Answer 1

If anyone is still searching for this one. The solution for me was to register a broadcast receiver in my activity to detect connection change.

    @Override
protected void onPause() {
    super.onPause();

    if (connectivityChangeReceiver!=null) unregisterReceiver(connectivityChangeReceiver);
}

@Override
protected void onResume()
{
    super.onResume();

    IntentFilter intentFilter = new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE");
    registerReceiver(connectivityChangeReceiver,intentFilter);
}

private BroadcastReceiver connectivityChangeReceiver = new BroadcastReceiver() {

    public void onReceive(Context context, Intent intent) 
    {
        mWebView.setNetworkAvailable(isNetworkAvailable(context));
    }
};

Make sure that you provide below permissions in the AndroidMenifest.xml file:

<uses-permission android:name="android.permission.INTERNET />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Answer 3

you might want to add the following line of code for your events

document.addEventListener("online", onOnline, false);
document.addEventListener("offline", onOffline, false);

make sure you check the values in the functions function onOnline(){} & function onOffline(){}

Are you sure you are not mistaking the spelling?

it should be navigator.onLine (camelCase)
