How to read an EPUB book using EPUBLIB?

Question

I found a solution for reading epub books in android using epublib. I can read subtitles of a book. But I did not find a way to read line by line of content. How can I understand that?

Sample code for getting book titles

private void logTableOfContents(List<TOCReference> tocReferences, int depth) { if (tocReferences == null) { return; } for (TOCReference tocReference : tocReferences) { StringBuilder tocString = new StringBuilder(); StringBuilder tocHref=new StringBuilder(); for (int i = 0; i < depth; i++) { tocString.append("\t"); tocHref.append("\t"); } tocString.append(tocReference.getTitle()); tocHref.append(tocReference.getCompleteHref()); Log.e("Sub Titles", tocString.toString()); Log.e("Complete href",tocHref.toString()); //logTableOfContents(tocReference.getChildren(), depth + 1); } } 

Got this code from http://www.siegmann.nl/epublib/android

How can I get a story about a book ...

Answer 1

I'm not sure if this is the way to navigate in an epub file. As far as I know (so far - I was still studying), the best way to get the whole book is based on a section of the spine. But still - I do not know how to connect these two things (TOC and the real spine) with the epublib interface. According to the documentation: "Spine sections are sections of a book in the order the book should be read. This contrasts with the sections" Content ", which is an index in the" Books "section.

this is something - if you are alike - this is a snippet:

 Spine spine = new Spine(book.getTableOfContents()); for (SpineReference bookSection : spine.getSpineReferences()) { Resource res = bookSection.getResource(); try { InputStream is = res.getInputStream(); //do something with stream } catch (IOException e) {

Well, I'm not sure about navigation, but I'm wondering how to do it. At the moment - I have something like this (this is line by line):

 private void logTableOfContents(List<TOCReference> tocReferences, int depth) { if (tocReferences == null) { return; } for (TOCReference tocReference : tocReferences) { StringBuilder tocString = new StringBuilder(); for (int i = 0; i < depth; i++) { tocString.append("\t"); } try{ InputStream is = tocReference.getResource().getInputStream(); BufferedReader r = new BufferedReader(new InputStreamReader(is)); String line; while ((line = r.readLine()) != null) { String line = Html.fromHtml(line).toString(); } } catch(IOException e){ } //logTableOfContents(tocReference.getChildren(), depth + 1); } }

I am trying to read all the text in an epub file in line with this code, but it does not work! How can i do this?
