I would like to create a instant message application. The problem I faced is that how can I know other has sent a message to me and my mobile can get a notification from server?
Developing Client side Application is must to notify the Update from server,
Have to run the back ground services continuously to find the update.
If you are accessing the android inbox message , no need to create the own service , we can use the android service here

I am currently aiming to make an app in Android Studio that allows one user to push a button and another user to receive a push notification as a result. How might I do this?
You're going to need a server to act as an intermediary. Set up an API endpoint that your app can call to request a notification, and have your server dispatch a message to the receiving device using something like FCM.
I come from the JavaEE development and I'm totally new to android app developement and I'm a bit confused how to implement my requirements. I have a server, where the user has to authetificate and can perform CRUD-Operations via REST-webservice. When a specific event is triggered server-side I want to send a notification to the app. The user should recive the notification even when the app is not running at the moment.
So now my questions:
What do I need on client side so I can recieve this notifications even when the app is not running? Or do I recieve them even if the app is not running? The data input from the notification needs to be safed app-side.
How do I send a notification from my server if the event is triggered? Do I have to use FCM(/GCM?) or can I directly send notifications from my server to the app?
Any help is appreciated!
Typically, 'instant notifications' are done via websocket severs, for mitigating the process of setting one up yourself, people typically use something like Pusher, which has a library available for java, or you can obviously use FCM/GCM. In conjunction with this document you should be able to keep the service running on the andriod app even when running in the backround so you can still send notifications, just remember you'll have to still attempt to detect if they have internet connection or not when sending out those notifications.
I want to create a service whose function will not be known forehand. When the app is started, the function (which is decided at run time) to be performed is sent from the server to the mobile.
For example, when the app runs server may ask to list all installed apps in the mobile and app replies. When developing the app we dont know that server is going to ask for installed apps. App should be able to respond to any command from the server.
Android app acts like a client to all commands from the server.
Apply the push notification, while on receive the notification, start your service with the tasks sent by the server.
As the app disconnects it stops getting messages from xmpp server. For background notification purpose, I am using GCM service. Now, Just like WhatsApp I want my app too to receive the messages in background and save them in sqlite.
Is it necessary for this task that my app would always be connected to
xmpp server?
Will it not load the xmpp server Since, so many sessions the server
will have to keep alive?
Don't set keep alive for less then 10 minutes this will load the server.
When app is in the background then you have to send push notification via gcm for android and apns for iPhone. For this to implement you need to implement plugin on openfire.
1 up if you like the answer. Email me at cvofjaspreet#gmail.com I can provide you code for plugin also.
So I have found a way to send push notifications to Android in my case I am using Parse. Does Android however allow a developer to send a push notification that will instead launch an application on the users device? My usage case is in the event that the application crashed and for some weird reason did not restart I can check on the database side and see that the user hasn't transmitted any data in 6 hours and thus issue a push notification that would restart the application.
Certainly! Just set the Intent to your application and startActivity
I had to use this for the same reason in my job!
