Android :: Options For Client Server Communication
Nov 6, 2009
I'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.

I 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.

I 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.
****SERVER****
[HIGH]
public class Additional_Server {
private static ServerSocket serverSocket;
private static Socket clientSocket;
private static InputStreamReader inputStreamReader;
private static BufferedReader bufferedReader;
private static String message;
[Code] ....
****CLIENT****
[HIGH]
import android.os.Bundle;
import android.app.Activity;
import java.io.IOException;
import java.io.PrintWriter;
[Code] .....

I 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?

I 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.

I have an application client/server and I want to install this application in differente machines. The server is located in IP_SERVER, listening port 7000. I want to start a cliente in another machine with IP_Y and connect to the server on the different machine.
I've started the server and I've created the socket like this: ... new ServerSocket(7000);
I've started the client and I've created the socket like this: ...new Socket(SERVER_IP, 7000)
But the client did not connect to the server. I've already set the INTERNET_PERMISSION. Any suggestions how to do it? Anybody else have already done a client/server application that communicate between different machines?

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.

I have a simple client-server app on android. the android service communicates with the server via tcp sockets. the service sends a simple String to server which works. the server processes the string and sends back an object to the android service. the object implements the serializable interface. the object "leaves" the server successfully but at the point where the android service receives the object (socket.readObject()

I am new to developing applications for android but have developed my first app. I have following questions.
1. Is it possible to create a client server app? I mean the application on one phone acting as server and applications on other phones sending/receiving data from it?
2. Create a wifi network (may be using bluetooth) for the above client server app. The idea being not to use the mobile service provide network but rather a local network.

Seems like it should be pretty straightforward. In the main menu I chose "email" and added my pop servers URL and the next line asks for the password which I entered however it will not let me highlight either the "manual set up" or the "next" icons in a gray bar just below the password box. Tried it several times now. Certainly a Droid should be able to handle pop server mail??

I am able to connect to the local server by using client Beem for android.My XMPP Domain name of the server is my PC name "mwbn43-1" and IP address is "192.168.0.221"(I am able to ping this server from Android Terminal Emulator). In Beem Settings there is an Advanced option where I can specify server I want to connect with(which I have given as IP address).If I don't set this option I am not able to conect.Now here is the snippet of the code I have used for my android client.

Such like massager app, client/server framework, using tcp long connection using heart beating packet. Cause TCP connection, so when local network is disable or changed, connection would be disconnected. But to the client, it may not be known right now till the next interaction with the SERVER. Is there a general solution to reconnect automatically when network is available again? For example, a broadcast receiver would be triggered when network connection changed, and reconnect when available? Further more, how to check the network capacity, auto-connect the wanted one cause good bandwidth?

I'm going to creating an Android App where 4 players can connect together and play the game together, now the connection is most probably going to be bluetooth, quicker and my app wont be using a online server. But I'm trying to work out which would be best, P2P or client server, a peer to peer connection would be good, but is 4 users connected together ok and stable using bluetooth? A client server solution would be the host would turn into a wi-fi hot spot while 3 others connect to that wifi.

Going to grab myself an HTC magic today. Done some searching around and can not wait to finally ditch this POS iPhone.
Anyhow, I'm looking to see if anyone has any info on a mt-daap server and client.
If you don't' know what it is you can look at
Firefly Media Server :: Home Page
it's a clone of the iTunes music sharing service. It allows you to share your music collection over your network.
I have a firefly server setup and share my music colection with all my systems. As well I VPN into my network from work/coffee shop and can listen to my tiny 500GB music colection on my netbook (ubuntu 9.10 btw)
I would love to be able to do the same with my new phone. My curent iphone(jailbroken) has a firefly server that i can share the music from it's ipod side. But alas no client.

I've had a Desire for two weeks now. I was in love with the phone... until this problem came up.
I use Outlook and Microsoft Exchange -- and had read all about how Android synced easily. And it did at first. Then, 10 days ago, the calendar stopped syncing. I got a "Client/Server conversion error," and no sync. The problem only effected my calendar -- mail and contacts were synced just fine. After reading a few forums, I did a "Remove account," re-installed the account. It worked fine again. No big deal.
Then it happened again today. I did the Remove/re-install thing again, and again it was cured. Until six hours later.
Is anyone else having this problem with their calendar/exchange sync? Any solution guesses?
Without being able to sync my phone to Outlook, the Desire I love so much is somewhere between frustrating and infuriating.

I have created the Client-Server application. At the Server site i have used the AIDL to impliment the interfaces in my Service class. At Client site i have exposed the AIDL interfaces and have one Activity that mainly do the IPC mechanism , i mean ServiceConnection, bindService and then call the Serivce of the Client site. But i am getting the error i mentioned during the bindService call.
Could you please let me know the steps mainly i have to follow to run the Client -Server Application. For time being i am running the Client .apk first and then the Server .apk, but the server one giving me error.
It would be great if you could let me know what all permission short of thing to take care, as my Client and Server code are placed at different APks, so do i need to import the Client project in my Server Project, if yes then how to impliment that.
