程序中透过wap联网方式访问网络

程序中通过wap联网方式访问网络
用户的联网方式大致有 wap net wifi 三种. 使用android包中提供的函数,HttpConnection只能使用net和wifi,wap方式无法访问. 

问? 如何让程序可以通过wap访问网络?

------解决方案--------------------

if(bUsingProxy){
				conn.setRequestProperty("X-Online-Host", host);
			}
			conn.setRequestProperty("Accept", "text/plain");
			conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
			conn.setRequestProperty("Connection", "Close");
			conn.setRequestProperty("Content-Length", String.valueOf(data.length));
			conn.connect();

给个完整的

private void doPost() throws IOException{
		
		StringBuilder builder = new StringBuilder();
		builder.append("http://");
		
		if(bUsingProxy){
			builder.append(proxy);
		}else{
			builder.append(host);
		}
		
		if(urlpage != null){
			builder.append("/" + urlpage);
		}
		
		String desturl = builder.toString();
		InputStream stream = null; 
		HttpURLConnection conn = null;
		try{
			byte[] data = params.getBytes();
			
			URL url = new URL(desturl);
			conn = (HttpURLConnection) url.openConnection();
			conn.setRequestMethod("POST");

			conn.setConnectTimeout(connectTimeout);
			conn.setReadTimeout(readTimeout);
			conn.setDoOutput(true);
			conn.setUseCaches(false);
			if(bUsingProxy){
				conn.setRequestProperty("X-Online-Host", host);
			}
			conn.setRequestProperty("Accept", "text/plain");
			conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
			conn.setRequestProperty("Connection", "Close");
			conn.setRequestProperty("Content-Length", String.valueOf(data.length));
			conn.connect();
			
			OutputStream outputStream = conn.getOutputStream();
			outputStream.write(data);
			outputStream.flush();
			outputStream.close();
			
			int resp_code = conn.getResponseCode();
			Map<String, List<String>> headerMap = conn.getHeaderFields();
