解决：insert Vodafone sim card,open the mms read report,when receive the read report,cann't download..
insert Vodafone sim card,open the mms read report,when receive the read report,cann't download the message
Test steps:
1.insert Vodafone sim card
2.open the mms read report
3.send the mms successfully
4.when receive the read report
这里的环境须要描写叙述一下：在国内不会出现这个问题，该问题在土耳其測试发现，经过分析主要因国内外网络差异导致。
问题大概意思是在国外发送一条彩信。对方成功接收。发送方測试会接收一条阅读报告。
该阅读报告是以彩信的方式接收。这个时候问题来了。彩信无法自己主动下载，点击下载button也无法完毕下载（这里从界面时的确能够这么理解，分析代码之后才发现彩信数据已经下载成功，仅仅是在解析的时候格式不兼容导致解析发生异常，返回null。
）
因此经过分析打开NotificationTransaction.java中的log，从log中得到已经下载好的彩信数据，然后在国内用此模拟数据来解决这个问题。
if (retrieveConfData != null) {(这里加入凝视的意思也就是在这里输出log，得到国外模拟数据，然后在国内进行模拟測试）
//if (Log.isLoggable(LogTag.TRANSACTION, Log.DEBUG)) {
Log.v(TAG, "NotificationTransaction: retrieve data=" +
HexDump.dumpHexString(retrieveConfData));//HexDump这个工具类非常重要。假设有时间大家细致阅读一下源代码（能够将16进制字符串和字节数组进行转换）
//}
当然，终于改动解决这个问题的实在解析pdu和持久化保存的PduParser.java类。
case PduHeaders.MESSAGE_TYPE_RETRIEVE_CONF:
if (LOCAL_LOGV) {
Log.v(LOG_TAG, "parse: MESSAGE_TYPE_RETRIEVE_CONF");
}
RetrieveConf retrieveConf =
new RetrieveConf(mHeaders, mBody);
byte[] contentType = retrieveConf.getContentType();
if (null == contentType) {
if (LOCAL_LOGV)
Log.v(LOG_TAG, "contentType is null");
return null;
}
String ctTypeStr = new String(contentType);
if (LOCAL_LOGV)
Log.v(LOG_TAG, "ctTypeStr is l"+ctTypeStr);
if (ctTypeStr.equals(ContentType.MULTIPART_MIXED)
|| ctTypeStr.equals(ContentType.MULTIPART_RELATED)
|| ctTypeStr.equals(ContentType.TEXT_PLAIN)//这里是加入对“text/plain”格式彩信的兼容
|| ctTypeStr.equals(ContentType.MULTIPART_ALTERNATIVE)) {
// The MMS content type must be "application/vnd.wap.multipart.mixed"
// or "application/vnd.wap.multipart.related"
// or "application/vnd.wap.multipart.alternative"
return retrieveConf;
} else if (ctTypeStr.equals(ContentType.MULTIPART_ALTERNATIVE)) {
// "application/vnd.wap.multipart.alternative"
// should take only the first part.
PduPart firstPart = mBody.getPart(0);
mBody.removeAll();
mBody.addPart(0, firstPart);
return retrieveConf;
}
return null;
以下这发现异常的时候忽视异常：
