Get Base Station Information

This topic guild how to get the sdcard information about the base station.

In BaseStationInfoHelper.java

package com.main;

import android.content.Context;
import android.telephony.CellLocation;
import android.telephony.TelephonyManager;
import android.telephony.cdma.CdmaCellLocation;
import android.telephony.gsm.GsmCellLocation;

public class BaseStationInfoHelper {
 //android.permission.ACCESS_COARSE_LOCATION
 public static class BaseStationInfo {
        /** Country */
        public int mcc = -1;
        /** ISP */
        public int mnc = -1;
        /** Base Station Number*/
        public int lac = -1;
        /** Small Region Number */
        public int cid = -1;
    }
    public static BaseStationInfo getSimCardInfo(Context context) {
        final TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

        BaseStationInfo res = new BaseStationInfo();

        CellLocation clll = telephony.getCellLocation();
        if (clll == null) {
            return res;
        }

        if (clll instanceof GsmCellLocation) {
            GsmCellLocation gsm = (GsmCellLocation) clll;
            int lac = gsm.getLac();
            String mcc = telephony.getNetworkOperator().substring(0, 3);
            String mnc = telephony.getNetworkOperator().substring(3);

            res.cid = gsm.getCid();
            res.mcc = Integer.parseInt(mcc);
            res.mnc = Integer.parseInt(mnc);
            res.lac = lac;
        } else if (clll instanceof CdmaCellLocation) {
            CdmaCellLocation cdma = (CdmaCellLocation) clll;
            int lac = cdma.getNetworkId();
            String mcc = telephony.getNetworkOperator().substring(0, 3);
            String mnc = telephony.getNetworkOperator().substring(3);
            int cid = cdma.getBaseStationId();
            res.cid = cid;
            res.mcc = Integer.parseInt(mcc);
            res.mnc = Integer.parseInt(mnc);
            res.lac = lac;
        }
        return res;
    }
}

In MainActivity.java

package com.main;
import com.example.celllocation.R;
import com.main.BaseStationInfoHelper.BaseStationInfo;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;


public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  //
  TextView tv = (TextView) this.findViewById(R.id.textView1);
  //
  BaseStationInfo info = BaseStationInfoHelper.getSimCardInfo(this);
  String displayString = "";
  if(info != null){
   displayString += "Country mcc = " + info.mcc + "\r\n";
   displayString += "ISP mnc = " + info.mnc + "\r\n";
   displayString += "Base Station Number lac = " + info.lac + "\r\n";
   displayString += "Cell id = " + info.cid + "\r\n";
   //
   tv.setText(displayString);
  }
  else{
   tv.setText("Cannot get the base station information.");
  }
 }

}
