ConnectivityManager in Android L Preview

My app checks for Network connection when starting. In Android versions 2.3 thru 4.4 the below method works great (whether emulator or actual device). On the Android L Preview Emulator, the method comes back false.

Here is my code:

// ===============================================================
public static boolean haveNetworkConnection(Context ctx) {

    boolean haveConnectedWifi = false;
    boolean haveConnectedMobile = false;
    boolean haveConnectedEthernet = false;

    ConnectivityManager cm = (ConnectivityManager) ctx
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo[] netInfo = cm.getAllNetworkInfo();

    for (NetworkInfo ni : netInfo) {

        // String con = ni.isConnected() ? "Connected" : "Not Connected";

        if (!haveConnectedWifi) {
            if (ni.getTypeName().equalsIgnoreCase("WIFI"))
                if (ni.isConnected())
                    haveConnectedWifi = true;
        }

        if (!haveConnectedMobile) {
            if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
                if (ni.isConnected())
                    haveConnectedMobile = true;
        }

        if (!haveConnectedEthernet) {
            if (ni.getTypeName().equalsIgnoreCase("ETHERNET"))
                if (ni.isConnected())
                    haveConnectedEthernet = true;
        }

        StringBuilder sb = new StringBuilder();
        sb.append(ni.getTypeName()).append(" ").append(ni);


    }
    return haveConnectedWifi || haveConnectedMobile
            || haveConnectedEthernet;
}

There is some weird StringBuilder stuff, I did not create this code -- it is in a project I inherited. I have not needed to change anything since it works. Does anyone know if there is any API changes with how ConnectivityManager works? I checked the API overview changes on the dev site but did not see any relevant info on this.

Typename has been changed in L, for example should check "Cellular" instead of "MOBILE".
