+
+<p>
+  Revision 23 of the v4 and v13 support libraries provide several new methods
+  for managing permissions. The support library methods work properly on any
+  device that can use those libraries. Thus, if you use the support library
+  methods, you do not need to check whether your app is running on a device
+  with the M Developer Preview. If an app is installed on a device running the
+  M Preview, the support library methods behave the same as their framework
+  equivalents. If the device is running an earlier version of Android, the
+  methods behave appropriately, as described below.
+</p>
+
+<p>
+  The v4 support library provides the following permissions methods:
+</p>
+
+<dl>
+  <dt>
+    <code>ContextCompat.checkSelfPermission()</code>
+  </dt>
+
+  <dd>
+    Returns <code>true</code> if the app has the specified permission, whether
+    or not the device is using the M Preview.
+  </dd>
+
+  <dt>
+    <code>ActivityCompat.requestPermissions()</code>
+  </dt>
+
+  <dd>
+    If the device is not running the M Preview, invokes the callback
+    method in <code>ActivityCompat.OnRequestPermissionsResultCallback</code>.
+    Passes {@link android.content.pm.PackageManager#PERMISSION_GRANTED
+    PERMISSION_GRANTED} if the app already has the specified permission, or
+    {@link android.content.pm.PackageManager#PERMISSION_DENIED
+    PERMISSION_DENIED} if it does not.
+  </dd>
+
+  <dt>
+    <code>ActivityCompat.shouldShowRequestPermissionRationale()</code>
+  </dt>
+
+  <dd>
+    If the device is not running the M Preview, always returns
+    <code>false</code>.
+  </dd>
+</dl>
+
+<p>
+  The v4 support library also contains the <code>PermissionChecker</code>
+  class, which provides several static utility methods for apps that use IPC to
+  provide services for other apps. For example,
+  <code>PermissionChecker.checkCallingPermission()</code> checks whether an IPC
+  made by a particular package has a specified permission.
+</p>
+
+<p class="note">
+  <strong>Note:</strong> If your app acts on behalf of third-party apps to call
+  platform methods that require runtime permissions on behalf of a third-party
+  app, you should use the appropriate <code>PermissionChecker</code> methods to
+  ensure that the other app is allowed to perform the operation. The platform
+  has a compatibility mode that allows users to revoke a legacy app's access to
+  permission-protected methods. If the user revokes access in compatibility
+  mode the app's permissions are not actually revoked; instead, access to the
+  APIs is restricted. The <code>PermissionChecker</code> methods verify app
+  permissions in both normal and legacy modes.
+</p>
+
+<p>
+  The v13 support library provides the following permissions methods:
+</p>
+
+<dl>
+  <dt>
+    <code>FragmentCompat.requestPermissions()</code>
+  </dt>
+
+  <dd>
+    If the device is not running the M Preview, invokes the callback
+    method in <code>FragmentCompat.OnRequestPermissionsResultCallback</code>.
+    Passes {@link android.content.pm.PackageManager#PERMISSION_GRANTED
+    PERMISSION_GRANTED} if the app already has the specified permission, or
+    {@link android.content.pm.PackageManager#PERMISSION_DENIED
+    PERMISSION_DENIED} if it does not.
+  </dd>
+
+  <dt>
+    <code>FragmentCompat.shouldShowRequestPermissionRationale()</code>
+  </dt>
+
+  <dd>
+    If the device is not running the M Preview, always returns
+    <code>false</code>.
+  </dd>
