Launch Navigator Cordova/Phonegap Plugin

Cordova/Phonegap plugin for launching today's most popular navigation/ride apps to navigate to a destination.

Platforms: Android, iOS and Windows.

Key features:

• Single, clean API to abstract away the gory details of each 3rd party app's custom URI scheme
• Detects which supported apps are installed/available on the user's device
• API to detect which features are supported by which apps on which platforms
• Out-of-the-box UI for app selection which remembers user choice
• Growing list of supported apps

Launch Navigator is also available as a React Native module.

I dedicate a considerable amount of my free time to developing and maintaining this Cordova plugin, along with my other Open Source software. To help ensure this plugin is kept updated, new features are added and bugfixes are implemented quickly, please donate a couple of dollars (or a little more if you can stretch) as this will help me to afford to dedicate time to its maintenance. Please consider donating if you're using this plugin in an app that makes you money, if you're being paid to make the app, if you're asking for new features or priority bug fixes.

General concepts

App detection, selection and launching

• The plugin will detect which supported navigation apps are available on the device.
• By default, where this is more than one choice, it will display a list of these to the user to select for navigation.
  • This is done using native UI elements
• However, the plugin API allows you to programmatically:
  • check which apps are available on the current device
  • check which apps support which navigation options
  • launch a specific app for navigation

Geocoding and input format of start/destination locations

• Some navigation apps require that destination/start locations be specified as coordinates, and others require an address.
  • See App location support type wiki page for details of which apps support which location types.
• By default, this plugin will appropriately geocode or reverse-geocode the locations you provide to ensure the app receives the location in the required format.
• However, geocoding requires use of a remote service, so an internet connection is required.
• If navigate() is passed a location type which the selected app doesn't support, the error callback will be invoked if:
  • geocoding is disabled by passing enableGeocoding: false in the options object
  • there is no internet connection to perform the remote geocode operation
  • geocoding fails (e.g. an address cannot be found for the given lat/long coords)

Remember user's choice of navigation app

• If the built-in app selection mechanism is used, the plugin enables the user's choice of app to be locally persisted, meaning they don't have to choose every time.
• By default, this as the user to confirm they wish their choice to be remembered.
• See the appSelection section of options for the navigate() function for more details.
• See the "Advanced Example" project] in the example repo for an illustrated example.

Adding support for more apps

This plugin is a work in progress. I'd like it to support launching of as many popular navigation apps as possible.

If there's another navigation app which you think should be explicitly supported and it provides a mechanism to externally launch it, open an issue containing a link or details of how the app should be invoked.

Don't just open an issue saying "Add support for Blah" without first find out if/how it can be externally launched. I don't have time to research launch mechanisms for every suggested app, so I will close such issues immediately.

Installing

The plugin is registered on npm as uk.co.workingedge.phonegap.plugin.launchnavigator

IMPORTANT: Note that the plugin will NOT work in a browser-emulated Cordova environment, for example by running cordova serve or using the Ripple emulator. This plugin is intended to launch native navigation apps and therefore will only work on native mobile platforms (i.e. Android/iOS/Windows).

Using the CLI

$ cordova plugin add uk.co.workingedge.phonegap.plugin.launchnavigator
$ phonegap plugin add uk.co.workingedge.phonegap.plugin.launchnavigator
$ ionic cordova plugin add uk.co.workingedge.phonegap.plugin.launchnavigator

PhoneGap Build

Add the following xml to your config.xml to use the latest version of this plugin from npm:

<plugin name="uk.co.workingedge.phonegap.plugin.launchnavigator" source="npm" />

OKHTTP Library

• This plugin uses the OKHTTP library on Android to access Google's remove Geocoding service
• The library is included at Android build time via Gradle
• If another plugin in your Cordova project specifies a different version of the OKHTTP library than this plugin, this can cause a Gradle version collision leading to build failure. See #193.
• You can override the default version of the library specified by this plugin by specifying the OKHTTP_VERSION plugin variable during plugin installation:
  • cordova plugin add uk.co.workingedge.phonegap.plugin.launchnavigator --variable OKHTTP_VERSION=1.2.3
• You can find the version of the library currently specified by this plugin in the plugin.xml

Usage examples

Simple usage

Navigate to a destination address from current location.

User is prompted to choose from available installed navigation apps.

launchnavigator.navigate("London, UK");

Navigate to a destination with specified start location

launchnavigator.navigate("London, UK", {
    start: "Manchester, UK"
});

Navigate using latitude/longitude coordinates

Coordinates can be specified as a string or array

launchnavigator.navigate([50.279306, -5.163158], {
    start: "50.342847, -4.749904"
});

Advanced usage

Navigate using a specific app

launchnavigator.isAppAvailable(launchnavigator.APP.GOOGLE_MAPS, function(isAvailable){
    var app;
    if(isAvailable){
        app = launchnavigator.APP.GOOGLE_MAPS;
    }else{
        console.warn("Google Maps not available - falling back to user selection");
        app = launchnavigator.APP.USER_SELECT;
    }
    launchnavigator.navigate("London, UK", {
        app: app
    });
});

List all of the apps supported by the current platform

var platform = device.platform.toLowerCase();
if(platform == "android"){
    platform = launchnavigator.PLATFORM.ANDROID;
}else if(platform == "ios"){
    platform = launchnavigator.PLATFORM.IOS;
}else if(platform.match(/win/)){
    platform = launchnavigator.PLATFORM.WINDOWS;
}

launchnavigator.getAppsForPlatform(platform).forEach(function(app){
    console.log(launchnavigator.getAppDisplayName(app) + " is supported");
});

List apps available on the current device

launchnavigator.availableApps(function(results){
    for(var app in results){
        console.log(launchnavigator.getAppDisplayName(app) + (results[app] ? " is" : " isn't") +" available");
    }
});

Supported parameters

Different apps support different input parameters on different platforms. Any input parameters not supported by a specified app will be ignored.

Platform-specifics

Android

• Running on Android, in addition to discovering which explicitly supported apps are installed, the plugin will also detect which installed apps support using the geo: URI scheme for use in navigation. These are returned in the list of available apps.

• By specifying the app option as launchnavigator.APP.GEO, the plugin will invoke a native Android chooser, to allow the user to select an app which supports the geo: URI scheme for navigation.

• Google Maps on Android can be launched in 3 launch modes:

  • Maps mode (launchnavigator.LAUNCH_MODE.MAPS) - launches in Map view. Enables start location to be specified, but not transport mode or destination name.
  • Turn-by-turn mode (launchnavigator.LAUNCH_MODE.TURN_BY_TURN) - launches in Navigation view. Enables transport mode to be specified, but not start location or destination name.
  • Geo mode (launchnavigator.LAUNCH_MODE.GEO) - invokes Navigation view via geo: URI scheme. Enables destination name to be specified, but not start location or transport mode.
  • Launch mode can be specified via the launchModeGoogleMaps option, but defaults to Maps mode if not specified.

Windows

• The plugin is compatible with Windows 8.1 or Windows 10 on any PC and on Windows Phone 8.0/8.1 using the Universal .Net project generated by Cordova: cordova platform add windows or cordova platform add wp8 (for windows phone 8.0)

• Bing Maps requires the user to press the enter key to initiate navigation if you don't provide the start location. Therefore, if a start location is not going to be passed to the plugin from your app, you should install the Geolocation plugin into your project. By default, if the geolocation plugin is detected, the plugin will attempt to retrieve the current device location using it, and use this as the start location. This can be disabled via the enableGeolocation option.

iOS

"Removing" Apple Maps

• Since iOS 10, it is possible to "remove" built-in Apple apps, including Maps, from the Home screen.
• Not that removing is not the same as uninstalling - the app is still actually present on the device, just the icon is removed from the Home screen.
• Therefore it's not possible detect if Apple Maps is unavailable - launchnavigator.availableApps() will always report it as present.
• The best that can be done is to gracefully handle the error when attempting to open Apple Maps using launchnavigator.navigate()
• For reference, see this SO question and the Apple documentation.

Apple Maps launch method

This plugin supports 2 different launch methods for launching the Apple Maps app on iOS.

• Specified by passing the launchModeAppleMaps option as a launchnavigator.LAUNCH_MODE constant to navigate()
  • launchnavigator.LAUNCH_MODE.URI_SCHEME: use the URI scheme launch method. Default if not specified.
  • launchnavigator.LAUNCH_MODE.MAPKIT: use the MapKit class launch method.

URI scheme launch method

• Launches the app using the Apple Maps URI scheme
• The default method used by the plugin.
• Supports input location types of both coordinates and address string without requiring remote geocoding service (works offline)
• Doesn't support specifying nicknames for start/destination locations.

MapKit class launch method

• Launches the app using the MapKit class to launch Apple Maps
• Only supports input location type of coordinates without requiring remote geocoding service (works offline)
• An input location type of an address (formatted as a single string) requires use of remote geocoding service (requires internet connection)
  • MapKit class input requires an address which is formatted as an address dictionary, in which the address is split into known fields such as street, city and state.
• Support specifying nicknames for start/destination locations.
• Provides additional launch options which are not available via the URI scheme launch method.

App-specifics

Lyft

On both Android and iOS, the "ride type" will default to "Lyft" unless otherwise specified in the extras list as id.

See the Lyft documentation for URL scheme details and other supported ride types.

99 Taxi

On both Android and iOS, the extra parameters client_id and deep_link_product_id are required by 99 Taxi

• client_id should follow the pattern MAP_*** where *** is the client name given by the 99 Team.
  • If not specified defaults to client_id=MAP_123
• deep_link_product_id identifies the ride category
  • Currently supported values are:
    • 316 - POP ride
    • 326 - TOP ride
    • 327 - Taxis ride
  • If not specified defaults to deep_link_product_id=316

On Android, 99 Taxi is currently the only app where options.start is a required parameter when calling navigate()

• If navigate() is called without a start location and the selected app is 99 Taxi, the error callback will be invoked and the 99 Taxi app will not be launched
• In order for this plugin to automatically provide start location to 99 Taxi (if it's not already specified), the native Android implementation needs to be enhanced to:
  • check/request runtime permission to use location
  • add the necessary permission entries to the AndroidManifest.xml
  • check/request high accuracy location is enabled (no point in requesting a low-accuracy city-level position if you want a pickup at your exact current address)
  • request a high accuracy position to determine the user's current location
  • handle errors cases such as:
    • User denies location permission
    • User denies high accuracy mode permission
    • Location cannot be retrieved
• Currently, I don't have time to do all of the above just for the case of 99 Taxi
  • However I'm willing to accept a PR request which implements the necessary native Android features.
• Otherwise/until then, you'll need to manually specify the start location for 99 Taxi
  • If the current user location is required, you can use cordova-plugin-geolocation to find this.

Reporting issues

Before reporting issues with this plugin, please first do the following:

• Check the existing lists of open issues and closed issues
• Check your target country is supported for turn-by-turn by the native navigation app
  • Apple Maps country list for iOS
  • Google Maps country list for Android
  • Bing Maps country list for Windows Phone
• If possible, test using the example project to eliminate the possibility of a bug in your code rather than the plugin.

When reporting issues, please give the following information:

• A clear description of the problem

• OS version(s) and device (or emulator) model(s) on which the problem was observed

• Code example of calling the plugin which results in the observed issue

• Example parameters (locations or place names) which results in the observed issue

Issues which fail to give a clear description of the problem as described above will be closed immediately
