I'm developing simple chat application, in which I have done chat functionality, means my app user can send and receive chat messages at both end.
But now I want to get chat history of same user, how can I do that? I have tried various things and also done lots of R & D but I don't get required information.
I'm using asamck lib, and openfire server. I added monitoring service plugins on my server, but what is next step to get the history?

I need some clarifications.
I'm using Firebase realtime database.
Now I've to implement a realtime chat between two android devices. I need also push notifications.
So, the solution based on realtime database is to drop because if the app isn't running, it will not handle the onChildAdded event.
I read on the documentation that I can achieve my aim, using the upstream message from the device to the server.
Now, it's written also that we need an app server.
I just want to be clarified the need of the app server (XMPP or HTTP), and which is the entire flow of message m1 sent from the device A, and the notification on the device B.
In my opinion the app server should act as a man in the middle, so:
A ---> XMPP SERVER ---> FCM
FCM ---> XMPP SERVER ---> B
Is this the flow?
On the documentation I can't understand if I'm right or not.
If so, how do I send a message from the FCM back to the XMPP Server?
The notification message is sent from FCM to the client o from XMPP Server?
Please someone clarify me.
Other solution thought by me:
Since I find really powerful firebase realtime database, I thought these solution to walk around the problem:
Create an app server the is listening for onChildAdded and when it changes send a notification to client device.
Creating a background service on the client app listening to onChildAdded and create notification when necessary.
Even all, I don't like these solutions.
Just want to understand the standard and correct way to achieve my aim.
Firebaser and author of the article debated in the question comments here
To send messages to a device with Firebase Cloud Messaging, you need to specify your project's FCM Server Key. As its name suggests, this key should only be used in code that runs in a trusted environment: i.e. a server that you control.
To send device-to-device messages (such as in a 1:1 chat application where the receiving user is not necessarily online) you need two steps:
one user send an upstream message
the other user receives the downstream message
Using Firebase Cloud Messaging and your custom app server code, you can handle step 2. But that still leaves step 1: the user needs to send a message that somehow triggers your code on the app server. There are quite a few ways to do this.
For example you could implement an HTTP endpoint on your app server and have the chat application send the messages there too (in addition to sending to the database).
You could also implement an XMPP endpoint and have the chat application send the message there (again in addition to sending it to the database).
My article suggest yet another way, one that doesn't require implementing an endpoint at all. It uses a node.js script that runs on your app server and is essentially just a client to the database. Whenever this script detects a relevant chat message, it calls the FCM API and sends the downstream message.
This pattern of using the Firebase Database as your endpoint and then using server-side scripts is quite common when using Firebase. We documented it in our classic blog post Where does Firebase fit in your app? (as option 2) and in this article in the Google Cloud documentation.
Developing an application for android and ios with openfire server with asmack(for android). successfully implemented all stuff(one to one chat also group chat). now stuck in how can I implement notification with openfire server specially users get offline, tried with google but it didn't help. Any help appreciate...
If B gets offline and you want A to know about it. Roster is the thing you need. When users subscribe to each other on roster, then When B goes online/offline, All users who subscribed to B will get to know.
If B gets disconnected from your chat server and A sends some message, and you want to have a notification on B, then you need push notification here. As described by #ShoaibGondal "If you are talking about google push, then that is not supported in Openfire unless you find some plugin online or custom changes in your openfire deployment.– Shoaib Ahmad Gondal"
I am creating a simple forum app for ANDROID using Parse. I am stuck at a problem related to notifications
For instance I want that when user A posts a comment in a forum app, user B (who subscribed to that post) will receive a push notification, can I do that using either client code, instead of handling it using Cloud Code, or the REST API? If not then how to I start developing the server side to use cloud code or REST API
Allowing users to send push notifications via the client is bad for security reasons. It's not incredibly difficult to get the application id and client key to an app. Anyone with that information will be able to create their own code that allows them to target whoever they want with push notifications if client push is enabled.

How to make a chat application in android? [closed]
(6 answers)
Closed 9 years ago.
I am developing an Android app in which I have to implement chat messaging. I would like one to one chat or a group chat.
But I have no idea how to start. Please help me with this stuff. Any help will be appreciated.
A simple chat mechanism will have 2 basic functionalities
Send the message to server (with info about the recipient)
Receive the message from server (designated for my user name)
First step is simple, we can create a web service which will accept the message with additional information about recipient(s). We can create it using any server side language.
Step 2, that is fetching the message from server can be done using 2 techniques, Pull the message (using polling) from server, or Push the message from server to android phone
Polling: In this, the android device will keep accessing server after a few seconds to check if there is a message available for user. This again can be implemented using a simple async task at the client side which will keep calling a web service after say 2-3 seconds. This is fine to use if we are planning to enable chatting only when user is accessing the app (no notifications like gmail or facebook), so that we can kill the polling service when not in use (otherwise it will eat up resources).
Push notifications: a better option is to use push notifications. Android provide Google cloud messaging or GCM (http://developer.android.com/google/gcm/index.html) which will help achieve push from server easily. Otherwise you can try a third party API like urbanairship or pushwoosh depending on your requirement. Push notifications will help the user to receive messages even when he is not using the app.
So in nutshell, a webservice to receive the messages and a push notification mechanism should be sufficient to implement a chat service in android.
Little bit about UrbanAirship
I used UA in one of my projects for push notifications as I needed to support both iOS and Android. If you just want to support Android GCM might also be a good option.
Coming back to UA, check this for sample code and usage: https://docs.urbanairship.com/display/DOCS/Home
The way it works is simple, when someone installs the app and is connected to internet, app registers itself to the UA service. A unique code is specified for each installed app (this is the time when you can capture the user name and unique code and store somewhere in your DB). Next UA provides an API using which you can push a message to designated recipient(s), using the unique codes which are available with UA. These messages can be received by android app and used as per the requirement. Even if the app is not running we can show a notification just like when we receive an email or a message
You can use an existing platform like Scringo. It gives you a one-on-one chat as well as group chat (both the client and the server) as well as the push notification service.
Recently, I try to build a chat app in android with XMPP! I installed Ejabberd, and with connection, I can chat with another user with my android app! But now, I have an issue in retrieve chat logs history! I mean that I don't know how to get chat history with Asmack and Ejabberd. I tried reading the smack document, however, I can find nothing!! So, anyone has any suggestion to get chat history with asmack and Ejabberd? Thank very much!
Ejabberd does not necessarily save chat history by default, since that can be a potentially very expensive task. Nor is it built into the core part of the server. There are modules available such as mod_archive that can installed/enabled that would allow you to save some chat history, but as chat history is not part of the core XMPP spec, there is no "standard" way to do it, so it would only work when connecting to your own servers. What you might consider doing instead is archiving your chat history yourself locally. You will notice that this is what most desktop XMPP clients do. Enabling mod_offline would allow you to receive message that were sent to you when you were offline. But there is no special method for retrieving them, they just arrive when you log in.
