where to put device_admin_sample.xml?

where to put the 'device_admin_sample.xml', its giving error wherever I put it..

device_admin_sample.xml

<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
<uses-policies>
<limit-password />
<watch-login />
<reset-password />
<force-lock开发者_开发知识库 />
<wipe-data />
</uses-policies>
</device-admin>

This should be in your /res/xml folder.

Here is a sample from ApiDemos: http://developer.android.com/resources/samples/ApiDemos/res/xml/device_admin_sample.html
