Kotlin - Menentukan Rute Terdekat dari Lokasi menggunakan Google Map

Tutorial ini membahas mengenai bagaimana membuat rute terdekat dari lokasi menggunakan google map, dimana untuk menentukan rute terdekat dari lokasi tersebut membutuhkan API dari Google Developers anda bisa membaca dokumentasi dibagian sini.

Java - Menentukan Rute Terdekat dari Lokasi menggunakan Google Map

Sebelum Anda mulai membuat proyek ini, Anda membutuhkan API keys supaya aplikasi dapat berjalan dengan Google Maps, untuk membuat Google Maps API key disini

API yang digunakan untuk membuat rute terdekat dari lokasi, yang dimana untuk output format menggunakan json. 

http://maps.googleapis.com/maps/api/directions/json?parameters

Dari API diatas ada parameter yang harus diprelukan antara lain:

  • origin - Lokasi asal dengan mengisikan berupa alamat, nilai dari garis lintang (Latitude) dan bujur (Longitude) atau ID tempat dimana anda ingin menentukan rute.
    • Jika anda mengisikan berupa alamat anda perlu memasukan pada parameter origin 
      origin=Mataram
    • Jika anda mengisikan dengan nilai lintang dan bujur anda harus memasukan bagian parameter origin 
      origin=-8.594848, 116.105390
    • Jika anda mengisikan dengan nilai ID anda harus memasukan bagian parameter origin 
      origin=place_id:DhIJSS-JXXauEmsRUcIaWtf5MzE
  • destination - Lokasi tujuan dengan mengisikan berupa alamat, nilai dari garis lintang (Latitude) dan bujur (Longitude) atau ID, untuk opsi destination hampirsama pengisian dengan origin.
  • key - Kunci API aplikasi yang harus anda buat untuk ditempatkan di parameter key

Menyiapkan Proyek

Langkah pertama masukan dependencies dibagian file build gradle

implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.google.android.gms:play-services-maps:16.1.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-places:16.0.0'
implementation 'com.google.android.libraries.places:places-compat:1.1.0'
implementation 'com.google.maps.android:android-maps-utils:0.5+'

Download resource disini dan tempatkan dibagain drawable

Langkah Membuat Proyek

Bagian Manifests Masukan Api Keys dibagain value dari metadata.

.....
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<application
.....
<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOU HERE KEYS" />

<service
   android:name=".service.FetchAddressIntentService"
   android:exported="false"/>

</application>

Menambahkan Permission GPS, fungsinya saat aplikasi dijalankan akan tampil dialog untuk meminta mengaktifkan GPS.

        }
    }

    companion object {
        internal const val REQUEST_LOCATION = 199
    }
}

Membuat validasi supaya terhubung ke jaringan internet dengan membuat fungsi check koneksi, kasusnya jika terhubung ke jaringan maka aplikasi diteruskan jika tidak maka keluar dari aplikasi dengan popup “Kesalahan jariangn periksa koneksi anda”.

package com.kodetr.googlemap.utils

import android.content.Context
import android.net.ConnectivityManager
import android.net.NetworkInfo

/**
 * Created by kodetr on 18/05/19.
 */

object Connections {
    fun checkConnection(context: Context): Boolean {
        val connMgr = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        val activeNetworkInfo = connMgr.activeNetworkInfo
        if (activeNetworkInfo != null) {
            if (activeNetworkInfo.type == ConnectivityManager.TYPE_WIFI) {
                // connected to wifi
                return true
            } else if (activeNetworkInfo.type == ConnectivityManager.TYPE_MOBILE) {
                // connected to the mobile provider's data plan
                return true
            }
        }
        return false
    }
}

Selanjutnya membuat penampungan konstan, jadi anda tidak menginginkan anda bisa menerapkan langsung pada aplikasi anda.

package com.kodetr.googlemap.utils

/**
 * Created by kodetr on 19/05/19.
 */

object Constants {
    const val DIRECTION_URL_API = "https://maps.googleapis.com/maps/api/directions/json?"

    const val LOCATION_DATA_EXTRA = "$PACKAGE_NAME.LOCATION_DATA_EXTRA"
    const val SUCCESS_RESULT = 0
    const val FAILURE_RESULT = 1
}

Membuat aksi dimana digunakan untuk mengambil alamat menggunakan intent dengan menerima berupa result dari lokasi yang ditentukan oleh kordinat blue point pada GPS, untuk menerapkannya dengan membuat Intent Service dan menjalankan dengan memanggil service pada manifest yang sudah diterapkan pada langkah sebelumnya.

        receiver!!.send(resultCode, bundle)
    }

    companion object {
        private const val TAG = "FetchAddressIS"

Selanjutnya adalah membuat Parsing data dari url API dengan menggunakan lib json, Membuat model berupa interfece finder listener, class model Distance, class model Duration dan class model Route.

class Distance(var text: String, var value: Int)

class Duration(var text: String, var value: Int)

class Route {
    var distance: Distance? = null
    var duration: Duration? = null
    var endAddress: String? = null
    var endLocation: LatLng? = null
    var startAddress: String? = null
    var startLocation: LatLng? = null
    var points: List<LatLng>? = null
}

interface DirectionFinderListener {
    fun onDirectionFinderStart()
    fun onDirectionFinderSuccess(route: List<Route>)
}

            routes.add(route)
        }
        listener.onDirectionFinderSuccess(routes)
    }
}

Menambahkan fungsi decode untuk setiap poin yang ditampung dalam list berupa langitude dan longitude untuk mencari rute paling dominan dengan menampilkan berupa garis pada map.

private fun decodePolyLine(poly: String): List<LatLng> {
    val len = poly.length
    var index = 0
    val decoded = ArrayList<LatLng>()
    var lat = 0
    var lng = 0

    while (index < len) {
        var b: Int
        var shift = 0
        var result = 0
        do {
            b = poly[index++].toInt() - 63
            result = result or (b and 0x1f shl shift)
            shift += 5
        } while (b >= 0x20)
            val dlat = if (result and 1 != 0) (result shr 1).inv() else result shr 1
            lat += dlat
            shift = 0
            result = 0
        do {
            b = poly[index++].toInt() - 63
            result = result or (b and 0x1f shl shift)
            shift += 5
        } while (b >= 0x20)
            val dlng = if (result and 1 != 0) (result shr 1).inv() else result shr 1
            lng += dlng
            decoded.add(LatLng(lat / 100000.0, lng / 100000.0))
        }
    return decoded
}

Jika anda sudah mengikuti langkah dengan benar maka struktur akan seperti gambar berikut.

Bagian activity utama yaitu MapsActivity yang harus anda terapkan terlebih dahulu, berupa Permission dan cek Connection.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    checkLocationPermission()
}

if (!Connections.checkConnection(this)) {
    Toast.makeText(this, "Kesalahan jaringan periksa koneksi anda", Toast.LENGTH_SHORT).show()
    finish()
}

Buat request permission dari fungsi checkLocationPermission beserta dengan fungsi popup.

private fun checkLocationPermission(): Boolean {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.ACCESS_FINE_LOCATION)) {
            ActivityCompat.requestPermissions(this,
                        arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
                        MY_PERMISSIONS_REQUEST_LOCATION)
        } else {
            ActivityCompat.requestPermissions(this,
                        arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
                        MY_PERMISSIONS_REQUEST_LOCATION)
            }
            return false
    } else {
        return true
    }
}

Membuat fungsi untuk pencarian menggunakan Auto Complete dengan penerapan pada parameter url API sebagai destination.

private fun setupAutoCompleteFragment() {
    val autocompleteFragment = fragmentManager.findFragmentById(R.id.place_autocomplete_fragment) as PlaceAutocompleteFragment
    autocompleteFragment.setOnPlaceSelectedListener(object : PlaceSelectionListener {
        override fun onPlaceSelected(place: Place) {
            searchLocation = place.latLng
        }

        override fun onError(status: Status) {
           Log.e("Error", status.statusMessage)
        }
    })
}

Mencari rute terdekat dengan melakukan aksi pada fungsi DirectionFinder dengan memasukan parameter origin, destination dan api key kedalam fungsi tersebut.

DirectionFinder(MapsActivity.this, origin, destination , api_key);

Menerapkan proses Direction Finder untuk menampilkan distance dan duration dengan origin dari blue poin ke destination yang ditandai dengan marker merah dengan menampilkan berupa garis dengan warna merah.

override fun onDirectionFinderSuccess(routes: List<Route>) {
    progressDialog!!.dismiss()
    polyLinePaths = ArrayList()
    originMarkers = ArrayList()
    destinationMarker = ArrayList()

    for (route in routes) {
        map!!.moveCamera(CameraUpdateFactory.newLatLngZoom(route.startLocation, 15.5f))
        (findViewById<View>(R.id.tvDistance) as TextView).text = route.distance!!.text
        (findViewById<View>(R.id.tvTime) as TextView).text = route.duration!!.text

        destinationMarker!!.add(map!!.addMarker(MarkerOptions()
                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
                .title(route.endAddress)
                .position(route.endLocation!!)))

        val polylineOptions = PolylineOptions()
                .geodesic(true)
                .color(resources.getColor(R.color.colorPrimary))
                .width(10f)

        for (i in route.points!!.indices) {
            polylineOptions.add(route.points!![i])
        }

        polyLinePaths!!.add(map!!.addPolyline(polylineOptions))
    }
}
