E library App with pdf books in free of cost

Hello Guys,
I am Rachit and I have created a app “E library” which provides you the paid books in free of cost (pdf) . Like Wimpy Kid and all. For test purposes I have only added Wimpy Kid books. After clearing most bugs I’ll ad more books like GooseBumps , Percy Jackson , Gerinomo Stilton and etc. The bug hunters are welcomed to my app. I’ll request if anybody tries my app and founds any bug please tell me. I have attached apk file below. Please do check it. I have put my lot’s of effort in it. But I think my UI is very bad. I will definately improve my UI.

Please do check it and report me if you found any bug.
Thanks for your precious time that you read my post.
