 /**
  * The Telephony provider contains data related to phone operation, specifically SMS and MMS
  * messages, access to the APN list, including the MMSC to use, and the service state.
  *
  * <p class="note"><strong>Note:</strong> These APIs are not available on all Android-powered
  * devices. If your app depends on telephony features such as for managing SMS messages, include
  * a <a href="{@docRoot}guide/topics/manifest/uses-feature-element.html">{@code <uses-feature>}
  * </a> element in your manifest that declares the {@code "android.hardware.telephony"} hardware
  * feature. Alternatively, you can check for telephony availability at runtime using either
  * {@link android.content.pm.PackageManager#hasSystemFeature
  * hasSystemFeature(PackageManager.FEATURE_TELEPHONY)} or {@link
  * android.telephony.TelephonyManager#getPhoneType}.</p>
  *
  * <h3>Creating an SMS app</h3>
  *
  * <p>Only the default SMS app (selected by the user in system settings) is able to write to the
  * SMS Provider (the tables defined within the {@code Telephony} class) and only the default SMS
  * app receives the {@link android.provider.Telephony.Sms.Intents#SMS_DELIVER_ACTION} broadcast
  * when the user receives an SMS or the {@link
  * android.provider.Telephony.Sms.Intents#WAP_PUSH_DELIVER_ACTION} broadcast when the user
  * receives an MMS.</p>
  *
  * <p>Any app that wants to behave as the user's default SMS app must handle the following intents:
  * <ul>
  * <li>In a broadcast receiver, include an intent filter for {@link Sms.Intents#SMS_DELIVER_ACTION}
  * (<code>"android.provider.Telephony.SMS_DELIVER"</code>). The broadcast receiver must also
  * require the {@link android.Manifest.permission#BROADCAST_SMS} permission.
  * <p>This allows your app to directly receive incoming SMS messages.</p></li>
  * <li>In a broadcast receiver, include an intent filter for {@link
  * Sms.Intents#WAP_PUSH_DELIVER_ACTION}} ({@code "android.provider.Telephony.WAP_PUSH_DELIVER"})
  * with the MIME type <code>"application/vnd.wap.mms-message"</code>.
  * The broadcast receiver must also require the {@link
  * android.Manifest.permission#BROADCAST_WAP_PUSH} permission.
  * <p>This allows your app to directly receive incoming MMS messages.</p></li>
  * <li>In your activity that delivers new messages, include an intent filter for
  * {@link android.content.Intent#ACTION_SENDTO} (<code>"android.intent.action.SENDTO"
  * </code>) with schemas, <code>sms:</code>, <code>smsto:</code>, <code>mms:</code>, and
  * <code>mmsto:</code>.
  * <p>This allows your app to receive intents from other apps that want to deliver a
  * message.</p></li>
  * <li>In a service, include an intent filter for {@link
  * android.telephony.TelephonyManager#ACTION_RESPOND_VIA_MESSAGE}
  * (<code>"android.intent.action.RESPOND_VIA_MESSAGE"</code>) with schemas,
  * <code>sms:</code>, <code>smsto:</code>, <code>mms:</code>, and <code>mmsto:</code>.
  * This service must also require the {@link
  * android.Manifest.permission#SEND_RESPOND_VIA_MESSAGE} permission.
  * <p>This allows users to respond to incoming phone calls with an immediate text message
  * using your app.</p></li>
  * </ul>
  *
  * <p>Other apps that are not selected as the default SMS app can only <em>read</em> the SMS
  * Provider, but may also be notified when a new SMS arrives by listening for the {@link
  * Sms.Intents#SMS_RECEIVED_ACTION}
  * broadcast, which is a non-abortable broadcast that may be delivered to multiple apps. This
  * broadcast is intended for apps that&mdash;while not selected as the default SMS app&mdash;need to
  * read special incoming messages such as to perform phone number verification.</p>
  *
  * <p>For more information about building SMS apps, read the blog post, <a
  * href="http://android-developers.blogspot.com/2013/10/getting-your-sms-apps-ready-for-kitkat.html"
