Maneuver.Builder

public Builder(int type)

Constructs a new instance of a Builder.

The type should be chosen to reflect the closest semantic meaning of the maneuver. In some cases, an exact type match is not possible, but choosing a similar or slightly more general type is preferred. Using TYPE_UNKNOWN is allowed, but some head units will not display any information in that case.

public @NonNull Maneuver build()

Constructs the Maneuver defined by this builder.

public @NonNull Maneuver.Builder setIcon(@NonNull CarIcon icon)

Sets an image representing the maneuver.

Icon Sizing Guidance

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

public @NonNull Maneuver.Builder setRoundaboutExitAngle(
    @IntRange(from = 1, to = 360) int roundaboutExitAngle
)

Sets an exit angle for roundabout maneuvers.

Use for when type is TYPE_ROUNDABOUT_ENTER_AND_EXIT_CW_WITH_ANGLE or TYPE_ROUNDABOUT_ENTER_AND_EXIT_CCW_WITH_ANGLE. The roundaboutExitAngle represents the degrees traveled in circulation from the entrance to the exit.

For example, in a 4 exit example, if all the exits are equally spaced then exit 1 would be at 90 degrees, exit 2 at 180, exit 3 at 270 and exit 4 at 360. However if the exits are irregular then a different angle could be provided.

public @NonNull Maneuver.Builder setRoundaboutExitNumber(@IntRange(from = 1) int roundaboutExitNumber)

Sets an exit number for roundabout maneuvers.

Use for when type is TYPE_ROUNDABOUT_ENTER_AND_EXIT_CW, TYPE_ROUNDABOUT_ENTER_AND_EXIT_CCW, TYPE_ROUNDABOUT_ENTER_AND_EXIT_CW_WITH_ANGLE or TYPE_ROUNDABOUT_ENTER_AND_EXIT_CCW_WITH_ANGLE. The roundaboutExitNumber starts from 1 to designate the first exit after joining the roundabout, and increases in circulation order.

For example, if the driver is joining a counter-clockwise roundabout with 4 exits, then the exit to the right would be exit #1, the one straight ahead would be exit #2, the one to the left would be exit #3 and the one used by the driver to join the roundabout would be exit #4.
