Operating mode in iPhone/iPad

When a GPS function is first run, the system requests geolocation permission from the user. If the user refuses, all the GPS functions used in the rest of the application will fail (fatal error).
To re-allow the use of GPS for this application, the system configuration of the application must be modified.

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_LOCATION.
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.
Android 11 specific case: This function requires the ACCESS_BACKGROUND_LOCATION permission to access the device's location.
This permission allows using the function when the application is in the background.
If the application needs to use background location:
  • Manually add the "ACCESS_BACKGROUND_LOCATION" permission in the Android application generation wizard.
  • Explicitly request background location permission with PermissionRequest. For example:
    PermissionRequest(permBackgroundLocation, Callback)
    INTERNAL PROCÉDURE Callback(p is Permission)
    IF p.Granted THEN
    // Functions that require background location access can be used
    END
    END
A window allows users 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.

Remarks:
  • Follow Google's guidelines for applications that require background location access. For more details, see https://support.google.com/googleplay/android-developer/answer/9799150. If these conditions are not met (especially user information requirements), applications may not be accepted for publication on Google Play.
  • The background location permission should only be requested if the location permission has been granted. Otherwise, PermissionRequest will fail.
  • If the option chosen by the user for the background location access request is more restrictive than the option chosen for the location access request, the application will be automatically restarted.
  • On devices running Android 10 or earlier, if location permission has been granted to the application, the background location permission will be granted without displaying a window.
