RestrictionsManager


public class RestrictionsManager
extends Object

java.lang.Object
   ↳ android.content.RestrictionsManager


Provides a mechanism for apps to query restrictions imposed by an entity that manages the user. Apps can also send permission requests to a local or remote device administrator to override default app-specific restrictions or any other operation that needs explicit authorization from the administrator.

Apps can expose a set of restrictions via an XML file specified in the manifest.

If the user has an active Restrictions Provider, dynamic requests can be made in addition to the statically imposed restrictions. Dynamic requests are app-specific and can be expressed via a predefined set of request types.

The RestrictionsManager forwards the dynamic requests to the active Restrictions Provider. The Restrictions Provider can respond back to requests by calling notifyPermissionResponse(java.lang.String, android.os.PersistableBundle), when a response is received from the administrator of the device or user. The response is relayed back to the application via a protected broadcast, ACTION_PERMISSION_RESPONSE_RECEIVED.

Static restrictions are specified by an XML file referenced by a meta-data attribute in the manifest. This enables applications as well as any web administration consoles to be able to read the list of available restrictions from the apk.

The syntax of the XML format is as follows:

 <?xml version="1.0" encoding="utf-8"?>
 <restrictions xmlns:android="http://schemas.android.com/apk/res/android" >
     <restriction
         android:key="string"
         android:title="string resource"
         android:restrictionType=["bool" | "string" | "integer"
                                         | "choice" | "multi-select" | "hidden"
                                         | "bundle" | "bundle_array"]
         android:description="string resource"
         android:entries="string-array resource"
         android:entryValues="string-array resource"
         android:defaultValue="reference" >
             <restriction ... />
             ...
     </restriction>
     <restriction ... />
     ...
 </restrictions>
 

The attributes for each restriction depend on the restriction type.

  • key, title and restrictionType are mandatory.
  • entries and entryValues are required if restrictionType is choice or multi-select.
  • defaultValue is optional and its type depends on the restrictionType
  • hidden type must have a defaultValue and will not be shown to the administrator. It can be used to pass along data that cannot be modified, such as a version code.
  • description is meant to describe the restriction in more detail to the administrator controlling the values, if the title is not sufficient.

Only restrictions of type bundle and bundle_array can have one or multiple nested restriction elements.

In your manifest's application section, add the meta-data tag to point to the restrictions XML file as shown below:

 <application ... >
     <meta-data android:name="android.content.APP_RESTRICTIONS"
                   android:resource="@xml/app_restrictions" />
     ...
 </application>

Converts a list of restrictions to the corresponding bundle, using the following mapping:

RestrictionEntryBundle
RestrictionEntry#TYPE_BOOLEANBundle#putBoolean
RestrictionEntry#TYPE_CHOICE, RestrictionEntry#TYPE_MULTI_SELECT Bundle#putStringArray
RestrictionEntry#TYPE_INTEGERBundle#putInt
RestrictionEntry#TYPE_STRINGBundle#putString

public Intent createLocalApprovalIntent ()

Returns
Intent

getApplicationRestrictions

Added in API level 21
public Bundle getApplicationRestrictions ()

Returns any available set of application-specific restrictions applicable to this application.

Returns
Bundle the application restrictions as a Bundle. Returns null if there are no restrictions.

Starting from Android version Build.VERSION_CODES.UPSIDE_DOWN_CAKE, it is possible for there to be multiple managing apps on the device with the ability to set restrictions, e.g. a Device Policy Controller (DPC) and a Supervision admin. This API will only return the restrictions set by the DPCs. To retrieve restrictions set by all managing apps, use getApplicationRestrictionsPerAdmin() instead.

getApplicationRestrictionsPerAdmin

Added in API level 34
public List<Bundle> getApplicationRestrictionsPerAdmin ()

Returns a List containing a Bundle for each managing agent that has set restrictions for the current application, the bundle contains any application restrictions set for the current package. The order of the items in the list is not guaranteed to remain stable between multiple calls.

Starting from Android version Build.VERSION_CODES.UPSIDE_DOWN_CAKE, it is possible for there to be multiple managing apps on the device with the ability to set restrictions, e.g. an Enterprise Device Policy Controller (DPC) and a Supervision admin.

Each Bundle consists of key-value pairs, as defined by the application, where the types of values may be:

NOTE: The method performs disk I/O and shouldn't be called on the main thread
This method may take several seconds to complete, so it should only be called from a worker thread.

Returns
List<Bundle> a List of Bundle containing the restrictions set by admins for that package. Returns an empty List if there are no saved restrictions. This value cannot be null.

hasRestrictionsProvider

Added in API level 21
public boolean hasRestrictionsProvider ()

Called by an application to check if there is an active Restrictions Provider. If there isn't, requestPermission(java.lang.String, java.lang.String, android.os.PersistableBundle) is not available.

                String requestId, 
                PersistableBundle request)

Called by an application to request permission for an operation. The contents of the request are passed in a Bundle that contains several pieces of data depending on the chosen request type.

Parameters

For custom types, the type name should be namespaced to avoid collisions with predefined types and types specified by other Restrictions Providers.

requestId String: A unique id generated by the app that contains sufficient information to identify the parameters of the request when it receives the id in the response.

request PersistableBundle: A PersistableBundle containing the data corresponding to the specified request type. The keys for the data in the bundle depend on the request type.

Throws
IllegalArgumentException if any of the required parameters are missing.
