Google warns us about PlaceID changes and suggests;
Place IDs may change due to large-scale updates on the Google Maps database. In such cases, a place may receive a new place ID, and the old ID returns a NOT_FOUND response.
You can refresh Place IDs free of charge, by making a Place Details request, specifying only the ID field in the fields parameter.
Unfortunately, there is no sample code for Java/Kotlin on their website except a link to their web services
String placeID ="Some place ID";
List<Place.Field> placeFields = Arrays.asList(
Place.Field.ID,
);
// Construct a request object, passing the place ID and fields array.
FetchPlaceRequest request = FetchPlaceRequest.builder(placeID, placeFields).build();
placesClient.fetchPlace(request).addOnSuccessListener((response) -> {
Place place = response.getPlace();
if (!placeID.equals(place.getId())) {
//update your old placeID
}
}).addOnFailureListener((exception) -> {
if (exception instanceof ApiException) {
//Place removed.
}
});
Is this a porper way to update a placeIDs with Java?
I've tested my databases and found a case where the update occurs. The below code contains both a renewed placeID, removed placeID, and still valid palceID so that one can test.
ArrayList<String> placeIDsList = new ArrayList<>();
placeIDsList.add("ChIJTaKjynxesBQREvi1CU5QUFg");
placeIDsList.add("EjhDdW1odXJpeWV0IE1haGFsbGVzaSwgVXp1biBTay4sIEV6aW5lL8OHYW5ha2thbGUsIFR1cmtleSIuKiwKFAoSCakQkmN8XrAUEVkLpNK_F4IJEhQKEgmFzKyYe16wFBGSjU7F2ooIIg");
placeIDsList.add("hIJy9YVxdxpsBQRq0-xUVJdZQ8");
// Specify the fields to return (in this example all fields are returned).
List<Place.Field> placeFields = Arrays.asList(Place.Field.ID);
for (String plc : placeIDsList ) {
// Construct a request object, passing the place ID and fields array.
FetchPlaceRequest request = FetchPlaceRequest.builder(plc, placeFields).build();
Log.e(TAG,"request for place with ID = " + plc);
placesClient.fetchPlace(request).addOnSuccessListener((response) -> {
Place place = response.getPlace();
if (!plc.equals(place.getId())) {
Log.e(TAG,"placeID renewed");
Log.e(TAG,"placeID old = " + plc);
Log.e(TAG,"placeID new = " + place.getId());
} else {
Log.e(TAG, "Place found: " + place.getId());
}
}).addOnFailureListener((exception) -> {
if (exception instanceof ApiException) {
ApiException apiException = (ApiException) exception;
int statusCode = apiException.getStatusCode();
// Handle error with given status code.
Log.e(TAG, "Place with ID "+plc+" not found");
Log.e(TAG, "Exception message is :" + exception.getMessage());
Log.e(TAG, "Status code = " + statusCode);
}
});
}
The output is
E/MapsActivity: request for place with ID = ChIJTaKjynxesBQREvi1CU5QUFg
E/MapsActivity: request for place with ID = jhDdW1odXJpeWV0IE1haGFsbGVzaSwgVXp1biBTay4sIEV6aW5lL8OHYW5ha2thbGUsIFR1cmtleSIuKiwKFAoSCakQkmN8XrAUEVkLpNK_F4IJEhQKEgmFzKyYe16wFBGSjU7F2ooIIg

E/MapsActivity: Place with ID hIJy9YVxdxpsBQRq0-xUVJdZQ8 not found
E/MapsActivity: Exception message is :9012: INVALID_REQUEST
E/MapsActivity: Status code = 9012
E/MapsActivity: Place found: ChIJTaKjynxesBQREvi1CU5QUFg
And it seems that the status code 9102
is for place not found.
