Many of platforms based on Apache Cordova project like PhoneGap, Monaca and ionic [e.g. http://cordova.apache.org/#supported_platforms_section]

so if you use one of this platform you can proceed in this tutorial to implement the push notification in your mobile app

and we will use a third-patry Cordova plugin in our tutorial to enable the push notification in our app

https://github.com/phonegap/phonegap-plugin-push

Installation

 

phonegap plugin add phonegap-plugin-push

cordova plugin add phonegap-plugin-push

Obtaining a device token

//senderID: Get Google senderID from Google console
var push = PushNotification.init({ "android": {"senderID": "12345679"},
"ios": {"alert": "true", "badge": "true", "sound": "true"}, "windows": {} } );

push.on('registration', function(data) {
	var deviceToken = data.registrationId;
	$.ajax({
		"url": "http://pushenvoy.com/app/api/save_device/",
		"dataType": "json",
		"method": "POST",
		"data": {
			"device_token" : deviceToken,
			"device_type" : 'android',
			"channels_id" : '1,2'
		},
		"success": function(response) {
			console.log("Device ID "+deviceToken+" sent successfuly");
		}
	});
});

push.on('notification', function(data) {
	// data.message,
	// data.title,
	// data.count,
	// data.sound,
	// data.image,
	// data.additionalData
	alert(data.message);
});

push.on('error', function(e) {
	console.log("Error");
});
