Restrictions Manager

Browse Source 
Mechanism to register a provider for requesting an
administrator to respond to permission requests.

Request format and response format constants.

Description of manifest template for static restrictions.
Int type introduced in RestrictionEntry.

Needs more javadoc and better description of manifest templates,
including specifying the XML attributes.

* Provides a mechanism for apps to query restrictions imposed by an entity that
* manages the user. Apps can also send permission requests to a local or remote
* device administrator to override default app-specific restrictions or any other
* operation that needs explicit authorization from the administrator.
* <p>
* Apps can expose a set of restrictions via a runtime receiver mechanism or via
* static meta data in the manifest.
* <p>
* If the user has an active restrictions provider, dynamic requests can be made in
* addition to the statically imposed restrictions. Dynamic requests are app-specific
* and can be expressed via a predefined set of templates.
* <p>
* The RestrictionsManager forwards the dynamic requests to the active
* restrictions provider. The restrictions provider can respond back to requests by calling
* {@link #notifyPermissionResponse(String, Bundle)}, when
* a response is received from the administrator of the device or user
* The response is relayed back to the application via a protected broadcast,
* {@link #ACTION_PERMISSION_RESPONSE_RECEIVED}.
* <p>
* Static restrictions are specified by an XML file referenced by a meta-data attribute
* in the manifest. This enables applications as well as any web administration consoles
* to be able to read the template from the apk.
* <p>
* The syntax of the XML format is as follows:
* <pre>
* &lt;restrictions&gt;
* &lt;restriction
* android:key="&lt;key&gt;"
* android:restrictionType="boolean|string|integer|multi-select|null"
* ... /&gt;
