PowerMonitor

Kotlin |Java

public final class PowerMonitor
extends Object implements Parcelable

java.lang.Object
↳	android.os.PowerMonitor

A PowerMonitor represents either an ODPM rail (on-device power rail monitor) or a modeled energy consumer.

ODPM rail names are device-specific. No assumptions should be made about the names and exact purpose of ODPM rails across different device models. A rail name may be something like "S2S_VDD_G3D"; specific knowledge of the device hardware is required to interpret the corresponding power monitor data.

Energy consumer have more human-readable names, e.g. "GPU", "MODEM" etc. However, developers must be extra cautious about using energy consumers across different device models, as their exact implementations are also hardware dependent and are customized by OEMs.

Summary

Constants
`int`	`POWER_MONITOR_TYPE_CONSUMER` Power monitor corresponding to a subsystem.
`int`	`POWER_MONITOR_TYPE_MEASUREMENT` Power monitor corresponding to a directly measured power rail.

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<PowerMonitor>`	`CREATOR`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`String`	`getName()` Returns the name of the power monitor, either a power rail or an energy consumer.
`int`	`getType()` Returns the type of the power monitor.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

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

POWER_MONITOR_TYPE_CONSUMER

Added in API level 35

public static final int POWER_MONITOR_TYPE_CONSUMER

Power monitor corresponding to a subsystem. The energy value may be a direct pass-through power rail measurement, or modeled in some fashion. For example, an energy consumer may represent a combination of multiple rails or a portion of a rail shared between subsystems, e.g. WiFi and Bluetooth are often handled by the same chip, powered by a shared rail. Some consumer names are standardized, others are not.

Constant Value: 0 (0x00000000)

POWER_MONITOR_TYPE_MEASUREMENT

Added in API level 35

public static final int POWER_MONITOR_TYPE_MEASUREMENT

Power monitor corresponding to a directly measured power rail. Rails are device-specific: no assumptions can be made about the source of those measurements across different devices, even if they have the same name.

Constant Value: 1 (0x00000001)

Fields

CREATOR

Added in API level 35

public static final Creator<PowerMonitor> CREATOR

Public methods

describeContents

Added in API level 35

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getName

Added in API level 35

public String getName ()

Returns the name of the power monitor, either a power rail or an energy consumer.

Returns
`String`	This value cannot be `null`.

getType

Added in API level 35

public int getType ()

Returns the type of the power monitor.

Returns
`int`	Value is either `0` or a combination of `POWER_MONITOR_TYPE_CONSUMER`, and `POWER_MONITOR_TYPE_MEASUREMENT`

writeToParcel

Added in API level 35

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
