Good evening,

How can I create an error code?
can you give me an example?

Since my app doesn't load without internet, I would like to get the error "no internet connection, try again"
how can I do it?

Thanks

Use Power User vknow360's extension "Net". Call it when an internet connection needs to be made.

Since I have to put it on screen 1 when the app loads, it's not for the web, I wanted to understand what code to insert

Can you re-word that Bernardino? I don't understand. Your Blocks do not show vknow360's 'Net' extension?

When your App needs to connect to the internet, first use the extension to check if your device has an internet connection. If yes, just allow the App to connect, if no, use a Notification to inform the User.

right?

Because when there is no connection the application closes without any warning

Test your App as an APK.
