How to Create an UX Design for Android Auto
If you're interested in creating a new app for Android, read this article to learn more about how to create an intuitive UI. This article covers Split-screen functionality, Notification widgets, Mirroring apps, and Basic design principles. It will also help you create a better app overall. It may not be an Android-exclusive app, but it's a start. There are some common design principles you should consider when designing for Android.
Split-screen functionality

One of the most popular changes that Android Auto has made is a new split-screen mode that works across screen sizes. Previously, you needed to scroll through apps to switch between them, but now the split-screen mode will keep media and navigation always on your main screen. Moreover, start ups will adapt to the different screen sizes and shapes. This new feature will help you take full advantage of the functionality of your car's infotainment system.

Google's latest update will make it easier for drivers to maximize the display area in the car. The updated Android Auto system will enable drivers to use the full display, and it will also reinvent the Android Auto experience. Split-screen functionality will be available for wide-screen head units, and it will be possible to view both the navigation view and the media player. Google says that it's designed to make it more intuitive to switch between apps.
Notification widgets

The first thing you should know about Notification widgets for Android Auto is that you cannot install them officially. This means that you can only install widgets in the split screen mode. However, it's not impossible to add widgets to the auto's display with a third-party application. Widgets for Auto is a simple open source application that will allow you to install a widget of your choice and make it display on the car's screen.

Notification widgets for AndroidAuto are available on the AA Store, but you can also download them from a Telegram channel. Installation is easy: simply tap on Widgets for Auto in the AA Store, then select the app you want and wait for it to install. You will need to give permission to install apps from unknown sources. You'll need to enable this setting to install Widgets for Auto.
Mirroring start ups

If you're a driver, you may already have the CarLink app, which mirrors the display of your mobile device to your car's screen. Designed to save you time, this app lets you see the map on your car's display and control music playback without fumbling with cables. Not only does it save time, but it can also reduce the amount of time you spend getting in and out of the car.

Google is testing a new screen-mirroring app for Android Auto. This may use Google Cast to let you mirror the screen of your phone onto the dashboard of the Android Auto. Another development is an SMS button in the incoming call window. Pressing the button will send a quick text message to the caller, or reject the call. While it's not rolled out yet, the feature is a welcome addition.
Basic design principles

Creating a UI for Android Auto is a bit different from designing for mobile. The Android Auto SDK provides the media service interfaces, which define the UI, playing content, customizing UI, and app-specific actions. This media service consists of a navbar, the main app content area, a status bar, and app controls on the steering wheel. The content area displays the app launcher and the main application in use.

The Android Auto interface uses rich contextual awareness to blend predictable functions with timely help. Effective apps are built on patterns for common tasks and display timely information only when it is relevant. The Android Auto experience promotes a seamless transition from your mobile phone to your vehicle, and beyond. It also leverages your personal ecosystem, giving you access to the same information wherever you are. However, you can still make your app compatible with Android Auto without having to re-invent the wheel.
