[置顶] android 实现发送彩信方法 (MMS)，非调用系统彩信界面

5进制-android技术开发博客

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/";

 "*/*, application/vnd.wap.mms-message, application/vnd.wap.sic";
public static byte[] sendMMS(Context context, byte[] pdu)throws IOException{

 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);

 //mms PUD END
 HttpParams params = client.getParams();
 HttpProtocolParams.setContentCharset(params, "UTF-8");
 HttpResponse response = client.execute(post);

 LogUtility.showLog(tag, "111");
 StatusLine status = response.getStatusLine();
 LogUtility.showLog(tag, "status "+status.getStatusCode());
 if (status.getStatusCode() != 200) { // HTTP 200 is not success.
 LogUtility.showLog(tag, "!200");
 throw new IOException("HTTP error: " + status.getReasonPhrase());
 }
 HttpEntity resentity = response.getEntity();
 byte[] body = null;
 if (resentity != null) {
 try {
 if (resentity.getContentLength() > 0) {
 body = new byte[(int) resentity.getContentLength()];
 DataInputStream dis = new DataInputStream(resentity.getContent());
 try {
 dis.readFully(body);
 } finally {
 try {
 dis.close();
 } catch (IOException e) {
 Log.e(tag, "Error closing input stream: " + e.getMessage());
 }
 }
 }
 } finally {
 if (entity != null) {
 entity.consumeContent();
 }
 }
 }
 LogUtility.showLog(tag, "result:"+new String(body));
 return body;
 } catch (IllegalStateException e) {
 LogUtility.showLog(tag, "",e);
// handleHttpConnectionException(e, mmscUrl);

 } finally {
 if (client != null) {
// client.;
 }
 }
 return new byte[0];
 }

至此，彩信的发送算是完成了。
总结：android的彩信相关操作都是没有api的，包括彩信的读取、发送、存储。这些过程都是需要手动去完成的。想要弄懂这些过程，需要仔细阅读android源码中的mms这个app。还有就是去研究mmssms.db数据库，因为彩信的读取和存储其实都是对mmssms.db这个数据库的操作过程。而且因为这个是共享的数据库，所以只能用ContentProvider这个组件去操作db。

总之，想要研究彩信这块(包括普通短信)，你就必须的研究mmssms.db的操作方法，多多了解每个表对应的哪个uri，每个uri能提供什么样的操作，那些字段代表短信的那些属性等。
最后推荐个好用的sqlite查看工具：SQLite Database Browser。
