View 2 Replies View RelatedI have a simple Java client application (Android app). I have to write a PHP server application which receives a request from the Java client application to write some data to a MySQL database or read some data from the MySQL database. It should respond with a status message (Write failed/success) or the data requested respectively. How would I get the Java client send a request and receive the reply from the PHP program and how would the PHP program receive the request and send the reply? I have googled about SOAP and REST architectures, but looking for a simple tutorial which will allow me to implement this simple program.
View 2 Replies View RelatedI'm currently in the research phase of my dissertation project.My project is a ticket booking system for a mobile device and I have chosen to target Android.I anticipate the need for a client/server architecture with a central server, and so am currently looking at how Android could communicate with such a server. The server would grant the client access to ticketing information, and the client would send information about ticket bookings to the server. I'm looking at Java EE for the server as Java is the language I'm most experienced with.I'm aware that Android comes with java.nio and java.net, as well as some org.apache packages, but am also looking for libraries/technologies that would be possible to use with Android.
View 1 Replies View RelatedI am trying to create a basic application that transmits GPS co ordinates of the device to a server. I am a complete noobie to socket programming.
As a stepping stone, I am following a tutorial, that creates the server, and the android client, it is designed to send an input from the user to the server and the server prints it on the console.
I'm becoming quite familar with how to set up the basics of the server and the client i.e. opening ports etc. The problem with this is, when hit send, the app crashes, when tested on the emulator, there is obviously an issue, but I can't see it.
When I test with device, and hit send, there is nothing printed to the console. I've attached both the client and server code below, the ip in the code below is for the emulator, I change this to my device ip with testing with it.

I have seen some solutions using HttpsURLConnection. and SSLContext. I would like to go with httpclient not URLConnection as I require to manage cookies and al. I am looking for your exert advice on above matter..............

View 3 Replies View RelatedI wrote a TCP socket client, an android application. On my emulator, it can successfully connect to a TCP sever running in my PC. But, when I deployed the the apk into my real phone, HTC g4, it dosen't work. An exception was raised said "java.net.SocketException: Network unreachable". The situation is, my handset was connected to my PC via USB, and no other connections were available. How can my android application connect to a PC server in the case. I don't know if we can use socket over usb connection. If yes, then why my application doesn't work. If no, then how?
View 2 Replies View RelatedI have an application that needs to send messages, repeatedly to the server. I'm currently using AJAX from the phone's browser and it works fairly reliably, but, as with all things cell-phone, not 100%. I'm curious if using Android and opening a socket to the server would give me any additional reliability, or if it would suffer from the same communication troubles that hinder the AJAX transmission.

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?
Could someone please suggest me a good/efficient way to communicate with the server. I could think of two options 1) Use http post methods to send data to a php script at the server which would later call the google api's written in another java program (jar)or use php to use google api's (if its possible) to find nearby restaurants and send the list back to client. 2) Use simple java socket programming. The server has a jar file that supports multi threading and it does the job of finding restaurants and sending the list.
View 4 Replies View RelatedI just purchased a Samsung Intercept through Virgin Mobile and am hoping I can find a simple application to store my clients information using it.
I am a Hair Colorist and I have been using a Sony Clie in the past to keep my client info up-to-date, but it finally died. I am hoping my new phone can keep track for me now.
Here is what I need the app to do.
1) Clients Name (so I can easily search for client)
2) Phone Number (so I can call them)
3) Address (not mandatory, but would probably be good)
4) Client's Hair Color Formula (text area where I can write down their color formula)
5) Date of last appointment (and maybe their upcoming appointment)
Does anyone know if there is something out there like this already? It seems like it should be a basic app, but I am BRAND NEW at this, so I have no idea .

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.
I wonder if it's possible to authenticate an app with a http server. THe server API does not require user name or password, but I'd like to expose the server API to a particular app only (so that it cannot be abused by other program). At this point I think it's impossible but figure it won't hurt to ask.

View 2 Replies View RelatedWe are designing a system with a PC base station and 100 Android mobiles communicating over WiFi. They will use XLM-RPC as the method of mobile to base station communication. However, sometimes the base station needs to broadcast a message to all mobiles. Should we use "http server push" for this, i.e., have the base station leave the connections open to all the mobiles? Is there a better way? Publish-subscribe is possible, but doesn't seem mature on Android yet.
