class
RestrictionsManager
extends Object
java.lang.Object | |
↳ | android.content.RestrictionsManager |
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(java.lang.String, android.os.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:
<?xml version="1.0" encoding="utf-8"?> <restrictions xmlns:android="http://schemas.android.com/apk/res/android" > <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" > <restriction ... /> ... </restriction> <restriction ... /> ... </restrictions>
The attributes for each restriction depend on the restriction type.

type must have adefaultValue
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.description
is meant to describe the restriction in more detail to the administrator controlling the values, if the title is not sufficient.
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:
<application ... > <meta-data android:name="android.content.APP_RESTRICTIONS" android:resource="@xml/app_restrictions" /> ... </application>

Constants
ACTION_PERMISSION_RESPONSE_RECEIVED
public static final String ACTION_PERMISSION_RESPONSE_RECEIVED
Broadcast intent delivered when a response is received for a permission request. The application should not interrupt the user by coming to the foreground if it isn't currently in the foreground.

EXTRA_RESPONSE_BUNDLE
