Android中的SMS原始pdu

1）有什么方法可以从Android设备发送原始SMS PDU？

要么，

2）是否有可用的类可以使我访问PDU标头（例如TP-DCS），以便我可以按自己的喜好构造PDU？

我已经在网上搜索并发现：http

//www.androidjavadoc.com/1.0_r1_src/com/android/internal/telephony/gsm/ISms.html，

但以上类是私有的，因此对我不可用（避难所）实际上不明白为什么）。

我要问的内容是否有可能？如果不是，那我为什么不能拥有这种功能？

谢谢

回答：

这是公共API所要求的功能。

开发人员的注释暗示了使用sendRawPdu内部SMSDispatcherAPI的，可以通过反射来完成。但是，强烈建议不要将私有API用于生产代码

尚不清楚是否可以使用公共TelephonyManagerAPI 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.
