hi

I want to check whether my device is connected to internert or not ? in order to do that i have use RadioInfo, WLANInfo, CoverageInfo classes... and use dialog box which tells user conncted or not.

it works as per the connection when i first load the simulator....

if i close all the connection from my manage connection it tells me not connected.....

if i enable only WLAN it i get it is connected but it is unable to make any connection to internet.

if i enable only EDGE it i get it is connected but it is unable to make any connection to internet.

if i reload the simulator and try to run same it works well. but once i change any connection to on or off i cant make any connection to internet.

please help me out its relly urgent please please

What simulator version are you running and which OS are you targeting (i.e. 4.5, 4.7, 5.0, etc)?

what do you mean by "it is connected but is unable to make any connection to internet"?

You can check it by :

 if((CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_MDS)) || (CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_BIS_B)) != false)

{

System.out.printls("Internet  available");

}

else

{

{

System.out.printls("Not  available");

}

Try it ..

Hope it works.

Thnx

This did not work for me. Is

RadioInfo.isDataServiceOperational();

suffficient?

I used the function below to check if internet is not available, available through wifi or available through Mobile Network. For each I append the appropriate text so that if it finds wifi connectivity, It appends string to connect through wifi etc

import net.rim.device.api.system.CoverageInfo;

import net.rim.device.api.system.DeviceInfo;

import net.rim.device.api.system.WLANInfo;

private static String getConnectionString()

      {

            String value="";

            if(CoverageInfo.isOutOfCoverage())

                  {

                        Dialog.alert("No Internet Coverage. Enable Internet And Try Again");                       

//                      return "";

                  }                

            else if(WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)

            {

                  Dialog.alert("Wireless Found");

                  value="interface=wifi";

//                return "";

            }

            else if(CoverageInfo.getCoverageStatus() ==  CoverageInfo.COVERAGE_DIRECT )

            {

                  Dialog.alert("Coverage Direct");

                  value="deviceside=true";

//                return "";

            }

            return value;

      }
