Control

---

Kotlin |Java

public final class Control
extends Object implements Parcelable

java.lang.Object
↳	android.service.controls.Control

---

Represents a physical object that can be represented by a ControlTemplate and whose properties may be modified through a ControlAction. The information is provided by a ControlsProviderService and represents static information (not current status) about the device.

Each control needs a unique (per provider) identifier that is persistent across reboots of the system.

Each Control will have a name, a subtitle and will optionally belong to a structure and zone. Some of these values are defined by the user and/or the ControlsProviderService and will be used to display the control as well as group them for management.

Each object will have an associated DeviceTypes. This will determine the icons and colors used to display it.

An Intent linking to the provider Activity that expands on this Control and allows for further actions should be provided.

Summary

Nested classes
class	Control.StatefulBuilder Builder class for Control that contains state information.
class	Control.StatelessBuilder Builder class for Control.

Constants
int	STATUS_DISABLED The Control is currently disabled.
int	STATUS_ERROR Used to indicate that there was a temporary error while loading the device state.
int	STATUS_NOT_FOUND The device corresponding to the Control cannot be found or was removed.
int	STATUS_OK Used to indicate that the state of the device was successfully retrieved.
int	STATUS_UNKNOWN Reserved for use with the StatelessBuilder, and while loading.

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.
From interface android.os.Parcelable abstract int describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. abstract void writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Constants

STATUS_DISABLED

Added in API level 30

public static final int STATUS_DISABLED

The Control is currently disabled. A default error message will be displayed in place of any custom text that was set through StatefulBuilder#setStatusText.

Constant Value: 4 (0x00000004)

STATUS_ERROR

Added in API level 30

public static final int STATUS_ERROR

Used to indicate that there was a temporary error while loading the device state. A default error message will be displayed in place of any custom text that was set through StatefulBuilder#setStatusText.

Constant Value: 3 (0x00000003)

STATUS_NOT_FOUND

Added in API level 30

public static final int STATUS_NOT_FOUND

The device corresponding to the Control cannot be found or was removed. The user will be alerted and directed to the application to resolve.

Constant Value: 2 (0x00000002)

STATUS_OK

Added in API level 30

public static final int STATUS_OK

Used to indicate that the state of the device was successfully retrieved. This includes all scenarios where the device may have a warning for the user, such as "Lock jammed", or "Vacuum stuck". Any information for the user should be set through StatefulBuilder#setStatusText.

Constant Value: 1 (0x00000001)

STATUS_UNKNOWN

Added in API level 30

public static final int STATUS_UNKNOWN

Reserved for use with the StatelessBuilder, and while loading. When state is requested via ControlsProviderService#createPublisherFor, use other status codes to indicate the proper device state.

Constant Value: 0 (0x00000000)
