Android Http连接有时在ctnet（cmnet）下很正常，可是有时候在用户选择ctwap（cmwap）时就会没有反应，这是因为wap是，只能访问IP为10.*。*。*的IP地址，这时候需要使用代理。总的来说有以下三种方式：
（方式一）：
一个是Java.net包中的：HttpURLConnection，它设置代理代码如下：
Proxy proxy=new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress(“10.0.0.172″,80));
HttpURLConnection connection=(HttpURLConnection) url.openConnection(proxy);
还有一个是Apache的HttpClient：
DefaultHttpClient httpclient = new DefaultHttpClient(); HttpHost proxy = new HttpHost(“10.0.0.172″, 80); httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
（方式二）：
URL url = new URL("http://10.0.0.172/img/baidu_logo.gif");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("X-Online-Host", "www.baidu.com");
//J2ME设置CMWAP代理上网
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
bitmap = BitmapFactory.decodeStream(is);
is.close();
conn.disconnect();
或者：
imageUrl = "http://www.baidu.com/img/baidu_logo.gif“；
Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP, new InetSocketAddress("10.0.0.200", 80));
HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection(proxy);
conn.connect();
InputStream is = conn.getInputStream();
bitmap = BitmapFactory.decodeStream(is);
is.close();
conn.disconnect();
（方式三）：
java.net.Proxy p = new java.net.Proxy(java.net.Proxy.Type.HTTP,
new InetSocketAddress(android.net.Proxy.getDefaultHost(),
android.net.Proxy.getDefaultPort()));
conn = (HttpURLConnection) url.openConnection(p);
Log.v("http", "httpdaili");
