+<p>Provides classes which allow applications to use Wi-Fi Aware to discover peers and create
+    connections to them.</p>
+<p>Using the Wi-Fi Aware APIs, applications can advertise services, discover peers which are
+    advertising services, and connect to them.
+    Wi-Fi Aware is independent of Wi-Fi infrastructure (i.e. a device may or may
+    not be associated with an AP concurrent to using Wi-Fi Aware). </p>
+<p>The primary entry point to Wi-Fi Aware capabilities is the
+    {@link android.net.wifi.aware.WifiAwareManager} class, which is acquired by calling
+    {@link android.content.Context#getSystemService(String)
+    Context.getSystemService(Context.WIFI_AWARE_SERVICE)}</p>
+
+<p>Some APIs may require the following user permissions:</p>
+<ul>
+    <li>{@link android.Manifest.permission#ACCESS_WIFI_STATE}</li>
+    <li>{@link android.Manifest.permission#CHANGE_WIFI_STATE}</li>
+    <li>{@link android.Manifest.permission#ACCESS_COARSE_LOCATION}</li>
+</ul>
+
+<p class="note"><strong>Note:</strong> Not all Android-powered devices support Wi-Fi Aware
+    functionality.
+    If your application only works with Wi-Fi Aware (i.e. it should only be installed on devices which
+    support Wi-Fi Aware), declare so with a <a
+            href="{@docRoot}guide/topics/manifest/uses-feature-element.html">

+<p>Alternatively, if you application does not require Wi-Fi Aware but can take advantage of it if
+    available, you can perform
+    the check at run-time in your code using {@link

-<HTML>
-<BODY>
-<p>Provides classes which allow applications to use Wi-Fi NAN to discover peers and create
-    connections to them.</p>
-<p>Using the Wi-Fi NAN APIs, applications can advertise services, discover peers which are
-    advertising services, and connect to them.
-    Wi-Fi NAN is independent of Wi-Fi infrastructure (i.e. a device may or may
-    not be associated with an AP concurrent to using Wi-Fi NAN). </p>
-<p>The primary entry point to Wi-Fi NAN capabilities is the
-    {@link android.net.wifi.nan.WifiNanManager} class, which is acquired by calling
-    {@link android.content.Context#getSystemService(String)
-    Context.getSystemService(Context.WIFI_NAN_SERVICE)}</p>
-
-<p>Some APIs may require the following user permissions:</p>
-<ul>
-    <li>{@link android.Manifest.permission#ACCESS_WIFI_STATE}</li>
-    <li>{@link android.Manifest.permission#CHANGE_WIFI_STATE}</li>
-    <li>{@link android.Manifest.permission#ACCESS_COARSE_LOCATION}</li>
-</ul>
-
-<p class="note"><strong>Note:</strong> Not all Android-powered devices support Wi-Fi NAN
-    functionality.
-    If your application only works with Wi-Fi NAN (i.e. it should only be installed on devices which
-    support Wi-Fi NAN), declare so with a <a
-            href="{@docRoot}guide/topics/manifest/uses-feature-element.html">
-        {@code &lt;uses-feature&gt;}</a>
-    element in the manifest file:</p>
-<pre>
-&lt;manifest ...>
-    &lt;uses-feature android:name="android.hardware.wifi.nan" />
-    ...
-&lt;/manifest>
-</pre>
-<p>Alternatively, if you application does not require Wi-Fi NAN but can take advantage of it if
-    available, you can perform
-    the check at run-time in your code using {@link
-    android.content.pm.PackageManager#hasSystemFeature(String)} with {@link
-    android.content.pm.PackageManager#FEATURE_WIFI_NAN}:</p>
