android 自定义发送彩信的问题

程序cmwap连不上网络，发送不成功，怎么会这样，代码是网上找的，通过logcat看连接超时，大家帮我看看，是哪里出问题了

private static final String TAG = "MMSSender";
        public static String mmscUrl = "http://mmsc.monternet.com";
        public static String mmsProxy = "10.0.0.172";
        public static int mmsProt = 80;

        private static String HDR_VALUE_ACCEPT_LANGUAGE = "";
        private static final String HDR_KEY_ACCEPT = "Accept";
        private static final String HDR_KEY_ACCEPT_LANGUAGE = "Accept-Language";
        private static final String HDR_VALUE_ACCEPT = "*/*, application/vnd.wap.mms-message, application/vnd.wap.sic";

        public static byte[] sendMMS(Context context, byte[] pdu)
                        throws IOException {
                System.out.println("进入sendMMS方法");
                // HDR_VALUE_ACCEPT_LANGUAGE = getHttpAcceptLanguage();
                HDR_VALUE_ACCEPT_LANGUAGE = HTTP.UTF_8;
                if (mmscUrl == null) {
                        throw new IllegalArgumentException("URL must not be null.");
                }

                HttpClient client = null;
try{
         HttpHost httpHost = new HttpHost(mmsProxy, mmsProt);
                        HttpParams httpParams = new BasicHttpParams();
                        httpParams.setParameter(ConnRouteParams.DEFAULT_PROXY, httpHost);
                        HttpConnectionParams.setConnectionTimeout(httpParams, 10000);

                        client = new DefaultHttpClient(httpParams);
                        HttpPost post = new HttpPost(mmscUrl);

                        // mms PUD START
                        ByteArrayEntity entity = new ByteArrayEntity(pdu);
                        entity.setContentType("application/vnd.wap.mms-message");
                        post.setEntity(entity);
                        post.addHeader(HDR_KEY_ACCEPT, HDR_VALUE_ACCEPT);
                        post.addHeader(HDR_KEY_ACCEPT_LANGUAGE, HDR_VALUE_ACCEPT_LANGUAGE);
                        post.addHeader("user-agent", "Mozilla/5.0(Linux;U;Android 2.1-update1;zh-cn;ZTE-C_N600/ZTE-C_N600V1.0.0B02;240*320;CTC/2.0)AppleWebkit/530.17(KHTML,like Gecko) Version/4.0 Mobile Safari/530.17");
                        // mms PUD END

                        HttpParams params = client.getParams();
                        HttpProtocolParams.setContentCharset(params, "UTF-8");

                        System.out.println("准备执行发送");
                        Log.v("MMSSender", "准备执行发送");

                        HttpResponse response = client.execute(post); Android 网络 --------------------编程问答-------------------- 只能运行到最后一行 HttpResponse response = client.execute(post);

然后就报错连接超时  connect 10.0.0.172:80 time out

崩溃啊 --------------------编程问答-------------------- 呵呵，解决了，是pdu格式错了，呵呵，可以发送了，来个人吧，把分给了 --------------------编程问答-------------------- 请问你是如何解决的，我现在遇到与你同样的问题。一直报错连接超时  connect 10.0.0.172:80 time out现在不知道怎么解决。请问pdu格式数据如何封装？ --------------------编程问答-------------------- 刚才忘给你联系方式了,我的QQ：742264104，邮箱：zhanqi889@163.com --------------------编程问答-------------------- 楼主，你是如何解决的啊？ --------------------编程问答-------------------- 能给个代码吗，qq:245227506  Email 245227506@qq.com
