CompanionDeviceManager

public final class CompanionDeviceManager
extends Object

java.lang.Object
   ↳ android.companion.CompanionDeviceManager


System level service for managing companion devices

To obtain an instance call getSystemService(Class)(COMPANION_DEVICE_SERVICE) Then, call associate(AssociationRequest, Callback, Handler) to initiate the flow of associating current package with a device selected by user.

Summary

Nested classes

class CompanionDeviceManager.Callback

A callback to receive once at least one suitable device is found, or the search failed (e.g. 

Constants

String EXTRA_DEVICE

A device, returned in the activity result of the IntentSender received in onDeviceFound(IntentSender)

Public methods

void associate(AssociationRequest request, CompanionDeviceManager.Callback callback, Handler handler)

Associate this app with a companion device, selected by user

Once at least one appropriate device is found, callback will be called with a PendingIntent that can be used to show the list of available devices for the user to select.

void disassociate(String deviceMacAddress)

Remove the association between this app and the device with the given mac address.

List<String> getAssociations()
boolean hasNotificationAccess(ComponentName component)

Check whether the given component can access the notifications via a NotificationListenerService Your app must have an association with a device before calling this API

void requestNotificationAccess(ComponentName component)

Request notification access for the given component.

Inherited methods

From class java.lang.Object

Constants

EXTRA_DEVICE

String EXTRA_DEVICE

A device, returned in the activity result of the IntentSender received in onDeviceFound(IntentSender)

Constant Value: "android.companion.extra.DEVICE"

Public methods

associate

void associate (AssociationRequest request, 
                CompanionDeviceManager.Callback callback, 
                Handler handler)

Associate this app with a companion device, selected by user

Once at least one appropriate device is found, callback will be called with a PendingIntent that can be used to show the list of available devices for the user to select. It should be started for result (i.e. using startIntentSenderForResult(IntentSender, int, Intent, int, int, int)), as the resulting Intent will contain extra EXTRA_DEVICE, with the selected device. (e.g. BluetoothDevice)

If your app needs to be excluded from battery optimizations (run in the background) or to have unrestricted data access (use data in the background) you can declare that you use the RUN_IN_BACKGROUND and USE_DATA_IN_BACKGROUND respectively. Note that these special capabilities have a negative effect on the device's battery and user's data usage, therefore you should requested them when absolutely necessary.

You can call getAssociations() to get the list of currently associated devices, and disassociate(String) to remove an association. Consider doing so when the association is no longer relevant to avoid unnecessary battery and/or data drain resulting from special privileges that the association provides

Parameters
request AssociationRequest: specific details about this request
callback CompanionDeviceManager.Callback: will be called once there's at least one device found for user to choose from
handler Handler: A handler to control which thread the callback will be delivered on, or null, to deliver it on main thread

disassociate

void disassociate (String deviceMacAddress)

Remove the association between this app and the device with the given mac address.

Any privileges provided via being associated with a given device will be revoked

Consider doing so when the association is no longer relevant to avoid unnecessary battery and/or data drain resulting from special privileges that the association provides

Parameters
deviceMacAddress String: the MAC address of device to disassociate from this app

getAssociations

List<String> getAssociations ()

Returns
List<String> a list of MAC addresses of devices that have been previously associated with the current app. You can use these with disassociate(String)

hasNotificationAccess

boolean hasNotificationAccess (ComponentName component)

Check whether the given component can access the notifications via a NotificationListenerService Your app must have an association with a device before calling this API

Parameters
component ComponentName: the name of the component
Returns
boolean whether the given component has the notification listener permission

requestNotificationAccess

void requestNotificationAccess (ComponentName component)

Request notification access for the given component. The given component must follow the protocol specified in NotificationListenerService Only components from the same package as the calling app are allowed. Your app must have an association with a device before calling this API

Parameters
component ComponentName
