Public properties
Long

The time spent in the non-GPU portions of this frame (in nanoseconds).

Inherited properties
From androidx.metrics.performance.FrameData
Long

The time spent in the UI portion of this frame (in nanoseconds).
Long

These backing fields are used to enable mutation of an existing FrameData object, to avoid allocating a new object on every frame for sending out to listeners.
Boolean

Whether this frame was determined to be janky, meaning that its duration exceeds the duration determined by the system to indicate jank (@see JankStats.jankHeuristicMultiplier).
List<StateInfo>

The UI/app state during this frame.

Public functions

copy

open fun copy(): FrameData

Utility method which makes a copy of the items in this object (including copying the items in states into a new List). This is used internally to create a copy to pass along to listeners to avoid having a reference to the internally-mutable FrameData object.

equals

open operator fun equals(other: Any?): Boolean

hashCode

open fun hashCode(): Int

toString

open fun toString(): String

Public properties

frameDurationCpuNanos

Added in 1.0.0-beta01
val frameDurationCpuNanos: Long

The time spent in the non-GPU portions of this frame (in nanoseconds). This includes the time spent on the UI thread frameDurationUiNanos plus time spent on the RenderThread.
