Don't convert to bytes. Store it as a string in the database- its just text. As for opening it in a webview- you would read it from the database and then call loadData() to load it into the webview.

I too think the Converting to String is the best solution. Here am pasting some codes which may help you. Get the html in the string and save it to db.. (saving to db code is omitted)
private String getDownloadButtonOnly(String url){
HttpGet pageGet = new HttpGet(url);
ResponseHandler<String> handler = new ResponseHandler<String>() {
public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException {
HttpEntity entity = response.getEntity();
String html;
if (entity != null) {
html = EntityUtils.toString(entity);
return html;
} else {
return null;
}
}
};
pageHTML = null;
try {
while (pageHTML==null){
pageHTML = client.execute(pageGet, handler);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Pattern pattern = Pattern.compile("<h2>Direct Down.+?</h2>(</div>)*(.+?)<.+?>", Pattern.DOTALL);
Matcher matcher = pattern.matcher(pageHTML);
String displayHTML = null;
while(matcher.find()){
displayHTML = matcher.group();
}
return displayHTML;
}
// after retreiving string from db,
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
//load the data
webview.loadData(summary, "text/html", null);
