These messages can be sent at any time and even if your app is not running at that time. So, I will provide the series of articles on this Book Reading App, in upcoming articles I will integrate other Huawei Kits.

Push Kit

Huawei Push Kit is a messaging service developed by Huawei for developers to send messages to apps on users’ device in real time. Push Kit supports two types of messages: notification messages and data messages. You can send notifications and data messages to your users from your server using the Push Kit APIs or directly from the AppGallery Push Kit Console.
