The app exports 59a custom policy that enables or disables a UI control. Device Administration 60applications are able to enforce a specific value for this policy, as 61directed by enterprise administrators. 62 </description> 63 64 <intro> 65<![CDATA[ 66The [Android Device Administration API][1] allows enterprise administrators to 67enforce specific policies on a managed device. The system provides policies 68that control settings such as password complexity, screen lock, or camera 69availability. Developers can also augment this list with custom policies 70that control specific features within their applications. For example, 71a web browser could provide access to a whitelist of allowed domains. 72 73The list of policies exposed by an app must be specified using a file 74inside 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 89In this sample, that file can be found at 90`Application/src/main/res/xml/app_restrictions.xml`. This file must be 91also be declared inside of `ApplicationManifest.xml` using a `<meta-data>` 92element: 93 94```xml 95<meta-data 96 android:name="android.content.APP_RESTRICTIONS" 97 android:resource="@xml/app_restrictions" /> 98``` 99 100At runtime, the current list of restrictions enforced by policy can be 101checked 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
