android 实现发送彩信方法 (MMS)，非调用系统彩信界面

最近有个需求，不去调用系统界面发送彩信功能。做过发送短信功能的同学可能第一反应是这样：
不使用 StartActivity，像发短信那样，调用一个类似于发短信的方法
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneCode, null, text, null, null);
可以实现吗？ 答案是否定的，因为android上根本就没有提供发送彩信的接口，如果你想发送彩信，对不起，请调用系统彩信app界面，如下： 

Intent sendIntent = new Intent(Intent.ACTION_SEND,  Uri.parse("mms://"));
    sendIntent.setType("image/jpeg");
    String url = "file://sdcard//tmpPhoto.jpg";
    sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url));
    startActivity(Intent.createChooser(sendIntent, "MMS:"));

Intent sendIntent = new Intent(Intent.ACTION_SEND, Uri.parse("mms://")); sendIntent.setType("image/jpeg"); String url = "file://sdcard//tmpPhoto.jpg"; sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url)); startActivity(Intent.createChooser(sendIntent, "MMS:"));

 

但是这种方法往往不能满足我们的需求，能不能不调用系统界面，自己实现发送彩信呢？经过几天的努力，终于找到了解决办法。

第一步：先构造出你要发送的彩信内容，即构建一个pdu，需要用到以下几个类，这些类都是从android源码的MMS应用中mms.pdu包中copy出来的。你需要将pdu包中的所有类

都拷贝到你的工程中，然后自己酌情调通。

  
  
  
  
   final SendReq sendRequest = new SendReq ();
   final PduBody pduBody = new PduBody();
final PduPart part = new PduPart();//存放附件，每个附件是一个part，如果添加多个附件，就想body中add多个part。
   pduBody.addPart(partPdu);
   sendRequest.setBody(pduBody);
   final PduComposer composer = new PduComposer(ctx, sendRequest);
final byte[] bytesToSend = composer.make(); //将彩信的内容以及主题等信息转化成byte数组，准备通过http协议发送到 "http://mmsc.monternet.com";
   final SendReq sendRequest = new SendReq ();
   final PduBody pduBody = new PduBody();
final PduPart part = new PduPart();//存放附件，每个附件是一个part，如果添加多个附件，就想body中add多个part。
   pduBody.addPart(partPdu);
   sendRequest.setBody(pduBody);
   final PduComposer composer = new PduComposer(ctx, sendRequest);
final byte[] bytesToSend = composer.make(); //将彩信的内容以及主题等信息转化成byte数组，准备通过http协议发送到 "http://mmsc.monternet.com";

 第二步：发送彩信到彩信中心。

 构建pdu的代码：

 
  
  
  
  
 String subject = "测试彩信";
            String recipient = "接收彩信的号码";//138xxxxxxx
            final SendReq sendRequest = new SendReq();
            final EncodedStringValue[] sub = EncodedStringValue.extract(subject);
            if (sub != null && sub.length > 0) {
                sendRequest.setSubject(sub[0]);
            }
            final EncodedStringValue[] phoneNumbers = EncodedStringValue.extract(recipient);
            if (phoneNumbers != null && phoneNumbers.length > 0) {
                sendRequest.addTo(phoneNumbers[0]);
            }
            final PduBody pduBody = new PduBody();
            final PduPart part = new PduPart();
            part.setName("sample".getBytes());
            part.setContentType("image/png".getBytes());
            String furl = "file://mnt/sdcard//1.jpg";

                    final PduPart partPdu = new PduPart();
                    partPdu.setCharset(CharacterSets.UTF_8);//UTF_16
                    partPdu.setName(part.getName());
                    partPdu.setContentType(part.getContentType());
                    partPdu.setDataUri(Uri.parse(furl));
                    pduBody.addPart(partPdu);

            sendRequest.setBody(pduBody);
            final PduComposer composer = new PduComposer(ctx, sendRequest);
            final byte[] bytesToSend = composer.make();

            Thread t = new Thread(new Runnable() {

                @Override
                public void run() {
                    try {
                        HttpConnectInterface.sendMMS(ctx,  bytesToSend);
//
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            });
            t.start();
发送pdu到彩信中心的代码：
        public static String mmscUrl = "http://mmsc.monternet.com";
//  public static String mmscUrl = "http://www.baidu.com/";
    public static String mmsProxy = "10.0.0.172";
    public static String mmsProt = "80";

       private static String HDR_VALUE_ACCEPT_LANGUAGE = "";
    // Definition for necessary HTTP headers.
       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{
        HDR_VALUE_ACCEPT_LANGUAGE = getHttpAcceptLanguage();

        if (mmscUrl == null) {
            throw new IllegalArgumentException("URL must not be null.");
        }

        HttpClient client = null;
        try {
            // Make sure to use a proxy which supports CONNECT.
            client = HttpConnector.buileClient(context);
            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);
            //mms PUD END
            HttpParams params = client.getParams();
            HttpProtocolParams.setContentCharset(params, "UTF-8");
            HttpResponse response = client.execute(post);

            LogUtility.showLog(tag, "111");

                LogUtility.showLog(tag, "!200");
                throw new IOException("HTTP error: " + status.getReasonPhrase());
            }

                        body = new byte[(int) resentity.getContentLength()];
                        DataInputStream dis = new DataInputStream(resentity.getContent());
                        try {
                            dis.readFully(body);
                        } finally {
                            try {
                                dis.close();
                            } catch (IOException e) {

                            }
                        }
                    }
                } finally {
                    if (entity != null) {
                        entity.consumeContent();
                    }
                }
            }
            LogUtility.showLog(tag, "result:"+new String(body));
            return body;
        }  catch (IllegalStateException e) {
