Today, I create a extension successfully but when i open the app . it gives me this error.

What I am trying to do

i am trying to create this layout programatically

<LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent">
      <aryan.gupta.DesignView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@drawable/page1">
      </aryan.gupta.DesignView>
    </LinearLayout>

here is my java code

LinearLayout ll = new LinearLayout(context);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
initprocess = (View) ll;
designView = (DesignView) initprocess;
ll.addView(designView);

Question

why i am getting this error - Linear Layout cannot be cast to Class

Hope someone help me soon

Could you stop using usernames in your first post just to get attention. And you should ask questions about developing extension in the App Inventor community.
