Java Spen SDK的基本示例程序引发运行时异常

我正在编写一个基本的android应用程序，涉及Spen SDK。我的XML文件是：-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

  <FrameLayout
        android:id="@+id/canvas_container"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <com.samsung.sdraw.CanvasView
            android:id="@+id/canvas_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/ic_launcher"
            />
        <com.samsung.sdraw.SettingView
            android:id="@+id/setting_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </FrameLayout>
</RelativeLayout> 

我一编写这个XML，预览面板中就会出现一些错误。屏幕截图附在下面：

错误是：-

Rendering Problems:  
The following classes could not be instantiated:  
- com.samsung.sdraw.CanvasView (Open Class, Show Exception)  
- com.samsung.sdraw.SettingView (Open Class, Show Exception)  
 Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in   the IDE

渲染问题：
无法实例化以下类：
-com.samsung.sdraw.CanvasView（开放类，显示异常）
-com.samsung.sdraw.SettingView（开放类，显示异常）
提示：在自定义视图中使用View.isInEditMode（）可以在IDE中显示时跳过代码或显示示例数据
例外情况详细信息（应用程序是否在您的设备上运行？它显示第一个屏幕，然后立即崩溃……错误不是编译时，它的运行时您是否正确添加了三星移动SDK？LogCat的堆栈跟踪是什么？要添加SDK，我将libspen23.jar、libspen23_multiwindow.jar和armeabi目录复制到我的项目的lib目录中t、 然后我右键单击jar并添加libspen23.jar和libspen23_multiwindow.jar作为库…我还更新了问题中的logcat
