What is the difference of "Notification" and "Push Notification" in Android

Question

I want to use Notification in my Android app but I don't know what is the difference between Notification and Push Notification in Android.

I searched the web about this title but all of them talk about differences in apple products.

Can anyone remark where I should use Notification and where I should use Push Notification?

Answer 1

The main difference between push notification and notification is that the latter are created internally from an application on the device that wants to show user some information, a reminder, some news or updates, and so on. Push notification are "messages" sent from outside the device, for example a server, that triggers an application of the device (which usually handle the incoming message and transform it in a "normal" notification to be displays in the system tray). This is usually made through a public service such as Firebase Cloud Message ( https://firebase.google.com/docs/cloud-messaging/ ) of Google or a proprietary service such as the one that is used by the most common chatting application (Whatsapp, Telegram, ...) .

Indeed the most common example of push notification is the whatsapp notification of new messages that shows up in your phone when another user has sent you a message (so the message comes from outside your phone). Instead, the basic example for normal notifications are the alarm's notifications or the calendar's notifications.
