The best navigation apps for Android and iOS

Reference Sample App A simple navigation app built as a reference design for customers, and to demonstrate best practices for architecture and UX required for a typical navigation application. We use this key to associate your requests to APIs with your account. You can find your existing keys or create a new one at: These areas are designed so that you can reuse the concepts and code in your own projects. Comments have been added to the sample code where appropriate to clarify “why” something is necessary — and where the intention or logic might not be obvious from the code itself.

Sample Activities and Supporting Components: Sample App Activities RouteSelectionActivity The RouteSelectionActivity is responsible for allowing a user to define the starting and destination locations for a desired route.

It provides a search form to allow a user to search for a location to add to a route request. The map also handles long presses to drop a pin on the map and add a location to the route. A network request is made to the MapQuest RouteService with these coordinates as parameters — along with any RouteOptions, which can be used to specify restrictions such as “avoid highways”, “avoid toll roads”, etc.

One or more alternate Routes are returned from the RouteService, and these are plotted on the MapView. The user chooses one desired Route to navigate — this is passed along to the NavigationActivity to start navigation using the NavigationManager.

Before a route is passed to the NavigationActivity we present a UI Dialog to get the user’s consent for traffic data collection. Their preference is to be set by calling NavigationManager. Setting this value is required before a route can be started. NavigationActivity The NavigationActivity is responsible for navigating a route.

It sets up listeners for navigation events and updates the UI when they occur. The NavigationActivity binds to the NavigationNotificationService described above — which manages the NavigationManager instance — and once connected, starts navigation using the route provided by the RouteSelectionActivity.

The abstract class LocationProviderAdapter in the SDK provides a generic “wrapper” for any location-provider of your choice — for example, a native Google location service, a “mocked” location-provider e.

It is recommended that developers use this implementation, or, if they wish to provide their own, adhere to the recommended guidelines specified in the LocationProviderAdapter javadocs to ensure that other components in the Navigation SDK behave correctly. Here’s a description of the key methods in the LocationProviderAdapter class: Abstract Methods public void requestLocationUpdates The concrete implementation of this method should immediately initiate recurring location updates at an appropriate interval, typically at a minimum interval of approximately once per second.

It should also set up the LocationListener member variable to call onLocationChanged Location location on every location update. If the location update interval is too long, the Navigation Manager might not perform as expected; conversely, if it is much shorter than once per second, this could prove wasteful of battery-life without any real benefits to navigation accuracy or user-experience. Concrete Methods public void initialize Initialize the adapter.

This is called by the navigation manager when it is initialized. Sub-classes that override this method should always call super. This is done when as soon as possible after the navigation manager is deinitialized. Note that if navigation is in progress, the call to deinitialize the adapter will be deferred until navigation ends.

If no listeners existed, this will cause recurring location updates to be requested from the underlying location service. We use Mapzen Lost as the default location provider because we feel it provides good location results without needing to pull in the Google Play Services dependency. For more info on the Mapzen Lost library, see: Our team also uses custom “mocked” implementations of LocationProviderAdapter that fire a pre-defined set of route-locations — which are useful, for example, when writing functional tests for a navigation application.

However, if developers want to have the navigation experience continue while the app has been backgrounded — and also to persist through various Android OS actions e. To handle this use-case correctly, a Foreground Service should be created, started, and bound to your application.

In the sample app provided, NavigationNotificationService is an example Android Service which maintains an instance of NavigationManager. It is used to ensure navigation continues in the case that the app is backgrounded and reclaimed by the OS. Activities in the sample app can bind to the service and retrieve the navigation manager. Navigation Prompts: This is accomplished by means of a simple interface, PromptListener, which can be added to the NavigationManager to handle each prompt event.

The best navigation apps for Android and iOS No matter your destination, these seven navigation apps will show you the way Posted on October 2, Google has photographed and mapped most of the globe and is constantly updating its databases to add new roads, bypasses, and even update the images on Google Street View. You can even book appointments from the app on services like OpenTable, Lyft, or Uber. Waze is constantly updated by the millions and millions of users using it to get from one place to another, funneling data about travel times, traffic, and even fuel prices back to Waze, to help other users. It also works with Android Auto in your car and is definitely worth a try if you commute every day. Even though both are owned by Google, it can be tricky to choose between Waze and Google Maps , so we recommend trying out both to find the right one for you.
