onFrame

[main]
open fun onFrame(frameTimeNanos: Long)

Base callback invoked when a new frame should be rendered.

In Inheritance Mode, subclasses should override this method if they do not require FrameData.

In Composition Mode, this delegates to the attached onFrame.

Parameters

main

frameTimeNanos	Monotonic timestamp of the frame in nanoseconds.

[main]
open fun onFrame(frameTimeNanos: Long, frameData: Any)

Main callback invoked when a new frame should be rendered, providing optional payload telemetry.

In Inheritance Mode, subclasses can override this method to receive Android 13+ FrameData.

In Composition Mode, this delegates to the attached onFrame.

Parameters

main

frameTimeNanos	Monotonic timestamp of the frame in nanoseconds.
frameData	Optional Choreographer.FrameData instance on Android 13+ (API 33). Passed as an Object to avoid verification failures on older API levels.
