Google Places API Code Example in Android

Note: Full Source code can be downloaded at the end of this page

Place Search Using Google Places API

The Google Places API allows you to query for place information on a variety of categories, such as: establishments, prominent points of interest, geographic locations, and much more. You can search for places either by proximity or a text string. A Place Search returns a list of Places along with summary information about each Place; If you want to view additional information it is extracted using Place Details query.

An HTTP URL is used for search query specifying the type of Place you are searching, latitude and longitude of your location and radius.

The HTTP URL should look like:

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=YourAPIKey

Mandatory parameters

key — Your application's API key. This key identifies your application for purposes of quota management and so that Places added from your application are made immediately available to your app. Visit the APIs Console to create an API Project and obtain your key.

location — The latitude/longitude around which to retrieve Place information. This must be specified as latitude,longitude.

radius — Defines the distance (in meters) within which to return Place results. The maximum allowed radius is 50 000 meters. Note that radius must not be included if rankby=distance (described under Optional parameters below) is specified.

 sensor — Indicates whether or not the Place request came from a device using a location sensor (e.g. a GPS) to determine the location sent in this request. This value must be either true or false.
 

A JSON response contains up to four root elements:

status: contains metadata on the request. See Status Codes below.

results: contains an array of Places, with information about each. See Nearby Search Results for information about these results. The Places API returns up to 20 establishment results per query. Additionally, political results may be returned which serve to identify the area of the request.
  
html_attributions: contain a set of attributions about this listing which must be displayed to the user.
  
next_page_token: contains a token that can be used to return up to 20 additional results. A next_page_token will not be returned if there are no additional results to display. The maximum number of results that can be returned is 60. There is a short delay between when a next_page_token is issued, and when it will become valid.

Status Codes

The status field within the search response object contains the status of the request, and may contain debugging information to help you track down why the request failed. The status field may contain the following values:
   
OK indicates that no errors occurred; the place was successfully detected and at least one result was returned.   

ZERO_RESULTS indicates that the search was successful but returned no results. This may occur if the search was passed a latlng in a remote location. 
  
OVER_QUERY_LIMIT indicates that you are over your quota.    

REQUEST_DENIED indicates that your request was denied, generally because of lack of a sensor parameter.   

INVALID_REQUEST generally indicates that a required query parameter (location or radius) is missing.

Place Detail Search

Once you have a reference from a Place Search, you can request more details about a particular establishment or point of interest by initiating a Place Details request. A Place Details request returns more comprehensive information about the indicated place such as its complete address, phone number, user rating and reviews.

A Place Details request is an HTTP URL of the following form:
 
https://maps.googleapis.com/maps/api/place/details/json?reference=ReferenceToPlace&
sensor=true&key=AddYourOwnKeyHere

Adding Your Own new Place using Google Places API

Using Google Places API one can add their own new place to map for which the HTTP URL should look like:

POST https://maps.googleapis.com/maps/api/place/add/json?sensor=true_or_false&key=AddYourOwnKeyHere HTTP/1.1
Host: maps.googleapis.com{
 
"location": {
   
"lat": -33.8669710,
   
"lng": 151.1958750
 
},
 
"accuracy": 50,
 
"name": "Google Shoes!",
 
"types": ["shoe_store"],
 
"language": "en-AU"

}

Deleting a Place

 A Place can only be deleted if:
   
  • It was added by the same application as is requesting its deletion.
  • It has not successfully passed through the Google Maps moderation process, and and is therefore not visible to all applications.

Attempting to delete a Place that does not meet these criteria will return a REQUEST_DENIED status code.

A Place Report delete request is an HTTP POST request of the following form:

POST https://maps.googleapis.com/maps/api/place/delete/json?sensor=true_or_false 
&key=AddYourOwnKeyHere HTTP/1.1
Host: maps.googleapis.com
{
  "reference": "place_reference"
}

Now call PlaceRequest.java from PlaceAdd.java to add you actual location 
into Google Map.

PlaceAdd.java


public class PlaceAdd extends Activity{

 static String formtd_phone_number;

      dialog.setCancelable(false);
      
      final EditText name = (EditText) dialog.findViewById(R.id.place_title);

   }
   //setProgressBarIndeterminateVisibility(false);
   progressDialog.dismiss();
   finish();
     }
    } // End of class SearchSrv here   

} 
 
Now call PlaceRequest.java from ShowPlaceDetail.java to view Place detail

public class ShowPlaceDetail extends Activity {
