Question

I am building a login application in android in which i am hitting a url(with username and password) upto that part it works fine but after that whenever I am hitting a url(once the user is authenticated) , it return nothing(i.e. a error message like please login first). However it works fine in very similar iphone app and on browser.

I got somewhere that it is the error of phpSessionId(i.e. the session is destroyed for further request) and If we want our Android application to stay authenticated on the server side we need to fetch that id after the first connection and then send it in the headers of all our subsequent requests.

But the problem is that I am unable to get the sessionId from header of the first connection and sending it with further request along with the header.

Please give me some codes or links to complete the task properly.
Thanks.

Finally I solved the issue of session handling in Android.
Android cant handle the session itself(which a simple browser can) so we have to handle it explicitly.
I changed the code for http connection a bit.
Created an instance of DefaultHttpClient in the first Activity when connection established.

public static DefaultHttpClient httpClient;

For the first time connection,I did the following:

URL url=new URL(urlToHit);
LoginScreen.httpClient = new DefaultHttpClient(); //LoginScreen is the name of the current Activity

HttpPost httppost = new HttpPost(url.toString());
HttpResponse response = LoginScreen.httpClient.execute(httppost); 

xr.parse(new InputSource(url.openStream())); //SAX parsing

Now for all further connections I used the same httpClient
For example in the next activity:

URL url=new URL(urlToHit);

HttpPost httppost = new HttpPost(url.toString());
HttpResponse response = LoginScreen.httpClient.execute(httppost); 

// Log.v("response code",""+response.getStatusLine().getStatusCode());

// Get hold of the response entity
HttpEntity entity = response.getEntity();

InputStream instream = null;

if (entity != null) {
    instream = entity.getContent();
}
xr.parse(new InputSource(instream)); //SAX parsing

Hope this will help you all too to solve session issue in Android.
