I am trying to connect to a standalone desktop tcp server(java) from tcp client application in android device. But I am not able to connect to that.I tried to write a desktop tcp client and tried to connect to server(remote server). It is working fine.But When I am trying to connecting from android, I am getting a IOException while creating Socket instance.

I am writing an Android app that should exchange data to a server over Bluetooth, with the server side on a PC running Ubuntu, using the bluez library, in C (or C++).
My Android app fails (IOException) when I try to connect to my server socket on the PC.
Here is essentially what I in the java code (in Android, full eclipse project here: http://dl.dropbox.com/u/2968234/ThinBTClient.zip)
CODE:...........
This throws IOException after a timeout of 10seconds or so.
On the server side (in Ubuntu 8.10), I basically set up a Bluetooth server socket, along the lines described in the example bluez/sdp-register.c
Down below is my C++ program. To compile it do
g++ -I/usr/include/glib-2.0/ -I/usr/lib/glib-2.0/include -o bt_server bt_server.cpp -lbluetooth
I can do the reverse succesfully, i.e. create a server socket in Android and connect from Linux, however this is not what I want to do!
I think either the problem has to do with my config of Ubuntu.

I have been fed up of looking for a simple example of rest webservice connecting to Android Application. I know so many people have asked this question before, but there are so many different answers as a theory.
I know I must use restful web-service, rather than SOAP for mobile applications.
I need to create a webservice which is producing JSON, then in Android I can parse the JSON, but the problem is that as I am new to android I am looking for a simple example with both Server and client.
A server : JAVA with Database connection and Restful WebService that produce JSON
Android Client : which parse the JSON result from the webservice
I'm new to android application development.I want to transfer the data between the client and the server.. As of my knowledge for transferring the data from client to server we use HttpClient protocol.Is this protocol is same as REST web services?If i want to send the data in the form of JSON format,then what are the necessary steps that i need to follow?And on the server side what are the steps to receive and parse the data?

View 2 Replies View RelatedI 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 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 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 9 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.

I'm trying to connect my Android app to a PC server using Socket. Unforunately, the PC server doesn't receive any connection request from the app (there's no connection between them). I'm running the app in android emulator.
I've seen many tutorials and discussions in the internet about this problem and I fellow them literally, but still having the same problem that I mentioned above. the android app is running on eclipse emulator and the PC server on netbeans
the PC server source code:
public class server{
ServerSocket server;
public server() {

Now I am facing problems when I want to connect Android Phone to that server over Wi-Fi. 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.

View 3 Replies View RelatedSuch 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?
View 4 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'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.

View 7 Replies View RelatedI'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.
