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.

Android :: Need Download Link For Httpclient Multipart

Jun 9, 2009

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.

Android :: Android JSON HttpClient To Send Data To PHP Server With HttpResponse

Mar 29, 2010

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";................

Android :: Download Multiple Objects From Same Server

May 5, 2010

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.

Android :: Market Server Bug - Download Error

Sep 4, 2010

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 ....

Android :: Using HttpClient

Aug 24, 2010

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.

Android :: Best Httpclient Re-use Stategy

Jun 21, 2010

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 ?

Connecting MySQL By HTTPClient Via PHP?

I'm trying to create a login function in my new App.I wrote a php file in my server to be an interface between my App and MySQL.

Quote:

private void connectPHP(){
try {
HttpClient client = new DefaultHttpClient();[code].....

I expect responseMessage will equal to "Success", but as result it returns a NULL value.

1. I'd try the php file in a web browser and it operates normally, I'm sure the problem came from the JAVA code.

2. I'd try to use the response.getStatusLine().getStatusCode() method to check the HTTP status code, but it doesn't return any number.

Android :: Httpclient And Selfsigned Certificates

Jun 25, 2010

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.

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.

Android :: Httpclient Redirect Handler

I'm trying to call a web server that is using relative URL redirects for some of the calls. This of course isn't working with DefaultHttpClient as it isn't treating it as a relative URL. I've gotten as far as implementing a RedirectHandler in an attempt to catch the redirect and add in the base call but I can't work out how to get the location of the redirect.

With the following method how do I go about finding out where I am being redirected to? I can't find any fields on either response or context that have what I need and I don't know where else to look.

Android :: One Vs Many Instances Of HttpClient Per Application

Oct 23, 2009

Until recently, our app shared a single Apache HttpClient instance using the ThreadSafeClientConnManager across the whole application. The http client instance was held by a singleton class.

Since I dislike the singleton pattern for its numerous problems, I refactored our API accessor to be a per-thread object, but now for every thread (which mostly means per Activity/Service in our case) a new HttpClient instance is created.

It's not that I have problems with this new approach, but I've read that the Apache folks suggest to only have one instance per app for performance reasons.

Visually, what we did before was this:

HttpClient (thread safe)
|
|
/
/
Activity1...ActivityN

Now, we do this:

Activity1 ... ActivityN
| |
| |
HttpClient1 HttpClientN

How do you guys do this in your applications? If you share one single HttpClient across your app and potentially many concurrent threads, how do you handle access to it?

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.
