How to Know Location Area Code and Cell Id in Android Phone

How to get Cell ID and Location Area code in android 9 ( Pie ) devices without using GPS?

Telephony information now relies on device location setting

If the user has disabled device location on a device running Android 9, the following methods don't provide results:

getAllCellInfo()
listen()
getCellLocation()
getNeighboringCellInfo()

Android : Finding location using LAC and CID

This one way to get location through LAC and CID:

        TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    GsmCellLocation cellLocation = (GsmCellLocation) telephonyManager.getCellLocation();

    int cid = cellLocation.getCid();
    int lac = cellLocation.getLac();
    textGsmCellLocation.setText(cellLocation.toString());
    textCID.setText("gsm cell id: " + String.valueOf(cid));
    textLAC.setText("gsm location area code: " + String.valueOf(lac));

    if(RqsLocation(cid, lac)){
     textGeo.setText(
          String.valueOf((float)myLatitude/1000000)
          + " : "
          + String.valueOf((float)myLongitude/1000000));
    latitude=String.valueOf((float)myLatitude/1000000);
     longitude=String.valueOf((float)myLongitude/1000000);
     lat_double=Double.parseDouble(latitude);
     lang_double=Double.parseDouble(longitude);
     geocoder = new Geocoder(AndroidTelephonyManager.this, Locale.ENGLISH);
        try {
            addresses = geocoder.getFromLocation(lat_double,  lang_double, 1);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        StringBuilder str = new StringBuilder();
        //if (geocoder.isPresent()) {
            // Toast.makeText(getApplicationContext(),
            // "geocoder present",
            // Toast.LENGTH_SHORT).show();
            Address returnAddress = addresses.get(0);

            String area = returnAddress.getFeatureName();
            String thfare = returnAddress.getThoroughfare();
            String localityString = returnAddress.getLocality();
            // String region_code = returnAddress.getCountryCode();
            String zipcode = returnAddress.getPostalCode();
            String state = returnAddress.getAdminArea();
            String sublocal = returnAddress.getSubLocality();
            String city = returnAddress.getCountryName();
     Toast.makeText(getApplicationContext(),  latitude, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), longitude, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), thfare, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), area, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), localityString, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), zipcode, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), sublocal, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), state, Toast.LENGTH_LONG).show();
     Toast.makeText(getApplicationContext(), city, Toast.LENGTH_LONG).show();
    }else{
     textGeo.setText("Can't find Location!");
    };
   // }
}


private Boolean RqsLocation(int cid, int lac){

       Boolean result = false;

       String urlmmap = "http://www.google.com/glm/mmap";

          try {
           URL url = new URL(urlmmap);
              URLConnection conn = url.openConnection();
              HttpURLConnection httpConn = (HttpURLConnection) conn;      
              httpConn.setRequestMethod("POST");
              httpConn.setDoOutput(true);
              httpConn.setDoInput(true);
      httpConn.connect();

      OutputStream outputStream = httpConn.getOutputStream();
            WriteData(outputStream, cid, lac);

            InputStream inputStream = httpConn.getInputStream();
            DataInputStream dataInputStream = new DataInputStream(inputStream);

            dataInputStream.readShort();
            dataInputStream.readByte();
            int code = dataInputStream.readInt();
            if (code == 0) {
             myLatitude = dataInputStream.readInt();
             myLongitude = dataInputStream.readInt();

                result = true;

            }
     } catch (IOException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }

     return result;

      }

private void WriteData(OutputStream out, int cid, int lac)
          throws IOException          
{    
    DataOutputStream dataOutputStream = new DataOutputStream(out);
    dataOutputStream.writeShort(21);
    dataOutputStream.writeLong(0);
    dataOutputStream.writeUTF("en");
    dataOutputStream.writeUTF("Android");
    dataOutputStream.writeUTF("1.0");
    dataOutputStream.writeUTF("Web");
    dataOutputStream.writeByte(27);
    dataOutputStream.writeInt(0);
    dataOutputStream.writeInt(0);
    dataOutputStream.writeInt(3);
    dataOutputStream.writeUTF("");

    dataOutputStream.writeInt(cid);
    dataOutputStream.writeInt(lac);   

    dataOutputStream.writeInt(0);
    dataOutputStream.writeInt(0);
    dataOutputStream.writeInt(0);
    dataOutputStream.writeInt(0);
    dataOutputStream.flush();       
}

}

How to find GSM Location area code and Cell Id for iPhone

You can't find the LAC and Cell Id, but you can find the approximate location using CoreLocation. You can then use this to get an approximate area code if you have a suitable mapping of geo-locations to area codes; but it's unlikely that you'll be able to find a perfect mapping in any case, even if you knew the Cell Id.

The documentation for Core Location is here:

http://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CoreLocation_Framework/

How to find short cell ID?

It appears that "short cell ID" is nothing but the lower 16 bits of the Long cell ID.

So I used:

int cid = cl.getCid();
short cid_short = (short) cid;
