Posibility 1: version problem. Make your minimum and target sdk version higher and try again. Posibility 2: package mistmatching. Package name in AndroidManifest.xml does not match with the actual package that your activity is associated with. Three steps to solve this problem: Step 1. Check your header file from your AndroidManifest.xml. <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.yourdomain.yourapp" android:versionCode="1" android:versionName="1.0" >

내 경우는 둘다 아니였고, 

.xml 파일에서

        <com.samsung.sdraw.CanvasView

            android:id="@+id/canvas"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content" />

        <com.samsung.sdraw.SettingView

            android:id="@+id/setting"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content" />

등의 외부 view를 가져올때의 뷰 이름을 잘못쓰면 나타나더라.

혹은 project-clean을 하거나

refresh 하거나

eclipse를 재부팅하면 해결된다.
