Summary

Public constructors
`FrameDataApi24( long frameStartNanos, long frameDurationUiNanos, long frameDurationCpuNanos, boolean isJank, @NonNull List<@NonNull StateInfo> states )`

Public methods
`@NonNull FrameData`	`copy()` Utility method which makes a copy of the items in this object (including copying the items in `states` into a new List).
`boolean`	`equals(Object other)`
`final long`	`getFrameDurationCpuNanos()` The time spent in the non-GPU portions of this frame (in nanoseconds).
`int`	`hashCode()`
`@NonNull String`	`toString()`

Inherited methods

From androidx.metrics.performance.FrameData

`final long`	`getFrameDurationUiNanos()` The time spent in the UI portion of this frame (in nanoseconds).
`final long`	`getFrameStartNanos()` 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.
`final @NonNull List<@NonNull StateInfo>`	`getStates()` The UI/app state during this frame.
`final boolean`	`isJank()` 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`).

Public methods

copy

public @NonNull FrameData copy()

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

public boolean equals(Object other)

getFrameDurationCpuNanos

Added in 1.0.0

public final long getFrameDurationCpuNanos()

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.

hashCode

public int hashCode()

toString

public @NonNull String toString()
