Android :: HttpUrlConnection - Authentication

Mar 24, 2009

I am beating my head against a wall trying to figure out why I cannot get Authenticated on my server whilst using HttpUrlConnection. I need to post a file in a post method and it seems I cannot do so with the DefaultHttpClient and a regular HttpPost (unless I am completely missing something?). I can get DefaultHttpClient to authenticate just fine using setCredentials() but the same doesn't exist for HttpUrlConnection so I try to set through setRequestProperty: conn.setRequestProperty("Authorization", "Basic " + Base64EncodedUserNamePassword); to no avail.

Android :: Java.net.HttpURLConnection Throws - Received Authentication Challenge Is Null

Aug 31, 2009

I am using HttpURLConnection to send a GET request to a server. Upon reading the response code, the Android implementation of HttpURLConnection.doRequestInternal() throws an exception:

"java.io.IOException: Received authentication challenge is null"

I don't even get what the error is trying to tell me. I write an OAuth param string to the Authorization header, but this works fine on other occasions. There is nothing peculiar about my request apart from that.

Any idea what this means, what is causing this and how to get around it? This works fine with Sun's Java implementation, so I guess it's a problem with Apache Harmony?

Android :: HttpURLConnection And Data Roaming

Jun 15, 2010

I've got an application which is making a web request every 10s using HttpURLConnection. When the application starts in 3G, it works great. Then I activate Wifi and after that, all my requests fail during exactly 10 minutes with the fallowing exception : Socket is not connected. The behavior is the same if I start in Wifi and then I switch to 3G. What's the problem here ? Do we need to setup something at socket level ? a timeout (10 minutes is the default one) ?

Android :: HttpURLConnection Returns Corrupt Data On Dev Phone

Feb 17, 2009

This is an issue that has kept me from doing real work for *a while* now:

The Task: Read an image from the net (PNG approx. 10kb) and writeit to the user dir as is.

I'm using a byte array to temporarely store the data, basically like this:

CODE:..............

The Problem: it works - sometimes. Actually it always works in the emulator, and it usually works when attaching the debugger to the phone and stepping through the code. Interestingly it almost always produces corrupt images when running in 'normal mode' - read on the Dev1 via UMTS.

Corrupt images are good at the start of the image, and somewhere in the middle or to the end, they produce pixel trash. They can't be decoded to a Bitmap or alike as well.

I'm almost sure it's a HttpURLConnection issue, or at least related to it.

BTW. the download happens in it's own object instance, but about 10 are triggered in a loop after each other.

Android :: HttpURLConnection Doesn't Send Correct User-Agent Header

Sep 15, 2009

I have a server that uses User Agent header to identify the device that is connecting to it. But when i connect to the server using HttpURLConnection i get no User Agent header, but when i connect with the browser it sends the correct User Agent.

For testing i am using an echo server that replies with the headers it found on the request.

When i connect with browser i get: eg: User-Agent: Mozilla/5.0 (Linux; U; Android 1.5; en-fr; HTC Hero Build/CUPCAKE) AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/525.20.1 Up.Link/6.3.1.20.06.3.1.20.0.

But when i connect by code with UrlConnection i get: User-Agent: UNAVAILABLE.

Does anyone know we i get different behaviors? How i can i connect in the same way the browser does?

What i really need is not only the User-Agent header, i also need some special headers (x-up-subno actually). This header is added by the APN of the operator, but for some reason when i connect by code that headers are not added to the request.

From browser:

Android :: SSL Client Authentication

Android :: Writing Authentication System

Jul 21, 2010

I am currently writing the backend for a service which has 3 clients: browser, android native and iphone native. I am having a little trouble with coming up with an authentication system since I don't know what can really be done on the clients.

I am using django + twisted for the backend.

Basically, I am going to be writing RestfulAPIs to open up for the clients on both phones to call.

Now the real question is, how should I come up with an authentication system?

I have thought about using sessionids, this works very well with the browser and I can use django's integrated app for that.

However, I don't know if it's possible for both the iphone and android to obtain a unique sessionid on the handset. Should I write an API call to distribute unique sessionids?

if that's the case, is it possible for me to still use django's authentication system since a lot of the stuff here are customized? ( I am not even using a rdbms - I am sticking with mongodb, so I was on the verge of dropping django's authentication app ftm).

I have looked at foursquare's API and their basic auth method requires you to pass in user:password in every http request header. That adds 1 additional authentication each call which can kind of seem excessive.

Android :: Podcast Application That Allow Authentication?

Oct 20, 2010

Are there any podcast players that allow authentication? I have the streamlink account for coast to coast am and they dont yet have an android app. I can download the MP# files of the shows every night but would much rather be able to just stream with podcast. I have a link to the RSS feed for said podcast but it requires a UN/PW. Can anyone suggest an app that will handle this? They also provide Real Player links and Windows media player links so if anyone knows how to make these work with the droid that would work as well.

Android :: How Should Web App Use Facebook Connect Authentication?

Aug 8, 2010

My website uses Facebook Connect for authentication on the desktop and mobile sites. When a user clicks the Facebook button, the browser opens a popup window where the user can login to Facebook. When the user logs in, the window closes and messages the main window to go on.This works great on iPhone. A new window opens and is brought to the foreground. After logging in, brings the original window to the foreground. Everything is happy.On Android, the user experience sucks. Trying to be clever, Android opens a popup window on top of the current window. However, the login popup is completely zoomed out and the input boxes are tiny. Predictably, many users just close the popup and give up.How can I use the Connect JS library to force a real window to open, or at least force Android to make the login box presentable?

Android :: Server Certificates For Two Way Authentication SSL Socket

Oct 31, 2010

I'm working on an Android app that requires both client and server certificate authentication. I have an SSLClient class that I created that works beautifully on regular desktop Java SE 6. I've moved it into my Android project and I'm getting the following error: "KeyStore JKS implementation not found".I've looked online a bit and it looks like there's a possibility that Java Keystores are not supported on Android (awesome!) but I have a feeling there's more to it than that because none of the sample code I've found resembles what I'm trying to do at all. Everything I found talks about using an http client rather than raw SSL sockets. I need SSL sockets for this application.

Android :: Basic Authentication Post Cupcake?

Android :: HTTPS Authentication Over WiFi Using HttpClient 4

Jul 9, 2009

I have Android pet-project DroidIn which utilizes HttpClient 4 (built into Android) to do some form based authentication. I started noticing that people who are using WiFi are reporting connection problems. It also doesn't help that site I'm accessing has self-assigned certificate. Well - the question is (I'm quite vague on WiFi details) If WiFi at the hotspot doesn't support HTTPS would that be a good enough reason for connection to fail and is there anything that I can do beside proxying into another appserver using HTTP which then would call HTTPS site?

Android :: Apache HttpClient Digest Authentication?

Basically what I need to do is to perform digest authentication. First thing I tried is the official example available here.

But when I try to execute it(with some small changes, Post instead of the the Get method) I get a

CODE:..................

When this failed I tried using:

CODE:.................

At first I have only overridden "realm" and "nonce" DigestScheme parameters. But it turned out that PHP script running on the server requires all other params, but no matter if I specify them or not DigestScheme doesn't generate them in the Authorization RequestPreperty when I call its authenticate() method. And PHP script returns HTTP response code 200 with a message that PHP script requires cnonce, nc and qop parameters.

Android :: Activity Flow During OAUTH Authentication

Feb 3, 2010

I think that I've found the problem I am having with AccountManager that I described in an earlier thread that got no responses on the board.

I think it is a problem with the way that the Activity Stack is working during the OAUTH workflow. Here's the workflow as I see it. I found this problem by separating out my Activity, which I'll call M, from the oauth Activity, which I'll call O. In the course of authentication, the web browser is invoked and let's call that B.

When a user needs to start over with authentication, my application, through Activity M, starts Activity O. That, in turn, generates some magic URL that is sent to the web browser. So the browser is fired up and information was sent to the OAUTH provider to do a redirect back through the browser back to Activity O.

So, this how the OAUTH workflow looks up to the browser: M -> O -> B

At this point the user logs in and hits the Accept button and the browser then invokes my BROWSABLE activity, which, again, is O. I had thought this would unwind the above stack, but it seems that above situation disappears and what I have after the user hits Accept in the browser is this: B -> O

What I did to work around that is that I put a startActity(M) in O and that seems to work, but it is a workaround.

I believe there is something that I could do with launch modes or activity modes to fix this problem and maintain the original activity stack.

All that is happening, really, is that the O activity pauses for little while, then comes back with the goods, the login credentials. But when I tried to return the information via startActivityForResult (), nothing. Because M is no longer on the Activity Stack.

Android :: Issues With Httppost - Authentication Challenge Is Empty

Nov 3, 2010

I'm developing an Android app which needs to perform an HTTPPost to get a token back. Then use that token for subsequent calls. When I perform the initial call to get the token, it throws an exception: org.apache.http.auth.MalformedChallengeException: Authentication challenge is empty

Here is my code:...............

I googled "Authentication challenge is empty", and one this website: http://fmpwizard-scala.posterous.com/using-apache-httpclient-authenti... he had a similar problem. He determined that his web server requires preemptive authentication. Which I believe ours does too. I tried implementing what he did, and still, no dice.

I've hard coded the token in other requests, and I am able to perform HTTPGet calls.

What is the Authentication Challenge that I'm missing?

Android :: Send Email (Username And Password Authentication)

Nov 21, 2010

I am trying to send an email to a specific address by using my own email. So far, I know that I can use android.content.Intent.ACTION_SEND to send an email. For instance:

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text"); emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"blabla@gmail.com"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Log-in Sucessful");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Hi");
Activity context = null; context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));

However, I do not know whether ACTION_SEND can accept username and password as well. This username and password basically will be used to authenticate the email sender. It's just like when you need to log-in into your gmail account before you can compose and send an email to someone.

Android : Access Basic Authentication To View A Protected Url

Apr 6, 2010

I'm trying to do basic authentication to view a protected url. I want to access the protected url which looks like this:

http://api.test.com/userinfo/vid?=1234. So I do the following with a WebView:

mWebView.setHttpAuthUsernamePassword("api.test.com", "", "me@test.com", "my password");
mWebView.loadUrl("http://api.test.com/userinfo/user?uid=53461");

but the authentication doesn't seem to work, I'm just getting an output error page. Am I using the WebView method correctly here?

Update:
Trying with curl: curl -u me@test.com:mypassword http://api.test.com/userinfo/user?uid=53461

and it pulls the page fine. I tried every combination of the host parameter, the owners of the api don't know what I mean by 'realm' though (and neither do I) - what info could I give them to help this along?
