BOOX GO 10.3设备Onyx SDK RawDrawing功能失效求助

我正在BOOX GO 10.3设备上尝试通过Onyx SDK启用RawDrawing功能，此前在BOOX Note 2上通过以下代码成功实现该功能：

TouchHelper touchHelper = TouchHelper.create(surfaceView, getRawInputCallback());
touchHelper.openRawDrawing();
touchHelper.setRawDrawingEnabled(true);

但在BOOX GO 10.3上，尽管TouchHelper初始化成功，getRawInputCallback()中却无法接收到手写笔输入。设备未出现报错，但尝试书写时无任何反应——而在NOTE 2上能正常生成日志。

我有以下疑问：

• BOOX GO 10.3是否更改了RawDrawing输入的工作方式？
• 手写笔输入是否需要新版本SDK或不同实现方法？
• 是否存在安全限制导致无法访问ViewUpdateHelper和EpdController？

若能提供相关指导或更新文档，我将不胜感激！

以下是用于生成日志的补充代码：

public RawInputCallback getRawInputCallback() {
    if (rawInputCallback == null) {
        rawInputCallback = new RawInputCallback() {
            @Override
            public void onBeginRawDrawing(boolean b, TouchPoint touchPoint) {
                Log.d(TAG, "onBeginRawDrawing: " + touchPoint);
            }
            @Override
            public void onRawDrawingTouchPointMoveReceived(TouchPoint touchPoint) {
                Log.d(TAG, "onRawDrawingTouchPointMoveReceived: " + touchPoint);
            }
            @Override
            public void onRawDrawingTouchPointListReceived(TouchPointList touchPointList) {
                Log.d(TAG, "onRawDrawingTouchPointListReceived: " + touchPointList.size());
            }
            @Override
            public void onEndRawDrawing(boolean b, TouchPoint touchPoint) {
                Log.d(TAG, "onEndRawDrawing: " + touchPoint);
            }
            @Override
            public void onBeginRawErasing(boolean b, TouchPoint touchPoint) {
                //touchHelper.setRawDrawingRenderEnabled(false);
            }
            @Override
            public void onEndRawErasing(boolean b, TouchPoint touchPoint) {
                //touchHelper.setRawDrawingRenderEnabled(true);
            }
            @Override
            public void onRawErasingTouchPointMoveReceived(TouchPoint touchPoint) {
                // Handle erasing move
            }
            @Override
            public void onRawErasingTouchPointListReceived(TouchPointList touchPointList) {
                // Handle erasing points received
            }
        };
    }
    return rawInputCallback;
}
