I think the issue is the animation is started when onAttachedToWindow is called, but if you have the view set in the layout it can crash as soon as you start the Activity.

I have the same problem, and the dev did not respond since March ...

[fasteque]

@alaaghribi you can always fork it or push a fix or take this as an inspiration and do your own implementation. I think this library works pretty well, so I wouldn't drop it ;)

I had this crop up, and what fixed it for me was realizing that I'd put the view_pager_frame FrameLayout INSIDE the KenBurnsView. Once I realized it was supposed to be on top of it (so to speak), and moved it to outside the KenBurnsView, it worked.

[tomeroto]

can you give sample layout? I have same problem :(

[sashafiero]

<RelativeLayout>
    <com.goka.kenburnsview.KenBurnsView
        android:id="@+id/tablet_sidebar"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_toLeftOf="@id/tablet_content"/>

    <FrameLayout
        android:id="@+id/view_pager_frame"
        android:layout_width="300dp"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"/>
</RelativeLayout>

They are sibling elements, not parent/child, which was my first problem.
