Browserfield error on Wifi connectivity without Internet connection

Hi,

 

I'm using browserfield in my app to show some site to the user. Before trying to load the html site, I check for connectivity using this code:

 

public static boolean isCoverageSufficent()
	{
		boolean retval = false;
		
		if(RadioInfo.getState() == RadioInfo.STATE_ON)
			if(RadioInfo.getNetworkService() == RadioInfo.NETWORK_SERVICE_EDGE || CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT))
				retval = true;
		if(RadioInfo.getSignalLevel(RadioInfo.WAF_WLAN) != RadioInfo.LEVEL_NO_COVERAGE)
			retval = true;
		return retval;
	}

 

However, in situation where the device is connect to a Wifi which has no Internet connectivity, this method returns true. Consequently the browserfield tries to load the page, fails and instead shows this message:

http://www.mysite.com/<br><br>Could not select proper Transport Descriptor for: http://www.mysite.com/

 where http://www.mysite.com is the page I'm trying to load.

 

What I want to do, is to handle this case, either by detecting it in isCoverageSufficient method or in some BrowserField method (I tried using documentError of BrowserFieldListener, but the flow never reached there), and show appropriate dialog to the user.

 

How can I do it? Any idea? Smiley Sad

The solution given in that thread has same effect.

if(CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT, RadioInfo.WAF_WLAN, false))

It detects that the device is connected to Wifi, but cannot detect whether that Wifi has Internet connectivity or not (ie WLAN without Internet).

If I can detect when BrowserField fails to load the page due to this (some event /error handler of BrowserField), that'll also help.

Thanks.
