I am developing chat application using parse. These will be a group chat application.
There are many number of groups possible. I have implemented parse and also have knowledge about it.
But I want to make it real time chat application.
I know I can do it with the help of push notification but having lack knowledge of implementation.
Can you guys please suggest me some other way of doing real time chat or how to exactly work with push notification to make real time chat application.
So here are some queries:
Can I develop group chat using parse ?
Does it feasible solution to use parse for real time chat ?
If yes , then how can i make it real time chat. ?
Parse platform is not suitable for real-time chat applications as it does not support persistent websocket connections. You can still use Parse to send notifications but you should use other providers with real-time support like PubNub or Firebase
Regarding Mo Nazemi's answer, you should also look into Layer and SINCH, sinch alos includes VoIP

I want to implement an instant messaging feature in my android app which will show the chat list of the current user and the conversation with each of them. I want to know which is the best option for doing so because i have heard about various feature like pusher,gcm,xmpp,etc.
I am using retrofit 2.0,php and mysql now in my app to create messaging feature,everything is working out great but but i cant figure out how to show the message received or send in the conversation instantly because for that network request call has to called every time the received or send and i have a feeling i might not be good idea as it will slow down app or something.
Any help will be appreciated
Thanks in advance
If I were you I would look at https://socket.io/. There is also a demo project for Android chat app
I am creating an app using React-Native for the front-end, Java for the back-end and PostgreSQL for the database.
One feature of this app is to allow users to add each other as friends and instant message them - just like other social networks. At the moment, security is not a priority but I don't want to create something that I will have to completely redo when I do have to make it secure!
The goal here is to give each user the ability to send/receive messages to/from their friends. They also need to be able to view the message history with each contact.
I just need some advice on the following points to get me going as I haven't gotten very far on my own:
How should I send messages from the front-end, to the Java server and then to the receiver? This will involve the app having to listen for new messages so would the Socket.IO library be the way to go for this?
How I should store the messages in the database? E.g. have a table for messages with user_ids to be used for retrieval?
I should point out that I am very new to React-Native, databases and networking so I am finding this very challenging!
I will massively appreciate any help and any examples would be fantastic!
You should use WebSocket on the server. Spring supports it
Here's a tutorial I wrote about sending messages from PostgreSQL to the browser using WebSocket, which isn't exactly what you're going to do, but can hopefully get you started:

*I have to make an android application which is basically a chat application.*In this chat app the user can interact with single user as well in a group that means Group chat is also there. I am using php as the back end for database . I have never done this type of work earlier so need some suggestions or guidance.
The options i have seen is as follow :
1. Web-services
2. Socket Programming
3. XMPP using the smack api
Now i am confused in them that which is better to implement chat feature in android. Also i didn't get any sample code for that. One of my team member is asking me to use the socket programming but i didn't get any sample app or anything for socket programming in android. I don't know socket programming this time. How we can connect the our phone to the server and then some other device. Hope you get me what i want to Conway you.
So can any one please guide me and show me the right direction to move on. Also if you can provide me any sample code, that can be really helpful. Any help is appreciated
Another option (besides XMPP, which is certainly a valid approach for chat, since it was designed for that) would be using WebSocket. Using WebSocket would open the possiblity of having a pure browser client as well.
For WebSocket on Android, there is AutobahnAndroid, part of the Autobahn family of WebSocket and WAMP implementations.
WAMP is a RPC and PubSub over WebSocket protocol with multiple implementations. There is also a PHP implementation of WebSocket/WAMP: Ratchet.
Disclaimer: I am author of Autobahn/WAMP and work for Tavendo.
For a basic Socket programming tutorial, you can check HERE and HERE.
However, I suggest using XMPP, as I have mentioned HERE, as it is a protocol designed from the ground up to be used for Messaging.
I developed a chat application using java.But now my challenge is build a chat app in web application.I dont how to proceed.Can we use sockets as done in java.
Please give me a suggestion to get through this.
Thanks in Advance.
I recommend you to use websockets as they're really efficient to exchange in real time (push instead of pull) data between a server and html clients. They're bidirectionnal and roughly equivalent to the sockets you're used to (hence their name). Client-side, they use the same callback based logic than ajax clients but that doesn't mean they're not fast.
Here's a tutorial : http://java.dzone.com/articles/creating-websocket-chat
Googling "java chat websocket" would give you other results.
I want to create an application which send sms from java servlet to mobile device, it's my first time to make like this application.
I found many APIs that supports this feature, actually they confuse me, so I choose one tutorial and follow it,
here's the link of the tutorial http://www.visualgsm.com/tutorial010_send_sms_java.htm
I download VisualGSM Enterprise Server (SMS Gateway) and run it, try to make the steps as mentioned, step 3 in example 2 doesn't work.
I want to know, whether I can make real testing for sending sms? Can I receive an sms on my own cell phone??
what is the best way to send sms? I really confused :(
There's 2 ways to do this: via modem or via API service.
There are various services which provide a gateway to the carriers as a service. They are called aggregators. A few industrial grade ones are mobile messenger and ericsson other consumer grade aggregators are http://www.twilio.com/sms/.
