How to check the internet is active or not?

[himalayanxtiger (Himalayan Tiger)]

Hello everyone ,
We can check internet is connected or not by network component .

But how can we check either the internet connection is working or not ?

Just make a url connection to any page like google.com

If the response is okay (200) then you have a internet connection

You can call data from database backend your app. If data got then go next step. If data can’t get from database then you can show Dialog for net connection.

I put in my application that if there is internet put a wifi icon and if there is no internet put the no wifi icon.

The blocks I use are those of the Network component.

When there is no internet automatically the component detects it and does what I put in the On.Disconnect event

I think that doesn’t work, because you can’t get response without Internet connection.

Why not simply something like this:

or what @pepocero suggested.

I think that only check either internet is connected or not ,
But not internet has active connection or not.

You are getting this error because the Got Text event has not triggered because there is no internet connection. The “else” block will never work so simply use when Screen1.Error Occurred event to remove that error.

It´s true.

You can check this extension:

unfortunately that does not help in this case.

see the following link how to do it without using the Network component (which is not available in standard App Inventor) together with the Screen.ErrorOccurred event
