谁能告诉我如何在android中使用google places api。我正在eclipse中开发这个应用程序，我需要找到我所在地区附近最近的加油站和车库。我浏览了许多网站。我没有找到正确的答案。我需要一个示例代码，因为我是 json 概念的新手。
public class place {
private static final String PLACES_SEARCH_URL = "https://maps.googleapis.com/maps/api/place/search/json?";
private static final boolean PRINT_AS_STRING = false;
public void performSearch() throws Exception {
try {
System.out.println("Perform Search ....");
System.out.println("-------------------");
HttpRequestFactory httpRequestFactory = createRequestFactory(transport);
HttpRequest request = httpRequestFactory.buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
request.url.put("key", "api key");
request.url.put("location", lat + "," + lng);
request.url.put("radius", 500);
request.url.put("sensor", "false");
if (PRINT_AS_STRING) {
System.out.println(request.execute().parseAsString());
} else {
PlacesList places = request.execute().parseAs(PlacesList.class);
System.out.println("STATUS = " + places.status);
for (Place place : places.results) {
System.out.println(place);
}
}
} catch (HttpResponseException e) {
System.err.println(e.response.parseAsString());
throw e;
}
