Normally, finding an e-book, downloading, reading e-book are operations that we have to do separately by different tools. We also have to manage our e-book files manually. It will be more convenience if we have an all-in-one application that we can do all tasks with it. In the meantime, Android becomes popularly more and more because it is open feature and very powerful. From those motivations, we would like to design an e-book reader running on Android mobile devices. It supports two most popular e-book formats: PDF and EPUB. It is also a bookshelf that helps users to manage and organize book files and other related information logically.
For that application, Graphic User Interface (GUI) is an important part since it needs to be friendly and fancy to catch user’s attention. Small touchable screen can be the challenge so GUI has to be efficient and easy to use. In addition, because of mobile phone has constraint in memory, managing memory usage is also very important that keep system run stably and efficiently.
