Android 提供的 TelephonyManager 和 ConnectivityManager 都可以获取到NetworksInfo对象，通过getType()获取类型，判断是wifi还是mobile，
如果是mobile ，可以通过NetworksInfo对象的getSubType()和getSubTypeName()可以获取到对于的网络类型和名字

TelephonyManager.java:

…
/* Network type is unknown /
public static final int NETWORK_TYPE_UNKNOWN = 0;
/* Current network is GPRS /
public static final int NETWORK_TYPE_GPRS = 1;
/* Current network is EDGE /
public static final int NETWORK_TYPE_EDGE = 2;
/* Current network is UMTS /
public static final int NETWORK_TYPE_UMTS = 3;
/* Current network is CDMA: Either IS95A or IS95B/
public static final int NETWORK_TYPE_CDMA = 4;
/* Current network is EVDO revision 0/
public static final int NETWORK_TYPE_EVDO_0 = 5;
/* Current network is EVDO revision A/
public static final int NETWORK_TYPE_EVDO_A = 6;
/* Current network is 1xRTT/
public static final int NETWORK_TYPE_1xRTT = 7;
/* Current network is HSDPA /
public static final int NETWORK_TYPE_HSDPA = 8;
/* Current network is HSUPA /
public static final int NETWORK_TYPE_HSUPA = 9;
/* Current network is HSPA /
public static final int NETWORK_TYPE_HSPA = 10;
/* Current network is iDen /
public static final int NETWORK_TYPE_IDEN = 11;
/* Current network is EVDO revision B/
public static final int NETWORK_TYPE_EVDO_B = 12;
/* Current network is LTE /
public static final int NETWORK_TYPE_LTE = 13;
/* Current network is eHRPD /
public static final int NETWORK_TYPE_EHRPD = 14;
/* Current network is HSPA+ /
public static final int NETWORK_TYPE_HSPAP = 15;
