My code is just:

WebView webview = (WebView) findViewById(R.id.webView1); try { InputStream inputFile = getAssets().open("linear_algebra.epub");

        nl.siegmann.epublib.epub.EpubReader reader = new nl.siegmann.epublib.epub.EpubReader();
        Book book = reader.readEpub(inputFile);
        Log.i("epublib", "title: " + book.getTitle());
        String data = new String(book.getContents().get(2).getData());
        webview.loadData(data," text/html", "utf8");

    } catch (IOException e1) {              
        e1.printStackTrace();
    }

Using readEpub() prompts epublib to load the entire asset into memory - I would suggest looking at readEpubLazy() mentioned [here](http://www.siegmann.nl/static/epublib/apidocs/nl/siegmann/epublib/epub/EpubReader.html#readEpubLazy%28java.lang.String, java.lang.String%29)
