Kivy : If there is no Internet, Show me Warning Message?

[Mecra Yavcin]

Hi Kivy Masters.

I have an app and i need a function that if there is no internet, i want the app to show an message that Please activate your wifi or internet connection (a warning message).

I created my app with buildozer and Internet is necessarry.

If there is no internet, when i try to run, it it does not run so i need an error message for this.

How can i do that? 
I need some example codes.

Could you Please help me?

Thanks very much

How are you accessing the network? Are you using https://kivy.org/doc/stable/api-kivy.network.urlrequest.html#module-kivy.network.urlrequest

Thanks very much

this is my function

def datas(self, *args):          

       

        try:

            source = requests.get("http://11.11.11.11/tek.json").json()

            print('updated')

            self.data = source    

            return source

        except:

            source = {"home": {"Database": [0, 0, 0, 0, 0, 0, 0, 0, 0], "Please": [0, 0, 0, 0, 0, 0, 0, 0, 0]}, "away": {"Is Being Updated":  [0, 0, 0, 0, 0, 0, 0, 0, 0], "Try Again Later":  [0, 0, 0, 0, 0, 0, 0, 0, 0]}, "today": {"home": ["Database", "Please"], "away": ["Is Being Updated", "Try Again Later"]}}

            self.data = source    

            return source

If there is a problem in json file it uses datas that in except section 

But if there is no internet i need a wardining message.

I used import requests

Use kivy’s url request, it is asynchronous. It provides callbacks for error (and success) conditions.

You can also try using the timeout from requests.

Not a Kivy question Google:   python test internet connection
And see how to use request timeout, for example
