Question

我正在尝试构建自己的消息收发应用程序，并且正在尝试设置彩信。我想通过MMS发送一些额外的信息（例如groupName和其他一些元数据）。我能够使用Android SmsManager.sendMultimediaMessage()和SmsManager.downloadMultimediaMessage()功能成功发送MMS消息。从文档看来，我应该可以使用configOverrides发送更多信息。但是，当我尝试下载彩信时，configOverrides始终为空...

发送彩信的代码：

  Bundle configOverrides = new Bundle();
  configOverrides.putBoolean(SmsManager.MMS_CONFIG_GROUP_MMS_ENABLED, true);

  MmsConfig mmsConfig = MmsConfigManager.getMmsConfig(getContext(), subscriptionId);

  if (mmsConfig != null) {
    MmsConfig.Overridden overridden = new MmsConfig.Overridden(mmsConfig, new Bundle());
    String tempHttpParams = overridden.getHttpParams();
    if(tempHttpParams == null || tempHttpParams.equals("")) {
      tempHttpParams = "groupName=test";
    } else {
      tempHttpParams += "|groupName=test";
    }
    Log.d(TAG, "httpParams: " + tempHttpParams);
    configOverrides.putString(SmsManager.MMS_CONFIG_HTTP_PARAMS, tempHttpParams);
    configOverrides.putInt(SmsManager.MMS_CONFIG_MAX_MESSAGE_SIZE, overridden.getMaxMessageSize());
    Log.d(TAG, "configOverride: " + configOverrides.toString());
  }

  smsManager.sendMultimediaMessage(getContext(),
                                   pointer.getUri(),
                                   null,
                                   configOverrides,
                                   getPendingIntent());

下载彩信的代码：

  Bundle configOverrides = new Bundle();

  smsManager.downloadMultimediaMessage(getContext(),
                                       contentLocation,
                                       pointer.getUri(),
                                       configOverrides,
                                       getPendingIntent());

  waitForResult();

  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  Util.copy(pointer.getInputStream(), baos);
  pointer.close();

  Log.i(TAG, baos.size() + "-byte response: ");// + Hex.dump(baos.toByteArray()));

  RetrieveConf retrieved = (RetrieveConf) new PduParser(baos.toByteArray()).parse();

  Log.d(TAG, "configOverrides: " + configOverrides.toString());
  Log.d(TAG, "httpParams: " + configOverrides.getString(SmsManager.MMS_CONFIG_HTTP_PARAMS));

  Log.d(TAG, "smsManager.getCarrierConfigValues(): " + smsManager.getCarrierConfigValues().toString());

记录详细信息：

D/OutgoingLollipopMmsConnection: httpParams: groupName=test
D/OutgoingLollipopMmsConnection: configOverride: Bundle[{httpParams=groupName=test, enableGroupMms=true, maxMessageSize=1048576}]

I/IncomingLollipopMmsConnection: 350101-byte response: 
D/IncomingLollipopMmsConnection: configOverrides: Bundle[{}]
D/IncomingLollipopMmsConnection: httpParams: null
D/IncomingLollipopMmsConnection: smsManager.getCarrierConfigValues(): Bundle[mParcelledData.dataSize=1648]

我环顾四周，使用configOverrides找不到用户的任何示例。我是否缺少有关如何下载它们的步骤？还是有更好的方法通过MMS发送额外的元数据？（我知道在Lollipop开发人员必须构建自己的MMS api之前，它们基本上只是HTTP Post消息，但我认为使用Android API会很好。）

MMS configOverrides未发送
