Hi,

Since the device cannot connect to the Internet fi Data service is set to OFF, not even with WiFI, I need to prompt an Internet Unavailable message when data services are off.

can anyone please tell me how can i do this? 

I have been trying several options, but none worked.

The best advice i got so far is to use a HttpConnection ong google.com. I think it works, but i would like something more...elegant

Regards,

Alex

Have a look into the RadioInfo class

isDataServiceOperational

method may help.

Hi alexpoke

if(CoverageInfo.getCoverageStatus()==CoverageInfo.COVERAGE_NONE)
{
Dialog.alert("No Connection: ");
}
else
{
Dialog.alert("Connection: ");
}

Thanks

H,

You can check like this also,

 if(!checkCoverage() )

{

    Dialog.alert("No Connection.");

}

Hi guys,

Thank you for your replys,

Unfortunately none of the solutions  you suggested worked on the device. However, lakshman9687's approach works well on the Simulator.

I am using a Torch 9860 with 3G and WiFi on and Data Services Off to test this.

Apparently the browser and the App World app seem to notice the missing of the service, so I guess there must be a way..

Thanks again for your feedback.

CHeers, Alex

"Unfortunately none of the solutions you suggested worked on the device."

I assume there must e a solution, but I haven't found it yet

"Unfortunately none of the solutions  you suggested worked on the device"

You mean that they suggested there was data service when there was not or the other way round?  Can you give us the results you saw and the device OS level you tested on?

Hi,

Apparently I was wrong. I don't really know how I tested that and got misleading results, but now I am testing it again on the same device and it appears to be working just fine.

Sorry for this.

To summarize here is the code that works: 

boolean coverage_status = false;
		        
if (CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_MDS)) {
    coverage_status = true;
} else if (CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_BIS_B)) {
    coverage_status = true;
} else if ((RadioInfo.areWAFsSupported(RadioInfo.WAF_WLAN) && WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)) {
    coverage_status = true;
} else if (CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT)) {
    coverage_status = true;
}
		        
return coverage_status;

 Thanks again,  lakshman9687, for the solution.

Cheers,

Alex
