Question

I am developing an Android application.

I want my application to notify me whether Android has internet connection or not. How do I check it?

@Carlo: The simplest way is first to add ACCESS_NETWORK_STATE permission to your application manifest file and write a function like this

public boolean isOnline() {
    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo netInfo = cm.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnectedOrConnecting()) {
        return true;
    }
    return false;
}

if the return value is true means internet is working or false means show an alert box 🙂
