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

I am trying to send requests to a server in JSON format but my app die on the emulator when i try to send request. However the same code works fine as a normal java application.
Here is my code:
Code:
private HttpResponse doRequest(String url,JSONObject jso){
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost(url);
HttpResponse response = null;
[Code]...
What wrong with this code if it run perfectly in a java application?

I am working on my first Android Application. Now wat I want to do is to make a POST request to a restfull service running on server and I want the BODY of this request to be a JSon String. I am using GSon to generate the JSon to send to server. The code I am using to make the POST request follows:
HttpPost requisicao = new HttpPost();
requisicao.setURI(new URI(uri));
requisicao.setHeader("User-Agent", sUserAgent);
requisicao.setHeader("Content-type", "application/json");
HttpResponse resposta = null;.................

I know that this is not really an android question but i am new to both android and JSON. "Email":"g...@tkxel.com","Password":"123456"} to a url. The above structure is sent to Server in a variable named "json". The server reads the data and sends back the user information in a json object if the login is successful or {"error","-1"} if the authentication fails.................

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.

I am developing an Android app that needs to communicate bi-directionally with a server. By that, I mean either the server or the device can send a message at any time, with an arbitrary amount of time in between messages. Sending data from the device to the server is a common and I think well understood task, but I'm not as sure what the best approach is to go in the opposite direction from the server to the device.
I think having the device periodically poll the server may be a bad idea due to latency and the drain on the battery, but I'd be willing to consider this option. My plan at the moment is to send text messages from the server via an email-to-SMS bridge, and to have my app run a service to receive and handle these messages.
The question I have is if there are any best practices for this scenario, and if using text messages has some downsides that I have failed to consider. For the sake of this question, I want to assume that users have an unlimited text data plan, so paying per text won't be an issue.

How I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results.
What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content).
This is what my code looks like simpliefied with the most important parts (I think).

I'm building an android app which should perform a GET on my site to get two cookies and then perform a post to the same site with these cookies.
As mentioned I start of with the GET and I'm using org.apache.http.client.HttpClient to perform this operation.
CODE:..............
So far so good. Don't mind the requiredCookies line yet, it will be used in the Java.net impl since I can't get the HttpClient one to work =(.
Let's take a look at the non working HttpClient Post part.
CODE:............
What happens now is that I perform a POST with the localContext where the cookies are stored. This doesn't work. I get a HTTP/1.1 401 No session. Since I had no luck with this I tried another approach(java.net.HttpURLConnection). Remember I still use the same GET part
CODE:.............
And VIOLA a 200 is displayed and everything works like a charm.
