This is the servlet code in java ME.
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
ArrayList<String> listName = new ArrayList<String>();
ArrayList<Integer> listLongitude = new ArrayList<Integer>();
ArrayList<Integer> listLatitude = new ArrayList<Integer>();
String sLongitude = (String) request.getParameter("x");
String sLatitude = (String) request.getParameter("y");
String path, list, scount; Integer numLong = null;
Integer numLati = null; Connection con = null; String slanje = "";
int limitLeft, limitRight, limitUp, limitDown, icount = 0;
if (sLongitude != null && sLatitude != null) {
try { numLong = Integer.valueOf(sLongitude);
numLati = Integer.valueOf(sLatitude); } catch(Exception ex) {}
} try{ Class.forName("org.apache.derby.jdbc.ClientDriver");
con = DriverManager.getConnection("jdbc:derby://localhost:1527/bazaprojekt", "projekt2009", "midlet"); limitLeft = numLong - 8; limitRight = numLong + 8; limitUp = numLati + 8; ...
How do I send x and y to servlet and receive some string in Android?
I'm writing an Android application. One problem is your app cannot contain a file whose uncompressed size is bigger than about 1Mb. I have a serialized object that I want to load that totals about 2Mb. My plan was to split this file into two smaller files, then load the object by combining both files at runtime.
However, I cannot work out how to use e.g. InputStream and ObjectInputStream to specify that I want to read the data from two input streams. How can I do this?
For example, say my object was split between file O1 and O2. How can I say "Load the object by reading the data from O1 then from O2"?
An application currently I am developing needs data fetched from a database by a servlet. I have no clue how to invoke the servlet from my client. Any inputs are greatly appreciated. I am an absolute beginner.

View 3 Replies View Relatedi'm sending an http request to the google reader api and getting an unusual response code. following the documentation, i've requested an auth code and included it in the header of every request. after performing the login, and getting an auth code, i tried accessing this url, which is part of the documentation: http://www.google.com/reader/api/0/stream/items/contents when i send the request, i get a 411 status code, which is supposed to mean "Length Required". the length, as i've found, is supposed to be the length, in octets, of the message body. there is no message body in this request. there is only a single header, the POST parameter i="item id" and the URL itself. i tried setting the "Content-Length" header to "0" and also to "-1" to no avail. what's really interesting is that this same code worked fine before google changed their authorization procedure. it's apparent they've changed something else. so my question is what EXACTLY would cause a 411 response code and how can i prevent it?
View 1 Replies View RelatedI have a Service for my Android app that performs HTTP calls. The Service stores cookies in a CookieStore. I am trying to find a way to persist the CookieStore but I haven't been successful. I don't want the user to log in every time to receive a new CookieStore.
I tried to use SharedPreferences to store the CookieStore as a string, but I can't re-construct the CookieStore with a String.
Has anyone else had success in persisting a CookieStore?

Does anybody know what version of Apache HTTP Client this is supposed to be? I want to run it without the Android tests which are painfully slow.
I'm doing a Get and Post method for an android project and I need to "translate" HttpClient 3.x to HttpClient 4.x (using by android).
My problem is that I'm not sure of what I have done and I don't find the "translation" of some methods...
This is the HttpClient 3.x I have done and (-->) the HttpClient 4.x "translation" if I have found it (Only parties who ask me problems) :
CODE:...........
I don't know if that is correct. This has caused problems because the packages are not named similarly, and some methods too. I just need documentation (I haven't found) and little help.
In my Android client I want to receive JSON objects from a server. By googling I found a lot of different possibilities how to best parse the InputStream from the Server, but most of them wrote their own parser. Isn't there a library which does this parsing for me? Or how should I best implement it by myself?
View 4 Replies View RelatedI'm attempting to make a simple homebrew game engine/framework in android. I have the "engine" as a library project that handles all of the graphics rendering, game activity, and whatnot. Essentially, the library project has a class GameMain which has a background image, an array of drawables, and a few functions (the most important is a run() function). The projects that use this library extend this class with their own unique run() function. The idea is that games that use the engine start with their own activity, launch the GameActivity from the library, and pass their unique GameMain child object into the library, which should run the unique run() method thanks to polymorphism.
Getting this to work, however, has been a struggle. I originally attempted to make the GameMain Serializable, which didn't appear to work. I'm now attempting to make it a Parcelable, but it does not appear to run the child objects run() function when called from the library. I'm wondering, are Parcelable objects actually capable of sending Object methods across activities? Am I going about this the wrong way, or am I just having some other weird bug I have not uncovered?
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.

View 2 Replies View RelatedI was wondering what the simplest program for sending an object from my Android phone to my computer wirelessly (via LAN) would be. I have created Java RMI programs with a server and multiple clients, so I have a grasp of the concept. However with android I'm just not sure where to start.
What I am aiming to do is send some sort of information (could simply be text) to my computer and my computer will do an action. I have the GUI interface's and the actions to be carried out all worked out, just the sending of some sort of information is getting me.
I wish to send a list containing objects from server to client and vice versa through httpurlconnection. Elaborating the same, the list contains a set of objects which is defined both in the server and the client. Its just that the server queries a database and sends the object to the client which collects the same and displays it to the user. Please let me know if thats possible and if it is, how would I be able to accomplish that.

View 11 Replies View RelatedI 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?

View 8 Replies View RelatedI'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 = "http://192.168.1.69:8888/sdroidmarshal";
HttpPost postRequest = new HttpPost(url);
String proto = offers.build().toString();
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.
I'm trying to use the Amazon Web Services java sdk jar but it has references to org.apache.commons.httpclient. All I seem to have in my Android sdk is org.apache.commons.http.client, which is a different namespace and obviously causes the build to fail. I'm new to Java and Android dev... is there a way to "map" one to the other or create some sort of symbolic link? If not, does that mean I have to import a "standard" org.apache.commons library?
View 2 Replies View RelatedI am attempting to have my android phone connect to my servlet and send it a certain image. The way I figured I would do this, is to use the copyPixelsToBuffer() function and then attempt to send this to the servlet through some output stream(similar to how I would do it in a normal stand alone java application). Will this way work? If so, what kind of stream do I use exactly? Should I just use DataOutputStream..
