How to get 20+ result from Google Places API?

As per the documentation:

https://developers.google.com/places/web-service/search#PlaceSearchResponses

EDIT: Place API now supports pagination of up to 60 results. See below for details.

The Places API will return up to 20 establishments per query; however, each search can return as many as 60 results, split across three pages. If your search will return more than 20, then the search response will include an additional parameter — next_page_token. Pass the value of next_page_token to the page_token parameter of a new place search to see the next set of 20 results.

There is also strict terms of service that specify you cant Pre-Fetch, Cache, or Store Content unless it is the content identifier or key you are permitted to store i.e. reference token from a places search:

In regards to not being able to find ATM's in India. All places are categorized under the type establishment until Google has enough metadata about a place to categorize it under more specific place types like ATM, cafe, bar etc. A work around that may find more results is to use the keyword parameter in your request with something like 'ATM', 'bank' or 'finance' as the value. As per the documentation:

https://developers.google.com/places/web-service/search#PlaceSearchRequests

The keyword parameter is matched against all available fields, including but not limited to name, type, and address, as well as customer reviews and other third-party content.

You can do this by using Google API JAVA Client - Here is an example using the java client for getting all the 60 results.

public PlacesList search(double latitude, double longitude, double radius, String types)
            throws Exception {

        try {

            HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
            HttpRequest request = httpRequestFactory
                    .buildGetRequest(new GenericUrl("https://maps.googleapis.com/maps/api/place/search/json?"));
            request.getUrl().put("key", YOUR_API_KEY);
            request.getUrl().put("location", latitude + "," + longitude);
            request.getUrl().put("radius", radius); 
            request.getUrl().put("sensor", "false");
            request.getUrl().put("types", types);

            PlacesList list = request.execute().parseAs(PlacesList.class);

            if(list.next_page_token!=null || list.next_page_token!=""){
                         Thread.sleep(4000);
                         /*Since the token can be used after a short time it has been  generated*/
                request.getUrl().put("pagetoken",list.next_page_token);
                PlacesList temp = request.execute().parseAs(PlacesList.class);
                list.results.addAll(temp.results);

                if(temp.next_page_token!=null||temp.next_page_token!=""){
                    Thread.sleep(4000);
                    request.getUrl().put("pagetoken",temp.next_page_token);
                    PlacesList tempList =  request.execute().parseAs(PlacesList.class);
                    list.results.addAll(tempList.results);
              }

            }
            return list;

        } catch (HttpResponseException e) {
            return null;
        }

    }

Google API fetches the 20 Result in one page suppose you want to use the next page 20 result then we use the next_page_token from google first page xml as a result.

1) https://maps.googleapis.com/maps/api/place/search/xml?location=Enter latitude,Enter Longitude&radius=10000&types=store&hasNextPage=true&nextPage()=true&sensor=false&key=Enter Google_Map_key

in second step you use the first page's next_page_token data

2)https://maps.googleapis.com/maps/api/place/search/xml?location=Enter Latitude,Enter Longitude&radius=10000&types=store&hasNextPage=true&nextPage()=true&sensor=false&key=enter google_map_key &pagetoken="Enter the first page token Value"
