我正在尝试制作一个无需使用原生 Android 消息应用程序即可发送彩信的应用程序。我按照这里的例子。我的日志语句似乎可以正确打印,但我不知道为什么没有发送彩信。
另外,我对在示例中选择附件(如图像)作为彩信发送的位置有点困惑。我尝试将演示导入 Android Studio,但遇到了问题。
我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");
}
}
});
}
辅助函数
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);
}
我的清单的相关部分
<uses-permission android:name="android.permission.SEND_SMS" />

<uses-permission android:name="android.permission.WRITE_SMS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
相关实例变量
private final long DEFAULT_EXPIRY_TIME = 7 * 24 * 60 * 60;
private final String TEXT_PART_FILENAME = "text_0.txt";
private final int DEFAULT_PRIORITY = PduHeaders.PRIORITY_NORMAL;
private String mMessage;
private ArrayList<String> mDestList;
private Context mContext;
private static final String sSmilText =
"<smil>" +
"<head>" +
"<layout>" +
"<root-layout/>" +
"<region height=\"100%%\" id=\"Text\" left=\"0%%\" top=\"0%%\" width=\"100%%\"/>" +
"</layout>" +
"</head>" +
"<body>" +
"<par dur=\"8000ms\">" +
"<text src=\"%s\" region=\"Text\"/>" +
"</par>" +
"</body>" +
"</smil>";
我已经进行了输入检查,所以在调用 sendMMS() 时,我的 message 和 destList 不为空。
