Question

I’m running an android app that displays a webview on specific URL, I want to check if the application server I’m accessing is alive and that I can view HTML, if failed I should terminate the webview, this check should be every 10 seconds (or whatever), what is the best approach for this ?

Answer 1

Create Timer (here you have information) and when timer tick, ping any host :

 URL url = new URL("http://microsoft.com");

    HttpURLConnection urlc = (HttpURLConnection) url.openConnection();
    urlc.setRequestProperty("User-Agent", "Android Application:"+Z.APP_VERSION);
    urlc.setRequestProperty("Connection", "close");
    urlc.setConnectTimeout(1000 * 30); // mTimeout is in seconds
            urlc.connect();
    if (urlc.getResponseCode() == 200) {
        Main.Log("getResponseCode == 200");
            return new Boolean(true);
    }
    } catch (MalformedURLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
} catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
    } 

If return true : connection is active. Else isn’t active.
