    When I run my program on my computer, the App::isOnline property is always True even if i do not have internet connection. And when i use it on my Android phone it becomes True when the phone is connected to a Wifi, even if this wifi does not have internet connection. Please help me ! I have to solve this problem asap.

    Hi Alex,

    the isOnline property indicates that the device is either connected to cellular data network or to a wireless network, and thus able to connect to the internet. We are using the native device signals for this. To check if this network connection actually transfers data to/from the internet, you’d need to add your own check on top. What type of app are you developing?

    Cheers,
    Alex

    Hi,

    one possible solution is to actively send a web request to a page you assume is always reachable if there’s a valid internet connection. For example to try reaching “www.google.com” (or your custom web service you are going to use in your requests). If you retrieve a result successfully, you can assume you are connected to the internet. If you reach a time-out or an error during the test-request, you probably don’t have a stable connection.

    Best,
    Günther
