try {
            HttpClient client = new DefaultHttpClient();  
            String getURL = "http://www.google.com";
            HttpGet get = new HttpGet(getURL);
            HttpResponse responseGet = client.execute(get);  
            HttpEntity resEntityGet = responseGet.getEntity();  

            if (resEntityGet != null) {  
            Toast.makeText(getApplicationContext(), "ok", Toast.LENGTH_LONG).show();
             }
    } catch (Exception e) {
        //e.printStackTrace();
        Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_LONG).show();

Answer

seems to be like you are trying to make an http request in the UI thread.

put your request in another thread.
