android获取CMNET、WIFI、CMWAP联网状态

private static final int CMNET=1;
private static final int CMWAP=2;
private static final int WIFI=3;

public static int getAPNType(Context context){

        int netType = -1; 

        ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();

        

        if(networkInfo==null){

            return netType;

        }

        int nType = networkInfo.getType();

        if(nType==ConnectivityManager.TYPE_MOBILE){

            Log.e("networkInfo.getExtraInfo()", "networkInfo.getExtraInfo() is "+networkInfo.getExtraInfo());

            if(networkInfo.getExtraInfo().toLowerCase().equals("cmnet")){

                netType = CMNET;

            }

            else{

                netType = CMWAP;

            }

        }

        else if(nType==ConnectivityManager.TYPE_WIFI){

            netType = WIFI;

        }

        return netType;

    }

//获取网络连接管理者
   ConnectivityManager connectionManager = (ConnectivityManager)
                          getSystemService(CONNECTIVITY_SERVICE);   
    //获取网络的状态信息，有下面三种方式
NetworkInfo networkInfo = connectionManager.getActiveNetworkInfo();
NetworkInfo 有一下方法
getDetailedState()：获取详细状态。
    getExtraInfo()：获取附加信息。
    getReason()：获取连接失败的原因。
    getType()：获取网络类型(一般为移动或Wi-Fi)。
    getTypeName()：获取网络类型名称(一般取值“WIFI”或“MOBILE”)。
    isAvailable()：判断该网络是否可用。
    isConnected()：判断是否已经连接。
    isConnectedOrConnecting()：判断是否已经连接或正在连接。
    isFailover()：判断是否连接失败。
    isRoaming()：判断是否漫游
当用wifi上的时候
getType 是WIFI
getExtraInfo是空的当用手机上的时候
getType 是MOBILE

用移动CMNET方式
getExtraInfo 的值是cmnet
用移动CMWAP方式
getExtraInfo 的值是cmwap   但是不在代理的情况下访问普通的网站访问不了
用联通3gwap方式
getExtraInfo 的值是3gwap
用联通3gnet方式
getExtraInfo 的值是3gnet
用联通uniwap方式
getExtraInfo 的值是uniwap
用联通uninet方式
getExtraInfo 的值是uninet

判断逻辑如下：
                private Search search;
                //网络判断
               
                //如果wifi是打开的，则直接调用就可以了
                    wifi = (WifiManager)getSystemService(Context.WIFI_SERVICE);
                    if(wifi.isWifiEnabled()){
                            strAPN = "WIFI";
                            search.asyncRequest(queryCompanyName, queryDttime, queryBeginCity, queryEndCity, queryBeginCity1, queryEndCity1, strAPN, listener);
                            return;
                    }
                   
            boolean isCmwap = getCurrentAPN();
            boolean wCheckWapApn = checkHasWapAPN();
            if(!isCmwap){       
                    if(!wCheckWapApn){
                            newCreateAPN_Id = addCmwapAPN();
                            strAPN = "CMNET";
                    }
                    else{
                            strAPN = "CMNET";
                    }try{
                            Thread.sleep(1000);
                    }catch(InterruptedException e){
                            e.printStackTrace();
                    }
            }
            else{
                    strAPN = "CMWAP";
            }
            //异步调用
            search.asyncRequest(woeid, strAPN, listener);                 

            //异步调用类：
package com.search.weather;

import com.search.RequestListener;
import com.search.common.HttpUtils;

import android.os.Bundle;
import android.util.Log;

/**
* 查询类
* @author Administrator
*
*/
public class Search {
       
        private static final String HTTP_URL = "http://sds.XXXXXX.com/getinfo";
        private static final String HTTP_WAP_URL = "http://10.0.0.172/getinfo";
        private static final String METHOD = "GET";
        private static final String LOG_TAG = "XXX";
       
       
        public String request(String strAPN){
                if(woeid != null){
                        Bundle params = new Bundle();
                       
                       
                        if (strAPN.equals("CMWAP"))
                        {
                                return HttpUtils.openUrl1(HTTP_WAP_URL, METHOD, params,null,strAPN);                               
                        }
                        else
                        {
                                return HttpUtils.openUrl(HTTP_URL, METHOD, params,null,strAPN);
                        }                       
                }else{
                        return null;
                }
        }
       
        //异步封装
        public void asyncRequest(final String strAPN, final RequestListener listener){
               
                new Thread(new Runnable() {
                       
                        @Override
                        public void run() {
                               
                                try {
                                        String response = request(strAPN);
                                        listener.onComplete(response);
                                } catch (Exception e) {
                                        Log.e(LOG_TAG, e.getMessage());
                                        listener.onException(e);
                                }
                               
                        }
                }).start();
        }

}
对于CMWAP的方法需要做以下逻辑处理：

        public static String openUrl(String url, String method, Bundle params, String enc, String strAPN){
               
                String response = null;
               
                if(method.equals("GET")){
                        url = url + "?" + encodeUrl(params);
                }
               
                try {
                        //Log.d(LOG_TAG, "Url:"+url);                       
                        HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
                       
                        conn.setRequestProperty("User-Agent", System.getProperties()
                                        .getProperty("http.agent")
                                        );
                        if (strAPN.equals("CMWAP"))
                        {
                                conn.setRequestProperty("X-Online-Host", "sds.XXXXXX.com");//这里需要换成调用的真正的网址
                                conn.setDoInput(true);
                        }
                       
                        conn.setConnectTimeout(30000);
                        conn.setReadTimeout(30000); //设置超时时间
                       
                        if(method.equals("POST")){
                                conn.setRequestMethod("POST");
                                conn.setDoOutput(true);
                                conn.getOutputStream().write(encodeUrl(params).getBytes("UTF-8"));
                        }
                        response = read(conn.getInputStream(),enc);
                } catch (Exception e) {
                        //Log.e(LOG_TAG, e.getMessage());
                        throw new RuntimeException(e.getMessage(),e);
                }
                return response;
        }
