Facebook Component in QML

2012-01-22T00:45:00.001-08:00

Hello friends,

Lets learn some Qt and QML stuff today. And the good part its quite interesting too.

Many of the mobile applications now a days have a feature where user need to share about the application on various social networks, and we all know Facebook is one of the kings of Social Networks.

This article will simply help the developers to learn how to use Facebook With QML, or in simple sense it will simple help developers to get authenticate the user with Facebook.

Now authentication process in facebook happens in something called as OAuth v2 which is quite easy from the OAuth v1.x which is currently used by many of social networks including twitter.

In OAuth v2 everything happens at the url and developer can get the access token from the changing url itself.

While doing authentication in Facebook , the most important thing is Access Token, this is the token you require to make all sort of api calls in Facebook. I think this is much of talking lets get to the action now.

To make the life of developers easy i have made this component using basic QML Webview, which developers can use in Symbian, Meego and other desktop platforms too.

One more thing i have just written this code in a hour so to make it might not be a complete component but you can obviously make it like the way you want. :-)

Facebook.qml

 /*  
  Simple facebook component which launches a webview with facebook authetication url  
  This also extracts the access token and to be used in accessing the graph api on later part  
  */  
 import Qt 4.7  
 import QtWebKit 1.0  
 /*  
  * Facebook qml class implements all facebook properties and functions for using facebook.  
  */  
 WebView {  
   id: fbauthdialog  
   property string accesstoken  
   property string fb_clientid  
   property string fb_redirecturl:"http://www.facebook.com/connect/login_success.html"  
   property string fb_display:"wap"  
   property string fb_responsetype:"token"  
   property string fb_user_permissions  
   signal urlLoadStarted()  
   signal urlLoadFinished()  
   signal urlLoadFailed()  
   signal authenicationCompleted()  
   signal errorOccured()  
   function customLogfunction(msg){  
     console.log("[Facebook Example]"+msg)  
   }  
   /**  
    Simple javascript function which checks if Access Token is present in the url or not  
    Is called by the Webview component when the URL is completely loaded  
    */  
   function checkforaccesstoken(url){  
     if(url.search("access_token") != -1)  
     {  
       customLogfunction("access_token is present")  
       var indexofequal = url.indexOf("=");  
       var indexofExpire = url.indexOf("&expires_in");  
       // parse the access token & save it in a property  
       customLogfunction("Indexof equalto = "+indexofequal+" index of expires in = "+indexofExpire)  
       fbauthdialog.accesstoken = url.substring(indexofequal+1,indexofExpire);  
       customLogfunction("Access Token = "+fbauthdialog.accesstoken);  
       // fire the signal of authentication complete  
       fbauthdialog.authenicationCompleted()  
     }  
   }  
   anchors.fill: parent  
   url:"https://www.facebook.com/dialog/oauth?client_id="+fb_clientid+"&redirect_uri="+fb_redirecturl+"&display="+fb_display+"&response_type="+fb_responsetype+"&scope="+fb_user_permissions  
   onLoadStarted:{  
     console.log("load started with url:" + url)  
     fbauthdialog.urlLoadStarted()  
   }  
   onLoadFailed: {  
     console.log("load failed with url:" + url)  
   }  
   onLoadFinished: {  
     console.log("load finished with url:"+url)  
     checkforaccesstoken(url.toString())  
     fbauthdialog.urlLoadFinished()  
   }  
 }

The Component is quite simple, it loads a Facebook Authentication Dialog, and calls a function everytime a url is loaded, there is checks for the access token, once the correct url is loaded the access token is parsed and saved into a property so that you can use it later.

So now lets see how we can use this component, its quite simple actually, following code does that with using Page and BusyIndicator of Qt Quick Components.

 import QtQuick 1.0  
 import com.nokia.symbian 1.0  
 Page{  
   id:fbauthpage  
   Facebook{  
     id:facebook  
     fb_clientid: "233061016747529"  
     fb_display: "wap"  
     fb_user_permissions:"user_about_me,publish_stream"  
     BusyIndicator{  
       id:mainBusyIndicator  
       anchors.centerIn: facebook  
       opacity: 0  
     }  
     onUrlLoadStarted: {  
         mainBusyIndicator.opacity = 1  
         mainBusyIndicator.running = true  
     }  
     onUrlLoadFinished: {  
         mainBusyIndicator.opacity = 0  
         mainBusyIndicator.running = false  
     }  
     onAuthenicationCompleted: {  
       pageStack.pop()  
     }  
   }  
 }

I guess that's it, one thing you need to keep in mind that the new Facebook access token doesnt have the userid :-(, so once you get your access token you need to make a http get request to get the user id and then use it.

Please let me know your comments about this article.

Uploading Image In Android

2012-01-15T06:13:00.000-08:00

Hello all,

As promised in one of the previous articles, this article will explain about how to use Android AsyncTask to upload images to remote web server on android.

Now to make this task simpler and more useful i have designed one class named ImageUploaderUtility, which uploads images to a remote webserver. ImageUploadUtility has simple methods where you just need to pass the name of your image to upload.

Apart from this the key point here is this class needs to be executed in an AsynTask so it ensures the whole image upload process doesn't freeze your UI.

I have used this same past project and expanded it.

The first thing to understand is i have made inner class in my BlogPostExampleActivity which is extended from AsyncTask, this inner class will call the method to upload image which is declared and defined in ImageUploader Utility that's all isn't that simple.

Have a look at the code and let me know if you can't understand anything in this.

  private class ImageUploaderTask extends AsyncTask<String, Integer, Void> {
 @Override
 protected void onPreExecute(){
  simpleWaitDialog = ProgressDialog.show(BlogPostExamplesActivity.this, "Wait", "Uploading Image");
 }
 @Override
 protected Void doInBackground(String... params) {
  new ImageUploadUtility().uploadSingleImage(params[0]);
  return null;
 }
 @Override
 protected void onPostExecute(Void result){
  simpleWaitDialog.dismiss();
 }
}

And Now ImageUploaderUtility.java

 package gargi.blogpostexamples.webservice;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.httpclient.methods.PostMethod;

import android.util.Log;
class ImageUploadUtility {
/**
 * Simple Utility Method gets called from other class to start uploading the image
 * @param fileNameToUpload name of the file to upload
 */
public void uploadSingleImage(String fileNameToUpload){
  try {
  doUploadinBackground(getBytesFromFile(new File(Environment.getExternalStorageDirectory(),fileNameToUpload)), fileNameToUpload);
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 } catch (Exception e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
}
/**

 * We are not using the default httpclient coming with android we are using the new from apache
 * they are placed in libs folder of the application
 *
 * @param imageData

 * @throws Exception
 */
static boolean doUploadinBackground(final byte[] imageData, String filename) throws Exception{
   String responseString = null;
   PostMethod method;
   method = new PostMethod("your url to upload");
       org.apache.commons.httpclient.HttpClient client = new org.apache.commons.httpclient.HttpClient();
       client.getHttpConnectionManager().getParams().setConnectionTimeout(
               100000);
       FilePart photo = new FilePart("userfile", new ByteArrayPartSource(
           filename, imageData));
       photo.setContentType("image/jpeg");
       photo.setCharSet(null);
       String s  =  new String(imageData);
       Part[] parts = {
               new StringPart("latitude", "123456"),
               new StringPart("longitude","12.123567"),
               new StringPart("imei","1234567899"),
               new StringPart("to_email","some email"),
               photo
               };
       method.setRequestEntity(new MultipartRequestEntity(parts, method
               .getParams()));
       client.executeMethod(method);
       responseString = method.getResponseBodyAsString();
       method.releaseConnection();
       Log.e("httpPost", "Response status: " + responseString);
   if (responseString.equals("SUCCESS")) {
       return true;
   } else {
       return false;
   }
 }
/**
 * Simple Reads the image file and converts them to Bytes
 *
 * @param file name of the file
 * @return byte array which is converted from the image
 * @throws IOException
 */
public static byte[] getBytesFromFile(File file) throws IOException {
  InputStream is = new FileInputStream(file);
  // Get the size of the file
  long length = file.length();
  // You cannot create an array using a long type.
  // It needs to be an int type.
  // Before converting to an int type, check
  // to ensure that file is not larger than Integer.MAX_VALUE.
  if (length > Integer.MAX_VALUE) {
    // File is too large
  }
  // Create the byte array to hold the data
  byte[] bytes = new byte[(int)length];
  // Read in the bytes
  int offset = 0;
  int numRead = 0;
  while (offset < bytes.length
      && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
    offset += numRead;
  }
  // Ensure all the bytes have been read in
  if (offset < bytes.length) {
    throw new IOException("Could not completely read file "+file.getName());
  }
  // Close the input stream and return bytes
  is.close();
  return bytes;
}
}

So that's it for now, the bad thing in this is i have used to Inner Class in this activity and i don't know why but i am not feeling good about that, so next time i will try to make a single class extended from AysncTask and use that in existing examples.

Apart from this if you feel it can be improved in some other ways please don't forget to leave that in comment.

Last but not the list you can download the complete example from this link.

Have a Good Week ahead,

How to ignore SSL Error to get https website working on QML Webview

2012-01-13T21:11:00.000-08:00

Exact Problem & Reason for the problem

Many of our day to day application development requires us to use QML Webview and open some https website over there for transferring some secured content, in some most of the Symbian^3 devices, there's a problem with this activity.

Most of the times QML Webview fires onLoadFailed signal whenever we try to open any of the https based website. For example this link https://identi.ca/api/oauth/authorize is used during implementing OAuth to access the services of identi.ca, but everytime you try to open this url in QML Webview it will always give you an onLoadFailed error.

The Main reason behind above phenomenon is that , the missing or invalid certificate on the symbian^3 device which causes this SSL error, hence QML Webview fires the onLoadFailed signal.

Solution

This blog post will explain how to tackle the situation explained above, the problem is solved by simply bypassing the warnings which are caused due to the missing SSL certificate. This can be done by providing our own custom QNetworkAccessManager to the QML Declarative Engine which ignores the ssl errors.

Code Snnippet

Following class explains how we can create our own QNetworkAccessManager, and how we can make the QDeclarativeEngine to use that QNetworkAccessManager. Apart from this our own QNetworkAccessManager also takes care of ignoring the SSL errors.

customnetworkmanagerfactory.h

 #include <QObject>  
 #include <QNetworkAccessManager>  
 #include <QNetworkReply>  
 #include <QSslError>  
 // need to derive your class from QDeclarativeNetworkAccessManagerFactory, Our class is derived also from QObject  
 // the reason is to use signal and slot mechanism   
 class CustomNetworkManagerFactory : public QObject,public QDeclarativeNetworkAccessManagerFactory  
 {  
   Q_OBJECT  
 public:  
   explicit CustomNetworkManagerFactory(QObject *parent = 0);  
   virtual QNetworkAccessManager *create(QObject *parent);  
 public slots:  
   void onIgnoreSSLErrors(QNetworkReply* reply,QList<QSslError> error);  
 private:  
   QNetworkAccessManager* m_networkManager;  
 };

customnetworkmanagerfactory.cpp

 #include "customnetworkmanagerfactory.h"  
 CustomNetworkManagerFactory::CustomNetworkManagerFactory(QObject *parent) :  
   QObject(parent)  
 {  
 // nothing to be done on the constructor  
 }  
  /**  
 this is a virtual method we need to implement this method , most important step  
 we will create our custom QNetworkAccessManager here and return that   
 the second important thing we need to do here is to connect the sslErrors signal from QNetworkAccessManager to our own slot  
 which will ignore the sslErrors  
 */  
 QNetworkAccessManager* CustomNetworkManagerFactory::create(QObject *parent)  
 {  
   m_networkManager = new QNetworkAccessManager(this);  
   connect(m_networkManager,SIGNAL(sslErrors(QNetworkReply*,QList<QSslError>)),this,SLOT(onIgnoreSSLErrors(QNetworkReply*,QList<QSslError>)));  
   return m_networkManager;  
 }  
 /**  
 Our own slot which is connected to the sslErrors signal of QNetworkAccessManager  
 When this slot is called using the QNetworkReply object in the parameter we need to call ignoreSslErrors method of QNetworkReply  
 */  
 void CustomNetworkManagerFactory::onIgnoreSSLErrors(QNetworkReply *reply, QList<QSslError> error)  
 {  
   reply->ignoreSslErrors(error);  
 }

once this class is complete we need to make sure that the QDeclarativeEngine uses the custom QDeclarativeNetworkAccessManagerFactory we have designed above, to do that please check the main.cpp file implementation below:

 #include "customnetworkmanagerfactory.h"  
 int main(int argc, char *argv[])  
 {  
   QApplication app(argc, argv);  
   // declare and intialize your custom network manager factory  
   CustomNetworkManagerFactory* myNetworkAccessManagerFactory = new CustomNetworkManagerFactory(&app);  
   // QDeclarativeEngine Interface provided by application template  
   QmlApplicationViewer viewer;  
   //set our customnetworkmanagerfactory on the declarative engine  
   viewer.engine()->setNetworkAccessManagerFactory(myNetworkAccessManagerFactory);  
   return app.exec();  
 }

Once the developer successfully completes this then there opening https websites will not be a problem

Using AsyncTask In android

2012-01-06T09:28:00.001-08:00

Hello all,

One of my current application in android, required me to upload and download an image over http. Certainly on networks like 2G this task is going to take sometime, so as we know everything on android applications takes place on single main UI thread.

So doing such long task on the main UI thread will certain freeze your UI and is an example of bad user experience.

So to solve this problem you have couple of options in android, traditionally java developers will try using making a new runnable thread and executing that long task in that thread. But android application is not thread safe so its not advisable to take this approach.

So to solve this sort of problem android has a class known as AsyncTask. Using this class is quite simple.

Extend your own class from AysncTask and implement some of its required method and you are done. Lets understand the skeleton of implementing AsyncTask using some example like we will download an image on a button click and show it on an imageview.

Lets have a look at its code , this code is only for understanding your AsyncTask full code is present below:

1:   private class ImageDownloader extends AsyncTask<String, Void, Bitmap>{  
2:    @Override  
3:    protected Bitmap doInBackground(String... params) {  
4:     return downloadBitmap(params[0]);  
5:    }  
6:    @Override  
7:    protected void onPreExecute(){  
8:     Log.i("Async-Example", "onPreExecute Called");  
9:     simpleWaitDialog = ProgressDialog.show(BlogPostExamplesActivity.this, "Wait", "Downloading Image");  
10:    }  
11:    @Override  
12:    protected void onPostExecute(Bitmap result){  
13:     Log.i("Async-Example", "onPostExecute Called");  
14:     downloadedImg.setImageBitmap(result);  
15:     simpleWaitDialog.dismiss();  
16:    }  
17:    private Bitmap downloadBitmap(String url){  
18:     // code to download image for detail check the whole code below  
19:    }  
20:   }

Lets understand the code in following points:

1. As you can see you need to extend your code from AsyncTask, while extending you might have observed i have mentioned some data types, each data type has some importance, first one tells the AsyncTask about the type of data you will be passing to the class, second tells about the progress and third one tells the return type when the AsyncTask completes.

2. You need to implement at least one method of AsyncTask class and the main one is doInBackground(String... urls), in this method you need to execute your long running task, i am calling one more method which downloads the image, the parameter contains the data which can be passed from the point where AsyncTask in executed.

3. There are couple of other methods like onPreExecute which is called prior to execution and the other important one is onPostExecute which is called when doInBackground returns.

4. One this you need to keep in mind whatever data type you have mentioned which extending your class from AsyncTask, same data type is to be mentioned, e.g. the return data type we have mentioned while extending AsyncTask is Bitmap, so while calling onPostExecute we need to pass that data type as a parameter. Similarily doInBackground also needs to return a Bitmap

I hope this all clears the understanding of using AsyncTask, the next example will be about uploading an image using AsyncTask.

The complete class and the layout xml file is attached below:

BlogPostExampleActivity.java

main.xml

Let me know if you need more information about this and have any doubts on this.

PyS60 PDF documentation

2009-08-26T23:57:00.000-07:00

Hello PyS60 fans,

We all know that PyS60 team in the new PyS60 1.9.x releases have preferred a html based document over pdf document, which was the case in the earlier and stable PyS6o 1.4.x releases.

So if we observe there are many requests at the forum nokia Python discussion boards about the docs to be in Pdf, but that was not implemented yet by the Team.

No worries now one of the PyS60 aspirants Hitesh Tailor aka the86Hitman has converted the html based docs into a pdf one so that you can easily and comfortably go through that.

You can download the pdf based docs from the following links:

1.Link 1
2.Link 2

Hope you all will like that.

Cheers,

pyinfobox extension module

2009-08-17T20:22:00.000-07:00

Dear all

As clear from the title Pyinfobox is an PyS60 extension which has been developed by Thomas a.k.a treitmaier.

PyInfobox is a very simple, yet very effective extension as it displays a scrollable text dialog in a S60 device. Basically Pyinfobox is a wrapper for symbian C++ function.

Currently Pyinfobox is developed only for PyS60 1.9.x releases but back porting it to PyS60 1.4.5 will be difficult. Pyinfobox works fine with both S60 3rd edition and S60 5th edition devices.

You can know more about the Extension Module at Home Page of the Extension and if you have any problems during installation and working of the extension feel free to post your query at the forum nokia discussion boards.

All Credits to Thomas for developing such a good and simple extension.

Enjoy Pythoning

PyS60 1.9.6 is Here

2009-07-01T00:53:00.000-07:00

Hello PyS60 Fans

Its been a long time i have blogged something and here i am back some with good news. :)

PyS60 Team at Forum Nokia yesterday announced a new PyS60 version which is 1.9.6 this is again a experimental release for testing with a aim of getting an efficient final product i.e. 2.0.

Now lets list out some features of the PyS60 1.9.6 as said by tvijayan of the PyS60 Team:

Support for a virtual 4-way directional pad is added for Canvas and text widgets. This D-Pad is displayed at the bottom of the screen and this feauture is enabled by default on touch enabled devices. Currently, this is supported only in the portrait mode and landscape support will be available in a future release.
The size of the sis created using the application packager will reduce as the modules in the base runtime is more refined.

A new chapter is added in the PyS60 documentation (Extending and Embedding PyS60), that is an end-to-end tutorial for creating 3rd party extention modules and distributing them. This one is my favorite as this is a Official documentation for creating your extensions.

The above listed are the major changes from the past 1.9.5 release.

PyS60 releases can be downloaded from maemo garage where you can also file bug reports and write some feature requests.

Happy Hacking

PyS60 1.9.3 is released

2009-03-24T20:35:00.000-07:00

hi all

The PyS60 team has made it again and PyS60 1.9.3 is out. The realease is updated to core Python 2.5.4.

The following are the improvement list:

For the first time touch event support is added to the appuifw canvas. An API is added to the class, touch_enabled() checks weather the device supports touch input.
A new application scribble is developed using the PyS60 touch feature and is included in the installer.
This release includes a new extension module, sciptext. This is an enabler for using S60 Platform Service APIs that were introduced in the S60 5th Edition and back ported on S60 3rd edition FP2, from Python. It supports services like Application Manager, Calendar, Contacts, Landmarks, Location, Logging, Messaging, Media Management, Sensors and Sys Info. Refer scriptext module documentation for the usage and the convention for accessing the platform Service API interfaces is subjected to change.
SSL support has been added which has some amazing applications in future.

so with all these good improvements we all can say that the final PyS60 2.0 would be really amazing.

Enjoy Pythoning

Hi all,

On 24th of this month Forum Nokia Announced some new Forum Nokia Champions. I am very pleased to say that as usual this time also there are two FNCs from my city Bhavnagar.

The two names are my Prof. Mehul Jajal and One of my best freind Chintan Umraliya.

Mehul Sir was recently announced as the wiki contributor of december and january months. Sir has contributed a variety of articles at the forum nokia wiki on the recently announced Qt for S60.

Chintan was earlier announced as the runner up in the forum nokia wiki widget competition and was involved with me in the development of the recently announced call!nfo. Chintan is also active at forum nokia discussion boards and contributes regularly at forum nokia wiki.

Thanks to forum nokia for rewarding their activities and contribution. I am sure this will motivate some more students to learn mobile application development and actively participate in forum nokia related activities.

Best Regards

I am Back

2009-02-24T21:37:00.000-08:00

Hello all

you all must be thinking where i was all these days. Actually i was totally active on the other side but the thing was i was not getting proper time to blog all my activities. But at last today i got a bit of time and the first thing i thought was to write something here.

In the past there are lots of thing that have happened first i will talk about my favourite Python for S60. We all got a new Python for S60 1.9.x release it is unstable but have lots of benefit and the best one is the GUI based ensymble. Until now there have been two baby releases. The main aim of these baby releases is to make a very efficient Python for S60 2.0 which will be Touch UI based. You can find more about that at my Forum nokia blog.

The major achievement was the announcement of the Call logs based application Calls!nfo developed by me a my freind Chintan. Calls!nfo was completely developed in Python for S60 and is still in the Beta Version will be soon update it. More Details check here.

Another thing which i want to depict is recently me and chintan were invited to take a Workshop on Mobile Devlopment by the Computer Society of India at Vadodara( Thanks to my prof. Kiran Trivedi) The session was very short but we tried aour best to make that a very informative one.

You can read more about this on Kiran sirs Forum Nokia Blog.

Currently me and chintan are working on a very interesting project and will post the details soon. There are few more things which i want to depict but i guess its ok for now.

So stay tuned for more updates.

Best Regards

A new PyS60 version soon

2008-12-17T19:16:00.000-08:00

Hello

just in previous post i posted about the release of new version of pys60. But this post is also about a new version on PyS60.
Two days ago when i was busy in reading queries at the forum nokia python discussion boards. I came across a post by Jukka Laurila where he clearly indicated that the announcement of new version of PyS60 with Python 2.5 support is not far away. The new verion will be 1.9.x

Its really a very great news for all python developers. But for the sensor support we need to wait for the 2.0.X release.

Hope we get the announcement soon. Cant wait more for the new PyS60.

Best Regards
Gargi

"PyS60 1.4.5"

2008-12-13T10:35:00.001-08:00

hi all

After a long duration i am back with some news on my favorite programming platform i.e. PyS60.
Recently a new version of PyS60 was announced officially the version is 1.4.5.

The version contains some good points which distinguish it from the earlier version. Some good points which i liked the most are listed below:

1. Positioning Module was modified so that it can be used form several threads.
2. Timeout Support was given to the globalui module which was just announced in the pys60 1.4.4
3. Support for the "description" field has been added to the calendar module.

Though it was nice to see a new version but there were much more expectation from this version. Specially with the launch of S60 5th edition, the expectation have gone very high. There is special need for a sensor framework and touch support.

Hope we are soon going to see a one more announcement soon and i wish that with that all expectations will be fulfilled.

Best Regards
Gargi Das

hi all
One more post, this time i am writing this blog to share something about my new N810 which i got as a prize from forum nokia for the wiki quest 2008.
N810 is a internet tablet with OS2008 and the development platform is maemo. This is basically a device which is meant for internet browsing and is a wonderful multimedia device.
For internet browsing we can use any other mobile with a GPRS connection on it. The other mobile will act as a bluetooth modem for the N810. The tablet contains many good applications for internet browsing like it has a mozilla browser, inbuilt Gtalk for instant messaging there are many features and i am still exploring them.
Now some multimedia features it has a media player which supports all kind of audio formats the sound quality is really good. Same is the case with the videos very wide display and the device supports many good formats like 3gpp, mpeg4,avi.

Now something about the memory. The device has got a 150 MB of internal memory and has 2GB of external memory. But it supports 8GB expandable memory through a microSD card.

The Development platform supported is maemo thats a good news for me because i can also develop applications for it using my favorite python .

Now This is much for today i will soon edit this post to upload some photographs of the device as and when i get time.

2008-07-05T06:13:00.000-07:00

Hi to all again
Yes i am back with my blogging stuff again. I have two good and important news this time.
Lets start with the big one after the successful workshop which i conducted at my college on PyS60 i got many requests from my college friends and juniors to arrange something similar again but this time it should be in detail. So after consulting with professor Kiran Trivedi i planned to start a mobile application development group whose first and last motto will be to spread the knowledge of mobile application development through out the world.
Moreover many students dont know anything about mobile application development and forum nokia at all our aim in the group will be to make other students inform all latest about this field.
Now in the group first we have registered 10 members i will teach all of them PyS60 and we will jointly develop some good applications.
Then we all will spread our knowledge to all other students in our college as well as colleges outside. We will first start with PyS60 as it is interesting and easy to learn.
From tuesday i.e. from 8th july we will start our activities our faculty expert in the group will be Kiran R Trivedi a Forum Nokia Champion.
I will also make everybody familiar with the help and support we get at forum nokia as a developer.
The second good news is i have launched my own webpage i.e. http://mobapps.org/PyS60 on PyS60 which contains some sample codes and some articles on how to start with mobile application development using PyS60 this page will help all the new developers .
So this is enough for my first blog i will post the daily events of the group as it commences on tuesday.
