Get Session from Android Webview

I have created an Android application, in that I want to get Session from webview.
How to make it possible ?
Thanks.

I use this method for getting session cookies from a webview:
public static String getCookieFromAppCookieManager(String url) throws MalformedURLException {
CookieManager cookieManager = CookieManager.getInstance();
if (cookieManager == null)
return null;
String rawCookieHeader = null;
URL parsedURL = new URL(url);
rawCookieHeader = cookieManager.getCookie(parsedURL.getHost());
if (rawCookieHeader == null)
return null;
return rawCookieHeader;
}

There are two ways:
If a developer has made a httpclient, and makes an api auth call and store the cookie. Then you sync the httpclient's cookie with webview and maintain a session natively.
If user has used a webview to make an auth call and the cookie resides in the webview.
First one is your code and simply making a getter will return instance of DefaultHTTPClient. The instance will have access to cookies too. you can make async calls to auth api to get correct cookie in the instance. Make sure to keep HttpClient and Webview in sync.
For retrieving cookie in second method, you would use CookieManager object and the url which user is logged into and you need cookie for, example twitter.com See the second post here for implementation details.

Android get session cookie from webview

I have en app with a webview to display an e-shop website.
For various reason the login par is made in a native form with a DefaultHttpClient and HttpPost.
When the user start by login, i have no problème to save the session cookie from the request to the webview cookie store.
My problem is when the user first navigate through the webview an login after, i cant retrive the webview cookie session from the cookiestore to put it to my DefaultHttpClient
this is my code :
CookieSyncManager.createInstance(context);
CookieManager cookieManager = CookieManager.getInstance();
CookieSyncManager.getInstance().sync();
cookieManager.setAcceptCookie(true);
DefaultHttpClient client = new DefaultHttpClient(clientConnectionManager, params);
String[] keyValueSets = cookieManager.getCookie(context.getString(R.string.cookie_domaine)).split(";");
for(String cookie : keyValueSets)
{
String[] keyValue = cookie.split("=");
String key = keyValue[0];
String value = "";
if(keyValue.length>1) value = keyValue[1];
BasicClientCookie2 cookieForRequest = (BasicClientCookie2) new BasicClientCookie2(key, value);
cookieForRequest.setDomain(context.getString(R.string.cookie_domaine));
cookieForRequest.setPath("/");
client.getCookieStore().addCookie(cookieForRequest);
}
In debug i see my session cookie but the getCookie method dont return it, i think it's because the cookie session domain start with a dot.
How can i maintain my webview session to a DefaultHttpClient request?

Website login and keep session cookies

I am trying to scrape some content form a website but you must be logged in order to view specific content. I want make a login using user id & password and keep session cookies on: m.amway.com i tried using Jsoup.... however after using the code below i realize that Jsoup cannot read javascript which is what the website is based on....
Does anyone have a method i could use to login, keep session cookie, and scrape content, using something other than Jsoup? Thanks in advance.
public String Jlogin(String User, String Pass) throws Exception{
String title = "didnt work";
Response logRes = Jsoup.connect(AmwayURL)
.data("userid", User)
.data("userpswd", Pass)
.method(Method.POST)
.execute();
// get all cookies
Map<String, String> cookies = logRes.cookies();
Document doc1 = logRes.parse();
String sessionId = logRes.cookie("JSESSIONID");
Document doc2 = Jsoup
.connect("https://m.amway.com/business/volume/pvbv/inquiry.ashx")
.cookie("jsessionid", sessionId).get();
System.out.println(doc2);
title = doc2.toString() + "................." + sessionId;
return title;
}

You can use a much larger API called HttpClient.
has the following classes:
- HttpGet
- HttpPost
- HttpEntity
- HttpResponse
HttpResponse reads Javascript from any page, as follows:
EntityUtils.toString(HttpResponse.getEntity());

Cookies in WebView Android

I can't read all my cookies, in my webview i can only read "PHP_AUTH_SID" named cookie, but in browser i can see all cookies. Here is my code:
super.onCreate(savedInstanceState);
CookieSyncManager.createInstance(this);
webView = (WebView) findViewById(R.id.web_login);
And this is my shouldOverrideUrlLoading() method in web view client
CookieSyncManager.getInstance().sync();
final CookieManager cookiesManager = CookieManager.getInstance();
cookiesManager.setAcceptCookie(true);
final String cookies = cookiesManager.getCookie(COOKIES_HOST);
Log.i("123123", cookies);
in LogCat i can see only: "09-13 14:05:48.139: I/123123(21188):PHP_AUTH_SID=..."
in browser:
PHP_AUTH_SID=...,
access_token=...

It seems that the output from LogCat is just cut off. Just try to debug and see the "really" content of "cookies" string.
I think you could just parse the cookies string with String[] elements = cookies.split("=")

Sharing cookies/session from WebView to HttpClient doesn't work

I know this question has been asked a hundred times, and I've read and tried for 2 hours now, but I can't find my error :-(
I am trying to create a simple webbrowser and therefore have a webview, where I login on a site and get access to a picture area. With help of a DefaultHttpClient, I want to make it possible to download pictures in the secured area.
Therefore I am trying to share the cookies from the webview and pass them on to the HttpClient, so that it is authenticated and able to download. But whatever I try and do, I always get a 403 response back...
Basically the steps are the following:
1) Enter URL, webview loads website
2) Enter login details in a form
3) Navigate to picture and long hold for context menu
4) Retrieve the image URL and pass it on to AsynTask for downloading
Here's the code of the AsyncTask with the Cookie stuff:
protected String doInBackground(String... params) {
//params[0] is the URL of the image
try
{
CookieManager cookieManager = CookieManager.getInstance();
String c = cookieManager.getCookie(new URL(params[0]).getHost());
BasicCookieStore cookieStore = new BasicCookieStore();
BasicHttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
String[] cookieParts = null;
String cookies[] = null;
cookies = c.split(";");
for(int i=0;i<cookies.length;i++)
{
cookieParts = cookies[i].split("=");
BasicClientCookie sessionCookie = new BasicClientCookie(cookieParts[0].trim(), cookieParts[1].trim());
sessionCookie.setDomain(new URL(params[0]).getHost());
cookieStore.addCookie(sessionCookie);
}
DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.setCookieStore(cookieStore);
HttpGet pageGet = new HttpGet(new URL(params[0]).toURI());
HttpResponse response = httpClient.execute(pageGet, localContext);
if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
--> NEVER Happens, always get 403
.) One of the problems is that the webview saves some cookies for the host *www.*example.com, but the image-URL to download (params[0]) is *static.*example.com. The line
cookieManager.getCookie(new URL(params[0]).getHost());
returns null, because there is no cookie for static.example.com, but only for www.example.com.
.) When I manually say cookieManager.getCookie("www.example.com"); I get some cookies back, which I add to the HttpClient cookie store:
There are 5 cookies added
- testcookie = 0
- PHPSESSID = 320947238someGibberishSessionId
- email = my#email.net
- pass = 32423te32someEncodedPassGibberish
- user = 345542
So although these cookies, a session ID and other stuff, get added to the HttpClient, it never get's through to download an image. Im totally lost... though I guess that it either has something to do with the cookies domains, or that Im still missing other cookies.
But from where the heck should I know which cookies exist in the webview, when I have to specify a specific URL to get a cookie back?? :-(
Any advice?

I guess we have made it too complicated in above snippet.
Use these easy steps -
1)Retrieve the cookie from webView -wherever your webview is, use this code to re
String cookie = CookieManager.getInstance().getCookie(
url.toString());
Log.d("mytcs", "cookie downloadlistner " + cookie);
2) Pass this in your downloading asyncTask using params -
downloadImageTask = new DownloadImage();
downloadPDFTask.execute(url, cookie);
(I assume you know to retrieve this cookie in asyncTask, you will use params[1],
3) set this cookie in your http request using -
if (cookie != null)
con.setRequestProperty("cookie", cookie);
where con is HttpURLConnection con;
so you can set it to your need, in HttpGet.

You probably figured out the answer already coz it is a pretty late answer. But, just in case...
Try this. When you retrieve the cookie from WebView just use example.com in the domain name. When you set the cookie in BasicClientCookie and set the domain, set the domain name to .example.com. Note the "." in the beginning. Now, i think the session should work across all subdomains in your application.
