The requested interval in milliseconds. This setting is only approximate.

priority
The requested accuracy. This setting influences the battery usage. The 
following are possible values (constants from LocationRequest):

PRIORITY_NO_POWER: Fetches passive updates only if other 
requestors actively request updates

PRIORITY_LOW_POWER: Updates only on “city” levels

PRIORITY_BALANCED_POWER_ACCURACY: Updates only on “city street 
block” levels

PRIORITY_HIGH_ACCURACY: Uses the highest possible accuracy 
available
This value will be internally adapted according to available permissions.

smallestDisplacement
This is the smallest displacement in meters necessary for an update 
message to be fired.
With that location request setting, we check whether the system is able to fulfill our request. 
This happens in the following code snippet:
val REQUEST_CHECK_STATE = 12300 // any suitable ID
val builder = LocationSettingsRequest.Builder()
.addLocationRequest(reqSetting)
val client = LocationServices.getSettingsClient(this) client.checkLocationSettings(builder.
build()).
addOnCompleteListener { task ->
try {
val state: LocationSettingsStates = task.result.

Log.e("LOG", "LocationSettings: \n" +
" BLE present: ${state.isBlePresent} \n" +
" BLE usable: ${state.isBleUsable} \n" +
" GPS present: ${state.isGpsPresent} \n" +
" GPS usable: ${state.isGpsUsable} \n" +
" Location present: " +
