Constructors

Constructs an empty RoutingInfo.Builder instance.

Methods

Sets the current Step and Distance to display in the template.

A Step with a Maneuver of type Maneuver.TYPE_UNKNOWN will shown here with the given icon.

Image Sizing Guidance

Images in the cue of the Step object, set with Step.Builder.setCue(CharSequence), can contain image spans. To minimize scaling artifacts across a wide range of car screens, apps should provide images targeting a 216 x 72 dp bounding box. If necessary, those images in the spans will be scaled down to fit the bounding box while preserving their aspect ratios.

See CarIcon for more details related to providing icon and image resources that work with different car screen pixel densities.

Sets the next Step.

Unless set with this method, the next step won't be displayed.

Sets an image of a junction for the maneuver.

For example, a photo-realistic view of the upcoming junction that the driver can see when executing the maneuver.

Image Sizing Guidance

To minimize scaling artifacts across a wide range of car screens, apps should provide images targeting a 500 x 312 dp bounding box. If the image exceeds this maximum size in either one of the dimensions, it will be scaled down to be centered inside the bounding box while preserving its aspect ratio. The aspect ratio should be greater than or equal to 1.6 in order to fit the horizontal space fully.

On smaller screens the junction image may result in the hiding of the Lane s, TravelEstimate or next Step.

Sets whether the RoutingInfo is in a loading state.

If set to true, the UI will show a loading indicator, and adding any other routing info will throw an java.lang.IllegalArgumentException. The caller is expected to call Screen.invalidate() and send the new template content to the host once the data is ready. If set to false, the UI shows the actual routing info.

Constructs the RoutingInfo defined by this builder.

Requirements

The RoutingInfo can be in a loading state by passing true to RoutingInfo.Builder.setLoading(boolean), in which case no other fields may be set. Otherwise, the current step and distance must be set. If the lane information is set with Step.Builder.addLane(Lane), then the lane image must also be set with Step.Builder.setLanesImage(CarIcon).
