Get city name and postal code from Google Place API on Android

Question

I'm using Google Place API for Android with autocomplete

Everything works fine, but when I get the result as shown here, I don't have the city and postal code information.

    private ResultCallback<PlaceBuffer> mUpdatePlaceDetailsCallback         = new ResultCallback<PlaceBuffer>() {     @Override     public void onResult(PlaceBuffer places) {         if (!places.getStatus().isSuccess()) {             // Request did not complete successfully             Log.e(TAG, "Place query did not complete. Error: " + places.getStatus().toString());              return;         }         // Get the Place object from the buffer.         final Place place = places.get(0);          // Format details of the place for display and show it in a TextView.         mPlaceDetailsText.setText(formatPlaceDetails(getResources(), place.getName(),                 place.getId(), place.getAddress(), place.getPhoneNumber(),                 place.getWebsiteUri()));          Log.i(TAG, "Place details received: " + place.getName());     } }; 

The Place class doesn't contain that information. I can get the full human readable address, the lat and long, etc.

How can I get the city and postal code from the autocomplete result?

Answer 1

You can not normally retrieve city name from the Place,
but you can easily get it in this way:
1) Get coordinates from your Place (or however you get them);
2) Use Geocoder to retrieve city by coordinates.
It can be done like this:

private Geocoder mGeocoder = new Geocoder(getActivity(), Locale.getDefault());  // ...    private String getCityNameByCoordinates(double lat, double lon) throws IOException {       List<Address> addresses = mGeocoder.getFromLocation(lat, lon, 1);      if (addresses != null && addresses.size() > 0) {          return addresses.get(0).getLocality();      }      return null;  }

City name and postal code can be retrieved in 2 steps

1) Making a web-service call to https://maps.googleapis.com/maps/api/place/autocomplete/json?key=API_KEY&input=your_inpur_char. The JSON contains the place_id field which can be used in step 2.

2) Make another web-service call to https://maps.googleapis.com/maps/api/place/details/json?key=API_KEY&placeid=place_id_retrieved_in_step_1. This will return a JSON which contains address_components. Looping through the types to find locality and postal_code can give you the city name and postal code.

Code to achieve it

JSONArray addressComponents = jsonObj.getJSONObject("result").getJSONArray("address_components");         for(int i = 0; i < addressComponents.length(); i++) {             JSONArray typesArray = addressComponents.getJSONObject(i).getJSONArray("types");             for (int j = 0; j < typesArray.length(); j++) {                 if (typesArray.get(j).toString().equalsIgnoreCase("postal_code")) {                     postalCode = addressComponents.getJSONObject(i).getString("long_name");                 }                 if (typesArray.get(j).toString().equalsIgnoreCase("locality")) {                     city = addressComponents.getJSONObject(i).getString("long_name")                 }             }         }
