I am looking to set up push notifications in my phonegap project for both Android and iOS. My goal is for users to receive a message whenever there is an update on an event.
However, I am struggling to grasp the process of achieving this.
Is it possible to "check for updates" when my app is not actively running? Can this be accomplished with phonegap?
Any assistance or guidance would be greatly appreciated. Thank you!
My confusion lies in understanding the process at hand.
For those unfamiliar, PhoneGap (or its open source counterpart Cordova) serves as an application that essentially packages your website to function like a real app. When the app is inactive, the website remains so as well. Therefore, if you wish to receive notifications, this functionality cannot be achieved solely through the website.
Instead, PhoneGap can facilitate communication with the underlying Operating System (such as iOS or Android) to enable notification registration. This can be accomplished by either creating a custom plugin within PhoneGap or utilizing existing ones like phonegap-plugin-push.
The aforementioned plugin typically involves three main steps:
1) Initialization - Setting up for different Operating Systems
var push = PushNotification.init({
"android": {"senderID": "12345679"},
"ios": {"alert": "true", "badge": "true", "sound": "true"},
"windows": {}
});
2) Registration - Identifying when notifications are triggered
push.on('registration', function(data) {
// data.registrationId
});
3) Action - Defining response actions
push.on('notification', function(data) {
// data.message,
// data.title,
// data.count,
// data.sound,
// data.image,
// data.additionalData
});
Aside from the responses provided in a similar question, there are two additional points I'd like to touch on.
One option is to explore the use of websockets. Tools like Primus allow for real-time data transmission from your server to designated clients.
However, it's worth noting that if your application is running in the background, in deep sleep mode, or completely shut down, websockets may struggle to deliver the information.
In such cases, utilizing services like Google Cloud Messaging or equivalent alternatives becomes essential. These solutions typically involve cordova plugins that establish a background service alongside your app to ensure push notifications can still be received even when the app is inactive.
