My http get Android Java Code:

public void postData() {

        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet("http://www.xxxx.com/mobile/xxx/save.php?text=sdf"); 

        // replace with your url
        HttpResponse response;
        try {
            response = client.execute(request);

            Log.d("Response of GET request", response.toString());
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

I hope you can help me and I apologize for my bad english. Why do we have to write as much text here, I do not know what to write.

This exception is thrown when an application attempts to perform a networking operation on its main thread. Run your code in AsyncTask

For more info see android NetworkOnMainThreadException

Run your code in asyntask or a different thread you can't make a network request on your main thread.
