  1. Hello, My name is John I`m from Brazil and I am using your library for an educational project.
    I was programming an app and it was working fine. Suddenly it stopped working and I tryied everything even deleting everything and downloading your example project again… Still doesn`t work. I was wondering if you could give me a little help.

    The error goes like this :

    java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{}: java.lang.ClassNotFoundException: in loader dalvik.system.PathClassLoader[/mnt/asec/]

    Thank you so much for making this library and for your time!

  2. Hi,

    I need to provide more functionalities like 1) adding notes in the margin of the book, 2) saving highlighted text in the book etc. so in this regard I may need to modify the code. Is there any way I can get the source code of the libs?


    • Anku,

      Thanks for writing to us.
      Unfortunately we are not a fully open source project and at the moment our police is to keep the lib code.
      The features you mentioned is in our plan for future development, to which we will only give priority at a cost that the customer is willing to afford.

      Best regards,
      AnFengDe Team

  3. Hi,
    First of all, thanks for all the open source efforts, it really helped me in so many ways.
    Now is there any way I could contribute to the library, I mean for example a bookmarking class, cloud sync or text highlighting.
    If there is an option for doing that I would really like to get involved.

  11. Hi folks,

    I’m starting on an iBooks style project and intend to parse ePub files. How much does it cost to remove the advertising? What is your policy regarding future updates – to update to the latest version of the library would another payment be required to remove ads again?

    i try example not open book
    then example Ui can open book want to use form internet?
    if have solution ,help me please

  13. Hi,

    I am interested in purchasing your library (I am assuming that purchasing a license will remove the ads at the bottom of the book pages? – is that correct)?

    My only concern that if I am basing my application on your library – of which i do not have access to the source code – what happens if you decide not to support this in the future? Will you agree to provide the library source code to those that have purchased it – IF you decide not to continue with this project in the future?
    This will help manage the risk of using your library in my app – and then 1-2 years from now you now supporting it anymore 🙂
