RawInputCallback

com.onyx.android.sdk.pen.RawInputCallback

Abstract base class for receiving pen events from TouchHelper. All eight abstract methods must be implemented — the SDK uses an abstract class, not an interface.

Signature	Description
`void onBeginRawDrawing(boolean, TouchPoint)`	[AI Generated] Pen tip touches the surface. The `boolean` indicates whether raw drawing is currently enabled. `TouchPoint` is the initial contact point.
`void onRawDrawingTouchPointMoveReceived(TouchPoint)`	[AI Generated] Called for each sampled point during a stroke at digitizer rate (often 100–200 Hz). The SDK’s A2 renderer fires simultaneously — no `postInvalidate()` needed here unless running with `setRawDrawingRenderEnabled(false)`.
`void onEndRawDrawing(boolean, TouchPoint)`	[AI Generated] Pen tip lifts. Fired before `onRawDrawingTouchPointListReceived`.
`void onRawDrawingTouchPointListReceived(TouchPointList)`	[AI Generated] Complete stroke delivered on pen-up. Primary callback for persisting stroke data. Call `postInvalidate()` here after committing to your canvas model.
`void onBeginRawErasing(boolean, TouchPoint)`	[AI Generated] Eraser end touches the surface.
`void onRawErasingTouchPointMoveReceived(TouchPoint)`	[AI Generated] Per-point callback during an erasing gesture.
`void onEndRawErasing(boolean, TouchPoint)`	[AI Generated] Eraser end lifts.
`void onRawErasingTouchPointListReceived(TouchPointList)`	[AI Generated] Complete erasing stroke on eraser-up.
`void onPenActive(TouchPoint)`	[AI Generated] Non-abstract (no-op default). Fired when the pen hovers above the surface without touching. Useful for showing a cursor.
`void onPenUpRefresh(RectF)`	[AI Generated] Non-abstract (no-op default). Fired after the SDK’s pen-up screen refresh with the bounding rect of the refreshed area. Only fires when `setPenUpRefreshEnabled(true)`.
