如果你的epub文件在assets文件夹中，那么试试这个

...
nl.siegmann.epublib.domain.Book book=null;
    try {
        AssetManager assetManager = getAssets();
        AssetFileDescriptor assetFileDescriptor = assetManager.openFd("book/test.epub");  
        FileDescriptor fileDescriptor = assetFileDescriptor.getFileDescriptor();  
        FileInputStream stream = new FileInputStream(fileDescriptor);
        EpubReader epubReader = new EpubReader();
        book = epubReader.readEpub(stream);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
