Android :: Can't Download With HttpClient With A Different Server Port
Aug 18, 2010
I am using Apache's HttpClient via httpclient-fluent-builder to download a http page.
This is the code:
CODE:..............
Problem is that I get org.apache.http.client.ClientProtocolException
It's something with the host:port/url, beacause it works with urls without ports. I also get this same error with another Httphelper class than fluent-builder. Firewall is off.

HttpClient 4 doesn't have that included anymore. The upstream project didn't integrate it from the 3.x client. I had to do exactly the same today. Basically I solved it by including some additional jars: mime4j httpmime This question was already on the list and there's some better explanation: http://groups.google.com/group/android-developers/msg/1ea124b384da9dc2 -- Urs My problem is that while i know what i have to include, i can't find a sensible download link for httpmime. the page points back to httpcore for downloads, but of course it's not in there any more (i checked). i was up for compiling it, but the source link takes me to the javadoc! something is definitely screwed up.

I am currently trying to send some data from and Android application to a php server (both are controlled by me). There is alot of data collected on a form in the app, this is written to the database. This all works.
In my main code, firstly I create a JSONObject (I have cut it down here for this example):
JSONObject j = new JSONObject();
j.put("engineer", "me");
j.put("date", "today");
j.put("fuel", "full");
j.put("car", "mine");
j.put("distance", "miles");
Next I pass the object over for sending, and receive the response:
String url = "http://www.server.com/thisfile.php";................

Socket client = server.accept();
} catch (Exception e) {
// TODO Auto-generated catch block a = false;
e.printStackTrace();

How can I utilize Connection: Keep-Alive option, re-use connection and download multiple objects from the same server? HTTP connection consists of opening a socket, sending request and then readign response. For Keep-Alive option open the socket connection needs to be done only once. However I could not find in Android Java classes how this can be accomplished. URL.openConnection returns new instance of HttpURLConnection implementation for every request so HttpURLConnection cannot be cashed for reusing on multiple requests to the same server, URL object is also new for each request and also cannot be reused.

I found a problem with the Market yesterday:
Upload a new APK version 134 After the upload finishes, cancels the upload Upload a new APK (different than the last uploaded file, but still version 134) Publish
10 minutes later I found my app was missing from the Market. I went to Developer Console and it asked me to agree to new license agreements, so I did. At this point, my app's status is again visible from the Market. I felt satisfied and went to sleep.
Next morning I got a flood of e-mails saying that my app shows "Download Error" in Market, and no one is able to install or update. I tried myself and say "404" error in logcat. Apparently the APK has been lost by Google server.
I uploaded a new version (just rebuilt and bumped version to 135), and I verified that the app can be downloaded again.
I guess the moral of this story is to always verify that you app can be downloaded after uploading ....

Is it required to install anything at my server? which I cannot do because of the shared account. Any way to just open the connection, update some data in the MySQL from j2me application?

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:

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.

I am using httpclient for my android app and I have a local site which has a few https pages. Since default httpclient doesnot allow self-signed certificates I am using "EasySSLFactory" and "EasyX509TrustManager", which are mentioned in httpclient documentation.
CODE:.......
The problem is if I use this SSLFactory in my android app, I am getting correct response from my site's https pages, but I get "SSL handshake failure: I/O error during system call, Unknown error: 0" for sites such as "gmail.com", "ymail.com". If I don't use. "EasySSLSocketFactory" I get response from these sites but get exception for my site.
This page fetch code works fine as a standalone java application.

I'm connecting to a REST service using HttpClient under Android. I'd like to be able to write code where I could pull the host, port, etc. out of a properties file and not have to write fake Schemes and other things like that in order to do the development work. In other words, the live site will have a cert. The dev site will have a self-signed cert or a CA cert. Either way, I need the code to seamlessly work with both kinds of certs if possible. Can someone point me in the right direction?

I am having a hugely annoying issue with delays using HTTPClient and post the first time I call execute on the client the response takes 5 seconds to come back. Subsequent calls take around 100 to 200 ms. I am using the Apache client so does anyone know why this takes so long? The client setup looks like below

The timing for this look like below.
