  Wearable drawers

</h4>

<p>

  This Developer Preview release is for app developers only and is designed for

  use in compatibility testing and early development only.

  The following are feature additions for <a href=

  "{@docRoot}wear/preview/features/ui-nav-actions.html">

  wearable drawers</a>:

</p>

<h4 id="deprecations">Deprecations</h4>

<ul>

  <li>Drawer peeking is now supported in the <code>onCreate()</code> method

  of your app's activity.

  </li>

  <li>The automatic drawer peeking behavior is

  inverted. Now the bottom drawer peeks when the user scrolls down the view

  and top drawer peeks when the user scrolls to the top of the view

  (previously scrolling down did not show peek view).

  </li>

<p>The following fields are deprecated in the Preview:</p>

  <li>Two new attributes, <code>peek_view</code> and

  <code>drawer_content</code>, are added to

  <code>WearableDrawerView</code> to specify contents of custom drawers and

  peek view in your XML layout (previously, custom drawer contents were

  specified only through Java code).

  </li>

  <li>The Navigation drawer now displays page indicator dots.

  </li>

  <li>Peek views now close automatically after one second.

  </li>

  <li>The <code>WearableNavigationDrawer</code> now automatically closes

  after five seconds or when an item is tapped.

  </li>

  <li>There is improved drawer handling (size and margins) for devices with chins:

    <ul>

  <li>The <code>Notification.WearableExtender#setCustomSizePreset(int)</code>

  method no longer accepts <code>SIZE_FULL_SCREEN</code> and this value is now

  undefined.

      <li>Size: The bottom drawer is slightly smaller when there is a

      chin.

      </li>

      <li>Margins: <code>WearableDrawerLayout</code> sets its bottom margin

      size equal to the size of the chin, so that the bottom drawer is

      fully visible.

      </li>

    </ul>

  <li>The navigation drawer contents are now updated when

        <code><a href="{@docRoot}reference/android/widget/ArrayAdapter.html#notifyDataSetChanged()">

        notifyDataSetChanged</a></code> is called on the adapter.

  </li>

  <li>The <code>Notification.WearableExtender#setContentIcon(int)</code> method

  is deprecated.

    <li>In your <code>WearableActionDrawer</code>, when there is only one

      action, its icon is shown in the peek view and the action is executed

      when the peek view is tapped.

    </li>

    <li>When the peek view of your <code>WearableActionDrawer</code> has

      more than one action, both the first action and the overflow icons are

      shown.

    </li>

</ul>

  Wrist gestures can enable quick, one-handed interactions with your app.

  scroll through notifications with one hand while holding a cup of water

  with the other. For more information, see <a href=
