android代理联网，wap方式联网

获取联网方式

public String NetType(Context context) {
 try {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getActiveNetworkInfo();
 String typeName = info.getTypeName().toLowerCase; // WIFI/MOBILE
 if(typeName.equals.("wifi")){
 }else{
typeName = mActiveNetworkInfo.getExtraInfo().toLowerCase();
 //3gnet/3gwap/uninet/uniwap/cmnet/cmwap/ctnet/ctwap
}
 return typeName;
 } catch (Exception e) {
 return null;
}
 }   没有网络时ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo info = cm.getActiveNetworkInfo(); 会出现异常。

 

 

 

 

使用代理联网时得到连接对象的方法

private HttpURLConnection getURLConnection(String url) throws Exception {
String proxyHost = android.net.Proxy.getDefaultHost();
 if (proxyHost != null) {
 java.net.Proxy p = new java.net.Proxy(java.net.Proxy.Type.HTTP,
 new InetSocketAddress(android.net.Proxy.getDefaultHost(),
android.net.Proxy.getDefaultPort()));

 return (HttpURLConnection) new URL(url).openConnection(p);

 } else {
 return (HttpURLConnection) new URL(url).openConnection();
}
}

返回HttpURLConnection对象android.net.Proxy.getDefaultHost()得到手机设置的代理ip，得到android.net.Proxy.getDefaultPort()得到手机设置的端口；
也可以自己设置为 10.0.0.172 端口 80
