PDF file or images for a book in android application -


i developing android book selling application problem don't know if should use books pdf file or images. reading of books inside application.

you should use .pdf extension ebook.
because images tend become pixelerated when zoomed level. pdf preserves vectors , not reduce quality of content (images, text, etc) when zoomed.
along that, pdf wrapped collection of pages in single file. instead of many different image files single ebook.

there many open source libraries rendering pdfs in android
have used mupdf library rendering pdf files in android app.
