Recently tidied up the internal business logic

A. Processing the content being downloaded

B. Processing the downloaded content

For download business, user sensitivity to events is divided into:

Class A: Whether to start the download, whether the download is complete

Class B: Download progress, about how long it takes to download
1 downloading is a more time-consuming operation, we will not give a screen to show the download progress, but we still want to give the user prompt.

Android notification is specifically to solve this problem, in the Systemui there is a block area to display the notification, it occupies a small place, in the case of minimizing the interruption of user action to give hints.

Notification bar According to the design, the current display strategy is:

For the download to complete, each download to make a prompt, click on the notification, it can go back to launch the download app

For the download there is a situation that shows the specific progress, there are several downloads showing that there are multiple downloads;

The following strategies are used:
