Question

我想将MMS从我的应用程序发送到特定号码。我搜索并找到了这段代码，但我不知道这段代码是否需要我。我的问题是：

- 任何人都可以向我解释这个代码。我是MMS的初学者。

- 而且，我认为这段代码让用户从我的应用程序发送MMS而不将其移动到本机Messaging收件箱（这就是我想要的）我是对的吗？

- 我也有问题，我不知道如何将这段代码放入我的项目中。

这就是我发现的

彩信只是一个http-post请求。您应该使用额外的网络功能执行请求：

final ConnectivityManager connMgr =  (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
final int result = connMgr.startUsingNetworkFeature( ConnectivityManager.TYPE_MOBILE, Phone.FEATURE_ENABLE_MMS);

如果以Phone.APN_REQUEST_STARTED值返回结果，则必须等待正确的状态。注册BroadCastReciver并等待Phone.APN_ALREADY_ACTIVE出现：

final IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
context.registerReceiver(reciver, filter);

如果后台连接已准备就绪，则构建内容并执行请求。如果你想使用android的内部代码，请使用：

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();

if (parts != null) {
   for (MMSPart part : parts) {
      final PduPart partPdu = new PduPart();
      partPdu.setName(part.Name.getBytes());
      partPdu.setContentType(part.MimeType.getBytes());
      partPdu.setData(part.Data);
      pduBody.addPart(partPdu);
   }
}

sendRequest.setBody(pduBody);

final PduComposer composer = new PduComposer(this.context, sendRequest);
final byte[] bytesToSend = composer.make();

HttpUtils.httpConnection(context, 4444L, MMSCenterUrl, bytesToSendFromPDU, HttpUtils.HTTP_POST_METHOD, !TextUtils.isEmpty(MMSProxy), MMSProxy, port);

MMSCenterUrl：来自MMS-APN的网址，
MMSProxy：来自MMS-APN的代理，
port：来自MMS-APNs的端口

请注意，某些类来自内部包。从android git下载是必需的。该请求应该使用来自用户的apn-space代码的URL来完成：

public class APNHelper {

   public class APN {
      public String MMSCenterUrl = "";
      public String MMSPort = "";
      public String MMSProxy = ""; 
   }

   public APNHelper(final Context context) {
      this.context = context;
   }   

   public List<APN> getMMSApns() {     
      final Cursor apnCursor = this.context.getContentResolver().query(Uri.withAppendedPath(Telephony.Carriers.CONTENT_URI, "current"), null, null, null, null);
      if ( apnCursor == null ) {
         return Collections.EMPTY_LIST;
      } else {
         final List<APN> results = new ArrayList<APN>();         
         while ( apnCursor.moveToNext() ) {
            final String type = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.TYPE));
            if ( !TextUtils.isEmpty(type) && ( type.equalsIgnoreCase(Phone.APN_TYPE_ALL) || type.equalsIgnoreCase(Phone.APN_TYPE_MMS) ) ) {
               final String mmsc = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSC));
               final String mmsProxy = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPROXY));
               final String port = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPORT));                  
               final APN apn = new APN();
               apn.MMSCenterUrl = mmsc;
               apn.MMSProxy = mmsProxy;
               apn.MMSPort = port;
               results.add(apn);
            }
         }                   
         apnCursor.close();
         return results;
      }

请帮帮我

为什么不使用android系统功能：

请查看

https://developer.android.com/guide/components/intents-common.html

public void composeMmsMessage(String message, Uri attachment) {
       Intent intent = new Intent(Intent.ACTION_SEND);
       intent.setData(Uri.parse("smsto:"));  // This ensures only SMS apps respond
       intent.putExtra("sms_body", message);
       intent.putExtra(Intent.EXTRA_STREAM, attachment);
       if (intent.resolveActivity(getPackageManager()) != null) {
           startActivity(intent); }
}

干杯

Answer 2

我在另一个线程中找到了一个链接到github项目的链接，该项目100％https://github.com/klinker41/android-smsmms

请注意，强制性设置仅为

Settings sendSettings = new Settings();

sendSettings.setMmsc(mmsc);
sendSettings.setProxy(proxy);
sendSettings.setPort(port);

你可以得到类似的东西（在Set APN programmatically on Android找到 - 由vincent091发送）：

Cursor cursor = null;
if (Utils.hasICS()){
    cursor =SqliteWrapper.query(activity, activity.getContentResolver(), 
            Uri.withAppendedPath(Carriers.CONTENT_URI, "current"), APN_PROJECTION, null, null, null);
} else {
    cursor = activity.getContentResolver().query(Uri.withAppendedPath(Telephony.Carriers.CONTENT_URI, "current"),
        null, null, null, null);
}

cursor.moveToLast();
String type = cursor.getString(cursor.getColumnIndex(Telephony.Carriers.TYPE));
String mmsc = cursor.getString(cursor.getColumnIndex(Telephony.Carriers.MMSC));
String proxy = cursor.getString(cursor.getColumnIndex(Telephony.Carriers.MMSPROXY));
String port = cursor.getString(cursor.getColumnIndex(Telephony.Carriers.MMSPORT));
