Remarks

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.

Apps can expose a set of restrictions via an XML file specified in the manifest.

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 request types.

The RestrictionsManager forwards the dynamic requests to the active Restrictions Provider. The Restrictions Provider can respond back to requests by calling #notifyPermissionResponse(String, PersistableBundle), 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, #ACTION_PERMISSION_RESPONSE_RECEIVED.

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 list of available restrictions from the apk.

The syntax of the XML format is as follows:

&lt;?xml version="1.0" encoding="utf-8"?&gt;
            &lt;restrictions xmlns:android="http://schemas.android.com/apk/res/android" &gt;
                &lt;restriction
                    android:key="string"
                    android:title="string resource"
                    android:restrictionType=["bool" | "string" | "integer"
                                                    | "choice" | "multi-select" | "hidden"
                                                    | "bundle" | "bundle_array"]
                    android:description="string resource"
                    android:entries="string-array resource"
                    android:entryValues="string-array resource"
                    android:defaultValue="reference" &gt;
                        &lt;restriction ... /&gt;
                        ...
                &lt;/restriction&gt;
                &lt;restriction ... /&gt;
                ...
            &lt;/restrictions&gt;

The attributes for each restriction depend on the restriction type.

<ul> <li>key, title and restrictionType are mandatory.</li> <li>entries and entryValues are required if restrictionType is choice or multi-select.</li> <li>defaultValue is optional and its type depends on the restrictionType</li> <li>hidden type must have a defaultValue and will not be shown to the administrator. It can be used to pass along data that cannot be modified, such as a version code.</li> <li>description is meant to describe the restriction in more detail to the administrator controlling the values, if the title is not sufficient.</li> </ul>

Only restrictions of type bundle and bundle_array can have one or multiple nested restriction elements.

In your manifest's application section, add the meta-data tag to point to the restrictions XML file as shown below:

&lt;application ... &gt;
                &lt;meta-data android:name="android.content.APP_RESTRICTIONS"
                              android:resource="@xml/app_restrictions" /&gt;
                ...
            &lt;/application&gt;
