I'm currently using this URL to get my results restricted within Australia:
But I'd like to say limit my searches to the current state let's say New South Wales.
But it's returning the same number of results with items from Victoria, which is not from NSW.
According to the docs:
https://developers.google.com/places/web-service/autocomplete
It does not indicate restricting the state though.
My solution is filter the incoming result by comparing the state and the country with description being returned from Places API. Sample implementation is below:
JSONObject jsonObj = new JSONObject(jsonResults.toString());
JSONArray predsJsonArray = jsonObj.getJSONArray("predictions");
// Extract the Place descriptions from the results
resultList = new ArrayList<>(predsJsonArray.length());
for (int i = 0; i < predsJsonArray.length(); i++) {
if(predsJsonArray.getJSONObject(i) != null){
String description = predsJsonArray.getJSONObject(i).getString("description");
if(description != null){
if(description.contains(state + ", " + country))
resultList.add(new Place(description,
predsJsonArray.getJSONObject(i).getString("place_id")));
}
}
}
I was facing the same problem and ended up building a solution in javascript, capable to restrict an address for whatever you want.
The real thing is that Google API autocompletes methods don't give us a complete restrict address options, only for desired country and for bounds (if you have the coordinates).
And it still a little tricky for users type all the complete address (neighborhood, city, state, etc.) every time he needs to get a correct address, at least in my case of use (firefighters emergency calls attendance).
It's not 100% that it wont return undesirable results, but it will save a lot off users typing efforts.
Basically this script tricks Google APIs and users by adding behind the scenes the necessary restrictions within the request, before it goes to google servers.
It uses service.getPlacePredictions and google.maps.places.AutocompleteService and was implemented in a way that the billing stands for "Autocomplete without Places Details - Per Session", that means you'll be billed only once since when user start typing, till he clicks on an address prediction (the cheaper option available).
Another advantage of using a custom autocomplete, instead the google default widget, is that it won't block the text input if there's a problem with the API Key, like out of limits. So user can type the address and in future the system adms can give the correct treatment to the unverified address.
It's required that Places API and Maps JavaScript API is activated on your console.cloud.google.com.
Well, below is all you'll need to do to use the component.

<p>This example uses service.getPlacePredictions and google.maps.places.AutocompleteService what means that the billing stands for "Autocomplete without Places Details - Per Session"</p>
