Query a website like this:

Make your class implement AsyncTaskCompleteListenere<Boolean> by adding the following method to your class:

@Override
public void onTaskComplete(Boolean result) {
    Toast.makeText(getApplicationContext(), "URL Exist:" + result, Toast.LENGTH_LONG).show();
   // continue your job
}

Add a simple testConnection method to your class to be called when you want to check for your connectivity:

public void testConnection() {
        URLExistAsyncTask task = new URLExistAsyncTask(this);
        String URL = "http://www.google.com";
        task.execute(new String[]{URL});
    }

And finally the URLExistAsyncTask class which perform the connectivity test as an asynchronous (background) task and calls back your onTaskComplete method once done:

  public class URLExistAsyncTask extends AsyncTask<String, Void, Boolean> {
        AsyncTaskCompleteListenere<Boolean> callback;

        public URLExistAsyncTask(AsyncTaskCompleteListenere<Boolean> callback) {
            this.callback = callback;
        }

        protected Boolean doInBackground(String... params) {
            int code = 0;
            try {
                URL u = new URL(params[0]);
                HttpURLConnection huc = (HttpURLConnection) u.openConnection();
                huc.setRequestMethod("GET");
                huc.connect();
                code = huc.getResponseCode();
            } catch (IOException e) {
                return false;
            } catch (Exception e) {
                return false;
            }

            return code == 200;
        }

        protected void onPostExecute(Boolean result){
              callback.onTaskComplete(result);
        }
    }
