I know how to implement GCM in my App but I don't know how to build a server able to send notification to ALL the users.
I need something quite simple (just sending notification), could you advise me any services and tutorial in order to set up the server?
I wish something not to complex, because everything that I will need from my app is receiving whether simply notifications to display or to tell the app that some new data is available for downloading.
Thank you!!
Prerequisite for GCM Application
Google API Server Key
GCM RegId of the Android Device to communicate via GCM

If you're using PHP, you could use this approach to send GCM message to your client refer this
You could setup your own local server on PHP using AMPP. refer this
Probably, the simplest way is to add a cloud endpoint module refer this. Then, write a simple service refer this that sends the messages. Finally, let Android Studio deploy it.

I want to develop a website that will be able to send push notifications to a mobile application that would be able to run on both android and iOS.
For the last couple of years, I am working as a web developer so developing the website is not something that I am worried about, but I have never developed a mobile application before, the mobile app would only receive notifications from the website so the main functionality would be in the website.
Can anyone suggest me what the best approach is and what I have to learn to be able to do this?
Thank you in Regards
I guess, you have 2 options.
You can either use Firebase FCM
https://firebase.google.com/docs/cloud-messaging/
or use a third party which is called OneSignal
https://onesignal.com/.
If you are looking for an easier way then I recommend using OneSignal instead. You just need to define API Key in your build.gradle and initialize OneSignal in onCreate().
The best approach, in my opinion, would be to use firebase (https://firebase.google.com/products/cloud-messaging/). I think it is better because it is a unique framework for both ios and android and you don't need to worry about the user device when sending the message(you could build an interface in your backend code to handle this but why doing something that already exists and it is free).
The flow is something like this:
on the first start the app(either ios or android) must send its firebase ID to your server so that you can store it (simple http request will od it) and set up a listener for the incoming push messages
when you need to send a push message all you need to do is an http request and you can trigger it with js from your website. The request will contain data such as the firebase id of the receiving device(which you have previously stored)
Firebase Cloud Messaging also have some really nice features like upstream messages(push messages from the device to the server, but you need an xmpp server to listen for them) and topics to send the same notification to many users at the same time
I think the best approach would be to create a node server where the website would be running on and then use Firebase Cloud Messaging (FCM) to send notifications
EDIT: FCM supports both Android and iOS
I am buiding an android app which will be receiving notifications from my server. This means all my users which is above 1 million, will receive notifications from my server. I know parse and google cloud messaging(GCM) can do the push messages but please I want to know the best out of this two (parse and GCM) so I can implement it. Thanks in advance.
If you look at https://parse.com/tutorials/android-push-notifications you can see:
The Parse library provides push notifications by using Google Cloud Messaging (GCM).
So you have to register your app to GCM console to send push notification in anyway.
When to NOT use parse.com?
If you already have a backend service, you can easily implement push notification since there are plenty of third part libraries for different platforms such as node.js, php etc.
When to use parse.com?
If you don't have backend-service and you just want to send push notifications also if you don't want to spend your time by setting up server stuff then you can go with parse.com
NOTE: Facebook shuts down parse by January 2017 so please consider it.(http://blog.parse.com/announcements/moving-on/)
Android push notification is a service used to send messages directly to the Android Mobile Devices.
There are several ways we can implement Android push notification.
Google Cloud Messaging(GCM)
Parse Notification(Parse.com)
You are asking which one is the best way to implement :
The standard way is using GCM (Google Cloud Messaging) but there are some alternatives like Parse Notification,Which is easier to use.
If you need to handle Json Push messages,Refer this link
Steps involved in send Push notifications:
Developing the application involves two parts:
GCM Server Application – Create Web application using Php to send message to User via GCM Cloud server
GCM Client Application – Create Android application which receive message sent from GCM Server Web App
For More Informations regarding to GCM server and Client Application
Parse uses GCM and uses own service for Kindle
Please Go with google cloud messaging(GCM) .It is very easy to integrate in android app. the problem with parse in some case device token or registration id is not register at their database so User of parse does not get push notification.In case of GCM we can sure for device token
So my recommendation is GCM
Hope this will help you.
I am trying to implement android push notification by using GCM. But, in all the tutorials that I have referred so far, I get one or more PHP files. Is it not possible without PHP, because I don't know PHP. Any help will be appreciated.
I f you want to implement GCM you'll need a mediator file php/.net etc which acts as communicator between your server and the GCM server.This file pass the message to be delivered along with the projectid(registered with google console)to GCM server.So that GCM server can send push messages to all mobile devices regisytered under the corrosponding projectid.You can use this based on your purpose.
You don't have to have PHP for GCM, you can use any server side language i.e. Java (J2EE), Python, etc. But what you must have is a server.
See what android is saying about GCM here
A full GCM implementation requires both a client implementation and a
server implementation. For more information about implementing the
server side, see Implementing GCM Server.

I want to implement notification of news or article in Android.User can put the new article or news on the server after that i want to show notification in my app through PHP MySql.Can someone help me how to do this.Thanks to appreciate.
PHP is a server side process - it only runs when a user/app/service requests the page.
MySQL is a server based database. It's not "connected" to your app.
Your app must then "poll" your website (it has to request data from it periodically). This is best done using an XMPP type service. You can find a lot of info on XMPP - basically, it's complicated to setup and run. It probably isn't worth doing unless you've already done it.
Alternatively, you can use an existing XMPP service. Google Cloud Messaging (GCM) is an excellent option for most Android devices (any that has Google Play installed... so, it won't work on an Amazon Fire phone, for example). It's not "easy" to setup, but they do a lot of really hard stuff for you. Also, there are a lot of references for setting it up, like this from Google:
https://developer.android.com/google/gcm/client.html
You can use Google cloud messaging to display Notification or You need to create a service that always ping your server for new message.
please try 1st options its better.(2nd options is worst because it use more battery & internet data )
You can use google cloude messaging service to send notificaion in device so please register your application on google service all step are cover below link.
Open below link and follow step

You can use GCM (Push notification) and implement the notification generated method inside onMessage method.
For reference use this linkAndroid Push Notifications using Google Cloud Messaging (GCM), PHP and MySQL
What you are looking is Google cloud messaging.
For Gcm you have to write a server in your case is php server.
For Gcm server code or for testing purpose refer this link.
Android: Test Push Notification online (Google Cloud Messaging)
But firstly it is best to learn about GCM itself and it's mechanism.
For this you can refer this link.
https://developer.android.com/google/gcm/index.html
You have to do some settings in Google console which are all explained in this article including the android side code.
Hop i helped you.
I'm new in android development. I'm trying to develop an app in which a user can send a request to another device running the same app and it should return a response/notification to the sending device.
I googled it and found that GoogleCloudMessaging can be used for that. But all the tutorials say that it can be used to send messages from server to apps. I need to know how the reverse can be done, ie send messages from app to server..
Please provide some tutorial.
Any help is appreciated.
Thanks..
If you want to send data to your server, you can use rest communication.
Here a tutorial
Step 1: Call a server side script*(REST api/ Webserices)* from your android application using HttpPost/HttpGet,
Step 2: Wait for response coming from server and use it.
Note: don't forget send all needful data for your request from your app to server by httppost.
