UnreachableOnly

Proposals, which are triggered because the active route is considered unreachable, are automatically accepted. This means that when they are added to the navigation session via the com.tomtom.sdk.navigation.RouteAddedListener with com.tomtom.sdk.navigation.RouteAddedReason.AvoidBlockage or com.tomtom.sdk.navigation.RouteAddedReason.WithinRange reason, the com.tomtom.sdk.navigation.ActiveRouteChangedListener is invoked to announce that a the better proposal is automatically selected as active without requiring actions from the integrator. A route is considered unreachable if it contains a blockage or, in the case of EV navigation, there is a significant risk of running out of battery charge.

For all other proposals, when they are added to the navigation session via the com.tomtom.sdk.navigation.RouteAddedListener with a com.tomtom.sdk.navigation.RouteAddedReason.BetterRouteProposed reason, it's up to the integrator to decide whether the proposed route should be selected as active with com.tomtom.sdk.navigation.TomTomNavigation.selectActiveRoute or ignored.
