Android如何检测网络的类型为3G、2G、wap、wifi

 关于Android如何检测网络的类型,网上代码很多,但是有用的精品不多,前段时间,因为做项目需要涉及到具体网络类型的检查,特别是区分2G网络是为wap,还是net,类型,因为wap类型,需要配置代理上网,基于此,我将自己实现的过程代码记录下来:

  1、定义常量来标识几种网络类型

    /** 没有网络 */    public static final int NETWORKTYPE_INVALID = 0;    /** wap网络 */    public static final int NETWORKTYPE_WAP = 1;    /** 2G网络 */    public static final int NETWORKTYPE_2G = 2;    /** 3G和3G以上网络,或统称为快速网络 */    public static final int NETWORKTYPE_3G = 3;    /** wifi网络 */    public static final int NETWORKTYPE_WIFI = 4;

2、判断是否是FastMobileNetWork,将3G或者3G以上的网络称为快速网络

private static boolean isFastMobileNetwork(Context context) {TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);    switch (telephonyManager.getNetworkType()) {        case TelephonyManager.NETWORK_TYPE_1xRTT:            return false; // ~ 50-100 kbps        case TelephonyManager.NETWORK_TYPE_CDMA:            return false; // ~ 14-64 kbps        case TelephonyManager.NETWORK_TYPE_EDGE:            return false; // ~ 50-100 kbps        case TelephonyManager.NETWORK_TYPE_EVDO_0:            return true; // ~ 400-1000 kbps        case TelephonyManager.NETWORK_TYPE_EVDO_A:            return true; // ~ 600-1400 kbps        case TelephonyManager.NETWORK_TYPE_GPRS:            return false; // ~ 100 kbps        case TelephonyManager.NETWORK_TYPE_HSDPA:            return true; // ~ 2-14 Mbps        case TelephonyManager.NETWORK_TYPE_HSPA:            return true; // ~ 700-1700 kbps        case TelephonyManager.NETWORK_TYPE_HSUPA:            return true; // ~ 1-23 Mbps        case TelephonyManager.NETWORK_TYPE_UMTS:            return true; // ~ 400-7000 kbps        case TelephonyManager.NETWORK_TYPE_EHRPD:            return true; // ~ 1-2 Mbps        case TelephonyManager.NETWORK_TYPE_EVDO_B:            return true; // ~ 5 Mbps        case TelephonyManager.NETWORK_TYPE_HSPAP:            return true; // ~ 10-20 Mbps        case TelephonyManager.NETWORK_TYPE_IDEN:            return false; // ~25 kbps        case TelephonyManager.NETWORK_TYPE_LTE:            return true; // ~ 10+ Mbps        case TelephonyManager.NETWORK_TYPE_UNKNOWN:            return false;        default:            return false;        }    }

 3、获取网络类型是否是2G、3G、wap、wifi等

/**     * 获取网络状态,wifi,wap,2g,3g.     *     * @param context 上下文     * @return int 网络状态 {@link #NETWORKTYPE_2G},{@link #NETWORKTYPE_3G},          *{@link #NETWORKTYPE_INVALID},{@link #NETWORKTYPE_WAP}* <p>{@link #NETWORKTYPE_WIFI}     */    public static int getNetWorkType(Context context) {        ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);        NetworkInfo networkInfo = manager.getActiveNetworkInfo();        if (networkInfo != null && networkInfo.isConnected()) {            String type = networkInfo.getTypeName();            if (type.equalsIgnoreCase("WIFI")) {                mNetWorkType = NETWORKTYPE_WIFI;            } else if (type.equalsIgnoreCase("MOBILE")) {                String proxyHost = android.net.Proxy.getDefaultHost();                mNetWorkType = TextUtils.isEmpty(proxyHost)                        ? (isFastMobileNetwork(context) ? NETWORKTYPE_3G : NETWORKTYPE_2G)                        : NETWORKTYPE_WAP;            }        } else {            mNetWorkType = NETWORKTYPE_INVALID;        }        return mNetWorkType;    }
