If you read <a href="http://www.mail-archive.com/android-developers@googlegroups.com/msg11410.html" rel="nofollow noreferrer">this</a> post from the android-developer mailing list you can see that <code>android.provider.Telephony</code> is part of the Open Source releases, but never included as part of the Official SDK.

Meaning you are free to view it, to gain a understanding of how the underlying system works, but you can't actually reference and compile against it in your Android application(s).

Thanks Brian, however, it seems Telephony is used by code posted on <a href="http://www.anddev.org/recognize-react_on_incoming_sms-t295.html" rel="nofollow noreferrer">this site</a>.

In this excerpt from Apress (ISBN: 978-1-43021-064-1) by Chris Haseman, it is used too:

<blockquote>
 Telephony class is used for sms messaging, 

<pre><code>(Context context, Intent intent)
{
SmsMessage msg[] =
 Telephony.Sms.Intents.getMessagesFromIntent(intent);
...
</code></pre>
</blockquote>

blocks|key|104872|text|你在anddev.org上链接的代码是SDK版本m5-rc14的代码，它来自2008年2月，几乎有一整年的历史了。当前SDK版本为1.0，与m5-rc14之间有两个版本。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|104873|鉴于Android项目的性质，他们在其快速增长/采用的过程中添加和删除了许多接口。许多人抱怨说，他们正在关闭操作系统的一些很酷的部分的接口，例如电话接口。|104874|您可以查看android.telephony+(link)包，并查看其中是否有等效的功能。|104875|entityMap|0|LINK|mutability|MUTABLE|url|http://code.google.com/android/reference/android/telephony/package-summary.html^0|O|7|0|0|O|4|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|V|8|@]|D|@$9|W|A|X|1|Y]]|E|$]]|$1|J|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]]]

The code you linked to on anddev.org is for SDK version m5-rc14 which is from February, 2008 almost an entire year old. The current SDK version is 1.0, with two releases between it and m5-rc14.

Given the nature of the Android project they have added and removed many interfaces in its rapid growth/adoption. A lot of people have complained that they are closing out some of the interfaces to some cool parts of the operating system, such as the Telephony interface. 

You can check out android.telephony (<a href="http://code.google.com/android/reference/android/telephony/package-summary.html" rel="nofollow noreferrer">link</a>) package and see if there is equivalent functionality there.

blocks|key|2009913|text|您还可以使用它从当前接收信号中获取数据。检查this+tutorial-它使用电话管理器来获取数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2009914|entityMap|0|LINK|mutability|MUTABLE|url|http://www.firstdroid.com/2010/05/12/get-provider-gsm-signal-strength/^0|M|D|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You can also use it to get data from your current reception signal.
Check <a href="http://www.firstdroid.com/2010/05/12/get-provider-gsm-signal-strength/" rel="nofollow noreferrer">this tutorial</a>- it uses the telephony manager to get data.

blocks|key|4901667|text|我可以使用下面的库使用G1发送短信:+android.telephony.gsm.SmsManager|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4901668|因此，至少(对于SMS发送/接收代码)有一个等效的库可用。|4901669|另外，请务必查看TelephonyManager+http://code.google.com/android/reference/android/telephony/TelephonyManager.html|offset|length|4901670|这并不完全是你想要的，但它确实提供了很多你正在寻找的功能。|4901671|至于上面答案中的APress书籍参考，我写了它。到目前为止，它有点过时了(它是在1.0+SDK发布之前发布的)，我几乎完成了更新。啊哈，快速更新技术的乐趣。|4901672|entityMap|0|LINK|mutability|MUTABLE|url|http://code.google.com/android/reference/android/telephony/TelephonyManager.html^0|0|0|P|28|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@$F|W|G|X|1|Y]]|A|$]]|$1|H|3|I|5|6|7|Z|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|10|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S]]]]

I was able to send an SMS message with the G1 using the following library:
android.telephony.gsm.SmsManager

So at least (for the SMS send/receive code) there is an equivalent library available.

Also be sure to check out the TelephonyManager
<a href="http://code.google.com/android/reference/android/telephony/TelephonyManager.html" rel="nofollow noreferrer">http://code.google.com/android/reference/android/telephony/TelephonyManager.html</a>

This isn't exactly what you were asking about, but it does provide a lot of the functionality you're looking for.

As for the APress book reference in the answer above, I wrote it. As of right now, it's a little out of date (It was published before the 1.0 SDK was published) and I'm almost done updating it. Ahhh the joys of rapidly updating technology.

Does anyone know what happened to <code>android.provider.Telephony</code>? It is not there anymore.
