Classnotfoundexception For Custom Imageview In Android App

I am getting following exception... 08-12 14:19:41.564: ERROR/AndroidRuntime(797): Caused by: java.lang.ClassNotFoundException: com.widgets.utils.CustomRoundedCornerImageView in lo

Solution 1:

<com.widgets.utils.CustomRoundedCornerImageView 
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        android:focusable="false" />

in this you have to change

<ImageView class="com.widgets.utils.CustomRoundedCornerImageView" 
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        android:focusable="false" />
