How can I call a Webservice with a byte[] parameter? Tried using the namedvaluepairs, but they take strings only. I am not using the Ksoap2, we decided to use the HttpClient / HttpPost method.
Here is my code:

I am dealing with http post method on Android. I have successfully send simple string pairs using HttpClient and HttpPost class with the NameValuePair as entity. However now I want to send a simple array of bytes[]. Unfortunately the only entities I have found for the HttpPost class are the NameValuePair and FileEntity. However my byte[] is not from a file. Wirting it to a file and then sending by the FileEntity seems to be pointless and stupid. How can I send this array using default HttpClient and HttpPost class?

Now, I have this working with what is no longer supported in MultipartEntity as follows:

Problem is MultipartEntity is apparently no longer supported, although I found the libraries I can include in my project.
I'm passing in parameters and returning string values, but all I receive is: org.apache.http.conn.EofSensorInputStream. Do I need to do something special in my web service to access the parameters being passed?

I would like to create a Java-written RESTFul Web Service, possibly using an eclipse plugin.
This service should be consumed by an android application, using the apache HttpClient.
But my question is, which is the best/ideal technology (server side) to implement this kind of web service?
I'm using eclipse to develop over android, i'm trying to connect to a .net webservice...when i'm calling a webmethod with no parameters it works fine... but when i come to pass a parameter to the webmethod things turn upside down... the parameter is passed as null (while debugging the webservice i discovered that) and i get a null from the webmethod in the client side code... i've been searching for a solution for a day now and all that i can interpreter is that people keep talking about encoding styles and such stuff.... i've tried it all but in vain. i'm using ksoap2 version 2.3 with the following code:
CODE:......................
I got one blog which interacts with servlets... Link as follows
http://groups.google.com/group/android-developers/browse_thread/threa...
In that program 2 libraries were used..
1---> import org.apache.commons.httpclient.HttpClient; 2---> import org.apache.commons.httpclient.methods.GetMethod;
When i check these libraries in my program, its show error....how to resolve this error?

CODE:.....................
The reponse returns "HTTP/1.1 200 OK" so it does find the file
I tried removing the file and it returned Error 404
I read apache's docs and looks like am doing it right "i think"
My problem is... the contents of the file do not get updated!

I am looking for an example of using a WebViewClient with shouldOverrideUrlLoading and using HttpPost. I need to display a web page, keep it within my layout boundaries so it can not launch a new browser and also use HttpPost to send data to the host.

I have a hello.php running on standard Linux host. (Ubuntu 9.01 with Apache2 web server)
In android I have a simple activity which sends HttpPost or HttpGet to the above hello.php with some parameters in URL. Irrespective of HttpPost or HttpGet in my php always $_GET has values, $_POST is always empty.
How do I know in PHP if it was a post , get,put or a delete? $_REQUEST['REQUEST_METHOD'] is also always empty in my php.
I want to attach a file as HTTPResponse on Android 1.5. Also the contents of the file needs to be assigned to some variable.
View 2 Replies View RelatedI'm creating an activity which needs to upload an image to a webservice using their api. I found that if i use UrlEncodedFormEntity and send the image data through that. the webservice doesn't receive that. ( at least it will not be able to read that .) In fact if i add some vars to send with the image data ( like name of the file, filesize ) they can be read from the webservice but the image data still doesn't appear if i try to read it serverside.
View 1 Replies View RelatedI'm trying to use HttpPost to send data from an android device to a server. It works great with a Wifi connection, but I get the IOException "The target server failed to respond" with a Mobile connection (3G, Edge, etc.). It doesn't seem to be a timeout problem (I set it to 90s). The use of HttpGet works perfectly with both Wifi and Mobile connection... Any idea of where the problem could come from?
View 5 Replies View RelatedI've written some code for my Android device to login to a web site over https and parse some data out of the resulting pages. An HttpGet happens first to get some info needed for login, then an HttpPost to do the actual login process. The code below works great in a Java project within Eclipse which has the following Jar files on the build path: httpcore-4.1-beta2.jar, httpclient-4.1-alpha2.jar, httpmime-4.1-alpha2.jar, commons-logging-1.1.1.jar.
public static MyBean gatherData(String username, String password) {
MyBean myBean = new MyBean();
try {
HttpResponse response = doHttpGet(URL_PAGE_LOGIN, null, null);
System.out.println("Got login page");
String content = EntityUtils.toString(response.getEntity());
String token = ContentParser.getToken(content);
String cookie = getCookie(response);.......................
I'm on Android 1.5, and my code is like this:
CODE:....................
After successfully executed these codes, the result is a stripped string. I've tried using browser to test the url+param, it works fine and got all data.
What's wrong with this code? Is there any parameters I need to specified?
I want to use HttpPost over https/ssl. I get 'Not trusted server certificate' error. I've found a lot of posts, seems that many people have similar problems and I've found two suggestions: 1) Change server's certificate. Current certificate is self-signed as localhost.localdomain. Unfortunetly it's not my server and I cannot change the certificate. 2) Use HttpsUrlConnection instead of HttpClient. But I cannot use it because sometimes (when response's code is 401 or 403) I got IOException during getting response code or reading inputstream.
So I've found 3rd solution - use httpclient, when system throws excetpion 'not trusted server certificate' than display warning, inform user that certificate is not trusted and ask if he wants to add this one to the keystore (webbrowser works this way). But I've no idea how to get certificate from the server and add to keystore.
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?
I have an image sitting on my SDcard (of type jpg) and I am trying to send the image via HttpPost to my servlet running on Apache Tomcat 7.0 So far I have google-ing the way to do this but I can't seem to find the perfect way. Do any of you might have some suggestion or solution to this problem?

View 3 Replies View RelatedI am currently sending and receiving SIP messages across a network. When I want to add SDP data to a SIP message I use the SessionDescription object in jrtp. This object is then added to the SIP message. But when I get a SIP message from the server its SDP is in a byte[] array. So I'm wondering is there anyway to convert the byte[] back into a SessionDescription object so I can use the SessionDescription object's methods to parse the data?
