Android :: EPUB Files - Setting Path To Download Location

I've set set files to localhost an set the href links for the epub files.
<a href="more-utopia.epub" target="_blank"> more-utopia </a><br>
And I've try to browse from my custom web view but when I click to download the link, it appears no download and open the file in the browser with custom web view.

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView web = (WebView) findViewById(R.id.webview);
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://10.0.2.2/epub");
web.setWebViewClient(new myWebView());
} class myWebView extends WebViewClient{
@Override public boolean shouldOverrideUrlLoading(WebView view, String url) {
url = "http://10.0.2.2/epub/"; view.loadUrl(url); return true;
} }

What I want to do is to download the files and want to set path the download location to user selected location.
