getGeolocation

Returns the Global Positioning System (GPS) location of a mobile device.

Syntax

ui.Interface.frontCall("mobile", "getGeolocation",
   [], [status, latitude, longitude] )
  1. status - Holds the status of the front call execution.
  2. latitude - Holds the current latitude.
  3. longitude - Holds the current longitude.

Usage

The "getGeolocation" front call returns the current location of the mobile device, based on the current GPS information.

Important: For GMA / Android™, using the getGeolocation front call needs the android.permission.ACCESS_FINE_LOCATION and android.permission.ACCESS_COARSE_LOCATION Dangerous Permissions to be specified when building the APK. See Android permissions for more details.
The possible values returned in the status parameter are:
  • "ok": The mobile device location was found.
  • In case of failure, the status variable contains the error description, for example, "location services not enabled".

It is recommended that the returned coordinates are stored in FLOAT variables.

If the device's location cannot be found within a given period, the front call returns an error status.

     [], [status, latitude, longitude] )
