Android AppRestrictionSchema Sample

A basic app showing how to allow a device administrator to restrict user activities using the Android Device Administration API. The app exports a custom policy that enables or disables a UI control. Device Administration applications are able to enforce a specific value for this policy, as directed by enterprise administrators.


The Android Device Administration API allows enterprise administrators to enforce specific policies on a managed device. The system provides policies that control settings such as password complexity, screen lock, or camera availability. Developers can also augment this list with custom policies that control specific features within their applications. For example, a web browser could provide access to a whitelist of allowed domains.

The list of policies exposed by an app must be specified using a file inside of the res/xml directory, using the <restriction> tag:

<restrictions xmlns:android="">

            android:title="@string/title_can_say_hello" />


In this sample, that file can be found at Application/src/main/res/xml/app_restrictions.xml. This file must be also be declared inside of ApplicationManifest.xml using a <meta-data> element:

        android:resource="@xml/app_restrictions" />

At runtime, the current list of restrictions enforced by policy can be checked by calling RestrictionsManager.getApplicationRestrictions().
