JSON format Error
I want to pass address and want lat and long . But I got complete String from maps.google.com. But there is error in JSON format.
I try below Code
Error :Couldn't get connection factory client
getLocationInfo("3 cité Nollez Paris France");
public static void getLocationInfo(String address) {
StringBuilder stringBuilder = new StringBuilder();
try {
address = address.replaceAll(" ","%20");
HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false");
HttpClient client = new DefaultHttpClient();
HttpResponse response;
stringBuilder = new StringBuilder();
response = client.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream stream = entity.getContent();
int b;
while ((b = stream.read()) != -1) {
stringBuilder.append((char) b);
}
System.out.print(stringBuilder);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
JSONObject jsonObject = new JSONObject();
try {
jsonObject = new JSONObject(stringBuilder.toString());
longitute = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lng");
System.out.print(longitute);
latitude = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lat");
System.out.print(latitude);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// return jsonObject;
}

Add the following code in your Map activity before super.onCreate()
ExampleActivity:-
public class ExampleActivity extends Activity {
// url to make request
private static String url = "http://maps.googleapis.com/maps/api/geocode/json?address="+address.replace(" ", "%20")+"&sensor=true";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tvlat = (TextView) findViewById(R.id.tvlat);
tvlng = (TextView) findViewById(R.id.tvlng);
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url);
try {
System.out.println("Location Latitude"
+ json.getJSONArray("results").getJSONObject(0)
.getJSONObject("geometry")
.getJSONObject("location").getString("lat"));
System.out.println("Location Longitude"
+ json.getJSONArray("results").getJSONObject(0)
.getJSONObject("geometry")
.getJSONObject("location").getString("lng"));
} catch (JSONException e) {
e.printStackTrace();
}
}
}
JSONPareser:-
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
Then run your app, it worked fine for me.

There is no need to worry if that "couldn't get connection error" while using maps.. it will work fine even after the occurrence of that.. If your code doesnt work then there is other reason. check to it..
