About how to pass the ParseObject(Object) using Rest API(service) in Installation class in android?

I am sagar, i am trying to implement the Parse Push-Notification in android using REST API (Service), and i am almost got success in implement the Push-Notification in Xamarin-Android using REST API. But i got stuck with one part in sending the Data into REST service. I trying to pass the ParseObject in service, but the in parse table there is a need of Object,(). I have tried to pass the ParseObject as below:
JsonConvert.SerializeObject(ParseUser.CurrentUser)
It convert ParseObject into array and array is not accepted in table and ,i got failed to save it in table. because there i a need of object.
I need solution or suggestion from developer guys. Yours help will be appreciated. I am trying the below code to achieve the result.
public static void RegisterPush(string regristrationId)
{
if (regristrationId != null) {
string appID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string restID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string masterID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
try {
var client = new RestClient ("https://api.parse.com");
var request = new RestRequest ("1/installations", RestSharp.Method.POST);
request.AddHeader ("Accept", "application/json");
request.AddHeader ("X-Parse-Application-Id", appID);
request.AddHeader ("X-Parse-REST-API-Key", restID);
request.Credentials = new NetworkCredential (appID, masterID);
request.Parameters.Clear ();
Console.Error.WriteLine ("ParseUser.CurrentUser-->"+ (ParseObject) ParseUser.CurrentUser);
//JsonConvert.SerializeObject(ParseUser.CurrentUser)
string strJSONContent = "{\"user\" :"+ JsonConvert.SerializeObject(ParseUser.CurrentUser)+",\"owner\":\"" + ParseUser.CurrentUser.ObjectId + "\",\"deviceType\":\"android\",\"GCMSenderId\":\"1234567890\",\"appName\":\"abcdefgh\",\"pushType\":\"gcm\",\"deviceToken\":\"" + regristrationId + "\"}";
Console.Error.WriteLine("json string-->"+ strJSONContent);
request.AddParameter ("application/json", strJSONContent, ParameterType.RequestBody);
client.ExecuteAsync (request, response => {
Console.Error.WriteLine ("response for android parse installation-->" + response.Content);
});
} catch (Exception ex) {
Console.WriteLine (ex.Message);
}
}
}`

Error:{"code":111,"error":"invalid type for key user, expected *_User, but got array"}

maven
I found the solution in , parse xamarin docs, in one query , the way is simple, but i little bit hard to found out.
The issue is with the data passing in json format in REST, to pass any pointer using REST API, use as below.
The solution is as below:
`{
"user":{
"__type":"Pointer",
"className":"_User",
"objectId":"qYvzFzGAzc"
},
"owner":"qYvzFzGAzc",
"deviceType":"android",
"GCMSenderId":"123456789",
"appName":"NiceApp",
"pushType":"gcm",
"deviceToken":"APA91bFeM10jdrCS6fHqGGSkON17UjEJEfvJEmGpRM-d6hq3hQgDxKHbyrqAIxMnEGgbLEZf0E9AllHxiQQQCdEFiNMF1_A8q0n9tGpBE5NKhvS2ZGJ9PZ7585puWqz_1Z1EjSjOvgZ1LQo708DeL2KzA7EFJmdPAA"
}`

It looks like your column user is set up wrong. It should show as a Pointer<_User> not Pointer
If you load this class in your Data Browser, is the "user" key defined as a string, or a Pointer <_User>
This error seems to indicate that this is a string column, which is why the Parse.User object is not being accepted as a valid value. You might have tried setting a string on this key before, which in turn type-locked the "user" key as a string column.
Found it on the examples given on this page - https://www.parse.com/docs/rest

Have you check your REST API connection while passing ParseObject?
Because your error says:
Error:{"code":111,"error":"invalid type for key user, expected *_User, but got array"}
Here "code":111This error code comes when server refuse for connection

Android can't retrieve data from web service using session ID

I'm a beginner of android programming. I had started a test project which is about using an android app to access web service and run function there. I am using ksoap2 to call the web services.
When I want to login to a database through phone and the web service return a session ID to me. But after that, When I want to run other function in service, and I pass it in session ID, it tell me that there is a null object reference. I tried use the session ID again to get back the login details but it shows that the session doesn't point to any session. This is the method which allow me to connect with web services. While for android, I just simply call using ksoap2.
<WebMethod(True)> _
Public Function CompanyConnectionString() As String
Dim lErrCode, lRetCode As Long
Dim sErrMsg As String = ""
Dim sSessionID As String = ""
Dim oCompany As SAPbobsCOM.Company
oCompany = New SAPbobsCOM.Company
// User and other details to connect
oCompany.Server = "xx.x.x.xx" //ip address
oCompany.DbServerType = SAPbobsCOM.BoDataServerTypes.dst_MSSQL2012
oCompany.DbUserName = "dbUser"
oCompany.DbPassword = "dbPassword"
oCompany.CompanyDB = "CompanyDB"
oCompany.UserName = "User"
oCompany.Password = "Password"
oCompany.LicenseServer = "xx.x.x.xx:xxxxx" // ip
lRetCode = oCompany.Connect
If lRetCode <> 0 Then
oCompany.GetLastError(lErrCode, sErrMsg)
sSessionID = lErrCode & "-" & sErrMsg
Else
sSessionID = Session.SessionID.ToString
Session.Add(sSessionID, oCompany)
''
Cookies.SetCookies(oCompany, "SID")
End If
Return sSessionID
End Function
I found that it might lose the session ID and I can't get back the login details for other functions later. So is that any idea for that? How I gonna do? without this I can't proceed further in my program.
Thank in advance..

Well, the problem had just solved. Me and my friend found out that that is because the sessionID is forgotten due to the max-age=0;. So we add that to our sessionID and it ran.
if (headerKey != null) {
if (headerKey.equals("Set-Cookie")) {
cookieBuilder.append(headerValue + "max-age=86400;");
}
} //headervalue is the sessionID
This will allow the session to stay active for 86400 seconds = 1 day.
So the sessionID can be use for running other function on web service

Google Plus Single Sign On Server Flow - Google_AuthException Error fetching OAuth2 access token, message: 'invalid_grant'

UPDATE 27th January 2013
I have now resolved this, Please check the accepted answer.
I am having trouble to get my refresh token and my access token when using the server side flow between my Android Application and my PHP server.
So I have managed to get my One Time Code by using the below:
AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() {
#Override
protected String doInBackground(Void... params) {
Bundle appActivities = new Bundle();
appActivities.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES,
"http://schemas.google.com/AddActivity");
String scopes = "oauth2:server:client_id:" + SERVER_CLIENT_ID +
":api_scope:" + SCOPE_STRING;
try {
code = GoogleAuthUtil.getToken(
OneTimeCodeActivity.this, // Context context
mPlusClient.getAccountName(), // 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.
System.out.println(transientEx.printStactTrace());
return "Error";
} catch (UserRecoverableAuthException e) {
// Recover
code = null;
System.out.println(e.printStackTrace());
OneTimeCodeActivity.this.startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
} catch (GoogleAuthException authEx) {
// Failure. The call is not expected to ever succeed so it should not be
// retried.
System.out.println(authEx.printStackTrace());
return "Error";
} catch (Exception e) {
System.out.println(authEx.printStackTrace());
}
}
Which will then store the token in the variable "code" and I call up the async task as
task.execute();
The code above will always bring up a popup message and throw UserRecoverableAuthException Need Permission that requires the user to grant offline access, which means the above will need to be called twice to retrieve the code and store it in "code"
I am now trying to send this across to my server which is implemented in PHP.
I have used the quick start https://developers.google.com/+/quickstart/php and managed to get that working.
In here, there is a sample signin.php
In here and according to the documentation this already implements a One Time Authorisation Server Side Flow.
So now my problem is sending this One Time Code to the server.
I used the photohunt Android Auth example for this located here.
https://github.com/googleplus/gplus-photohunt-client-android/blob/master/src/com/google/plus/samples/photohunt/auth/AuthUtil.java
I used the "authorization" method of the code and called up signin.php/connect through a post method shown below
$app->post('/connect', function (Request $request) use ($app, $client) {
$token = $app['session']->get('token');
if (empty($token)) {
// Ensure that this is no request forgery going on, and that the user
// sending us this connect request is the user that was supposed to.
if ($request->get('state') != ($app['session']->get('state'))) {
return new Response('Invalid state parameter', 401);
}
// Normally the state would be a one-time use token, however in our
// simple case, we want a user to be able to connect and disconnect
// without reloading the page. Thus, for demonstration, we don't
// implement this best practice.
//$app['session']->set('state', '');
$code = $request->getContent();
// Exchange the OAuth 2.0 authorization code for user credentials.
$client->authenticate($code);
$token = json_decode($client->getAccessToken());
// You can read the Google user ID in the ID token.
// "sub" represents the ID token subscriber which in our case
// is the user ID. This sample does not use the user ID.
$attributes = $client->verifyIdToken($token->id_token, CLIENT_ID)
->getAttributes();
$gplus_id = $attributes["payload"]["sub"];
// Store the token in the session for later use.
$app['session']->set('token', json_encode($token));
$response = 'Successfully connected with token: ' . print_r($token, true);
}
return new Response($response, 200);
});
Now when I send the code using the above implementation, I get an 500 messages that says the below
Google_AuthException Error fetching OAuth2 access token, message: 'invalid_grant'
in ../vendor/google/google-api-php-client/src/auth/Google_OAuth2.php line 115
at Google_OAuth2->authenticate(array('scope' => 'https://www.googleapis.com/auth/plus.login'), '{ "token":"xxxxxxxx"}') in ../vendor/google/google-api-php-client/src/Google_Client.php line 131

at Application->handle(object(Request)) in ../vendor/silex/silex/src/Silex/Application.php line 481
at Application->run() in ../signin.php line 139
Funny enough I have had to worked once where I did receive a 200, but I cannot recreate it.
So I know I have definitely got the implementation wrong, but I have no clue on how to send it and get my refresh token. I can't find anywhere on the web that explains this. Is someone able to help me please.
UPDATE 16 Jan 2014
Using https://www.googleapis.com/oauth2/v1/tokeninfo?access_token= I can see that the token being produced from getToken is valid and is indeed valid for 1 hour.
I can confirm the json formation is correct by changing the way I am inputting into the Post request and if I don't do it properly I get a total failure.
Now I am going deeper into the php and look at this section Google_OAuth2.php line 115 where it is breaking it is throwing a Google_AuthException. The code is below and this is provided in the quick starter pack
/**
* #param $service
* #param string|null $code
* #throws Google_AuthException
* #return string
*/
public function authenticate($service, $code = null) {
if (!$code && isset($_GET['code'])) {
$code = $_GET['code'];
}
if ($code) {
// We got here from the redirect from a successful authorization grant, fetch the access token
$request = Google_Client::$io->makeRequest(new Google_HttpRequest(self::OAUTH2_TOKEN_URI, 'POST', array(), array(
'code' => $code,
'grant_type' => 'authorization_code',
'redirect_uri' => $this->redirectUri,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret
)));
if ($request->getResponseHttpCode() == 200) {
$this->setAccessToken($request->getResponseBody());
$this->token['created'] = time();
return $this->getAccessToken();
} else {
$response = $request->getResponseBody();
$decodedResponse = json_decode($response, true);
if ($decodedResponse != null && $decodedResponse['error']) {
$response = $decodedResponse['error'];
}
throw new Google_AuthException("Error fetching OAuth2 access token, message: '$response'", $request->getResponseHttpCode());
}
}
$authUrl = $this->createAuthUrl($service['scope']);
header('Location: ' . $authUrl);
return true;
}
I edit the code above to make sure the code, the client id and secret were correct and they were. So that is where I am now, I don't think it is scope issues as well as I hard coded it in the client setup and still does not work. Not too sure.
UPDATE 23rd January
OK, I think it is a time issue. I used https://developers.google.com/+/photohunt/android and base my design on the BaseActivity in the Photohunt using the AuthUtil, and I get invalid grant on my server. How do I move the time back on my server in code. I read somewhere I can do time() - 10 somewhere but not sure where...

It sounds like you may be sending the same authorization code multiple times. On Android GoogleAuthUtil.getToken() caches any tokens that it retrieves including authorization codes.
If you ask for a second code without invalidating the previous code, GoogleAuthUtil will return the same code. When you try to exchange a code on your server which has already been exchanged you get the invalid_grant error. My advice would be to invalidate the token immediately after you retrieve it (even if you fail to exchange the code, you are better off getting a new one than retrying with the old one).
code = GoogleAuthUtil.getToken(
OneTimeCodeActivity.this, // Context context
mPlusClient.getAccountName(), // String accountName
scopes, // String scope
appActivities // Bundle bundle
);
GoogleAuthUtil.invalidateToken(
OneTimeCodeActivity.this,
code
);
invalid_grant can be returned for other reasons, but my guess is that caching is causing your problem since you said it worked the first time.

This issue is now resolved. This was due to the implementation on the One Time Code exchange with the server
As specified in the my issue above, I used the photohunt example to do the exchange with my server. The Android code can be found on the below link
https://github.com/googleplus/gplus-photohunt-client-android/blob/master/src/com/google/plus/samples/photohunt/auth/AuthUtil.java
One line 44 it reads this
byte[] postBody = String.format(ACCESS_TOKEN_JSON, sAccessToken).getBytes();
This will only work if on the server side you handle the JSON. I did not.
When calling up $client->authenticate($code); in php, $code had a JSON string and therefore when calling https://accounts.google.com/o/oauth2/token the authorization code was wrong.
So it was easy as I was not sending the code in the right format.
I found this out when digging and testing https://accounts.google.com/o/oauth2/token and created a manual cURL to test the token.
As provided in the Google+ API it was stated that all examples included a One Time Code exchange, but I think the code across all platform are not consistent and one has to double check themselve to make sure everything flows correctly, which was my mistake.

Using Amazon Webservices in android application

I have read on net tutorials that cloud can be used for storing data.So i wanted to ask that whether sql server 2005 table data be stored in amazon cloud.Can anyone give me the sample code to store data from sql server in amazon and retrieve it in android application?

Amazon gives you a server instance with the operating system specified by you. you can technically, install anything on it and host that.
What you should technically do is to take an instance of your desired specification from Amazon.
Write a simple web application (I would do a java webapp. For sure you can go for the same as you already are doing Android programming.) with connectivity to your DB and that has controllers to run your SQL queries and returns the values.
Here is some example code. This uses Spring just so you know. You can use plain MVC as well if you want do it simple to start with.
#RequestMapping ( value = "runquery" , method = RequestMethod.GET )
#ResponseBody
public void runQuery()
{
Statement lStatement = null;
Connection lConnection = null;
ResultSet lResultSet = null;
try
{
lConnection = DBAccess.getConnection();
lStatement = lConnection.createStatement();
lResultSet = lStatement.executeQuery( "select * from table" );
while ( lResultSet.next() )
{
mLogger.info("The result set is : "+lResultSet.toString());
}
}
catch( Exception e )
{
e.printStackTrace();
mLogger.error("Exception occurred while trying to runQuery : "+e.getMessage());
}
finally
{
DBAccess.closeResultSet( lResultSet );
DBAccess.closeStatement( lStatement );
DBAccess.closeDBConnection( lConnection );
}
}

How to send SharedObject Array data to PHP WS for DB Query (Flex)

I am currently developing an Android application using Flex 4.5.1 and I am having an issue when trying to pass data that I have stored in a SharedObject array to my Web Service for a Database query. the code below shows how I am storing the data in the SharedObject:
var so:SharedObject = SharedObject.getLocal("app");
public var prefsArray:ArrayCollection = new ArrayCollection(so.data.prefs);
protected function prefs_btn_click(event:MouseEvent):void
{
prefsArray.source.push(getFrsByIDResult.lastResult.id);
so.data.prefs = [prefsArray];
var flushStatus:String = so.flush();
if (flushStatus != null) {
switch(flushStatus) {
case SharedObjectFlushStatus.PENDING:
so.addEventListener(NetStatusEvent.NET_STATUS,
onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED:
trace("success");
break;
}
}
}
protected function onFlushStatus(event:NetStatusEvent):void
{
trace(event.info.code);
}
I have tested the SharedObject to see if the information is being entered into it correctly and all seems fine. Now I have used the code below in order to retrieve the data from the SharedObject and try and send it to the PHP web Service to run the DB query.
var so:SharedObject = SharedObject.getLocal("app");
var arrCol:ArrayCollection = new ArrayCollection(so.data.prefs);
var str:String = new String(arrCol.toString());
protected function list_creationCompleteHandler(event:FlexEvent):void
{
getPrefsByprefIdsResult.token = prefsService.getPrefsByPrefIds(so.data.prefs);
}
I have tested the Webservice in Flex and have it configured to recieve an Array of Ints (int[]) and it works when i run a test operation on it with two dummy values. However when I try to use the code above to pass the Web Service the Shared Object data I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert []#97e97e1 to mx.collections.ArrayCollection.

I have replaced certain filenames and locations with *'s to protect the work i am doing, but can someone please help me with this issues as I believe it has to be something simple???
Thanks
ok so let me explain in more detail. This is being designed for an Android app like I said, but image what I am trying to do is to store Bookmarks persistently using the Local Shared Object.
The first chunck of code you see above is designed to create the LSO attribute for the bookmark i want to create and imagine that there can be more than one bookmark set at different times like in a web browser. The only way i could find to do this was to store these items/details in an array which I retrieve and then update before saving back to the LSO and saving.
The second piece of code related to imagine a "Bookmarks Page" with a list of all the content that I have bookmarked. Now what I wanted to happen was thta I would be able to call up the LSO attribute which held the id's of the bookmarks and then load up thier details in a list format.
I have managed to create the LSO and store the bookmark deatils in and allow them to be updated and entries added. Also I have made sure that the PHP code that I have pulls back all the database objects relating to the array of id's and this has been tested using flex. The only thing that I cant seem to do is to pass the id's to the PHP web service file. The code in the Web Service file is below if that helps:
public function getPrefsByPrefIds($PrefIds) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE $this->tablename.id IN(" .implode(",", $PrefIds). ")");
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
$rows = array();
mysqli_stmt_bind_result($stmt, $row->id, $row->name, $row->desc);
while (mysqli_stmt_fetch($stmt)) {
$rows[] = $row;
$row = new stdClass();
mysqli_stmt_bind_result($stmt, $row->id, $row->name, $row->desc);
}
mysqli_stmt_free_result($stmt);
mysqli_close($this->connection);
return $rows;
}
Yes I had already tried that but thanks. I have made some more progress on my own as I have been experimenting with the different types of objects that can be stored in SharedObjects. I have managed to get the solution part working with this code:
This code is designed to capture the boomark info and store it in an arrayCollection before transferring it to a bytesArray and saving
var so:SharedObject = SharedObject.getLocal("app");
public var prefArray:ArrayCollection = new ArrayCollection(so.data.prefs);
protected function prefs_btn_click(event:MouseEvent):void
{
prefArray.source.push(getCompaniesByIDResult.lastResult.id);
so.data.prefs = [prefArray];
var bytes:ByteArray = new ByteArray();
bytes.writeObject(prefArray);
so.data.ac = bytes;
var flushStatus:String = so.flush();
if (flushStatus != null) {
switch(flushStatus) {
case SharedObjectFlushStatus.PENDING:
so.addEventListener(NetStatusEvent.NET_STATUS,
onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED:
trace("success");
break;
}
}
}
protected function onFlushStatus(event:NetStatusEvent):void
{
trace(event.info.code);
}
This next code is the designed to retrieve that information from the SahredObjects bytesArray and put it back into an Array Collection
var so:SharedObject = SharedObject.getLocal("app");
var ba:ByteArray = so.data.ac as ByteArray;
var ac:ArrayCollection;
protected function list_creationCompleteHandler(event:FlexEvent):void
{
ba.position = 0;
ac = ba.readObject() as ArrayCollection;
getPrefsByPrefIdsResult.token = prefsService.getPrefsByPrefIds(ac);
}
however as I have said this works in a small way only as if I store only one Bookmark (id) for an item and then go to the bookmarks list the details for that bookark are successfully retrieved, however if I save more than one Bookmark(2 or more id's) the page will not load the details, i do not get an error but I believe it is hanging because it is looking for say id's "1,2" instead of "1" and "2" but i dont know why this is or how to resolve this. I appreciate the advice I have been given but am finding it hard there is no one who can help me with this issue and I am having to do various experiemnts with the code. Can someone please help me with this I would really appreciate it :-) Thanks
