Android :: WebView / HTTPClient Shared Cookies?
May 20, 2010
An Android app I am building requires web authentication for users to make data calls. In Adobe AIR and later the iPhone, we did this by rendering a login page in a webview-equivalent page and setting a cookie when the user signs in. Subsequent data calls use the same Cookie Jar and so are seen as authenticated.
In the Android version, I authenticate the user using a WebView and then once thats done, I make a data call using DefaultHttpClient, however I cant seem to load the data on the second call.
Is there some cookie gotcha I am missing? I imagine the HTTPClient and WebView would share the same Cookie space.

I am trying to login to a site and maintain that session/cookie so that the server will recognize my login, but I am struggling to figure out a way of extracting the cookie from the response and setting into a request to maintain my login. I'm wondering if I should go about taking the header "Set-Cookie" or using a CookieStore. Any help is greatly appreciated. Here is my code that I have, with comments where I think the getHeader/getCookie methods would go.
CODE:.......
In hopes of others better understanding my confusion am adding code that I know DOES work and maintains a session but when I tried to move the code into my actual application it broke somewhere down the line.
CODE:...............
I know for a fact it works, and you can see that in this code I consumeContent() but adding that to the top code didn't seem to make a difference so I left it out.
I am still unable to get the code working in keeping a session going. I am posting the cookies from my current code, along with the cookies of the second code that is working. Perhaps someone will notice an issue, I certainly do not.
CODE:............

I have an application on appspot that works fine through regular browser, however when used through Android WebView, it cannot set and read cookies. I am not trying to get cookies "outside" this web application BTW, once the URL is visited by WebView, all processing, ids, etc. can stay there, all I need is session management inside that application. First screen also loads fine, so I know WebView + server interactivity is not broken.
I looked at WebSettings class, there was no call like setEnableCookies.
I load url like this:

Many people don't realize that they have two kinds of "cookies" on their computer. We all know about the familiar ones that web pages can place on our PC's and which we can see and delete with our browsers.But there's another more insidious kind which can be placed on your computer via Flash. These are called Flash Shared Objects, or sometimes "flash cookies" and they were disigned to provide inter-session persistency but are, in practice, used the same way cookies are. On a PC they're found in C:Documents and Settings***user***Application DataMacromediaFlash Player#SharedObjects and/or C:Documents and Settings***user***Application DataMacromediaFlash Playermacromedia.comsupportflashplayersys. They are a huge privacy violation.Browsers do not normally delete these although you can get a plugin for Firefox that does.My Question: Now that Android supports Flash, how do we get rid of these things from our Android devices?

In my Android app, each activity is filled with data from an xml file which is somewhere on the web. The website providing these files has a login mechanism, that works with cookies.
I know how to make a HTTP Request to the login page and receive a cookie. What I don't know is, how I can store it to re-use it in both other activities AND when the app is started the next time. The cookie is valid for a year, so the user of my app should log in once and then never again for a whole year.
How do I do that? I googled a lot, but either I used the wrong keywords or there are no simple solutions on the internet.

I'm developing an app that logs into a web site. To do this I use the HttpClient object.
I noticed I could get all the cookies from the post requests with the HttClient.getCookieStore method, the question is however how I save these cookies so the next time the app is started, the user don't have to log in.
I should also mention that while the login was post request, rest of the site is mostly get requests, does this effect how the cookies are managed at all?

Now, since Cookie does not implement serializeable, I can't serialize that List.

My goal is to use the DefaultHttpClient with persistent cookies.

I got the solution of get back to the first activity by pressing previous button without changing data of first activity. Now, the user will enter his credentials. When he click to proceed further, the credential details will directly go to the server and server gives response with the cookie and that cookies should be store in my phone for the usage for the future. It means that when the user again run the application he should directly logged in into the application, e.g., www.mail.yahoo.com.

I'd like to make an http request to a remote server while properly handling cookies (eg. storing cookies sent by the server, and sending those cookies when I make subsequent requests). It'd be nice to preserve any and all cookies, but really the only one I care about is the session cookie.
With java.net, it appears that the preferred way to do this is using java.net.CookieHandler (abstract base class) and java.net.CookieManager (concrete implementation). Android has java.net.CookieHandler, but it does not seem to have java.net.CookieManager.
I could code it all by hand by inspecting http headers, but it seems like there must be an easier way.
What is the proper way to make http requests on Android while preserving cookies?

I'm developing an app using android 2.1. I have a problem with using session cookies to login to a RESTful web service. The code works fine on the emulator, but when I run it on my HTC Magic, the cookie logic doesn't work. I've confirmed that the magic is receiving cookies in the headers by listing them (see attached). Can anyone say why the cookie store would be empty even tho they are in the headers?

I haven't used the Java HttpClient before and the documentation is confusing. Say I want to send a POST to the URL "https://domain/foo/ bar". I'm accessing a server with an XML API that defines the message to send like this:
code:.........
And the response to expect like this:
code:..........
Now, I can build and parse the portion inside the serverapi tags but I'm not sure how the HttpClient handles the header. If I use the standard code like this:
code:...........
In the area shown as "not sure", should I pre-pend the entire header in front of the xml section, just as it's shown in the server API document or does the client take care of the first line, since it knows the URL?
Is there a way to see exactly what is about to be sent right before I call HttpClient.execute?
As for parsing the response, I believe I can just do this:
code:..........
Or do I need to strip anything off the response content before I start parsing the xml? I took a few stabs at this and it looks like there's some HTTP bookkeeping information at the start of the response content.

I'm writing a small application which needs httpclient lib, basically to manage the cookie/session automatically. The website I'm targeting needs a valid session, so, between each http call, I need to send the cookie. Httpclient does it well. This is a tv stream application and I have to fetch the channel url, the url has a token parameter and I have to be logged / authenticated / (=> have a valid cookie/sessionid) to fetch the channel url.
I got the first cookie/sessionid with the first connection to the website. The cookie is valid for a certain amount of time, there is no "expires" but I don't know if there is any server cron to cleanup the sessions. I assume I have to "ping" every x secondes to maintain the session valid.
Between each http call, the time could be from 1 sec to several minutes, it depends if the user wants to change the watched tv channel. The http call (to fetch the url) is not made by the UI Thread.
There are several possibilities to manage the httpclient : - a single httpclient static singleton instance accessed by a custom synchronized getClient() on an helper class => when / how to release the http connection ? How to handle that correctly if the user got a phone call / does not use the application for now (unvalidate during onResume, etc)? - Save the cookie (String serialized into SharedPreferences) and create every time a new httpclient instance (then set the cookie to the new instance) => overhead to get the http connection - other ?

I had configure a Tomcat webserver with SSL and client autification. So I need a clienKey.p12 File to visit the site. If I import the key into Firefox, it works fine.
So I tried to develop a Client from "normal" Java. That works:

Now I try to develope a Client into Android and I am getting crazy....
Here my two Android implementation:
CODE:...........
I always geht the following Exception:
CODE:................
But the key is the same that I use for the "normal" java Client and for the import into firefox. So the key is valid. But it is signed by me... I don't want to sign it by a commercial Company like verisign.

I'm new to implementing HTTPS connections in Android. Essentially, I'm trying to connect to a server using the org.apache.http.client.HttpClient. I believe, at some point, I'll need to access the application's keystore in order to authorize my client with a private key. But, for the moment, I'm just trying to connect and see what happens; I keep getting an HTTP/1.1 400 Bad Request error.
I can't seem to make heads or tails of this despite many examples (none of them seem to work for me). My code looks like this (the BODY constant is XmlRPC):

For example: Say I searched something on the Walmart homepage. Like this. How would I retrieve the information from the first product listed. Information like product name, price, details, rating, model. And how would I search in the box.
The only way it seems like to me is to replace http://www.walmart.com/search/search-ng.do?
search_constraint=0&ic=48_0&search_query=someProduct&Find.x=0&Find.y=0&Find=Find.
Then replace someProduct with the seach and call it in an HttpClient.
