There are many new features in Android 8.0 Oreo. Now, some external changes have been found underneath the hood, they are new material design guidelines.

Google describes how the company thinks that material design should be applied in the official guidelines. That fact is the guidelines are slightly modified for Android 8.0 Oreo.

The most noticeable change is how icons are built. In the new Android version, developers define a foreground and a background. The background can be cropped by the manufacturer or maker, the foreground then remains intact. Also, additional effects can be added. The updated guidelines provide exact specification for how to build an icon in Oreo style.

You know, Google has already made changes to notifications in Android 7.0 Nougat, and now the changes expanded in Android 8.0 Oreo. For example, notifications are now grouped into channels and allowing the user to specify whether and how to receive them in certain channels. The guidelines provide more information on how different notifications cab be placed in channels. Additionally, a template has been added and developers can use for messaging notifications.

The instructions for grouping application settings are also simplified. The guidelines are quite simple. In general, it is better to use sub screens if there are many settings. And, horizontal lines must be used to separate groups of settings.

Another addition to the material design guidelines is a page for offering offline content. Google indicates that it’s important that an app is offline and it must be clearly indicated if the app’s functionality is restricted when there is no connection. Google points out that it’s a good idea to offer content offline. You know, keeping offline content will also reduce data usage. When offline content is downloaded, the user must be able to remove it to free up space.Google.Material.Design
