Mobile device detect internet connection. How?

It seems like an on completed Ajax event gets run even when there is no internet connection. Is that right?

I'm trying to make a reliable way to detect internet connection on device and I would have thought the Ajax On Completed request wouldn't trigger without a connection but apparently not.

I am currently at a loss of how to detect internet connection on device. I've spent 2 days on this so far.!?!?

Anyone know the answer? Thanks

Still no luck. I even tried doing this script which works perfectly fine on PC but on device it always returns as connected..

function NetworkTest(runtime)
{
	var xmlHttp = new XMLHttpRequest();
	xmlHttp.open( "GET", "https://www.mysite.com", true );
	xmlHttp.setRequestHeader("Access-Control-Allow-Origin", "*");
	xmlHttp.send();
	

	xmlHttp.onerror =function ()
	{
		runtime.callFunction("Change_Connection_Status",0);//NOT CONNECTED
	}
	
	xmlHttp.onload =function ()
	{
		
		runtime.callFunction("Change_Connection_Status",1);//CONNECTED
	}
	
}

Is there a reason you don't use Browser.isOnline?

Yes, that only works on PC. It doesn't do anything on mobile. God knows why not. :(

In browser or as App? It works for me in Chrome on Android.

As an exported debug apk on device it doesn't seem to work. Does it work for you like that?

I cannot export to apk at the moment. So i tested only in browser.

If Browser.isOnLine doesn't work in apks. I would consider that as a bug. It's not mentioned that it doesn't work. I would make a bug-report.

Have you tried to use PlatformInfo.ConnectionTyp? it should return 'none' if it's not conneted, I think.

Have you tried in construct2 runtime?

However this issue is closed. I would make a new bug-report. Even it doesn't work it should mentioned in the manual.

I wouldn't bother trying to work out if you are online or not. It's surprisingly difficult to tell if you are online, e.g. suppose you can reach a few websites but not most - does that count as online? The best approach is: just go ahead and do whatever networking stuff you need to, and if it fails, you're probably not online.

I understand but there are a some points to consider:

-Even when I do my Network stuff on Android the connection always reports success regardless of whether it fails or not.

-There is a disparity between the PC version and the Android version.

For example: the following works fine on PC but reports always connected on Android with all wifi/mobile data disconeccted..why?

var xmlHttp = new XMLHttpRequest();
	
	//alert("Csxsxs");
	xmlHttp.open( "GET", "https://www.pigobo.com", true );
	xmlHttp.setRequestHeader("Access-Control-Allow-Origin", "*");
	xmlHttp.send();
	
	
	xmlHttp.onreadystatechange = function(e) {
	
		if (xmlHttp.readyState != 4) {
			runtime.callFunction("Change_Connection_Status",0);
		 return;
		}

		if (xmlHttp.status == 200) {
			runtime.callFunction("Change_Connection_Status",1);
		}
		else
		{
			runtime.callFunction("Change_Connection_Status",0);
		}
	}

-Even when I do my Network stuff on Android the connection always reports success regardless of whether it fails or not.

It shouldn't do. My best guess is it really is working, or you're getting a cached result, which you don't need to be online for.
