Required permissions

Calling this function changes the permissions required by the application.
Required permissions :
  • ACCESS_WIFI_STATE: This permission allows the applications to access information regarding the Wi-Fi networks.
  • ACCESS_FINE_LOCATION: This permission allows the application to access precise device location.
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 PROCEDURE 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.
