For extensions, you don't need to add mapbox extensions if you not use the sdk mapbox. As well as the google map sdk.

Add Marker

Google Maps

Use the default method as usual for google maps. Reference for add marker in google maps is here
And code look like this

val markerOption = MarkerOptions()
        .position(latLng)

val marker = map.addMarker(markerOption) // this your marker

Mapbox

For Mapbox, adding marker is little hard, so I create helper for it, and you must coding after setup style

// define marker options
val markerOption = MarkerOptions.Builder() // from 'com.utsman.smartmarker.mapbox.MarkerOptions'
    .setId("marker-id", true) // if marker id need unique id with timestamp, default is false
    .setIcon(R.drawable.ic_marker, true) // if marker is not vector, use 'false'
    .setPosition(latLng)
    .setRotation(rotation)
    .build(context)

// add your marker
val marker = map.addMarker(markerOption)

Move Your Marker

SmartMarker.moveMarkerSmoothly(marker, latLng) 
// or for disable rotation
SmartMarker.moveMarkerSmoothly(marker, latLng, false)

// with extensions for kotlin
marker.moveMarkerSmoothly(latLng)
// or for disable rotation
marker.moveMarkerSmoothly(latLng, false)

Location Watcher Extension

I create location extensions for get your location every second with old location and new location, you can setup realtime level.

Installation

implementation 'com.utsman.smartmarker:ext-location:[email protected]'

// for extensions watcher location, you need some library with latest versions
implementation 'com.google.android.gms:play-services-location:17.0.0'
implementation 'pl.charmas.android:android-reactive-location2:[email protected]'
implementation 'io.reactivex.rxjava2:rxjava:2.2.12'
implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
implementation 'com.karumi:dexter:6.0.0'

Realtime Level

You can setup realtime level for get every second update, locationWatcher.getLocationUpdate(priority, listener)

Use

// define location watcher
val locationWatcher: LocationWatcher = LocationWatcher(context)

// get location once time
locationWatcher.getLocation { location ->
    // your location result
}

// get location update every second
locationWatcher.getLocationUpdate(LocationWatcher.Priority.HIGH, object : LocationUpdateListener {
    override fun oldLocation(oldLocation: Location?) {
        // your location realtime result
    }
    
    override fun newLocation(newLocation: Location?) {
        // your location past with delay 30 millisecond (0.03 second)
    }

    override fun failed(throwable: Throwable?) {
        // if location failed
    }
})

// stop your watcher in onStop activity
override fun onDestroy() {
    locationWatcher.stopLocationWatcher()
    super.onDestroy()
}

Permission helper

If you have not applied location permission for your app, you can be set permission with adding context before listener.

// get location once time with permission helper
locationWatcher.getLocation(context) { location ->
    // your location result
}

// get location update every second with permission helper
locationWatcher.getLocationUpdate(context, LocationWatcher.Priority.HIGH, object : LocationUpdateListener {
    override fun oldLocation(oldLocation: Location?) {
        // your location realtime result
    }
    
    override fun newLocation(newLocation: Location?) {
        // your location past with delay 30 millisecond (0.03 second)
    }

    override fun failed(throwable: Throwable?) {
        // if location failed
    }
})

Don't forget to add location permission android.permission.ACCESS_FINE_LOCATION for your apps

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

Other Extensions

// Convert Location to LatLng for Google Maps ('com.google.android.gms.maps.model.LatLng')
location.toLatLngGoogle()

// Convert Location to LatLng for Mapbox ('com.mapbox.mapboxsdk.geometry.LatLng')
location.toLatLngMapbox()

// use marker as vector for Google Maps
bitmapFromVector(context, R.drawable.marker_vector)

Simple Example

Google Maps

class MainActivity : AppCompatActivity() {

    private lateinit var locationWatcher: LocationWatcher
    private var marker: Marker? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        locationWatcher = LocationWatcher(this)
        val googleMapsView = (google_map_view as SupportMapFragment)

        locationWatcher.getLocation(this) { loc ->
            googleMapsView.getMapAsync {  map ->
                val markerOption = MarkerOptions()
                    .position(loc.toLatLngGoogle())
                    .icon(bitmapFromVector([email protected], R.drawable.ic_marker))

                marker = map.addMarker(markerOption)
                map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc.toLatLngGoogle(), 17f))
            }
        }

        // device tracker
        locationWatcher.getLocationUpdate(this, LocationWatcher.Priority.HIGH, object : LocationUpdateListener {
            override fun oldLocation(oldLocation: Location) {

            }

            override fun newLocation(newLocation: Location) {
                // move your marker smoothly with new location
                marker?.moveMarkerSmoothly(newLocation.toLatLngGoogle())
                                    
                // or use class SmartMarker for java
                // SmartMarker.moveMarkerSmoothly(marker, newLocation.toLatLngMapbox())    
            }

            override fun failed(throwable: Throwable?) {
            }
        })
    }
}

Mapbox

class MainActivity : AppCompatActivity() {

    private lateinit var locationWatcher: LocationWatcher
    private var marker: Marker? = null // from 'com.utsman.smartmarker.mapbox.Marker'

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // setup instance with api key mapbox before 'setContentView'
        Mapbox.getInstance(this, "sk.eyJ1Ijoia3VjaW5nYXBlcyIsImEiOiJjazI1eXFqYzQxcGZjM25ueTZiMHU3aDl3In0.EfIuu2NSv2CacIKEhkXhCg")
        setContentView(R.layout.activity_main)

        locationWatcher = LocationWatcher(this)
      
        locationWatcher.getLocation(this) { loc ->
            mapbox_view.getMapAsync {  map ->
                
                // set style before setup your marker
                map.setStyle(Style.OUTDOORS) { style -> 
                
                    val markerOption = MarkerOptions.Builder() // from 'com.utsman.smartmarker.mapbox.MarkerOptions'
                           .setId("marker-id")
                           .addIcon(R.drawable.ic_marker, true)
                           .addPosition(loc.toLatLngMapbox())
                           .build(this)
    
                    val markerLayer = map.addMarker(markerOption)
                    marker = markerLayer.get("marker-id")
                    
                    map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc.toLatLngGoogle(), 17f))
                }
            }
        }

        // device tracker
        locationWatcher.getLocationUpdate(this, LocationWatcher.Priority.HIGH, object : LocationUpdateListener {
            override fun oldLocation(oldLocation: Location) {

            }

            override fun newLocation(newLocation: Location) {
                // move your marker smoothly with new location
                marker?.moveMarkerSmoothly(newLocation.toLatLngGoogle())

                // or use class SmartMarker for java
                // SmartMarker.moveMarkerSmoothly(marker, newLocation.toLatLngMapbox())  
            
            }

            override fun failed(throwable: Throwable?) {
