AWARE: Locations

CI Status
Version
License
Platform

The locations sensor provides the best location estimate for the users’ current location, automatically. The location data is provided by Core Location.

Requirements

iOS 10 or later.

Installation

com.aware.ios.sensor.locations is available through CocoaPods.

  1. To install it, simply add the following line to your Podfile:
pod 'com.awareframework.ios.sensor.locations'
  1. Import com.aware.ios.sensor.locations library into your source code.

    import com_awareframework_ios.sensor_locations
  2. Open your project ( *.xcworkspace ) and add NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription into Info.plist.

Public functions

LocationsSensor

  • init(config:LocationsSensor.Config?) : Initializes the locations sensor with the optional configuration.
  • start(): Starts the locations sensor with the optional configuration.
  • stop(): Stops the service.

LocationsSensor.Config

Class to hold the configuration of the sensor.

Fields

  • sensorObserver: LocationsObserver? Callback for live data updates. (default = null)
  • frequency: Int how frequent to check the location, in seconds. By default, every 180 seconds. Setting to 0 (zero) will keep the GPS location tracking always on. (default = 180)
  • accuracy: Int the minimum acceptable accuracy of GPS location, in meters. By default, 150 meters. Setting to 0 (zero) will keep the GPS location tracking always on. (default = 150)
  • expirationTime: Int64 the amount of elapsed time, in seconds, until the location is considered outdated. By default, 300 seconds. (default = 300)
  • saveAll: Boolean Whether to save all the location updates or not. (default = false)
  • enabled: Boolean Sensor is enabled or not. (default = false)
  • debug: Boolean enable/disable logging to Logcat. (default = false)
  • label: String Label for the data. (default = "")
  • deviceId: String Id of the device that will be associated with the events and the sensor. (default = "")
  • dbEncryptionKey Encryption key for the database. (default = null)
  • dbType: Engine Which db engine to use for saving data. (default = Engine.DatabaseType.NONE)
  • dbPath: String Path of the database. (default = "aware_locations")
  • dbHost: String Host for syncing the database. (default = null)

Broadcasts

Fired Broadcasts

  • LocationsSensor.ACTION_AWARE_LOCATIONS fired when new location available.
  • LocationsSensor.ACTION_AWARE_GPS_LOCATION_ENABLED fired when GPS location is active.
  • LocationsSensor.ACTION_AWARE_GPS_LOCATION_DISABLED fired when GPS location disabled.

Received Broadcasts

  • LocationsSensor.ACTION_AWARE_LOCATIONS_START: received broadcast to start the sensor.
  • LocationsSensor.ACTION_AWARE_LOCATIONS_STOP: received broadcast to stop the sensor.
  • LocationsSensor.ACTION_AWARE_LOCATIONS_SYNC: received broadcast to send sync attempt to the host.
  • LocationsSensor.ACTION_AWARE_LOCATIONS_SET_LABEL: received broadcast to set the data label. Label is expected in the LocationsSensor.EXTRA_LABEL field of the intent extras.

Data Representations

Locations Data

Contains the locations profiles.

Field Type Description
latitude Double The latitude in degrees.
longitude Double The longitude in degrees.
course Double The direction in which the device is traveling, measured in degrees and relative to due north.
speed Float The instantaneous speed of the device, measured in meters per second.
altitude Double The altitude, measured in meters.
floor Double? The logical floor of the building in which the user is located.
horizontalAccuracy Double The radius of uncertainty for the location, measured in meters.
verticalAccuracy Double The accuracy of the altitude value, measured in meters.
deviceId String AWARE device UUID
label String Customizable label. Useful for data calibration or traceability
timestamp Long Unixtime milliseconds since 1970
timezone Int Rimezone of the device
os String Operating system of the device (e.g., ios)

Example usage

// To initialize the sensor
let locationSensor = LocationsSensor.init(LocationsSensor.Config().apply{config in
    config.sensorObserver = Observer()
    config.debug = true
    config.dbType = DatabaseType.REALM
    // more configuration...
})
// To start the sensor
locationSensor?.start()

// To stop the sensor
locationSensor?.stop()
class Observer:LocationsObserver {
    func onLocationChanged(data: LocationsData) {
    // your code here
    }
}
