failed to get measurement in height in setDimension.

I am using API 21 and running on android 4.4.4 for the demo. After the debug time I have found that the height of the layout was not able to be generated started from this line. However, when I start running the demo project artbook and it works again.

@Override
    public void setDimensions(int measuredWidth, int measuredHeight) {
        if (measuredHeight == height && measuredWidth == width) {
            return;
        }
        this.width = measuredWidth;
        this.height = measuredHeight;
    }

My code is written under the ActionBarActivity. Are there any reason that will be malfunction? I would like to ask what are the things I need to know to avoid making a failure on measuredHeight?

Finally I found out that component <com.comcast.freeflow.core.FreeFlowContainer> cannot put under
RelativeLayout, ScrollView, LinearLayout but only can be run under FrameLayout. I think the system should remind the developer to put the <com.comcast.freeflow.core.FreeFlowContainer/> into the right layout.
