Introduction

This advanced tracking plugin, offered by Mappls plugins for react native, allows one to track the path traveled with smooth animation along the route. The smooth animation by plugin directly depend upon the frequency of the provided information on the current location, time, and speed of the vehicle being tracked to the plugin. More the Merrier!

API Usage

Your Mappls Maps SDK usage needs a set of license keys (get them here) and is governed by the API terms and conditions. As part of the terms and conditions, you cannot remove or hide the Mappls logo and copyright information in your project.

The allowed SDK hits are described on the user dashboard page. Note that your usage is shared between platforms, so the API hits you make from a web application, Android app or an iOS app all add up to your allowed daily limit.

Prerequisite

• Sign Up and Log In
  • Go to the Mappls Dashboard and sign up or log in.
• Create Separate Apps for Android & iOS
  • Create two separate apps in the Mappls Dashboard:
    • One for React Native Android
    • One for React Native iOS
• Install Dependencies
  • Install all required dependencies for Mappls SDK integration into your React Native project.
• Android Configuration
  • Download configuration files for your Android app (associated with the Package Name and Signing Certificate SHA-256).
  • Add the following configuration files to the app-level root directory of your Android project:

    <appId>.a.olf  
    <appId>.a.conf
    

• iOS Configuration
  • To initialize and authenticate Mappls SDK on iOS, include the following configuration files in your project bundle:

    <appId>.i.olf  
    <appId>.i.conf
    

  • In your ios/Podfile, add the following line inside the post_install block:

    $MAPPLS_MAPS.post_install(installer)
    $MAPPLS_TRACKING_WIDGET.post_install(installer)
    

Getting Started

• Install Mappls Tracking Widget

`npm i mappls-tracking-react-native`

Optional Parameters

• speedInMillis(number): To set the animation speed in milliseconds.

• resource(string): To set the route resource. Default to "route_eta".

• profile(string): To set the profile for the route. Default to "driving".

• trackingIcon(string): To set the tracking icon (like a RiderIcon) in the north-up direction on a map.

• trackingIconSize(number): To set the tracking icon size.

• routeChangeBuffer(number): The distance defined for call reroute for the provided current location.

• polylineRefresh(boolean): To remove the route at the same time as the rider progresses along the route.

• latentViz(string): To set the string value for smooth visualization when rider suddenly jumps off-route. Incurs an additional routing call.// [Acceptable values for this is : jump,fly & route]

• latentVizRadius(number):

• cameraZoomLevel(number): To set the camera zoom level.

• fitBoundsPadding (number): To set the padding for the fitbound.// default 80

• fitBoundsDuration(number): To set the duration for the fitbound.// default 1000 millis

• enableDestinationRouteConnector (boolean): To set boolean value for hide/show connector line from the last route point on road to actual input destination coordinate // default false

• trackingSegmentCompleteCallback(trackingData: TrackingData) : retrieve the remaining distance, you can access the relevant data within the trackingData object that the callback provides. For example...

  trackingSegmentCompleteCallback={(event:any) => {
              console.log("remainingDistance", JSON.stringify(event))
            }}
  

• enableSim (boolean): enable or disable rider simulation when rider location is inconsistent.

• maxSimDis (number): maximum distance till which simulation will be active after the last location injected into the widget.

• simSpeed (number): This value is speed in metres/sec at which the rider simulation will be started at. The ride simulation will be slowed at a defined rate below this speed after every few metres to enable a very smooth and slow animation till the time a fresh active location is injected tot the widget or max simulation distance is reached.

• lastRiderLocation(number[array]): This parameter is used to pass the last known location (long,lat) coordinates of the rider.

• orderId (string): This parameter is used to add some unique id related to tracking

• trackingEventCallback (eventName:string,eventValue:string) : attributes to be returned for each event in real-time on occurrence of each event.

  • aerialDistance : displacement from last location to new location
  • roadDistance : from last location to new location (if and only if new location is within routeChangeBuffer distance of route polyline)
  • latentViz : A boolean flag indicating if crow-fly/jump happened from old location to new location. When crowFly is false, it indicates that the new location is route adherent.
  • routeRecompute : A flag in string that indicates success/failure of route-recompute when tracking SDK internally calculates new route. This will happen when crowFly is true, and new location's distance from route polyline is greater than buffer distance.

   trackingEventCallback={(eventName:any,eventValue:any) =>{
          console.log("trackingEventCallback",eventName + ":::::::" + eventValue)
        }}
