无法使用SmsManager发送彩信

标签: android android-mms

我正在尝试使用原生Android消息应用制作一个不使用发送彩信的应用。我按照示例here进行了操作。我的日志声明似乎正确打印,但我无法弄清楚为什么没有发送彩信。

另外,在另一个注释中,我有点困惑的是,在示例中,附件(如图像)被选择作为MMS发送。我试图将演示版导入Android Studio,但我遇到了问题。

发送彩信的功能如下:

 public void sendMMS() {
    Log.d(TAG, "sendMMS()");
    Random random = new Random();
    final String fileName = "send." + String.valueOf(Math.abs(random.nextLong())) + ".dat";

    final File mSendFile = new File(mContext.getCacheDir(), fileName);
    // Making RPC call in non-UI thread
    AsyncTask.THREAD_POOL_EXECUTOR.execute(new Runnable() {
        @Override
        public void run() {
            final byte[] pdu = buildPdu();
            Uri writerUri = (new Uri.Builder())
                    .authority("com.example.appname")
                    .path(fileName)
                    .scheme(ContentResolver.SCHEME_CONTENT)
                    .build();
            Log.d(TAG, "sendMMS(): Uri: " + writerUri.toString());
            FileOutputStream writer = null;
            Uri contentUri = null;
            try {
                writer = new FileOutputStream(mSendFile);
                writer.write(pdu);
                contentUri = writerUri;
                Log.d(TAG, "sendMMS(): just wrote file");
            } catch (final IOException e) {
                Log.d(TAG, "sendMMS(): FAILED: couldn't write file");
            } finally {
                if (writer != null) {
                    try {
                        writer.close();
                    } catch (IOException e) {
                    }
                }
            }
            if (contentUri != null) {
                SmsManager.getDefault().sendMultimediaMessage(mContext, contentUri, null, null, null);
                Log.d(TAG, "sendMMS(): just sent");
            } else {
                Log.d(TAG, "sendMMS(): FAILED: couldn't write file so didn't send");
            }
        }
    });

}

帮助程序功能

    private byte[] buildPdu() {
    final SendReq req = new SendReq();
    // from
    final String lineNumber = getSimNumber();
    if (!TextUtils.isEmpty(lineNumber)) {
        req.setFrom(new EncodedStringValue(lineNumber));
    }
    // to
    String[] destsArray = mDestList.toArray(new String[mDestList.size()]);
    EncodedStringValue[] encodedNumbers = EncodedStringValue.encodeStrings(destsArray);
    if (encodedNumbers != null) {
        req.setTo(encodedNumbers);
    }
    // date
    req.setDate(System.currentTimeMillis() / 1000);
    // body
    PduBody body = new PduBody();
    // message text
    final int size = addMessagePart(body, true/* add text smil */);
    req.setBody(body);
    // message size
    req.setMessageSize(size);
    // message class
    req.setMessageClass(PduHeaders.MESSAGE_CLASS_PERSONAL_STR.getBytes());
    // expiry
    req.setExpiry(DEFAULT_EXPIRY_TIME);
    try {
        // priority
        req.setPriority(DEFAULT_PRIORITY);
        // delivery report
        req.setDeliveryReport(PduHeaders.VALUE_NO);
        // read report
        req.setReadReport(PduHeaders.VALUE_NO);
    } catch (InvalidHeaderValueException e) {}
    return new PduComposer(mContext, req).make();
}

private String getSimNumber() {
    TelephonyManager telephonyManager = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);
    return telephonyManager.getLine1Number();
}

private int addMessagePart(PduBody pb, boolean addTextSmil) {
    PduPart part = new PduPart();
    part.setCharset(CharacterSets.UTF_8);
    part.setContentType(ContentType.TEXT_PLAIN.getBytes());
    part.setContentLocation(TEXT_PART_FILENAME.getBytes());
    int index = TEXT_PART_FILENAME.lastIndexOf(".");
    String contentId = (index == -1) ? TEXT_PART_FILENAME : TEXT_PART_FILENAME.substring(0, index);
    part.setContentId(contentId.getBytes());
    part.setData(mMessage.getBytes());
    pb.addPart(part);
    if (addTextSmil) {
        String smil = String.format(sSmilText, TEXT_PART_FILENAME);
        addSmilPart(pb, smil);
    }
    return part.getData().length;

}

private void addSmilPart(PduBody pb, String smil) {
    PduPart smilPart = new PduPart();
    smilPart.setContentId("smil".getBytes());
    smilPart.setContentType(ContentType.APP_SMIL.getBytes());
    smilPart.setContentLocation("smil.xml".getBytes());
    smilPart.setData(smil.getBytes());
    pb.addPart(0, smilPart);
}

我已经进行了输入检查,所以当调用sendMMS()时,我的消息和destList不为空。

答案 0 :(得分:2)

流程应如此:

  1. 创建Mms发送请求 - new SendReq()并将其日期,正文,配置等等。
  2. 创建Mms正文 - new PduBody()
  3. 为每个附件通过new PduPart()创建零件,然后添加到正文:body.addPart(pdu)
  4. 将正文添加到请求中 - req.setBody(body)
  5. 通过调用new PduComposer(context, mySendReq).make()将发送请求转换为准备发送的byte [] - 请注意,您需要从Android的源代码中复制大量代码才能获得PduComposer类。
  6. 现在是有趣的部分 - 您将byte []保存到您的应用只能访问的本地文件,并添加ContentProvider类,允许其他应用请求访问您的文件,这是MmsFileProvider在示例应用程序中的类,不要忘记在清单文件中声明您的提供程序。
  7. 现在,当您调用SmsManager.sendMultimediaMessage api时,您的文件提供程序将被唤醒以将包含pdu字节的文件提供给系统SmsManager,该系统将读取它并通过网络发送它。
  8. 话虽如此,这个API仅适用于某些设备(例如Nexuses),但不适用于其他设备(例如HTC One)。 在这里看到我的问题: SmsManager MMS APIs on HTC/LG
