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
