Example

pos = GPSLastPosition()
IF ErrorOccurred = False THEN
Info(" Latitude: " + pos..Latitude)
Info(" Longitude: " + pos..Longitude)
END

Syntax

<Result> = GPSLastPosition()

<Result>: geoPosition variable

Name of geoPosition variable. This variable contains the information about the last known device position. To find out whether the position failed to be retrieved, use the ErrorOccurred variable.

Remarks

Special cases

To find out whether the ..Speed, ..Precision, ..Direction or ..Altitude properties of a geoPosition variable have been filled when retrieving the position, use ..SpeedValid, ..PrecisionValid, ..DirectionValid and ..AltitudeValid.
To reinitialize a geoPosition variable, use VariableReset.
We advise you to initialize the parameters of location provider with GPSInitParameter before retrieving a position.
The positioning information that was retrieved corresponds to the last known device position: therefore, they may not correspond to the current device position if the device was moved while the GPS signal was not valid for example.
To find out the date and time at which the position was calculated, use the MeasurementDate property of geoPosition variable.
..Speed, ..Precision, ..Direction and ..Altitude will be specified only if the location provider allows it (otherwise, these properties will take their default value). The location provider can be configured by GPSInitParameter.

Required permissions

The call to this function modifies the permissions required by the application.
Required permission: ACCESS_FINE_LOCATION.

Android 10 specific case: Android 10 has implemented a new permission for the functions that allow locating the device: ACCESS_BACKGROUND_PERMISSION.
This permission allows using the function when the application is in the background.
When this permission is added to the application, a window allows the user to:

allow access to the device location while the application is in the background,
allow access to the location only while the application is in use,
deny access to the location.

The user can also change these permissions at any time in the Android settings.
