Example for lacation tracking on Android

This example will show how track location position on Android. First we need to define the permission on manifest.xml

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

Now we have to check if the permission is granted or otherwise let the user grant it.

val dangPermToRequest: List<String> = checkMissingPermissions()
if (dangPermToRequest.isNotEmpty()) {
    requestPermissions(dangPermToRequest)
    return
}

To use the location service, we need to get the location manager through getSystemService

locationManager = this.getSystemService(LOCATION_SERVICE) as LocationManager

Now we define the location listener and register it through our location manager.

private val locationListener = object : LocationListener {
    override fun onLocationChanged(location: Location) {
        ...
    }
}

private fun registerToLocationListener() {
    ...
    locationManager.requestLocationUpdates(
        LocationManager.GPS_PROVIDER, 9000, 0f, locationListener
    )
}

If you use an Emulator, you have to define a location or better a route.

1. Go to Emulator settings
2. Open Location -> Routes
3. Search for a location
4. Press Route and add a destination
5. Now press Play Route
