This article illustrates a Java method for getting network types. Share with you for your reference. The details are as follows:

 
public static String getNetType(Context context) { 
try { 
ConnectivityManager connectMgr = (ConnectivityManager) context 
.getSystemService(Context.CONNECTIVITY_SERVICE); 
NetworkInfo info = connectMgr.getActiveNetworkInfo(); 
if (info == null) { 
return ""; 
} 
if (info.getType() == ConnectivityManager.TYPE_WIFI) { 
return "WIFI"; 
} else if (info.getType() == ConnectivityManager.TYPE_MOBILE) { 
if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_CDMA) { 
return "CDMA"; 
} else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_EDGE) { 
return "EDGE"; 
} else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_EVDO_0) { 
return "EVDO0"; 
} else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_EVDO_A) { 
return "EVDOA"; 
} else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_GPRS) { 
return "GPRS"; 
} 
 
else if (info.getSubtype() == TelephonyManager.NETWORK_TYPE_UMTS) { 
return "UMTS"; 
} else { 
return "3G"; 
}
