问题
I am writing a basic android app involving Spen SDK. My XML file is:-
<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>
As soon as I write this XML, some error pops up in my Preview Panel. The screen-shot is attached below:
The error is:-
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

Update: When I run the program, the logcat gives the following warnings once the debugger has settled:
