Directions SDK

What is it?

It's a library written in Kotlin to utilize Google Directions API calls and convert response to data classes.

How do I use it?

Add dependency

allprojects {
 repositories {
  ...
  maven { url 'https://dl.bintray.com/rozkminiacz/Directions-Android-SDK' }
 }
}
implementation : 'me.rozkmin.directions:core:1.0' 

Create instance of DirectionsApiClient:

class AnotherBoringMapActivity : Activity(){
    val directions : Directions by lazy {
        DirectionsSdk(getString(R.string.google_directions_key))
    }
}

Transit options

You can specify severalDirections API request parameters:

val transitOptions = TransitOptions(
                mode = MODE.WALKING, 
                whatToAvoidArray = arrayOf(AVOID.FERRIES, AVOID.HIGHWAYS))

Request route between points

class AnotherBoringMapActivity : Activity(){
    fun getSuggestions(from: LatLng, to: LatLng){
            directions.getSuggestions(
                    origin = Position(from.latitude, from.longitude),
                    destination = Position(to.latitude, from.longitude))
                    .subscribe({ t : GeocodedResponse ->
                        //process routes
                    },{
                        //error
                    })
        }
}

Retrieve route steps:

fun processData(geocodedResponse: GeocodedResponse){
    val stepStart: Position = geocodedResponse.routes[0].legs[0].steps[0].start
    val stepEnd: Position = geocodedResponse.routes[0].legs[0].steps[0].end
}

Make use of detailed polyline

fun processData(geocodedResponse: GeocodedResponse){
        val positions: List<Position> = geocodedResponse.routes[0].overviewPolyline.getDetailedWaypointsPositions()
}

I want to improve this library!

Sure! Pull requests are welcome! Any reasonable extension will be added.
