This sample shows how to use app restrictions. This application has one boolean
|
|
restriction with a key \"can_say_hello\" that defines whether the only feature of this
|
|
app (press the button to show \"Hello\" message) is enabled or disabled. Use
|
|
AppRestrictionEnforcer sample to toggle the restriction.

|
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][1] 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:
|
|
|
|
```xml
|
|
<restrictions xmlns:android="http://schemas.android.com/apk/res/android">
|
|
|
|
<restriction
|
|
android:defaultValue="false"
|
|
android:description="@string/description_can_say_hello"
|
|
android:key="can_say_hello"
|
|
android:restrictionType="bool"
|
|
android:title="@string/title_can_say_hello" />
|
|
|
|
</restrictions>
|
|
```
|
|
|
|
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:
|
|
|
|
```xml
|
|
<meta-data
|
|
android:name="android.content.APP_RESTRICTIONS"
|
|
android:resource="@xml/app_restrictions" />
|
|
```
|
|
|
|
At runtime, the current list of restrictions enforced by policy can be
|
|
checked by calling [RestrictionsManager.getApplicationRestrictions()][2].
