<p>Fixed issues:</p>
<ul>
<li>Fixes an issue in the 24.1.0 release which affected resource IDs
shared between support libraries. This issue caused apps that depended on
support libraries with resources (such as design and appcompat) to
encounter issues caused by resource ID mismatches.

<ul>
<li>{@link android.support.v4.app.NotificationCompat.Action.WearableExtender}
has new <code>getHintDisplayActionInline()</code> and
<code>setHintDisplayActionInline()</code> methods for compatibility with
<a href="{@docRoot}wear/preview/index.html">Android Wear 2.0 Preview</a>.
These methods allow an application to specify that an action should be
displayed inline with the notification.
</li>
<li>Calling {@link android.support.v4.app.Fragment#setUserVisibleHint
Fragment.setUserVisbileHint()} will no longer cause a fragment to become
<strong>started</strong> if the hint has been added to a {@link
android.support.v4.app.FragmentTransaction} that is not yet committed. This
affects users of {@link android.support.v4.app.FragmentPagerAdapter} that
override {@link android.support.v4.app.Fragment#setUserVisibleHint
setUserVisbileHint()} and assume a specific lifecycle state of the fragment
after calling <code>super.setUserVisibleHint()</code>. For more information,
see the reference page for docs for {@link
android.support.v4.app.Fragment#setUserVisibleHint
Fragment.setUserVisbileHint()}.

<dd>
<ul>
<li>Added {@link android.support.v4.app.ShareCompat}, which provides helper classes
for sending and receiving content for social sharing applications, including new metadata for
attributing shared data to the source app. This class also provides compatible integration with the
new {@link android.widget.ShareActionProvider} in Android 4.0.</li>
<li>Added {@link android.support.v4.app.NavUtils} and {@link
android.support.v4.app.TaskStackBuilder} to provide support for implementing the
<a href="{@docRoot}design/index.html">Android Design</a> guidelines for navigation. These
additions include a way to implement the action bar's <em>Up</em> button across versions.
For an example implementation of this pattern, see the AppNavigation sample in
({@code <em><sdk></em>/samples/<em><platform></em>/AppNavigation}).</li>
<li>Added {@link android.support.v4.app.NotificationCompat.Builder} to provide a
compatibility implementation of Android 3.0's {@link android.app.Notification.Builder} helper class
for creating standardized system notifications.</li>

<li>All new APIs (available only in the support library) that allow you to create UIs
with horizontal paging, allowing users to swipe left and right between content views. Classes to
support this include:
<ul>
<li>{@code ViewPager}: A {@link android.view.ViewGroup} that manages the
layout for the child views, which the user can swipe between.</li>
<li>{@code PagerAdapter}: An adapter that populates the {@code ViewPager} with the
views that represent each page.</li>
<li>{@code FragmentPagerAdapter}: An extension of {@code PagerAdapter} for flipping
between fragments.</li>
<li>{@code FragmentStatePagerAdapter}: An extension of {@code PagerAdapter} for
flipping between fragments that uses the library's support for {@link
android.app.Fragment.SavedState}.</li>

<dt>New v13 support library:</dt>
<dd>
<ul>
<li>Includes the {@code FragmentPagerAdapter} and {@code FragmentStatePagerAdapter}
to support the horizontal paging.
<p>These are exactly the same as the APIs added to the v4 support library, but rely on
other platform components in Android 3.2. Use this library instead of v4 if you're developing for
Android 3.2 and higher (all other APIs in the v4 library are already available with API level
13).</p>
