Are you using the demo project, or your modified version?
Can you replicate this with the demo project?

I works fine when i used in my project.Then i add a Horizontal List View to the my app.Then it gives me this problem.I don't know why?I think it gives me this problem when we add another view to the mail view.Also i have already overrides the onIntercepTouchEvent method.
If i tried several times i am getting below exception and app crashes.

So when the thumbnails are visible it automatically calls the onSizeChanged method and re-sized the pdf.
In first case after i double clicked the pdf size is comes to maximum and it doesn't change.But in second case it comes to maximum size and then automatically called the onSizeChanged and resized it.Could you please help me to handle this issue?

If i comment the onSizeChanged methos body does it effect to the pdf reader class?
Note: Colored methods are in Viewpager and my activity methods.
