1 Android AppRestrictionSchema Sample 2 =================================== 3 4 A basic app showing how to allow a device administrator to restrict user 5 activities using the Android Device Administration API. The app exports 6 a custom policy that enables or disables a UI control. Device Administration 7 applications are able to enforce a specific value for this policy, as 8 directed by enterprise administrators. 9 10 Introduction 11 ------------ 12 13 The [Android Device Administration API][1] allows enterprise administrators to 14 enforce specific policies on a managed device. The system provides policies 15 that control settings such as password complexity, screen lock, or camera 16 availability. Developers can also augment this list with custom policies 17 that control specific features within their applications. For example, 18 a web browser could provide access to a whitelist of allowed domains. 19 20 The list of policies exposed by an app must be specified using a file 21 inside of the `res/xml` directory, using the `<restriction>` tag: 22 23 ```xml 24 <restrictions xmlns:android="http://schemas.android.com/apk/res/android"> 25 26 <restriction 27 android:defaultValue="false" 28 android:description="@string/description_can_say_hello" 29 android:key="can_say_hello" 30 android:restrictionType="bool" 31 android:title="@string/title_can_say_hello" /> 32 33 </restrictions> 34 ``` 35 36 In this sample, that file can be found at 37 `Application/src/main/res/xml/app_restrictions.xml`. This file must be 38 also be declared inside of `ApplicationManifest.xml` using a `<meta-data>` 39 element: 40 41 ```xml 42 <meta-data 43 android:name="android.content.APP_RESTRICTIONS" 44 android:resource="@xml/app_restrictions" /> 45 ``` 46 47 At runtime, the current list of restrictions enforced by policy can be 48 checked by calling [RestrictionsManager.getApplicationRestrictions()][2]. 49 50 [1]: http://developer.android.com/guide/topics/admin/device-admin.html 51 [2]: https://developer.android.com/reference/android/content/RestrictionsManager.html#getApplicationRestrictions() 52 53 Pre-requisites 54 -------------- 55 56 - Android SDK v21 57 - Android Build Tools v21.1.1 58 - Android Support Repository 59 60 Screenshots 61 ------------- 62 63 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 64 65 Getting Started 66 --------------- 67 68 This sample uses the Gradle build system.
