java - Android 中的 SMS 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 header (例如 TP-DCS)，以便我可以根据需要构建 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但是上面的类是私有(private)的，因此我无法使用(实际上还不明白为什么)。

我所问的是否可能？如果没有，那为什么我不能拥有那种功能？

谢谢

Answer 1

这是一个 requested公共(public) API 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 reflection 完成.但是，强烈建议不要将私有(private) API 用于生产代码

尚不清楚是否可以使用公共(public) 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.

 *         address, if applicable, and the encoded message.

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

总结:目前尚不清楚这是否可能。我和你有同样的问题。
