HarmonyOS 鸿蒙Next 无法new FrameAnimationElement

基本信息

    Button wea;
    Button writeNote;

    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);

        ShapeElement buttonBackground = new ShapeElement();
        buttonBackground.setCornerRadius(30);
        buttonBackground.setShape(ShapeElement.RECTANGLE);
        buttonBackground.setGradientOrientation(ShapeElement.Orientation.LEFT_TO_RIGHT);
        buttonBackground.setRgbColors(new RgbColor[]{RgbPalette.GREEN, RgbPalette.YELLOW});
        wea = (Button) findComponentById(ResourceTable.Id_chooseWeather);
        writeNote = (Button) findComponentById(ResourceTable.Id_writeNote);
        wea.setClickedListener(this);
        writeNote.setClickedListener(this);
        wea.setBackground(buttonBackground);
        writeNote.setBackground(buttonBackground);

//        try {
//            frameAnimationElement = new FrameAnimationElement(getContext(), ResourceTable.Graphic_animation_element);
//
//        }catch (Exception e ){
//        e.printStackTrace();
//        }
    }

    @Override
    public void onActive() {
        super.onActive();
    }

    @Override
    public void onForeground(Intent intent) {
        super.onForeground(intent);
    }

    @Override
    public void onClick(Component component) {
        if (component == wea) {
            PickerChooseSlice pickerChooseSlice = new PickerChooseSlice();
            Intent intent = new Intent();
            present(pickerChooseSlice, intent);
        }
        if (component == writeNote) {
            WriteNotePageSlice writeNotePageSlice = new WriteNotePageSlice();
            Intent intent = new Intent();
            present(writeNotePageSlice, intent);
        }
    }
}

我是api 6的版本，语言是java

我想创建一个帧动画，跟着官方文档写，但是出现了错误

FrameAnimationElement frameAnimationElement = new FrameAnimationElement(getContext(), ResourceTable.Graphic_animation_element)

这一步无法new 显示bug : tag in not
