Android :: Sending Multiple Http Requests To Django

May 19, 2010

I am developing a microblogging platform in which I need to populate the page with Post (user defined class with fields) obtained from the Django server using HttpGet.In the client side(Android) I am using GSON to parse the responses from server to the type Post. So I require that server should send Post's one by one so as to add each of them to a list of Posts after parsing and then finally notifying the list adapter of changes in the data set after all Post's have been added.But the problem coming when intially loading the application, the page has to be populated with 10 latest Post's from the server. So I thought of a rather dirty way of sending 10 httpget requests to the server one after the other to the server. The code looks like this.I was thinking of executing it 10 times in a loop to get the 10 Post's I require. But in Django as far I know (correct me if I am wrong) there's no way to keep an index of the last sent Post to the client and so no way to send the 'next' Post on the next HttpGet request. So I am out of ideas.I feel there's a better way to do this efficiently.

Sending And Receiving Asynchronous HTTP Requests?

Jul 20, 2012

I developed a game for Android called Jumping Bird, it writes the score obtained by the player in the database on my web server, but it does so synchronized. While it tries to write data in the database on the web, the entire game is stopped , and worse, when the server is slow, the request takes more than 5 or 10 seconds, an ANR(application not respond) error occurs and the OS tries to close the app.

I wonder how I can make that request asynchronous.There is any library that does it?

Android :: Simultaneous Http Requests

Jan 13, 2010

Is there a limit on the number of simultaneous http requests of the form:

HttpResponse response = client.execute(request);

I'm interested in any official limit as well as practical ones.

(In a previous life, you had to dig deep to discover that WinMo only allowed three WebRequests to be open at a time.)

Let's say I have a list of 20 files to download on a background thread.

Should I: Download them one at a time, blocking the thread (but not the UI thread) to wait for each one? Start 20 threads each downloading one of the files?

I expect the answer may be somewhere in between, where I create C threads and work on the queue of N files, where C is a number like 3 or 4.

I suspect some of you here have already done some experimentation and know the magic number. In addition, I suspect there may be more efficient ways of doing what I'm doing than creating a new DefaultHttpClient for each request.

Android :: How To Do Async HTTP Requests?

Feb 23, 2010

Im using a web service, so I want to use an async thread for the HTTP authentication request and another thread later to make additional service requests while my main thread runs.Would like to see a good example of how to do this and how to show busy messages somehow in main app. How does the main app know when the thread finished? And what if my thread encounters exceptions, how do I deal with that?HTTP requests are sent later, use the same cookies setup up by the first auth request, so will the later requests pick up the same cookies and just work?

Android :: Multi Threaded Http Requests Cause Exception

Jan 27, 2010

I have an app making an https post on one thread while performing a file download on another thread. For some odd reason, I am getting a ClientProtocolException saying that "The server failed to respond with a valid HTTP response". The error goes away if everything is run on a separate thread. Oddly if I run the two server requests in serial, the error goes away. It seems there's a bug that happens when two requests are made at the same time.

Important note: The post occurs to a different server than the download so the servers themselves should not be causing the problem. The code is simple. Here's the file download code:.............

Android :: How To Use Separate Thread To Perform Http Requests?

Aug 2, 2010

I have an application that is performing HTTP Requests (specifically calling the FogBugz API) when the user clicks certain buttons. Right now, I am just creating a service when the application starts, and then calling different methods in that service to complete requests. However, when I do this, there is the usual hang in the UI thread. I have looked at AsyncTask, but am not sure it will do what I want to accomplish. Because I need to instantly parse the XML that the HTTP Request returns, I need to have a process that is able to return this data to the UI thread. Will ASyncTask be able to accomplish this, or is there some other way.

Android :: Injecting HTTP Header Into All Requests By Emulator

Mar 17, 2009

Is there an easy way to inject a header into all HTTP request sent from the emulator, including HTTP requests made by my app and also by the built-in web browser? I need this ability to model the behavior of a carrier gateway. I tried running the emulator through Fiddler as a proxy because I know how to manipulate HTTP requests in Fiddler, but that that didn't work. The emulator was successfully able to make the first HTTP request, but choked on subsequent ones. Reading this list, it seems that getting the emulator to use a proxy is not is not that easy. If this is the only way to do what I need, then I'll certainly give it another shot and post details about any problems I encounter. I am just wondering if perhaps there is an easier way to inject a header.

Android :: Android Platform - Efficiently Sending Protocol Buffer Messages With Http

Mar 16, 2010

I'm trying to send messages generated by Google Protocol Buffer code via a simple HTTP scheme to a server. What I have currently have implemented is here (forgive the obvious incompletion):
HttpClient client = new DefaultHttpClient();
String url = "";
HttpPost postRequest = new HttpPost(url);
String proto =;
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("sdroidmsg", proto));
postRequest.setEntity(new UrlEncodedFormEntity(nameValuePairs)); try { ResponseHandler<String> responseHandler = new BasicResponseHandler(); String responseBody = client.execute(postRequest, responseHandler);} catch (Throwable t) { }I'm not that experienced with communications over the internet and no more so with HTTP - while I do understand the basics... So my question, before I blindly develop the rest of the application around this, is whether or not this is particularly efficient? I ideally would like to keep messages small and I assume toString() adds some unnecessary formatting.

Android :: How To Parse Responses From A Django Server In Droid

May 8, 2010

In the Android application I am building, I want to be able to communicate with a local server developed in Django. (Basically a login page and a home page populated with posts and images from users) So do I need to use XML Parsers for the parsing the response from a Django server or is it possible for the server to respond with strings which can be directly used? Also what about images?

Is the JSON or XML Parser easier and robust to use in Android? The responses would be basically like tweets with a username, image and message. I was thinking of using the SAXParser. Any better alternatives?

General :: Sending MMS To Multiple Friends?

May 23, 2012

I'm using Go SMS as my default message app on my Droid 2. When I send a picture to more than one contact, everyone I sent it to gets any response any one does to the message. This is obviously not cool.

I can't find an option to turn that off, I'd never even heard of such a feature before. Not sure if that is an Android thing or just my app. I want to continue using this app but I'm not going to send a picture to umpteen different people 1 at a time.

Motorola Droid :: Sending Pics To Multiple Recipients

Jan 3, 2010

I spent a while searching for the answer but had no luck...

When I take a pic that I want to share, I'll tap "Share".

There, I will access the field to enter an email address that I want to send the photo to. If I have multiple people to send it to, do I have to type in each individual address, or is there a way to access my contact list somewhere so I can simply go through and select/click recipients?

General :: Sending A Single Message To Multiple Recipients?

Dec 18, 2011

Is there a way for sending a single message to multiple recipients for the message to be placed inside the conversation for each individual instead of creating a new thread for that one message?

I downloaded the Handcent App and even it does the same thing as the stock app. It appears there's an option to split the message up as described when sent to a group. But it still creates the new thread whenever sending to individual names.

HTC Desire :: Handcent Not Sending Text Messages To Multiple Contacts

Jul 9, 2010

I've been using Handcent since I've had my Desire, but since the last few updates it seems to have developed a fault when sending the same sms message to multiple contacts. If I send a message to say 3 people, it either force closes, or comes up with the error message not sent. If it comes up with the latter, the messages are queued & sent 1 after the other. I was able to do this no problem before, so has anyone else experienced this in Handcent?

Android :: Viewing Requests Made By Another App

Sep 16, 2009

Is it possible to view what requests are made to external sites/ servers by an app? Basically I'd kind of like to throw an application (I did not make) into a debugging type thing to see what requests (to where and what data) it makes. This is to kind of ensure a third party app does what it is saying, and isn't sending data elsewhere.

Android :: How AJAX Requests Work On 2.0 / 2.2 Emulators?

Jul 22, 2010

I'm testing out a web page on the Android 2.0 and 2.2 emulators, and the jQuery.ajax() requests that the app makes have slightly different behaviors regarding HTTP Authentication Headers. The server I'm making requests to requires basic authentication, and the ajax requests in 2.2 send the proper auth header. In 2.0, I am debugging with Fiddler, and it seems that the requests do not include the auth header, and the server rejects the request with a 401.2 error. I don't think it matters, but the server is running IIS 7. One interesting thing I noticed while debugging the web requests is that Android 2.2 makes two requests for each resource, whether or not it's an XHR. One does not contain the Auth header, and the second one does. In 2.0, it seems to make 2 requests for everything but XHR's:

Here is the 2.2 header for the first XHR:
Accept-Encoding: gzip
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; sdk Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
Accept: text/plain, */*
X-Requested-With: XMLHttpRequest
Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7

The 2.2 header for the second XHR:
Accept-Encoding: gzip
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; sdk Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
Authorization: Basic cGFyaXZlZGFcZGF2aWQubW9ycmlzOjIzbkx2ZWxsbGw=
Accept: text/plain, */*
X-Requested-With: XMLHttpRequest
Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7

And the 2.0 header:
Accept-Encoding: gzip
Accept-Language: en-US
User-Agent: Mozilla/5.0 (Linux; U; Android 2.0; en-us; sdk Build/ECLAIR) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17
Accept: text/plain, */*
X-Requested-With: XMLHttpRequest
Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7

Has anyone experienced this behavior before? It is basically causing my app to not work at all in version 2.0. Version 2.1 seems to act the same as 2.0.
