Google Places JSON Throws a Parsing Error in Android
I'm writing an android app that takes your current location and returns a list of the stores near you using the Google Places web service. I'm able to get back (what I think is) valid JSON, but when I go to parse the JSON using the Android JSONObject library, I get a开发者_如何学C parsing error.
Here is my class:
public class StoresNearMe {
private String result = "";
private String googleAPIKey = "Omitted for this example";
private String searchRadius = "50";
private Location myLocation;
final String TAG = getClass().getSimpleName();
public StoresNearMe(Location location){
myLocation = location;
}//StoresNearMe
public String getStoresNearMe(){
String result = "Nothing";
result = callGoogleWebService(buildURLForGooglePlaces(myLocation));
convertJSONtoArray(result);
return result;
}//getStoresNearMe
private String callGoogleWebService(String url){
HttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
//request.addHeader("deviceId", deviceId);
ResponseHandler<String> handler = new BasicResponseHandler();
try {
result = httpclient.execute(request, handler);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
httpclient.getConnectionManager().shutdown();
return result;
}//callWebService
private String buildURLForGooglePlaces(Location location){
String baseUrl = "https://maps.googleapis.com/maps/api/place/search/json?";
String lat = String.valueOf(location.getLatitude());
String lon = String.valueOf(location.getLongitude());
String url = baseUrl + "location=" + lat + "," + lon + "&" +
"radius=" + searchRadius + "&" + "sensor=false" +
"&" + "key=" + googleAPIKey;
Log.d(TAG,url);
return url;
}//buildURLForGooglePlaces
private void convertJSONtoArray(String rawJSON){
try {
JSONObject completeJSONObj = new JSONObject(rawJSON);
String json = completeJSONObj.toString();
Log.d(TAG,json);
JSONObject results = completeJSONObj.getJSONObject("results");
} catch (JSONException e) {
Log.d(TAG,"JSON parsing error - fix it:" + e.getMessage());
}
}//convertJSONtoArray
}//StoresNearMe
Here is the JSON returned by my call:

Any help is appreciated - I'm not sure what is going wrong.
Thanks!
The problem is that you're trying to read an array in as an object.
Change
JSONObject results = completeJSONObj.getJSONObject("results");
to
JSONArray results = completeJSONObj.getJSONArray("results");
and the parse exception goes away.
your JSON should be Valid : example :
{\"key\":\"value\" }
