how to get LTE cell location in android?

Question

I see that we have classes for CDMACellLocation and GSMCellLocation, but there is nothing specific for LTE. Can can I get the LTE cell location specific to my telephony service context? Thanks!

Answer 1

you could take info from LTE connection, with a specific cast on instances belonging to CellInfo's list.

MobileInfoRecognizer mobileInfoRecognizer = new MobileInfoRecognizer();
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
List<CellInfo> cellInfos = tm.getAllCellInfo();
additional_info = mobileInfoRecognizer.getCellInfo(cellInfos.get(0));

In my application I noticed that you can take only the first element in your list; I show you my custom class:

public class MobileInfoRecognizer {
    public String getCellInfo(CellInfo cellInfo) {
            String additional_info;
            if (cellInfo instanceof CellInfoGsm) {
                CellInfoGsm cellInfoGsm = (CellInfoGsm) cellInfo;
                CellIdentityGsm cellIdentityGsm = cellInfoGsm.getCellIdentity();
                additional_info = "cell identity " + cellIdentityGsm.getCid() + "\n"
                        + "Mobile country code " + cellIdentityGsm.getMcc() + "\n"
                        + "Mobile network code " + cellIdentityGsm.getMnc() + "\n"
                        + "local area " + cellIdentityGsm.getLac() + "\n";
            } else if (cellInfo instanceof CellInfoLte) {
                CellInfoLte cellInfoLte = (CellInfoLte) cellInfo;
                CellIdentityLte cellIdentityLte = cellInfoLte.getCellIdentity();
                additional_info = "cell identity " + cellIdentityLte.getCi() + "\n"
                        + "Mobile country code " + cellIdentityLte.getMcc() + "\n"
                        + "Mobile network code " + cellIdentityLte.getMnc() + "\n"
                        + "physical cell " + cellIdentityLte.getPci() + "\n"
                        + "Tracking area code " + cellIdentityLte.getTac() + "\n";
            } else if (cellInfo instanceof CellInfoWcdma){
                CellInfoWcdma cellInfoWcdma = (CellInfoWcdma) cellInfo;
                CellIdentityWcdma cellIdentityWcdma = cellInfoWcdma.getCellIdentity();
                additional_info = "cell identity " + cellIdentityWcdma.getCid() + "\n"
                        + "Mobile country code " + cellIdentityWcdma.getMcc() + "\n"
                        + "Mobile network code " + cellIdentityWcdma.getMnc() + "\n"
                        + "local area " + cellIdentityWcdma.getLac() + "\n";
            }
            return additional_info;
    }
}

So, if device under test doesn't support LTE, you can always obtain other related information about its connection. Hope you can find it useful.
