+Steps to implement FragmentView template:
+-in template-params.xml.ftl:
+    -add the following line to common imports
+        <common src="activities"/>
+
+-Add a Fragment to show behavior.  In your MainActivity.java class, it will reference a Fragment
+ called (yourProjectName)Fragment.java.  Create that file in your project, using the "main" source
+ folder instead of "common" or "templates".
+   For instance, if your package name is com.example.foo, create the file
+   src/main/java/com/example/foo/FooFragment.java
+
+
+-Within this fragment, make sure that the onCreate method has the line
+ "setHasOptionsMenu(true);", to enable the fragment to handle menu events.
+
+-In order to override menu events, override onOptionsItemSelected.
+
+-refer to sampleSamples/fragmentViewSample for a reference implementation of a
+project built on this template.

+<![CDATA[
+This sample demonstrates how to use the PermissionRequest API to
+securely provide access to restricted system features (such as a
+camera or microphone) from within a WebView. In this example, a dialog
+is created to allow users to explicitly approve or reject each
+request.
+]]>
+        </description>
+
+        <intro>
+<![CDATA[
+PermissionRequest can be used by setting up a custom WebChromeClient.
+
+```java
+mWebView.setWebChromeClient(mWebChromeClient);
+```
+
+In you WebChromeClient implementation, you need to override
+[onPermissionRequest][1]. This method is called when the web content
+is requesting permission to access some resources, providing an
+opportunity to approve or reject the request. In this implementation,
+we display a dialog to allow the user to approve or reject any
+request. In other applications, you may want to implement a whitelist
+of allowed APIs.  Also, override [onPermissionRequestCanceled][2] for
+handling cancellation of the PermissionRequest by the web content.
+
+When the user confirms or denies the request, you can respond back to
+the web content by [grant][3] or [deny][4] respectively.
+
+```java
+mPermissionRequest.grant(mPermissionRequest.getResources());
+```
+
+This sample provides the web content from the assets folder in the
+app. Since WebView is not allowed to use getUserMedia from a "file://"
+URL, the app uses the SimpleWebServer class to provide the content via
+"http://localhost".
