Android手机号获取地理位置

Android手机号获取地理位置信息

Android 通过手机号获取本机所在地理位置信息。

由于手机号通过基站信号传递，所以定位信息在最近基站附近，且有一部分误差。

class

{

public static void main(String[] args)

{

System.out.println("Hello World!");

}

public void test(){

TelephonyManager telMgr =

(TelephonyManager)getSystemService(TELEPHONY_SERVICE);

//生成连接网络

ConnectivityManager connMgr =

(ConnectivityManager)getSystemService(CONNECTIVITY_SERVICE);

//获取基站信息

GsmCellLocation cellLocation =

(GsmCellLocation)telMgr.getCellLocation();

NetworkInfo info = connMgr.getActiveNetworkInfo();

if(info！=null&&info.isConnected()){

int cellId = cellLocation.getCid();

int lac = cellLocation.getLac();

//访问google，获取返回值

String urlStr = "/loc/json";

URL url = new URL(urlStr);

HttpURLConnection conn = (HttpURLConnection)

url.openConnection();

conn.setRequestMethod("POST");

conn.setRequestProperty("Content-Type",

"appplication/json");

conn.setRequestProperty("User-Agent","UNTRUSTED/1.0");

String json = "{"

+ "\"host\":\"\","

+ "\"version\":\"1.1.0\","

+ "\"cell_towers\":[{\"cell_id\":\""

+ cellId + "\",\"location_area_code\":\""

+ lac+ "\"}]}";

conn.setDoOutput(true);

conn.setDoInput(true);

conn.setRequestProperty("Content-Length",

String.valueOf(json.length()));

OutputStream os = conn.getOutputStream();

os.write(json.getBytes());

os.close();

InputStream is = conn.getInputStream();

BufferedReader in = new BufferedReader (new InputStreamReader(is));

result = in.readLine();

in.close();

//整理结果集

int index = result.indexOf("latitude");
