http://code.google.com/p/gears/issues/detail?id=1039
Dear all,
I post cell information (CID,LAC,MCC,MNC...) to
https://www.googleapis.com/geolocation/v1/geolocate?key=my_key,but it
always return error 400,can you help me ? Thanks~
1)return error information as follows:
{
"error": {
"errors": [
{
"domain": "global",
"reason": "parseError",
"message": "Parse Error"
}
],
"code": 400,
"message": "Parse Error"
}
}
2)I implement as follows:
public class SCell{
public int MCC;
public int MNC;
public int LAC;
public int CID;
}
private SItude getItude(SCell cell) throws Exception {
SItude itude = new SItude();
/** Using HttpClient of android by default*/
HttpClient client = new DefaultHttpClient();
/** using post'method */
HttpPost post = new
HttpPost("https://www.googleapis.com/geolocation/v1/geolocate?key=XXXXXXXXXXXXXXXXXX";);
try {
/** POST JSON data structure */
JSONObject holder = new JSONObject();
holder.put("homeMobileCountryCode", cell.MCC);
holder.put("homeMobileNetworkCode", cell.MNC);
holder.put("radioType", "gsm");
holder.put("carrier", "cmcc");
JSONObject tower = new JSONObject();
tower.put("cellId", cell.CID);
tower.put("locationAreaCode", cell.LAC);
tower.put("mobileCountryCode", cell.MCC);
tower.put("mobileNetworkCode", cell.MNC);
tower.put("age", 0);
tower.put("signalStrength", -60);
tower.put("timingAdvance", 15);
JSONArray towerarray = new JSONArray();
towerarray.put(tower);
holder.put("cellTowers", towerarray);
StringEntity query = new StringEntity(holder.toString());
post.setEntity(query);
/** send out JSON data,and return data */
HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();
BufferedReader buffReader = new BufferedReader(new
InputStreamReader(entity.getContent()));
StringBuffer strBuff = new StringBuffer();
String result = null;
while ((result = buffReader.readLine()) != null) {
strBuff.append(result);
}
/** parse JSON data to get longitude and latitude */
JSONObject json = new JSONObject(strBuff.toString());
JSONObject subjosn = new JSONObject(json.getString("location"));
itude.latitude = subjosn.getString("latitude");
itude.longitude = subjosn.getString("longitude");
Log.i("Itude", itude.latitude + itude.longitude);
} catch (Exception e) {
Log.e(e.getMessage(), e.toString());
throw new Exception("error info :"+e.getMessage());
} finally{
post.abort();
client = null;
}
return itude;
}
