Android 中的短信原始 pdu

Question

1) 有什么方法可以从 Android 设备发送原始 SMS PDU？

或者，

2) 是否有任何可用的类可以让我访问 PDU 标头（例如 TP-DCS），以便我可以按照自己的喜好构造 PDU？

我在网上搜索了一下，发现： http://www.androidjavadoc.com/1.0 _r1_src/com/android/internal/telephony/gsm/ISms.html 但上述课程是私有的，因此我无法使用（实际上还没有理解为什么）。

我所问的是否可能？如果没有的话为什么我不能拥有这种功能呢？

谢谢

Answer 1

我知道怎么做。 http://www.silentservices.de/products/android-hushsms/ 和 <代码>xpose框架 http://repo.xposed.info /module/de.robv.android.xposed.installer
您需要 root 手机才能使用 xposed 模块“raw-pdu”，但它可以工作。 Hush-sms 提供 API 功能/可扩展性来发送 7 种原始短信类型。

Answer 2

这是公共 API 的请求的功能。

开发人员评论暗示使用内部 SMSDispatcher API 中的 sendRawPdu，这可以通过

尚不清楚是否可以使用公共 TelephonyManager API 进行发送。

/*
 * TODO(cleanup): It looks like there is now no useful reason why
 * apps should generate pdus themselves using these routines,
 * instead of handing the raw data to SMSDispatcher (and thereby
 * have the phone process do the encoding).  Moreover, CDMA now
 * has shared state (in the form of the msgId system property)
 * which can only be modified by the phone process, and hence
 * makes the output of these routines incorrect.  Since they now
 * serve no purpose, they should probably just return null
 * directly, and be deprecated.  Going further in that direction,
 * the above parsers of serialized pdu data should probably also
 * be gotten rid of, hiding all but the necessarily visible
 * structured data from client apps.  A possible concern with
 * doing this is that apps may be using these routines to generate
 * pdus that are then sent elsewhere, some network server, for
 * example, and that always returning null would thereby break
 * otherwise useful apps.

public static SubmitPdu getSubmitPdu(String scAddress,
        String destinationAddress, String message,
        boolean statusReportRequested, byte[] header) {

综上所述：
目前尚不清楚是否可能。我和你有同样的问题。
