Please share your code. Not some gist. You have to use some javascript interface to call the epub reader library in your book-data object.

This is my code i have written android for reading epub book and loading its html contents into webview using monocle.

        wv = (WebView)findViewById(R.id.bookView);
        try
        {
               InputStream epubInputStream = new   FileInputStream(DEFAULT_INITIAL_DIRECTORY);
           book = (new EpubReader()).readEpub(epubInputStream);
           DownloadResource(DEFAULT_INITIAL_DIRECTORY);
               contents = getEntireBook();
         }
        catch(Exception e){
            Log.e("epublib", e.getMessage());
        }
        wv.getSettings().setJavaScriptEnabled(true);
        JSInterface = new JavaScriptInterface(this);
        wv.addJavascriptInterface(JSInterface, "JSInterface"); 

        File file = null;
        try 
        {
            file = new File(Environment.getExternalStorageDirectory() + File.separator + "contents.html");
            if(!file.exists())
                file.createNewFile();
            if(file.exists())
            {
                 OutputStream fo = new FileOutputStream(file);              
                 fo.write(contents.getBytes());
                 fo.close();
            }     
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

Can you show your updated book-data-object where you are calling the interface?

First i read my epub book the code is given below i convert my book to html

       InputStream epubInputStream = new   FileInputStream(DEFAULT_INITIAL_DIRECTORY);
       book = (new EpubReader()).readEpub(epubInputStream);
       DownloadResource(DEFAULT_INITIAL_DIRECTORY);
       contents = getEntireBook();

Then i load these html contents in a file named contents.html code given below

File file = null; try { file = new File(Environment.getExternalStorageDirectory() + File.separator + "contents.html"); if(!file.exists()) file.createNewFile(); if(file.exists()) { OutputStream fo = new FileOutputStream(file);
fo.write(contents.getBytes()); fo.close(); }
} catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } Then i have written an index.html file in which i have created book data object and passing contents.html file in this book data code given below

window.reader

"

Then i load this file in my webview code given below wv.loadUrl("file:///android_asset/index.html"); When this file is loaded window.reader in the div tag is displayed instead of original book contents i do not understand what is actually happening. please solve my problem
