.
I have taken Client ID for Android application from Developers Console and put in 'serverClientID' field. This is probably where I am wrong. I don't know how to get Server's Client ID which is required by the
public class AsyncGetAuthToken extends AsyncTask<String, Void, String>{
#Override
protected String doInBackground(String... params) {
Bundle appActivities = new Bundle();
appActivities.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES,
"MainActivity");
String scopeString = "https://www.googleapis.com/auth/calendar.readonly";
String serverClientID = CLIENT_ID;
String scopes = "oauth2:server:client_id:" + serverClientID + ":api_scope:" + scopeString;
String code = null;
try {
code = GoogleAuthUtil.getToken(
MainActivity.this, // Context context
Plus.AccountApi.getAccountName(mGoogleApiClient), // String accountName
scopes, // String scope
appActivities // Bundle bundle
);
} catch (IOException transientEx) {
// network or server error, the call is expected to succeed if you try again later.
// Don't attempt to call again immediately - the request is likely to
// fail, you'll hit quotas or back-off.
return null;
} catch (UserRecoverableAuthException e) {
// Requesting an authorization code will always throw
// UserRecoverableAuthException on the first call to GoogleAuthUtil.getToken
// because the user must consent to offline access to their data. After
// consent is granted control is returned to your activity in onActivityResult
// and the second call to GoogleAuthUtil.getToken will succeed.
startActivityForResult(e.getIntent(), AUTH_CODE_REQUEST_CODE);
return null;
} catch (GoogleAuthException authEx) {
// Failure. The call is not expected to ever succeed so it should not be
// retried.
return null;
} catch (Exception e) {
throw new RuntimeException(e);
}
return null;
}
}
And in my onActivityResult, I look for the Auth Code
if (requestCode == AUTH_CODE_REQUEST_CODE) {
if (responseCode == RESULT_OK){
Bundle extra = intent.getExtras();
String oneTimeToken = extra.getString("authtoken");
Log.d("LOG", "one time token" + oneTimeToken);
}
}
I'm new to Android and GAE and trying to create a sample app. I was able to achieve insertEntity and listEntity. All is working fine. But when I tried to update an entity using updateEntity, it just doen't work. The android project doesn't even call backend gae. I'm sure I'm missing something very obvious thing here but not able to figure it out at all.
Here's my code of android app which calls update entity
private class ParentObjectUpdateTask extends AsyncTask<ParentObject, Void, UpdateParentObject> {
/**
* Calls appropriate CloudEndpoint to update
*
* #param params
* the object to update.
*/
#Override
protected UpdateParentObject doInBackground(ParentObject... params) {
ParentObject parentObj = params[0];
Parentobjectendpoint.Builder builder = new Parentobjectendpoint.Builder(
AndroidHttp.newCompatibleTransport(), new JacksonFactory(),
null);
builder = CloudEndpointUtils.updateBuilder(builder);
Parentobjectendpoint endpoint = builder.build();
UpdateParentObject updatedObj;
try {
updatedObj = endpoint.updateParentObject(parentObj);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
updatedObj = null;
}
return updatedObj;
}
#Override
protected void onPostExecute(UpdateParentObject result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
}
}
what about HttpRequestInitializer? Do I need to add PUT method here somehow?
Just to narrow down the scope, I'm working in local dev environment using Eclipse and nothing is deployed on GAE.
Change the line updatedObj = endpoint.updateParentObject(parentObj) to updatedObj = endpoint.updateParentObject(parentObj).execute(); to execute the Cloud Endpoint method.
I'm trying to create a spreadsheet via my android app. So far I've been only successful in creating an empty text document. Google's Spreadsheet API instructs me to follow Google Documents List API in order to create a spreadsheet document in Google Drive. In Google Documents List API it says:
To create a new, empty spreadsheet, follow the instructions in
Creating a new document or file with metadata only. When doing so, use
a category term of http://schemas.google.com/docs/2007#spreadsheet.
In the link above I've found the next .NET code:
using System;
using Google.GData.Client;
using Google.GData.Documents;
namespace MyDocumentsListIntegration
{
class Program
{
static void Main(string[] args)
{
DocumentsService service = new DocumentsService("MyDocumentsListIntegration-v1");
// TODO: Authorize the service object for a specific user (see Authorizing requests)
// Instantiate a DocumentEntry object to be inserted.
DocumentEntry entry = new DocumentEntry();
// Set the document title
entry.Title.Text = "Legal Contract";
// Add the document category
entry.Categories.Add(DocumentEntry.DOCUMENT_CATEGORY);
// Make a request to the API and create the document.
DocumentEntry newEntry = service.Insert(
DocumentsListQuery.documentsBaseUri, entry);
}
}
}
I've used this code to try and create a spreadsheet, but only the third variant worked (using DocsService, without adding Category and using feedUrl URL object).
Here's part of my working code (upload() is being called when user clicks a button):
private void upload() {
SpreadSheetAsyncTask sprdSheetAsyncTsk = new SpreadSheetAsyncTask();
sprdSheetAsyncTsk.execute();
}
public class SpreadSheetAsyncTask extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... params) {
spreadSheetService = new SpreadsheetService("Salary_Calculator");
docService = new DocsService("Salary_Calculator");
try {
spreadSheetService.setUserCredentials(USERNAME, PASSWORD);
docService.setUserCredentials(USERNAME, PASSWORD);
URL feedUrl = new URL(
"https://docs.google.com/feeds/default/private/full/");
URL tmpFeedUrl = new URL(
"https://spreadsheets.google.com/feeds/worksheets/key/private/full");
DocumentEntry entry = new DocumentEntry();
Calendar timeRightNow = GregorianCalendar.getInstance();
entry.setTitle(new PlainTextConstruct(
"Salary Calculator Spreadsheet "
+ timeRightNow.get(Calendar.DAY_OF_MONTH) + "/"
+ (timeRightNow.get(Calendar.MONTH) + 1) + "/"
+ timeRightNow.get(Calendar.YEAR)));
// Category object = new Category("spreadsheet",
// "http://schemas.google.com/docs/2007#spreadsheet");
//
//
// entry.getCategories().add(object);
/*
* TODO TEST AREA
*/
entry = docService.insert(feedUrl, entry);
/*
* TODO TEST AREA
*/
} catch (AuthenticationException e) {
cancel(true);
loginDialog("Wrong username or password");
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (ServiceException e) {
cancel(true);
loginDialog("Wrong username or password");
} catch (Exception e) {
loginDialog("Wrong username or password");
}
return null;
}
}
The non working code uses the category object object (as shown in the code comment) above and uses entry = spreadSheetService.insert(feedUrl, entry);
My question is - what did they want me to do when they wrote use a category term of http://schemas.google.com/docs/2007#spreadsheet?
We have contacted Google about this and we are on chat
The issue seems to be fixed for devices except Samsung phones.
I'm adding a Google+ sign in option to an app per the official instructions. Once the user has selected their account I would like my server to retrieve their Google+ profile info and update their profile on our site to match.
The first part - having the user select a Google account locally - seems to work just fine. When I try to request a token for the selected account, the Google auth dialog displays with the appropriate parameters; however, when I authorize the app using that dialog and re-request the token, GoogleAuthUtil.getToken(...) again throws a UserRecoverableAuthException (NeedPermission, not GooglePlayServicesAvailabilityException) and I get the same dialog asking me to approve!
This behavior is present on a Samsung S3 running Android 4.1.1 (with 3 Google accounts) and an Acer A100 running 4.0.3. It is NOT present on an HTC Glacier running 2.3.4. Instead, the HTC Glacier gives me a valid auth code. All devices have the latest iteration of Google Play Services installed and are using different Google+ accounts.
Anyone seen this before? Where can I start with debugging?
Here's the complete code - is anything obviously awry?
public class MyGooglePlusClient {
private static final String LOG_TAG = "GPlus";
private static final String SCOPES_LOGIN = Scopes.PLUS_LOGIN + " " + Scopes.PLUS_PROFILE;
private static final String ACTIVITIES_LOGIN = "http://schemas.google.com/AddActivity";
private static MyGooglePlusClient myGPlus = null;
private BaseActivity mRequestingActivity = null;
private String mSelectedAccount = null;
/**
* Get the GPlus singleton
* #return GPlus
*/
public synchronized static MyGooglePlusClient getInstance() {
if (myGPlus == null)
myGPlus = new MyGooglePlusClient();
return myGPlus;
}
public boolean login(BaseActivity requester) {
Log.w(LOG_TAG, "Starting login...");
if (mRequestingActivity != null) {
Log.w(LOG_TAG, "Login attempt already in progress.");
return false; // Cannot launch a new request; already in progress
}
mRequestingActivity = requester;
if (mSelectedAccount == null) {
Intent intent = AccountPicker.newChooseAccountIntent(null, null, new String[]{GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE}, false,
null, GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE, null, null);
mRequestingActivity.startActivityForResult(intent, BaseActivity.REQUEST_GPLUS_SELECT);
}
return true;
}
public void loginCallback(String accountName) {
mSelectedAccount = accountName;
authorizeCallback();
}
public void logout() {
Log.w(LOG_TAG, "Logging out...");
mSelectedAccount = null;
}
public void authorizeCallback() {
Log.w(LOG_TAG, "User authorized");
AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() {
#Override
protected String doInBackground(Void... params) {
String token = null;
try {
Bundle b = new Bundle();
b.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES, ACTIVITIES_LOGIN);
token = GoogleAuthUtil.getToken(mRequestingActivity,
mSelectedAccount,
"oauth2:server:client_id:"+Constants.GOOGLE_PLUS_SERVER_OAUTH_CLIENT
+":api_scope:" + SCOPES_LOGIN,
b);
} catch (IOException transientEx) {
// Network or server error, try later
Log.w(LOG_TAG, transientEx.toString());
onCompletedLoginAttempt(false);
} catch (GooglePlayServicesAvailabilityException e) {
Log.w(LOG_TAG, "Google Play services not available.");
Intent recover = e.getIntent();
mRequestingActivity.startActivityForResult(recover, BaseActivity.REQUEST_GPLUS_AUTHORIZE);
} catch (UserRecoverableAuthException e) {
// Recover (with e.getIntent())
Log.w(LOG_TAG, "User must approve "+e.toString());
Intent recover = e.getIntent();
mRequestingActivity.startActivityForResult(recover, BaseActivity.REQUEST_GPLUS_AUTHORIZE);
} catch (GoogleAuthException authEx) {
// The call is not ever expected to succeed
Log.w(LOG_TAG, authEx.toString());
onCompletedLoginAttempt(false);
}
Log.w(LOG_TAG, "Finished with task; token is "+token);
if (token != null) {
authorizeCallback(token);
}
return token;
}
};
task.execute();
}
public void authorizeCallback(String token) {
Log.w(LOG_TAG, "Token obtained: "+token);
// <snipped - do some more stuff involving connecting to the server and resetting the state locally>
}
public void onCompletedLoginAttempt(boolean success) {
Log.w(LOG_TAG, "Login attempt "+(success ? "succeeded" : "failed"));
mRequestingActivity.hideProgressDialog();
mRequestingActivity = null;
}
}
I've had this issue for a while and came up with a proper solution.
String token = GoogleAuthUtil.getToken(this, accountName, scopeString, appActivities);
This line will either return the one time token or will trigger the UserRecoverableAuthException.
On the Google Plus Sign In guide, it says to open the proper recovery activity.
startActivityForResult(e.getIntent(), RECOVERABLE_REQUEST_CODE);
When the activity returns with the result, it will come back with few extras in the intent and that is where the new token resides :
#Override
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
if (requestCode == RECOVERABLE_REQUEST_CODE && responseCode == RESULT_OK) {
Bundle extra = intent.getExtras();
String oneTimeToken = extra.getString("authtoken");
}
}
With the new oneTimeToken given from the extra, you can submit to the server to connect properly.
I hope this helps!
Its too late to reply but it may help to people having same concern in future.
They have mentioned in the tutorial that it will always throw UserRecoverableAuthException
when you invoke GoogleAuthUtil.getToken() for the first time. Second time it will succeed.
catch (UserRecoverableAuthException e) {
// Requesting an authorization code will always throw
// UserRecoverableAuthException on the first call to GoogleAuthUtil.getToken
// because the user must consent to offline access to their data. After
// consent is granted control is returned to your activity in onActivityResult
// and the second call to GoogleAuthUtil.getToken will succeed.
startActivityForResult(e.getIntent(), AUTH_CODE_REQUEST_CODE);
return;
}
i used below code to get access code from google.
execute this new GetAuthTokenFromGoogle().execute(); once from public void onConnected(Bundle connectionHint) and once from protected void onActivityResult(int requestCode, int responseCode, Intent intent)
private class GetAuthTokenFromGoogle extends AsyncTask<Void, Integer, Void>{
#Override
protected void onPreExecute()
{
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try {
accessCode = GoogleAuthUtil.getToken(mContext, Plus.AccountApi.getAccountName(mGoogleApiClient), SCOPE);
new ValidateTokenWithPhoneOmega().execute();
Log.d("Token -- ", accessCode);
} catch (IOException transientEx) {
// network or server error, the call is expected to succeed if you try again later.
// Don't attempt to call again immediately - the request is likely to
// fail, you'll hit quotas or back-off.
return null;
} catch (UserRecoverableAuthException e) {
// Recover
startActivityForResult(e.getIntent(), RC_ACCESS_CODE);
e.printStackTrace();
} catch (GoogleAuthException authEx) {
// Failure. The call is not expected to ever succeed so it should not be
// retried.
authEx.printStackTrace();
return null;
} catch (Exception e) {
throw new RuntimeException(e);
}
return null;
}
#Override
protected void onPostExecute(Void result)
{
}
}
I have got around this issue by using a web based login. I open a url like this
String url = "https://accounts.google.com/o/oauth2/auth?scope=" + Scopes.PLUS_LOGIN + "&client_id=" + webLoginClientId + "&response_type=code&access_type=offline&approval_prompt=force&redirect_uri=" + redirect;
The redirect url then handles the response and returns to my app.
In terms of my findings on using the Google Play Services, I've found:
HTC One is 3.1.59 (736673-30) - not working
Galaxy Note is 3.1.59 (736673-36) - not working
Nexus S is 3.1.59 (736673-34) - works
And I'd like to be involved in the chat that is occurring, however I don't have a high enough reputation to do so.
I've experienced the same issue recently - it appears to be device-specific (I had it happen every time on one S3, but on another S3 running the same OS it didn't happen, even with the same account). My hunch is that it's a bug in a client app, either the G+ app or the Google Play Services app. I managed to solve the issue on one of my devices by factory resetting it (a Motorola Defy), then reinstalling the Google Play Services app, but that's a completely useless solution to tell to users.
Edit (6th Aug 2013): This seems to have been fixed for me without any changes to my code.
The first potential issue I can see is that you are calling GoogleAuthUtil.getToken() after you get the onConnected() callback. This is a problem because requesting an authorization code for your server using GoogleAuthUtil.getToken() will always show a consent screen to your users. So you should only get an authorization code for new users and, to avoid showing new users two consent screens, you must fetch an authorization code and exchange it on your server before resolving any connection failures from PlusClient.
Secondly, make sure you actually need both a PlusClient and an authorization code for your servers. You only need to get a PlusClient and an authorization code if you are intending to make calls to the Google APIs from both the Android client and your server. As explained in this answer.
These issues would only result in two consent dialogs being displayed (which is clearly not an endless loop) - are you seeing more than two consent dialogs?
I had a similar problem where an apparent auth loop kept creating {read: spamming} these "Signing In..." and Permission request dialogs while also giving out the discussed exception repeatedly.
The problem appears in some slightly-modified example code that I (and other like me, I suspect) "cargo-culted" from AndroidHive. The solution that worked for me was ensuring that only one background token-retrieval task runs at the background at any given time.
To make my code easier to follow, here's the auth flow in my app (that is almost identical to the example code on AndoidHive): Activity -> onConnected(...) -> getProfileInformation() -> getOneTimeToken().
Here's where getOneTimeToken() is called:
private void getProfileInformation() {
try {
if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
Person currentPerson = Plus.PeopleApi
.getCurrentPerson(mGoogleApiClient);
String personName = currentPerson.getDisplayName();
String personPhotoUrl = currentPerson.getImage().getUrl();
String personGooglePlusProfile = currentPerson.getUrl();
String email = Plus.AccountApi.getAccountName(mGoogleApiClient);
getOneTimeToken(); // <-------
...
Here's my getOneTimeToken():
private void getOneTimeToken(){
if (task==null){
task = new AsyncTask<Void, Void, String>() {
#Override
protected String doInBackground(Void... params) {
LogHelper.log('d',LOGTAG, "Executing background task....");
Bundle appActivities = new Bundle();
appActivities.putString(
GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES,
ACTIVITIES_LOGIN);
String scopes = "oauth2:server" +
":client_id:" + SERVER_CLIENT_ID +
":api_scope:" + SCOPES_LOGIN;
String token = null;
try {
token = GoogleAuthUtil.getToken(
ActivityPlus.this,
Plus.AccountApi.getAccountName(mGoogleApiClient),
scopes,
appActivities
);
} catch (IOException transientEx) {
/* Original comment removed*/
LogHelper.log('e',LOGTAG, transientEx.toString());
} catch (UserRecoverableAuthException e) {
/* Original comment removed*/
LogHelper.log('e',LOGTAG, e.toString());
startActivityForResult(e.getIntent(), AUTH_CODE_REQUEST);
} catch (GoogleAuthException authEx) {
/* Original comment removed*/
LogHelper.log('e',LOGTAG, authEx.toString());
} catch (IllegalStateException stateEx){
LogHelper.log('e',LOGTAG, stateEx.toString());
}
LogHelper.log('d',LOGTAG, "Background task finishing....");
return token;
}
#Override
protected void onPostExecute(String token) {
LogHelper.log('i',LOGTAG, "Access token retrieved: " + token);
}
};
}
LogHelper.log('d',LOGTAG, "Task setup successful.");
if(task.getStatus() != AsyncTask.Status.RUNNING){
task.executeOnExecutor(AsyncTask.SERIAL_EXECUTOR); //double safety!
} else
LogHelper.log('d',LOGTAG,
"Attempted to restart task while it is running!");
}
Please note that I have a {probably redundant} double-safety against the task executing multiple times:
if(task .getStatus() != AsyncTask.Status.RUNNING){...} - ensures that the task isn't running before attempting to execute it.
task.executeOnExecutor(AsyncTask.SERIAL_EXECUTOR);- makes sure that copies of this task are "synchronized" (i.e. a queue is in place such that only one task of this type can executed at a given time).
P.S.
Minor clarification: LogHelper.log('e',...) is equivalent to Log.e(...) etc.
you should startactiviy in UI thread
try {
....
} catch (IOException transientEx) {
....
} catch (final UserRecoverableAuthException e) {
....
runOnUiThread(new Runnable() {
public void run() {
startActivityForResult(e1.getIntent(), AUTH_CODE_REQUEST);
}
});
}
Had the same bug with infinite loop of permission request. For me it was because time on my phone was shifted. When I check detect time automatically this bug disappeared. Hope this helps!
I want to show Facebook Page's Notes items with those comments and likes using Graph API.
To do that, I'm using the asyncFacebookRunner in Facebook SDK.
Steps are like this:
call asyncFacebookRunner.request to get Note Item with PageId
mAsyncRunner.request(sAPIString, new NotesRequestListener(), null);
Response has come. ( I can't highlight function call. Sorry for inconvenient to find it.)
public class NotesRequestListener implements com.facebook.android.AsyncFacebookRunner.RequestListener
{
/**
* Called when the request to get notes items has been completed.
* Retrieve and parse and display the JSON stream.
*/
#Override
public void onComplete(String response, Object state) {
// TODO Auto-generated method stub
Log.i("My_TAG", "onComplete with response, state");
try
{
// process the response here: executed in background thread
final JSONObject json = new JSONObject(response);
JSONArray arrNotesItems = json.getJSONArray("data");
int l = (arrNotesItems != null ? arrNotesItems.length() : 0);
// !!!!
// This has another request call
// !!!!
final ArrayList<WordsItem> newItems = WordsItem.getWordsItems(arrNotesItems,getActivity());
WordsActivity.this.runOnUiThread(new Runnable() {
public void run() {
wordsItems.clear();
wordsItems.addAll(newItems);
aa.notifyDataSetChanged();
}
}); // runOnUiThread
} // try
catch (JSONException e)
{
Log.i("My_TAG", "JSON Error in response");
} // catch
} // onComplete
... other override methods ...
} // Request Listener
< Another Class >
public static ArrayList<WordsItem> getWordsItems(JSONArray arrJSON, Activity activity) {
ArrayList<WordsItem> wordsItems = new ArrayList<WordsItem>();
int l = (arrJSON != null ? arrJSON.length() : 0);
try {
WordsItem newItem;
for (int i=0; i<l; i++) {
JSONObject jsonObj = arrJSON.getJSONObject(i);
String sTitle = jsonObj.getString("subject");
String sNoteID = jsonObj.getString("id");
... get another fields here ...
newItem = new WordItem(...);
// !!!!
// This has request call for comments
// !!!!
ArrayList<CommentItem> arrComment = getUserComments(sNoteID);
wordsItems.add(newItem);
}
} catch (Exception e) {
e.printStackTrace();
}
return wordsItems;
} // getWordsItems
call another asyncFacebookRunner.request to get comments of item(with NoteID)
in getUserComments
mAsyncRunner.request(sAPIString, new CommentRequestListener(), null);
Before getting comments(OnComplete in CommentRequestListener has not called), getWordsItems returns item array.
So I can't see the comments.
How can I wait to update UI till getting comments?
(It's so ironic to synchronize asynchronized calls.)
Thanks in advance.
Use facebook object which has non-asynchronous request method.
You need not implement listener method.
So, I suggest below means.
use mAsyncRunner.request for first request call.
use mFacebookRunner.request for second request call.
I hope it may help you:-)
Using FQL - Facebook Query Language you can easily get all this information about any particular note info
, Also to get likes on that and comments over it as like examples given in the links.
