Android Decode eNB & cell id from ci

TelephonyManager tm = (TelephonyManage) Context.getSystemService(Context.TELEPHONY_SERVICE)
List<CellInfo> mCellInfo = tm.getALLCellInfo();
CellIdentityLte cellid = cellInfo.getCellIdentity();
String cellidHex = DecToHex(cellid.getCi());
String eNBHex = cellidHex.substring(0, cellidHex.length() - 2);
String lcidHex = cellidHex.substring(cellidHex.length() - 2);
int eNB = HexToDec(eNBHex);
int localCellid = exToDec(lcidHex);


// Decimal -> hexadecimal
 public String DecToHex(int dec){
    return String.format("%x", dec);
}

// hex -> decimal
public int HexToDec(String hex){
    return Integer.parseInt(hex, 16);
}

Android Get LTE signal strength

Use PhoneStateListener:

PhoneStateListener _psl = new PhoneStateListener() {
    public void onSignalStrengthsChanged(SignalStrength signalStrength) {
        Log.v("DEBUG_JOB", "onSignalStrengthsChanged");
        getLteDbm(signalStrength);
    }
};
TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(_psl, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);

There are three methods that I found:

First: When Build.VERSION.SDK_INT  >= 17, use getAllCellInfo() methods of TelephonyManager class. But on some mobile device, getAllCellInfo() always return null.

public int getLteDbm(SignalStrength signalStrength) {
    int rsrp = 0;
    TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
    List<CellInfo> mCellInfo = telephonyManager.getAllCellInfo();
    if (mCellInfo != null && mCellInfo.size() != 0) {
        int index = 0;
        for (CellInfo cellInfo : mCellInfo) {
            if (cellInfo.isRegistered() && cellInfo instanceof CellInfoLte) {
                Log.v("DEBUG_JOB", "[" + index + "]==CellInfoLte");
                CellInfoLte x = (CellInfoLte) cellInfo;
                CellSignalStrengthLte cstr = x.getCellSignalStrength();
                if (cstr != null) {
                    rsrp = cstr.getDbm();
                    Log.v("DEBUG_JOB", "RSRP=" + rsrp);
                }
                CellIdentityLte cellid = x.getCellIdentity();
                int pci = cellid.getPci();
                Log.v("DEBUG_JOB", "PCI=" + pci);
                Log.v("DEBUG_JOB", "CI=" + cellid.getCi());
            }
            index++;
        }
    }
    return  rsrp;
}

======================================================================
Second: Use split string on SignalStrength to get mLteRsrp value. But different mobile device got different position of mLteRsrp value.

public int getLteDbm(SignalStrength signalStrength) {
    String ssignal = signalStrength.toString();
    String[] parts = ssignal.split(" ");
    int rsrp = parts.length >= 9 ? Integer.parseInt(parts[9]) : -1; // some devices is 11
    return rsrp;
}

======================================================================
Last: Use the hidden getLteRsrp() method of the SignalStrength class.

public int getLteDbm(SignalStrength signalStrength) {
    int rsrp = 0;
    try {
        rsrp = (Integer) signalStrength.getClass().getMethod("getLteRsrp").invoke(signalStrength);
    } catch (Exception ex) {
        Log.v("Error", "getLteDbm=" + ex.getMessage());
    }
    return rsrp;
}

Python2.5 Query ArcGIS point feature class, Read and Write csv

import csv
import datetime
import arcgisscripting

C# Debug an ASP Project with Visual Studio 2003

When I try to debug the project, it always say "Unable to find project on the web server. Unable to set server into correct debugging state.".

In order to debug the ASP project, I have to change the following setting:

• In VS 2003:

  
  -------------
     Project - properties
        Configuration Properties
           Debugging
              - Enable ASP Debugging
              - Enable ASP.NET Debugging
  

• In the IIS:

  
  ----------------------
     Default Website - Properties
        Home Directory Tab
           Application Settings - Configuration Button
              Debugging Tab
                 - Enable ASP server-side script debugging
  
     Website (the project you want to debug) - Properties
        Directory tab
           Application Settings - Create Button
  

  This sets an application name for the Website and changes the icon from a default folder icon to a Website icon.
• Add IIS process account to Debugger Users group:

  
  ---------------------------------------------------
     In Computer Management:
        System Tools
           Local Users and Groups
              Groups
                 Debugger Users - properties
                    Add user IWAM_machine-name (the "Launch IIS process account")
  

• Now, to debug in VS 2003:

  
  ------------------------
     right-click the .asp page that the application should start from
        select "Set as Start Page"
