I'm looking for a protocol/API to implement a video chat application. In this app, the clients connect to a server and when two clients start chat, they don't send/receive data to/from server! Actually I want the clients connect to each other straightly. I want this on iPhone and Android.
I've searched, and found XMPP protocol, but I'm not sure it let p2p connection.
Anyway, is it possible?
you can work for the XMPP Protocol which is specially made for chatting purpose.
That helped me a lot in my work. They might have an android version out now.
you can use WIFI or BlueTooth to do P2P apps.

I'm investigating how can I establish call with the help of webrtc by openfire or ejabberd server. I want to use one of it for signaling (change sdp, check status of call etc).
I have experience how to do it with SIP, but I haven't no Idea how I can do that with the help of XMPP.
May be someone worked with it and know where I can find information about it?
You can use XMPP Jingle to negotiate WebRTC calls. This is an XMPP spec dedicated to VoIP.
I am writing a mobile trading app (android/ios) and i need suggestions on the best way to connect the app to the server (messageQ)
If i use raw TCP connection , would my users have a problem if they are behind corporate wifi's (protected by firewalls)? If yes, in that case, is web socket a better solution?
With the backend server, after researching with zeroMq, i believe a full fledged broker like rabbitmq is a better option to start with. Now , if i use a web socket connection from my native app, Rabbit MQ has a sockJS-AMQP bridge . But i am not sure, if there is a java and iOS web socket client to speak to sockJS server .
Any experienced views is greatly appreciated
Have you considerer to use MQTT?
If you don't need AMQP you can also use directly an MQTT broker, such as http://mosquitto.org/ or http://www.hivemq.com/
Here (https://github.com/owntracks) you can find some ready libraries for iPhone and Android.
In order to solve the the firewall problem MQTT is available over HTTP.
You can read here:

This post can also help you : (https://www.ibm.com/developerworks/community/blogs/sowhatfordevs/entry/using_mqtt_protocol_advantages_over_http_in_mobile_application_development5?lang=en)
For a iPhone application I used directly MQTT and as server RabbitMQ with the MQTT plug-in

I hope it can be useful
I am building a mobile device that needs to send realtime information to other devices. I have considered XMPP but I do not have a server, so the communication must be only between the devices.
Is there a way to communicate using XMPP between mobile devices without a server (Or using the mobile devices as servers)?
Is Sockets a good idea ? i.e. Having a ServerSocket and client Socket and communicating this way.
Is there a smarter way? I have heard of jWebSocket but I dont really know how it works or if it's worth it.
EDIT
The process is as follows:
I'm using Parse as a server/backend http://parse.com
When the user runs the app, a user list is retrieved from the parse server
The user then has (Could have) the ip of other clients and then attempt to communicate with them.
Problems
1. Parse does not support a XMPP server or other type of servers
You might look at using an IRC client library like http://jerklib.wikia.com/wiki/JerkLib_Wiki. This way you can use a public IRC server to communicate with your other devices...
I've not used it, but I did bookmark it for further reading because I thought it a novel concept ...
I hope it helps...
I'm using C2DM in my Application to send data from mobile to mobile
But C2DM uses Google server(lacks data confidentiality) to redirect messages to device.
Is there any other way for sending data from mobile to mobile directly without any third party server?
I dont want to use SMS in my App.
Base on requirement (1) Without third party server (2) Between 2 mobiles.
Your options are limited to these:
WiFi Direct (Ad Hoc Network)
http://developer.android.com/guide/topics/wireless/wifip2p.html
Bluetooth
http://developer.android.com/guide/topics/wireless/bluetooth.html
NFC
http://developer.android.com/guide/topics/nfc/index.html
You clearly said "no third party server". But may I suggest xmpp. I've had good luck with smack derived jars and OpenFire. You get a lot of flexible and easy to use functionality out of the box. It may be your best bet for chat type applications.
We host our own instance of OpenFire and authenticate against Active Directory. The XMPP protocol provides the user/device addressing, routing, and, optionally, store and forward capabilities.
It also makes it easy to exchange device data with applications written for other operating systems and in other languages. XMPP IQ packets can be used for lookup type transactions without the overhead of a Chat type connection (no presence information, back end XEP-114 plug ins to connect with server side resources).
Not really: your device has to know which device to connect to. You could theoretically do that if you know the IP of the device, but with mobile phones this changes frequently and I'm not even sure if mobile providers will let you connect directly to devices on their network. So, you're at least going to need a 'step' in between the two phones that you can trust to be stable.
What you could do is set up your own server, and let a user (user1) upload messages to your server addressed to a specific sender (user2). When the message is received, you can use C2DM to send a signal to user2's phone, and attach the message's unique identifier to this. When user2's app receives this message, you can proceed to download the message content from your webserver.
If you don't want to use any webserver at all, you're limited to the options mentioned by Calvin: WiFi, bluetooth or NFC.
Unfortunately having a direct socket connection between mobiles phones is almost impossible as they invariably are behind firewall. BTW also look at https://www.alljoyn.org/ Its an interesting technology as well.
Hello
When i am using my application using WIFI or INTERNET APn it works fine.But provides socket connection error while trying with WAP APN.
Is there anything that i can do to resolve this in android.
Do i need to use any permissions to use my application for WAP?
Please share your valuable suggestions.
Thanks in advance :)
I really don't think it is a permissions issue.
With a WAP data plan you can only connect to standard HTTP ports (ie. 80) and exchange WAP based packets. If your app tries to connect to a different port or exchange non WAP packets, then you'll get an error.
