We designed Android Auto to reduce UI complexity, optimize user +interactions, and lower cognitive load. Effective apps show just enough information +and only provide features that do not require excessive menu interaction and navigation.</p> + +<p><strong>Predictive, yet predictable</strong>. Android Auto leverages rich, contextual awareness +to keep the driver informed about important situations. Timely help is combined with predictable +functions. Effective apps use patterns for common tasks and show timely information only when +relevant.</p> + +<p><strong>Connected</strong>. Android Auto works with apps that drivers already use in other +devices. Android Auto promotes a continuous app experience from phones and tablets to cars, +providing access to user's existing settings, subscriptions, and digital libraries. Experiences +that bring personal content and context from other devices are part of Android Auto.</p> + +<p><strong>Integrated</strong>. Android Auto blends your apps with the vehicle's entertainment +system, creating a truly integrated experience in every car. By using the vehicle's screen and +controls, apps feel tailored to each car.</p> + +<h3 id="uioverview" style="margin-top:25px">UI Overview</h3> + +<p>Android Auto is a new environment that leverages existing UI models where appropiate and adds +new models based on constrains and context. There are three primary concepts for Android Auto: +<strong>Suggest</strong>, a unified place for predictive content; <strong>Demand</strong>, a +pervasive way to interact with voice; and the <strong>Facets</strong>, organized spaces for +primary activities, apps and content.</p> + +<dl> +<dt style="margin-bottom:10px"><strong>Suggest: The Google Facet</strong></dt> +<dd style="margin-bottom:20px"> +Core of continuity and extensibility is contextual stream of Now-like cards, powered by your +apps and notifications. Relevant, timely, and dynamic, the stream organizes likely people, media, +places, and information so drivers can quickly continue their activities or start something new. +Google Now and notifications enable drivers to use the apps and services they know when they are +most relevant. +</dd> +<dt style="margin-bottom:10px"><strong>Demand: The Voice Layer</strong></dt> +<dd style="margin-bottom:20px"> +Voice-enabled tasks lets drivers accomplish their goals without taking their eyes off the road. +Android Auto defines actions and intents that your app can register for. +These are accessible through both persistent UI elements and dedicated hardware controls. +</dd> +<dt style="margin-bottom:10px"><strong>Facets and Templates: App-powered activities</strong></dt> +<dd style="margin-bottom:20px"> +In the car, pages of app icons and different UIs create a distracting and dangerous situation. +Instead, Android Auto apps power templates which help provide simple but customizable UIs +for common interactions such as media or communications. Templates incorporate common behaviors, +such as play/pause or reply to a message, while still letting your app promote its value +and its brand. Apps are organized into facets (or activities) to enable quick access. +</dd> +</dl> + +<p>Android Auto uses the input and output mechanisms in each vehicle to tailor the interactions. +Some vehicles have dedicated hardware controls, while others have primarily touch-based systems. +Android Auto maps common actions and intents across these diverse sets of controls and outputs to +enable you to concentrate on your unique app experience.</p> + + +<h2 id="architecture" style="margin-top:30px">Architecture</h2> + +<p>The Android Auto app projects your app's customized UI on the vehicle's screen.

Your service exposes +your app’s media content, theme resources, and app-specific actions using the methods and +data types specified by the media service interfaces. This simplifies the development +cycle because:</p> + +<ul> +<li>You do not have to maintain a separate project for Android Auto</li> +<li>You can reuse existing functionality from your Android app</li> +</ul> + +<p>The Android Auto client presents the customized UI to users and invokes the +functionality from your service as needed.
