Offline Airport API

A simple Android Library to get Nearest Airport(s) from latitude,longitude using a local json data (~28K airports).

Local data is sourced from here.

Why(s) and Good(s)

• Ability to get nearest airport without a webservice call.
• Can be used as a cache mechanism in case webservice call takes longer time.
• Can be used as a fallback mechanism if webservice fails.(Server error, user is not connected to internet)

Bad(s)

• Although data set is exhaustive, it's not an updated one.
• Library size (~ 1.6 MB)

Usage

Create a Request

    AirportRequest airportRequest = new AirportRequest();
    airportRequest.setLatitude("28.632907");
    airportRequest.setLongitude("77.219536");

Initialize library

    OfflineAirportApi offlineAirportApi = new OfflineAirportApi(this);

Get Single Nearest Airport

    //Must be called asynchronously
    AirportResponse airportResponse = offlineAirportApi.getNearestAirport(airportRequest);

Get Multiple Nearest Airports

    //Set a minimum distance limit from current location. Has a default value of 50,000m
    offlineAirportApi.setDistanceLimit(25000);
    //Must be called asynchronously
    ArrayList<AirportResponse> airportResponses = offlineAirportApi.getNearestAirports(airportRequest);

Check Sample App for Usage.

TODO

• Check for more sources of data.
• Handle calculation asynchronously within the library.
• Ability to detect location using GPS from library.
