How do Android Developers handle Push Notifications?

They handle push notifications using Firebase Cloud Messaging, which basically allows the developer to send notifications from the Back-end server to the users’ devices. They use Notification Channels so that they will not violate the users’ will by giving all the control for notification settings to the user. They will design notifications that contain actionable buttons, rich media, and other interactive elements involving increased user engagement. Among the key features to be implemented are handling notification payloads and testing if notifications work seamlessly on different devices.
