I am using hybrid mobile app with ionic 1.0.I am trying to show notifications for the user via notification bar just like whatsapp and other apps.But i have no idea on how to do this.I searched in internet for notifications for hybrid mobile app.Everywhere i saw some FCM push notifications related to firebase.But i didnt understand how it works.

Right now what i am doing in my app is it is displaying ionic popup if i open the app only.I am able to send message to particular device using deviceId.But i want that popup message as a notification to mobile whenever user turns wifi on or enables mobile data.

Here is my code.

 $scope.testing = function()
 {
 if(ionic.Platform.isAndroid())
 $scope.deviceId = $cordovaDevice.getUUID();
 else
 console.log("not android");
 
 if($scope.deviceId!='')
 $http(
 method : 'POST',
 url : 
 'https://myproject.com/getReportImmediateMessageForMobile?
 deviceId='+$scope.deviceId,
 transformResponse: function(response)
 
 return response; 
 
 ).then(function success(data) 
 $scope.reportImmediate = data.data;
 if($scope.reportImmediate!='')
 var alertPopup = $ionicPopup.alert(
 title: 'Report Immediately!',
 template: $scope.reportImmediate
 );
 
 );
 

After that i am calling interval for 5 seconds to keep checking whether that user with his deviceId received any message or not like this

 $interval(function()$scope.testing();, 5000);

Can anyone tell how to send the message as notification based on deviceId to particular device whenever user gets access to internet connectivity?At present it is working only if i open the app.
