The app exports 59 a custom policy that enables or disables a UI control. Device Administration 60 applications are able to enforce a specific value for this policy, as 61 directed by enterprise administrators. 62 </description> 63 64 <intro> 65 <![CDATA[ 66 The [Android Device Administration API][1] allows enterprise administrators to 67 enforce specific policies on a managed device. The system provides policies 68 that control settings such as password complexity, screen lock, or camera 69 availability. Developers can also augment this list with custom policies 70 that control specific features within their applications. For example, 71 a web browser could provide access to a whitelist of allowed domains. 72 73 The list of policies exposed by an app must be specified using a file 74 inside of the `res/xml` directory, using the `<restriction>` tag: 75 76 ```xml 77 <restrictions xmlns:android="http://schemas.android.com/apk/res/android"> 78 79 <restriction 80 android:defaultValue="false" 81 android:description="@string/description_can_say_hello" 82 android:key="can_say_hello" 83 android:restrictionType="bool" 84 android:title="@string/title_can_say_hello" /> 85 86 </restrictions> 87 ``` 88 89 In this sample, that file can be found at 90 `Application/src/main/res/xml/app_restrictions.xml`. This file must be 91 also be declared inside of `ApplicationManifest.xml` using a `<meta-data>` 92 element: 93 94 ```xml 95 <meta-data 96 android:name="android.content.APP_RESTRICTIONS" 97 android:resource="@xml/app_restrictions" /> 98 ``` 99 100 At runtime, the current list of restrictions enforced by policy can be 101 checked by calling [RestrictionsManager.getApplicationRestrictions()][2]. 102 103 [1]: http://developer.android.com/guide/topics/admin/device-admin.html 104 [2]: https://developer.android.com/reference/android/content/RestrictionsManager.html#getApplicationRestrictions() 105 ]]> 106 </intro> 107 </metadata> 108 109 </sample> 110
