DeviceLockManager

Kotlin |Java

public final class DeviceLockManager
extends Object

java.lang.Object
↳	android.devicelock.DeviceLockManager

Manager used to interact with the system device lock service. The device lock feature is used by special applications ('kiosk apps', downloaded and installed by the device lock solution) to lock and unlock a device. A typical use case is a financed device, where the financing entity has the capability to lock the device in case of a missed payment. When a device is locked, only a limited set of interactions with the device is allowed (for example, placing emergency calls).

Use Context.getSystemService(java.lang.String) with Context.DEVICE_LOCK_SERVICE to create a DeviceLockManager.

Requires the PackageManager#FEATURE_DEVICE_LOCK feature which can be detected using PackageManager.hasSystemFeature(String).

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Constants

DEVICE_LOCK_ROLE_FINANCING

Added in API level 34

public static final int DEVICE_LOCK_ROLE_FINANCING

Constant representing a financed device role, returned by getKioskApps(Executor, OutcomeReceiver).

Constant Value: 0 (0x00000000)

Public methods

getDeviceId

Added in API level 34

public void getDeviceId (Executor executor, 
                OutcomeReceiver<DeviceId, Exception> callback)

Get the device id.
Requires Manifest.permission.MANAGE_DEVICE_LOCK_STATE

Parameters
`executor`	`Executor`: the `Executor` on which to invoke the callback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`callback`	`OutcomeReceiver`: this returns either the `DeviceId` or an exception. This value cannot be `null`.

getKioskApps

Added in API level 34

public void getKioskApps (Executor executor, 
                OutcomeReceiver<Map<Integer, String>, Exception> callback)

Get the kiosk app roles and packages.

Parameters
`executor`	`Executor`: the `Executor` on which to invoke the callback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`callback`	`OutcomeReceiver`: this returns either a `Map` of device roles/package names, or an exception. The Integer in the map represent the device lock role (at this moment, the only supported role is `.DEVICE_LOCK_ROLE_FINANCING`. The String represents tha package name of the kiosk app for that role. This value cannot be `null`.

isDeviceLocked

Added in API level 34

public void isDeviceLocked (Executor executor, 
                OutcomeReceiver<Boolean, Exception> callback)

Check if the device is locked or not.
Requires Manifest.permission.MANAGE_DEVICE_LOCK_STATE

Parameters
`executor`	`Executor`: the `Executor` on which to invoke the callback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`callback`	`OutcomeReceiver`: this returns either the lock status or an exception. This value cannot be `null`.

lockDevice

Added in API level 34

public void lockDevice (Executor executor, 
                OutcomeReceiver<Void, Exception> callback)

Lock the device.
Requires Manifest.permission.MANAGE_DEVICE_LOCK_STATE

Parameters
`executor`	`Executor`: the `Executor` on which to invoke the callback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`callback`	`OutcomeReceiver`: this returns either success or an exception. This value cannot be `null`.

unlockDevice

Added in API level 34

public void unlockDevice (Executor executor, 
                OutcomeReceiver<Void, Exception> callback)

Unlock the device.
Requires Manifest.permission.MANAGE_DEVICE_LOCK_STATE

Parameters
`executor`	`Executor`: the `Executor` on which to invoke the callback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`callback`	`OutcomeReceiver`: this returns either success or an exception. This value cannot be `null`.
