Android 获取联网方式及代理联网
得到联网方式的方法

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; } } 

没有网络时会出现异常，位置为ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getActiveNetworkInfo();


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
