## 3.9\. Device Administration Android includes features that allow security-aware applications to perform device administration functions at the system level, such as enforcing password policies or performing remote wipe, through the [Android Device Administration API](http://developer.android.com/guide/topics/admin/device-admin.html)]. If device implementations implement the full range of [device administration]( http://developer.android.com/guide/topics/admin/device-admin.html) policies defined in the Android SDK documentation, they: * [C-1-1] MUST declare `android.software.device_admin`. * [C-1-2] MUST support device owner provisioning as described in [section 3.9.1](#3_9_1_device_provisioning) and [section 3.9.1.1](#3_9_1_1_device_owner_provisioning). * [C-1-3] MUST declare the support of manged profiles via the `android.software.managed_users` feature flag, except for when the device is configured so that it would [report]( http://developer.android.com/reference/android/app/ActivityManager.html#isLowRamDevice%28%29) itself as a low RAM device or so that it allocate internal (non-removable) storage as shared storage. ### 3.9.1 Device Provisioning #### 3.9.1.1 Device owner provisioning If device implementations declare `android.software.device_admin`, they: * [C-1-1] MUST support enrolling a Device Policy Client (DPC) as a [Device Owner app]( http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#isDeviceOwnerApp%28java.lang.String%29) as described below: * When the device implementation has no user data is configured yet, it: * [C-1-3] MUST report `true` for [`DevicePolicyManager.isProvisioningAllowed(ACTION_PROVISION_MANAGED_DEVICE)`](https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html\#isProvisioningAllowed\(java.lang.String\)). * [C-1-4] MUST enroll the DPC application as the Device Owner app in response to the intent action [`android.app.action.PROVISION_MANAGED_DEVICE`](http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#ACTION_PROVISION_MANAGED_DEVICE). * [C-1-5] MUST enroll the DPC application as the Device Owner app if the device declares Near-Field Communications (NFC) support via the feature flag `android.hardware.nfc` and receives an NFC message containing a record with MIME type [`MIME_TYPE_PROVISIONING_NFC`](https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#MIME_TYPE_PROVISIONING_NFC). * When the device implementation has user data, it: * [C-1-6] MUST report `false` for the [`DevicePolicyManager.isProvisioningAllowed(ACTION_PROVISION_MANAGED_DEVICE)`](https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html\#isProvisioningAllowed\(java.lang.String\)). * [C-1-7] MUST not enroll any DPC application as the Device Owner App any more. * [C-1-2] MUST NOT set an application (including pre-installed app) as the Device Owner app without explicit consent or action from the user or the administrator of the device. If device implementations declare `android.software.device_admin`, but also include a proprietary Device Owner management solution and provide a mechanism to promote an application configured in their solution as a "Device Owner equivalent" to the standard "Device Owner" as recognized by the standard Android [DevicePolicyManager]( http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html) APIs, they: * [C-2-1] MUST have a process in place to verify that the specific app being promoted belongs to a legitimate enterprise device management solution and it has been already configured in the proprietary solution to have the rights equivalent as a "Device Owner". * [C-2-2] MUST show the same AOSP Device Owner consent disclosure as the flow initiated by [`android.app.action.PROVISION_MANAGED_DEVICE`](http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#ACTION_PROVISION_MANAGED_DEVICE) prior to enrolling the DPC application as "Device Owner". * MAY have user data on the device prior to enrolling the DPC application as "Device Owner". #### 3.9.1.2 Managed profile provisioning If device implementations declare `android.software.managed_users`, they: * [C-1-1] MUST implement the [APIs](http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#ACTION_PROVISION_MANAGED_PROFILE) allowing a Device Policy Controller (DPC) application to become the [owner of a new Managed Profile](http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#isProfileOwnerApp%28java.lang.String%29). * [C-1-2] The managed profile provisioning process (the flow initiated by [android.app.action.PROVISION_MANAGED_PROFILE]( http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#ACTION_PROVISION_MANAGED_PROFILE)) users experience MUST align with the AOSP implementation. * [C-1-3] MUST provide the following user affordances within the Settings to indicate to the user when a particular system function has been disabled by the Device Policy Controller (DPC): * A consistent icon or other user affordance (for example the upstream AOSP info icon) to represent when a particular setting is restricted by a Device Admin. * A short explanation message, as provided by the Device Admin via the [`setShortSupportMessage`]( https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#setShortSupportMessage%28android.content.ComponentName, java.lang.CharSequence%29). * The DPC application’s icon. ## 3.9.2 Managed Profile Support If device implementations declare `android.software.managed_users`, they: * [C-1-1] MUST support managed profiles via the `android.app.admin.DevicePolicyManager` APIs. * [C-1-2] MUST allow one and only [one managed profile to be created](http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#ACTION_PROVISION_MANAGED_PROFILE). * [C-1-3] MUST use an icon badge (similar to the AOSP upstream work badge) to represent the managed applications and widgets and other badged UI elements like Recents & Notifications. * [C-1-4] MUST display a notification icon (similar to the AOSP upstream work badge) to indicate when user is within a managed profile application. * [C-1-5] MUST display a toast indicating that the user is in the managed profile if and when the device wakes up (ACTION_USER_PRESENT) and the foreground application is within the managed profile. * [C-1-6] Where a managed profile exists, MUST show a visual affordance in the Intent 'Chooser' to allow the user to forward the intent from the managed profile to the primary user or vice versa, if enabled by the Device Policy Controller. * [C-1-7] Where a managed profile exists, MUST expose the following user affordances for both the primary user and the managed profile: * Separate accounting for battery, location, mobile data and storage usage for the primary user and managed profile. * Independent management of VPN Applications installed within the primary user or managed profile. * Independent management of applications installed within the primary user or managed profile. * Independent management of accounts within the primary user or managed profile. * [C-1-8] MUST ensure the preinstalled dialer, contacts and messaging applications can search for and look up caller information from the managed profile (if one exists) alongside those from the primary profile, if the Device Policy Controller permits it. * [C-1-9] MUST ensure that it satisfies all the security requirements applicable for a device with multiple users enabled (see[section 9.5](#9_5_multi-user_support)), even though the managed profile is not counted as another user in addition to the primary user. * [C-1-10] MUST support the ability to specify a separate lock screen meeting the following requirements to grant access to apps running in a managed profile. * Device implementations MUST honor the [`DevicePolicyManager.ACTION_SET_NEW_PASSWORD`](https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#ACTION_SET_NEW_PASSWORD) intent and show an interface to configure a separate lock screen credential for the managed profile. * The lock screen credentials of the managed profile MUST use the same credential storage and management mechanisms as the parent profile, as documented on the [Android Open Source Project Site](http://source.android.com/security/authentication/index.html) * The DPC [password policies](https://developer.android.com/guide/topics/admin/device-admin.html#pwd) MUST apply to only the managed profile's lock screen credentials unless called upon the `DevicePolicyManager` instance returned by getParentProfileInstance. * When contacts from the managed profile are displayed in the preinstalled call log, in-call UI, in-progress and missed-call notifications, contacts and messaging apps they SHOULD be badged with the same badge used to indicate managed profile applications.
