//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 转载： －－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－ 变量定义 Cursor cursor_current,cursor_need; Uri PREFERRED_APN_URI, APN_TABLE_URI; int newCreateAPN_Id; String APN_Id; TelephonyManager tm; WifiManager wifi; String strAPN; 使用到的函数如下： //获取当前APN属性 private boolean getCurrentAPN(){ PREFERRED_APN_URI = Uri.parse("content://telephony/carriers/preferapn"); cursor_current = this.getContentResolver().query(PREFERRED_APN_URI, null, null, null, null); if(cursor_current != null && cursor_current.moveToFirst()){ String proxy = cursor_current.getString(cursor_current.getColumnIndex("proxy"));

} } return false; } //检查是否存在cmwap网络 private boolean checkHasWapAPN(){ APN_TABLE_URI = Uri.parse("content://telephony/carriers"); cursor_need = this.getContentResolver().query(APN_TABLE_URI, null, null, null, null);

String current = cursor_need.getString(cursor_need.getColumnIndex("current")); String mmsc = cursor_need.getString(cursor_need.getColumnIndex("mmsc")); if(proxy == null || port == null || current == null){ continue;

ContentResolver resolver = this.getContentResolver(); ContentValues values = new ContentValues(); values.put("apn_id", id); try{ resolver.update(PREFERRED_APN_URI, values, null, null); Cursor c = resolver.query(PREFERRED_APN_URI, new String[]{"name", "apn"}, "_id=" + id, null, null); if(c != null){ res = true; c.close(); } }catch(SQLException e){ Log.e("lhl", e.getMessage()); } return res; } //添加cmwap网络 private int addCmwapAPN(){ ContentResolver cr = this.getContentResolver(); ContentValues cv = new ContentValues();

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; } －－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－ 注意：加上权限 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission> <uses-permission android:name="android.permission.WRITE_APN_SETTINGS"></uses-permission> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
