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.

All I'm getting so far is a "Connecting" status from the Nexus 7, followed after a few seconds by a "Disconnected" one.
As it is my first attempt at setting up a VPN (both on the server and client sides) I was wondering if there was a log file generated by Android on the Nexus that would give me a clue as to where I'm going wrong.
A similar file on the server side

View 9 Replies View RelatedI have exchange set up on my Droid through the email program that comes with the phone.. Its been working fine until this weekend, really. 3 separate times, it's failed to load my inbox or sync new messages, and it pops up with the unable to open connection to server message.Ive quadruple checked all of my settings, removed my account, re-added my account, refreshed it, and still, it wont sync my inbox and it still shows that message. I even tried installing touchdown, and touchdown wouldnt sync my email either? I didnt like how it kept my contacts all separate from my gmail contacts, so I went ahead and uninstalled it. I REALLY just want to use the regular exchange email program..But get this, I am able to sync my sent mail though, and Im able to SEND email messages, just not receive them.
We have our own exchange server for our company, and we have 4 other people in our office running exchange on their phones, (2 Motorola Droids, 1 Droid X, and an HTC 6800...) Nobody else is having issues with their phones syncing their email so I know this isnt an exchange issue, but a phone issue instead.Ive run an update (just the *228) on my phone, reset it like 3 times, killed all the apps, and it still wont sync my inbox (just my sent mail..) And again, it'll send email but wont receive it.I know calling or going into a verizon store will be a waste of time.
I recently downloaded K9, having read on here what a good email program it is. I can't get the thing to work with my Yahoo.co.uk account. It's Pop 3. The account works ok with the standard HTC email program, but when I try to set it up using K9, I get "Setup could not finish Cannot connect to server (Unable to open connection to POP server)." I've googled it, I tried setting it up without using wifi, and tried changing settings to IMAP and port numbers, but just can't get anywhere with it.
View 6 Replies View Related"Unable to open connection to server." That's the message I'm getting from my Droid every time I try to set up a connection to my web hosts SMTP server using IMAP. The settings I put in the Droid work fine on my laptop and on my blackberry.
I've tries using ports 25, 1025, 465 and 587. I even tried 143 and 585. Anyone have any clue why this is happening? Anyone else having trouble with SMTP/IMAP connections to their email server? Right now I can't send emails from the Droid and that's a HUGE problem.
I am looking for a way to automate my Android phone connecting to an SSH server when the phone connects to an unsecured wifi network. My understanding is that this is adequate to keep my traffic from being sniffed by DroidSheep (Android), FireSheep (Windows), or other packet sniffers.
I'm using this guide to connect my Android phone to the SSH server: link HERE
Is the Tasker app the best way to do this?
- if yes: how do I trigger the launch of the SSHTunnel when the trigger event (connection to unsecured wifi network) occurs?
- if no: what is a better way?
Note: I did a search for SSH (link HERE) and did not see anything covering this.

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)

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 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 am able to connect my PC to the local tigase server setup locally(I am using Smack API). 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 1 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 guess it is a old issue, and I have googled the related message in the group, and I think I do not miss anything: 1. I made the MD5 fingerprint of the SDK debug dertificate by keytool, and I applied the maps api key, refer to //code.google.com/android/ toolbox/apis/mapkey.htm 2. I added the apikey into my layout xml; 3. I added <uses-library android:name="com.google.android.maps"/> into my manifest xml;
but I still met this error, btw ,I have set the http_proxy in setting table, and I can use browser to visit network. has somebody succeeded to get a map on emulator other than device? could you give me some tips about 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.
