android 判断 网络 类型

1.获取sim卡类型

private static int getMobileType(Context context)

{

int type = -1; //无卡

TelephonyManager iPhoneManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

String iNumeric = iPhoneManager.getSimOperator();

if (iNumeric.length() > 0)

{

if (iNumeric.equals("46000") || iNumeric.equals("46002"))

{

// 中国移动

type=0;

}

else if (iNumeric.equals("46001"))

{

// 中国联通

type=1;

}

else if (iNumeric.equals("46003"))

{

// 中国电信

type=2;

}

}

return type;

}

2./** 获取网络信息 */

// 网络状态

public static final String UNKNWON = "unkwon";

public static final String NOT_AVAILABLE = "not_avaible";

public static final String WIFI = "wifi";

public static final String G3NET = "3gnet";

public static final String G3WAP = "3gwap";

public static final String CMWAP = "cmwap";

public static final String CTNET = "ctnet";

public static final String CTWAP = "ctwap";

public static final String MOBILE = "mobile";

public static String getNetApn() {

if (CenterApp.getContext().checkCallingOrSelfPermission("android.permission.ACCESS_NETWORK_STATE") == PackageManager.PERMISSION_DENIED) {

return UNKNWON;

}

ConnectivityManager connectivitymanager = (ConnectivityManager) CenterApp.getContext().getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo networkinfo = connectivitymanager.getActiveNetworkInfo();

if (networkinfo == null || !networkinfo.isAvailable()) {

return NOT_AVAILABLE;

}

if (networkinfo.getType() == ConnectivityManager.TYPE_WIFI) {

return WIFI;

}

String netInfo = networkinfo.getExtraInfo();

if (netInfo == null) {

return UNKNWON;

}

netInfo = netInfo.toLowerCase();

if (netInfo.equals("cmnet")) {

return CMNET;

} else if (netInfo.equals("cmwap")) {

return CMWAP;

} else if (netInfo.equals("3gnet")) {

return G3NET;

} else if (netInfo.equals("3gwap")) {

return G3WAP;

} else if (netInfo.equals("uninet")) {

return UNINET;

} else if (netInfo.equals("uniwap")) {

} else if (netInfo.equals("ctnet")) {

} else if (netInfo.equals("ctwap")) {

} else {

return MOBILE;

}
