Hi, I have a strange behavior using the webviewextra2.2 library with a web page that has a simple geolocation function.
In practice the coordinates are read only once instead of being updated regularly. Obviously if I access the page directly with a browser everything works. I pass you the code that I used to do the tests:

geolocalizzazione:
$(document).ready(function(){
let watchId;
startTracking();
function startTracking()
{
if ("geolocation" in navigator) {
watchId = navigator.geolocation.watchPosition(
(position) => {
//alert('ss');
latitudine = position.coords.latitude;
longitudine = position.coords.longitude;
$('#lat').text(latitudine);
$('#long').text(longitudine);
},
(error) => {
console.log("Errore durante il tracking:", error.message);
},
{
enableHighAccuracy: true, // Usa il GPS per maggiore precisione
maximumAge: 0, // Non usa dati memorizzati
timeout: 10000 // Timeout massimo per ottenere la posizione
}
);
} else {
console.error("Il browser non supporta la geolocalizzazione.");
}
}
});
