+            \"Immersive Mode\" is a new UI mode which improves \"hide full screen\" and

+            \n\nThis sample also lets the user choose between normal immersive mode and "sticky"
+            immersive mode, which removes the status bar and nav bar
+            a few seconds after the user has swiped them back in.

+ *
+ * When launched under the primary User account, you can toggle between standard app restriction
+ * types and custom.  When launched under a restricted profile, this activity displays app
+ * restriction settings, if available.
+ *
+ * Follow these steps to exercise the feature:
+ * 1. If this is the primary user, go to Settings > Users.
+ * 2. Create a restricted profile, if one doesn't exist already.
+ * 3. Open the profile settings, locate the sample app, and tap the app restriction settings
+ *    icon. Configure app restrictions for the app.
+ * 4. In the lock screen, switch to the user's restricted profile, launch this sample app,
+ *    and see the configured app restrictions displayed.

+        Tap the button below to send a notification.\n\nThe notification\'s icon will immediately
+        appear in the notification bar. Drag the notification bar open to see the full
+        notification. Depending on which version of Android you\'re running, the full
+        notification will display an icon and two or three lines of text.
+        \n\nTap the notification to execute the notification\'s \"action,\" which is an intent
+        that we associate with the notification when it\'s created. This sample notification\'s
+        action is to send a browse intent with the url of the Notification docs on
+        developer.android.com.
+        \n\nThis sample uses the NotificationCompat API for maximum compatibility with versions
+        of Android from Froyo (Android 2.2) to the present. Try it on devices or AVDs that are
+        running different versions of Android. You\'ll see that while the presentation varies
+        slightly, the basic functionality is the same. NotificationCompat automatically takes
+        advantage of the expanded notification format in newer versions of Android, and
+        falls back gracefully to a reduced set of functionality on earlier versions.

+/**
+ * Helper for building selection clauses for {@link SQLiteDatabase}.
+ *
+ * <p>This class provides a convenient frontend for working with SQL. Instead of composing statements
+ * manually using string concatenation, method calls are used to construct the statement one
+ * clause at a time. These methods can be chained together.
+ *
+ * <p>If multiple where() statements are provided, they're combined using {@code AND}.
+ *
+ * <p>Example:
+ *
+ * <pre>
+ *     SelectionBuilder builder = new SelectionBuilder();
+ *     Cursor c = builder.table(FeedContract.Entry.TABLE_NAME)       // String TABLE_NAME = "entry"
+ *                       .where(FeedContract.Entry._ID + "=?", id);  // String _ID = "_ID"
+ *                       .query(db, projection, sortOrder)
+ *
+ * </pre>
+ *
+ * <p>In this example, the table name and filters ({@code WHERE} clauses) are both explicitly
+ * specified via method call. SelectionBuilder takes care of issuing a "query" command to the
+ * database, and returns the resulting {@link Cursor} object.
+ *
+ * <p>Inner {@code JOIN}s can be accomplished using the mapToTable() function. The map() function
+ * can be used to create new columns based on arbitrary (SQL-based) criteria. In advanced usage,
+ * entire subqueries can be passed into the map() function.
+ *
+ * <p>Advanced example:
+ *
+ * <pre>
+ *     // String SESSIONS_JOIN_BLOCKS_ROOMS = "sessions "
+ *     //        + "LEFT OUTER JOIN blocks ON sessions.block_id=blocks.block_id "
+ *     //        + "LEFT OUTER JOIN rooms ON sessions.room_id=rooms.room_id";
+ *
+ *     // String Subquery.BLOCK_NUM_STARRED_SESSIONS =
+ *     //       "(SELECT COUNT(1) FROM "
+ *     //        + Tables.SESSIONS + " WHERE " + Qualified.SESSIONS_BLOCK_ID + "="
+ *     //        + Qualified.BLOCKS_BLOCK_ID + " AND " + Qualified.SESSIONS_STARRED + "=1)";
+ *
+ *     String Subqery.BLOCK_SESSIONS_COUNT =
+ *     Cursor c = builder.table(Tables.SESSIONS_JOIN_BLOCKS_ROOMS)
+ *               .map(Blocks.NUM_STARRED_SESSIONS, Subquery.BLOCK_NUM_STARRED_SESSIONS)
+ *               .mapToTable(Sessions._ID, Tables.SESSIONS)
+ *               .mapToTable(Sessions.SESSION_ID, Tables.SESSIONS)
+ *               .mapToTable(Sessions.BLOCK_ID, Tables.SESSIONS)
+ *               .mapToTable(Sessions.ROOM_ID, Tables.SESSIONS)
+ *               .where(Qualified.SESSIONS_BLOCK_ID + "=?", blockId);
+ * </pre>
+ *
+ * <p>In this example, we have two different types of {@code JOIN}s: a left outer join using a
+ * modified table name (since this class doesn't directly support these), and an inner join using
+ * the mapToTable() function. The map() function is used to insert a count based on specific
+ * criteria, executed as a sub-query.
+ *
+ * This class is <em>not</em> thread safe.

+            This sample demonstrates the use of the two step sensors (step detector and counter) and
+            sensor batching.\n\n It shows how to register a SensorEventListener with and without
+            batching and shows how these events are received.\n\nThe Step Detector sensor fires an
+            event when a step is detected, while the step counter returns the total number of
+            steps since a listener was first registered for this sensor.
+            Both sensors only count steps while a listener is registered. This sample only covers the
+            basic case, where a listener is only registered while the app is running. Likewise,
+            batched sensors can be used in the background (when the CPU is suspended), which
+            requires manually flushing the sensor event queue before it overflows, which is not
+            covered in this sample.

+            feature added in Android 4.4. This sample makes the device appear as a loyalty card

+            NFC reader.
+
+            The "CardReader" sample can be used to read the loyalty card implemented in this sample.

+     Vendor-specific AIDs should always start with an "F", according to the ISO 7816 spec. We
+     recommended vendor-specific AIDs be at least 6 characters long, to provide sufficient
+     uniqueness. Note, however, that longer AIDs may impose a burden on non-Android NFC terminals.
+     AIDs may not exceed 32 characters (16 bytes).
+
+     Additionally, AIDs must always contain an even number of characters, in hexadecimal format.
+
+     In order to avoid prompting the user to select which service they want to use when the device
+     is scanned, this app must be selected as the default handler for an AID group by the user, or
+     the terminal must select *all* AIDs defined in the category simultaneously ("exact match").

+    If category="payment" is used for any aid-groups, you must also add an android:apduServiceBanner
+    attribute above, like so:
+
+    android:apduServiceBanner="@drawable/settings_banner"
+
+     apduServiceBanner should be 260x96 dp. In pixels, that works out to...
+       - drawable-xxhdpi: 780x288 px
+       - drawable-xhdpi:  520x192 px

+
+    The apduServiceBanner is displayed in the "Tap & Pay" menu in the system Settings app, and
+    is only displayed for apps which implement the "payment" AID category.
+
+    Since this sample is implementing a non-standard card type (a loyalty card, specifically), we
+    do not need to define a banner.
+
+    Important: category="payment" should only be used for industry-standard payment cards. If you are
+        implementing a closed-loop payment system (e.g. stored value cards for a specific merchant
+        or transit system), use category="other". This is because only one "payment" card may be
+        active at a time, whereas all "other" cards are active simultaneously (subject to AID
+        dispatch).

+                This sample demonstrates two alternative presentations of the
+                action bar that are well-suited for simple data entry scenarios.
+
+                In this presentation, a done bar replaces the action
+                bar entirely, providing two direct actions to persist or dismiss changes. This is
+                suitable for cases where no additional view details or actions are needed in the
+                action bar.
