The document discusses messaging in Android applications. It provides code samples for sending SMS programmatically using intents and receiving SMS broadcasts. It notes that messages sent programmatically won't appear in the default messaging app and that setting android:priority to 1000 ensures your app receives broadcasts first. The document also covers testing SMS on emulators and required permissions.

i.putExtra("sms_body", "Hello i love recursion!");
i.setType("vnd.android-dir/mms-sms");

10. SMS Testing on Emulator

11. At last I did
something cool
with emulator

12. <uses-feature
android:name=”android.hardware.telephony”
android:required=”true”/>
Marking telephony as a required feature prevents your
application from being found on Google Play using a device
without telephony hardware support
Other permission needed for SMS Application
<uses-permission android:name="android.permission.SEND_SMS" >
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS" >
</uses-permission>
