DeviceAdminReceiver


open class DeviceAdminReceiver : BroadcastReceiver
kotlin.Any
   ↳ android.content.BroadcastReceiver
   ↳ android.app.admin.DeviceAdminReceiver

Base class for implementing a device administration component. This class provides a convenience for interpreting the raw intent actions that are sent by the system.

The callback methods, like the base BroadcastReceiver.onReceive() method, happen on the main thread of the process. Thus long running operations must be done on another thread. Note that because a receiver is done once returning from its receive function, such long-running operations should probably be done in a Service.

When publishing your DeviceAdmin subclass as a receiver, it must handle ACTION_DEVICE_ADMIN_ENABLED and require the android.Manifest.permission#BIND_DEVICE_ADMIN permission. A typical manifest entry would look like:

The meta-data referenced here provides addition information specific to the device administrator, as parsed by the DeviceAdminInfo class. A typical file would be:

        intent: Intent,
        user: UserHandle
    ): Unit

    Called after the user has failed at entering their device or profile challenge password, as a result of receiving ACTION_PASSWORD_FAILED. At this point you can use DevicePolicyManager#getCurrentFailedPasswordAttempts() to retrieve the number of failed password attempts.

        intent: Intent,
        user: UserHandle
    ): Unit

    Called after the user has succeeded at entering their device or profile challenge password, as a result of receiving ACTION_PASSWORD_SUCCEEDED. This will only be received the first time they succeed after having previously failed.

    Parameters
    context Context: The running context as per onReceive. This value cannot be null.

    onProfileProvisioningComplete

    Added in API level 21
    open fun onProfileProvisioningComplete(
        context: Context,
        intent: Intent
    ): Unit

    Called when provisioning of a managed profile or managed device has completed successfully.

    As a prerequisite for the execution of this callback the DeviceAdminReceiver has to declare an intent filter for ACTION_PROFILE_PROVISIONING_COMPLETE. Its component must also be specified in the DevicePolicyManager#EXTRA_DEVICE_ADMIN of the DevicePolicyManager#ACTION_PROVISION_MANAGED_PROFILE intent that started the managed provisioning.

    When provisioning of a managed profile is complete, the managed profile is hidden until the profile owner calls DevicePolicyManager#setProfileEnabled(ComponentName admin). Typically a profile owner will enable the profile when it has finished any additional setup such as adding an account by using the AccountManager and calling APIs to bring the profile into the desired state.

    Note that provisioning completes without waiting for any server interactions, so the profile owner needs to wait for data to be available if required (e.g. Android device IDs or other data that is set as a result of server interactions).

    From version android.os.Build.VERSION_CODES#O, when managed provisioning has completed, along with this callback the activity intent DevicePolicyManager#ACTION_PROVISIONING_SUCCESSFUL will also be sent to the same application.

    The Intent may include any of the extras specified for ACTION_PROFILE_PROVISIONING_COMPLETE.

    Parameters
    context Context: The running context as per onReceive. This value cannot be null.
    intent Intent: The received intent as per onReceive. This value cannot be null.

    ): Unit

    Deprecated: Do not use

    Called during provisioning of a managed device to allow the device initializer to perform user setup steps.

    Parameters
    context Context: The running context as per onReceive. This value cannot be null.
    intent Intent: The received intent as per onReceive. This value cannot be null.

    onReceive

    Added in API level 8
    open fun onReceive(
        context: Context,
        intent: Intent
    ): Unit

    Intercept standard device administrator broadcasts. Implementations should not override this method; it is better to implement the convenience callbacks for each action.

    Parameters
    context Context: This value cannot be null.
    intent Intent: This value cannot be null.

    onSecurityLogsAvailable

    Added in API level 24
    open fun onSecurityLogsAvailable(
        context: Context,
        intent: Intent
    ): Unit

    Called when a new batch of security logs can be retrieved.

    If a secondary user or profile is created, this callback won't be received until all users become affiliated again (even if security logging is enabled). See DevicePolicyManager#setAffiliationIds

    This callback will be re-triggered if the logs are not retrieved.

    This callback is only applicable to device owners and profile owners of organization-owned managed profiles.

    This callback is triggered by a foreground broadcast and the app should ensure that any long-running work is not executed synchronously inside the callback.

    Parameters
    context Context: The running context as per onReceive. This value cannot be null.
    intent Intent: The received intent as per onReceive. This value cannot be null.

    onSystemUpdatePending

    Added in API level 23
    open fun onSystemUpdatePending(
        context: Context,
        intent: Intent,
        receivedTime: Long
    ): Unit

    Called when the information about a pending system update is available.

    Allows the receiver to be notified when information about a pending system update is available from the system update service. The same pending system update can trigger multiple calls to this method, so it is necessary to examine the incoming parameters for details about the update.

    This callback is only applicable to device owners and profile owners.

    To get further information about a pending system update (for example, whether or not the update is a security patch), the device owner or profile owner can call DevicePolicyManager#getPendingSystemUpdate.

    Parameters
    context Context: The running context as per onReceive. This value cannot be null.
    intent Intent: The received intent as per onReceive. This value cannot be null.
    receivedTime Long: The time as given by System#currentTimeMillis() indicating when the current pending update was first available. -1 if no pending update is available.

    onTransferAffiliatedProfileOwnershipComplete

        context: Context,
        user: UserHandle
    ): Unit

    Called on the device owner when the ownership of one of its affiliated profiles is transferred.

    This can be used when transferring both device and profile ownership when using work profile on a fully managed device. The process would look like this:

    1. Transfer profile ownership
    2. The device owner gets notified with this callback
    3. Transfer device ownership
    4. Both profile and device ownerships have been transferred
    Parameters
    context Context: the running context as per onReceive This value cannot be null.
    user UserHandle: the UserHandle of the affiliated user This value cannot be null.
