too*_*o42 15 api service android mms android-4.4-kitkat
所以来自#DevBytes的这个视频Android 4.4 SMS API解释了KitKat中SMS API的最新变化.它们还提供了与示例项目的链接.http://goo.gl/uQ3Nih
他们建议您处理服务中的MMS接收.这一切看起来都很好,除了他们忽略了提到最无证件.如何实际处理传入的MMS.
以下是项目https://gist.github.com/lawloretienne/8970938的示例
我试过"处理彩信"

我可以从意图中获取额外内容,但我能提取的唯一有意义的事情是发送MMS的号码.
任何人都可以指出我正确的方向如何去做这个？
我注意到WAP_PUSH_MESSAGE包含一些东西,FROM,SUBJECT和CONTENT_LOCATION.
内容位置似乎是包含MMS内容的URL.我该如何访问？
以下是该URL的示例
https://atl1mmsget.msg.eng.t-mobile.com/mms/wapenc?location=XXXXXXXXXXX_14zbwk&rid=027
其中X是我正在测试的设备的电话号码中的数字.
它看起来像美国的T-Mobile的MMSC(多媒体消息服务中心) http://mms.msg.eng.t-mobile.com/mms/wapenc

没有文档,所以这里有一些信息可以提供帮助.
1)来自源的com.google.android.mms.pdu.你需要Pdu工具.
2)您从传入的mms广播的字节数组中获取通知推送(intent.getByteArrayExtra("data")).
3)将通知推送解析为GenericPdu(新的PduParser(rawPdu).parse()).
4)您需要TransactionSettings与运营商的WAP服务器进行通信.我在下面的#5之后得到了交易设置.我用:
TransactionSettings transactionSettings = new TransactionSettings(mContext, mConnMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE_MMS).getExtraInfo());
5)通过wifi强制网络通信.我使用以下内容.
private boolean beginMmsConnectivity() {
try {
int result = mConnMgr.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, Phone.FEATURE_ENABLE_MMS);
NetworkInfo info = mConnMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE_MMS);
boolean isAvailable = info != null && info.isConnected() && result == Phone.APN_ALREADY_ACTIVE && !Phone.REASON_VOICE_CALL_ENDED.equals(info.getReason());
return isAvailable;
} catch(Exception e) {
return false;
}
}
6)然后,您需要确保到主机的路由.
private static void ensureRouteToHost(ConnectivityManager cm, String url, TransactionSettings settings) throws IOException {
int inetAddr;
if (settings.isProxySet()) {
String proxyAddr = settings.getProxyAddress();
inetAddr = lookupHost(proxyAddr);
if (inetAddr == -1) {
throw new IOException("Cannot establish route for " + url + ": Unknown host");
} else {
if (!cm.requestRouteToHost(ConnectivityManager.TYPE_MOBILE_MMS, inetAddr))
throw new IOException("Cannot establish route to proxy " + inetAddr);
}
} else {
Uri uri = Uri.parse(url);
inetAddr = lookupHost(uri.getHost());
if (inetAddr == -1) {
throw new IOException("Cannot establish route for " + url + ": Unknown host");
} else {
if (!cm.requestRouteToHost(ConnectivityManager.TYPE_MOBILE_MMS, inetAddr))
throw new IOException("Cannot establish route to " + inetAddr + " for " + url);
}
}
}
这是lookupHost方法:
private static int lookupHost(String hostname) {
InetAddress inetAddress;
try {
inetAddress = InetAddress.getByName(hostname);
} catch (UnknownHostException e) {
return -1;
}
byte[] addrBytes;
int addr;
addrBytes = inetAddress.getAddress();
addr = ((addrBytes[3] & 0xff) << 24) | ((addrBytes[2] & 0xff) << 16) | ((addrBytes[1] & 0xff) << 8) | (addrBytes[0] & 0xff);
return addr;
}
我还想使用基于反射的方法来改进ensureRouteToHost功能:
private static void ensureRouteToHostFancy(ConnectivityManager cm, String url, TransactionSettings settings) throws IOException, NoSuchMethodException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
Method m = cm.getClass().getMethod("requestRouteToHostAddress", new Class[] { int.class, InetAddress.class });
InetAddress inetAddr;
if (settings.isProxySet()) {
String proxyAddr = settings.getProxyAddress();
try {
inetAddr = InetAddress.getByName(proxyAddr);
} catch (UnknownHostException e) {
throw new IOException("Cannot establish route for " + url + ": Unknown proxy " + proxyAddr);
}
if (!(Boolean) m.invoke(cm, new Object[] { ConnectivityManager.TYPE_MOBILE_MMS, inetAddr }))
throw new IOException("Cannot establish route to proxy " + inetAddr);
} else {
Uri uri = Uri.parse(url);
try {
inetAddr = InetAddress.getByName(uri.getHost());
} catch (UnknownHostException e) {
throw new IOException("Cannot establish route for " + url + ": Unknown host");
}
if (!(Boolean) m.invoke(cm, new Object[] { ConnectivityManager.TYPE_MOBILE_MMS, inetAddr }))
throw new IOException("Cannot establish route to " + inetAddr + " for " + url);
}
}
7)确保到主机的路由后,您可以从源代码获取HttpUtls.我使用OkHttp严格修改了我的实现,以改善通信.
byte[] rawPdu = HttpUtils.httpConnection(mContext, mContentLocation, null, HttpUtils.HTTP_GET_METHOD, mTransactionSettings.isProxySet(), mTransactionSettings.getProxyAddress(), mTransactionSettings.getProxyPort());
8)从结果字节数组中使用PduParser来parging GenericPdu.然后你可以提取身体并转换为MultimediaMessagePdu.
9)然后你可以迭代PDU的各个部分.
有许多事情需要考虑使用MMS.我想到的一件事是幻灯片是多么烦人,所以我要做的是检测PDU中是否有超过1个部分,然后我复制标题并创建单独的MultimediaMessagePdu,我将它们分别保存到手机的mms内容提供商.如果您支持群发消息,请不要忘记复制标题.群发消息是另一个故事,因为PDU中的电话号码不能告诉整个故事(MultimediaMessagePdu.mmpdu()).您使用以下代码提取的标题中有更多联系人.
private HashSet<String> getRecipients(GenericPdu pdu) {
PduHeaders header = pdu.getPduHeaders();
HashMap<Integer, EncodedStringValue[]> addressMap = new HashMap<Integer, EncodedStringValue[]>(ADDRESS_FIELDS.length);
for (int addrType : ADDRESS_FIELDS) {
EncodedStringValue[] array = null;
if (addrType == PduHeaders.FROM) {
EncodedStringValue v = header.getEncodedStringValue(addrType);
if (v != null) {
array = new EncodedStringValue[1];
array[0] = v;
}
} else {
array = header.getEncodedStringValues(addrType);
}
addressMap.put(addrType, array);
}
HashSet<String> recipients = new HashSet<String>();
loadRecipients(PduHeaders.FROM, recipients, addressMap, false);
loadRecipients(PduHeaders.TO, recipients, addressMap, true);
return recipients;
}
这是load recipients方法:
private void loadRecipients(int addressType, HashSet<String> recipients, HashMap<Integer, EncodedStringValue[]> addressMap, boolean excludeMyNumber) {
EncodedStringValue[] array = addressMap.get(addressType);
if (array == null) {
return;
}
// If the TO recipients is only a single address, then we can skip loadRecipients when
// we're excluding our own number because we know that address is our own.
if (excludeMyNumber && array.length == 1) {
return;
}
String myNumber = excludeMyNumber ? mTelephonyManager.getLine1Number() : null;
for (EncodedStringValue v : array) {
if (v != null) {
String number = v.getString();
if ((myNumber == null || !PhoneNumberUtils.compare(number, myNumber)) && !recipients.contains(number)) {
// Only add numbers which aren't my own number.
recipients.add(number);
}
}
}
}
以下是迭代MultimediaMessagePdu部分的方法.
private void processPduAttachments() throws Exception {
if (mGenericPdu instanceof MultimediaMessagePdu) {
PduBody body = ((MultimediaMessagePdu) mGenericPdu).getBody();
if (body != null) {
int partsNum = body.getPartsNum();
for (int i = 0; i < partsNum; i++) {
try {
PduPart part = body.getPart(i);
if (part == null || part.getData() == null || part.getContentType() == null || part.getName() == null)
continue;
String partType = new String(part.getContentType());
String partName = new String(part.getName());
Log.d("Part Name: " + partName);
Log.d("Part Type: " + partType);
if (ContentType.isTextType(partType)) {
} else if (ContentType.isImageType(partType)) {
} else if (ContentType.isVideoType(partType)) {
} else if (ContentType.isAudioType(partType)) {
}
} catch (Exception e) {
e.printStackTrace();
// Bad part shouldn't ruin the party for the other parts
}
}
}
} else {
Log.d("Not a MultimediaMessagePdu PDU");
}
}
还有更多的考虑因素,例如动画GIF支持,这是完全可能的:)有些运营商也支持确认报告和传送报告,除非用户真的想要mms传送报告,否则你很可能忽略这些wap通信.
