Designing an app with the Android for Cars App Library involves sequencing
templates into task flows and customizing them for the goals of your app and its
users.
Use the library to create apps in the following categories:
To understand the design process at a high level, see the process steps below.
For details of your role and the app library’s role in creating the experience
for users, see Who handles what.
Process steps
Designing with the Android for Cars App Library involves the following steps,
in general:
Define user tasks.
Figure out which tasks are important for users to perform with your app in
vehicles.
Plan task flows.
Choose a sequence of templates to lead users through each task.
Consider driving state.
Make strategic use of parked-only templates and task-flow strategies.
Plan communications.
Choose appropriate communication options for all scenarios in which your app
communicates with users.
Customize your app.
Customize the content of each template to reflect your users’ needs, and
customize styling to reflect your app’s brand.
Who handles what
When you create an app with the Android for Cars App Library, the app library
takes care of many aspects of the app experience, including making it work in a
driving-optimized way in all compatible cars.
What the library handles
What app developers handle
Input: Handling user input to templates via
mechanisms available in specific cars, such as touchscreen or
rotary
Screen sizing: Adapting content to screen
sizes
Screen transitions:
Motion
transition between screens
Consistent, driving-optimized UI: Ensuring that the
UI and interaction patterns are familiar and consistent across apps
Light and dark mode (except as noted below):
Adjusting template features to appropriate mode for ambient light
conditions
UX restrictions based on driving state: Limiting
text or disabling certain features, such as the keyboard, while the user
is driving
Maps for non-navigation apps: Drawing the map in
the Place List (map)
template
Voice input: Processing recorded audio
User flows: Creating customized sequences of
templates that address critical user journeys
Metadata: Providing metadata such as list items and
locations to be pinned on maps
Branding elements: Providing app iconography,
imagery, and custom
accent colors
(with light and dark variants)
Maps (navigation apps only): Drawing and updating
maps (light-themed or dark-themed, as instructed) including a
map for cluster display
if desired
For AAOS, vehicle OEMs take care of:
Vehicle-specific styling: Customizing styles
to integrate with OEM branding and vehicle interiors
