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;
