android - Get Network type

Question

I've been trying to retrive the current network type, but no success

when i say network type: i refer to know this info: if the type is: NETWORK_TYPE_IDEN or NETWORK_TYPE_UMTS.. and so on..

i tried to use:

NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();

or

NetworkInfo mobNetInfo = connectivityManager.getNetworkInfo 
            (ConnectivityManager.TYPE_MOBILE); 

but no success..

i am doing this coz i wanna know if the current network is IDEN, or if the current network is connected through wifi..

I hate magic numbers :

/**

 */
private String networkType() {
    TelephonyManager teleMan = (TelephonyManager)
            getSystemService(Context.TELEPHONY_SERVICE);
    int networkType = teleMan.getNetworkType();
    switch (networkType) {
        case TelephonyManager.NETWORK_TYPE_1xRTT: return "1xRTT";
        case TelephonyManager.NETWORK_TYPE_CDMA: return "CDMA";
        case TelephonyManager.NETWORK_TYPE_EDGE: return "EDGE";
        case TelephonyManager.NETWORK_TYPE_EHRPD: return "eHRPD";
        case TelephonyManager.NETWORK_TYPE_EVDO_0: return "EVDO rev. 0";
        case TelephonyManager.NETWORK_TYPE_EVDO_A: return "EVDO rev. A";
        case TelephonyManager.NETWORK_TYPE_EVDO_B: return "EVDO rev. B";
        case TelephonyManager.NETWORK_TYPE_GPRS: return "GPRS";
        case TelephonyManager.NETWORK_TYPE_HSDPA: return "HSDPA";
        case TelephonyManager.NETWORK_TYPE_HSPA: return "HSPA";
        case TelephonyManager.NETWORK_TYPE_HSPAP: return "HSPA+";
        case TelephonyManager.NETWORK_TYPE_HSUPA: return "HSUPA";
