    You should use Get request instead of POST request.

    public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //make async request 
    new myAsynctask().execute();
}

//********************************************
//get json string
public String getJSONString() {
    StringBuilder builder = new StringBuilder();
    HttpClient client = new DefaultHttpClient();

    String urlString="http://www.ajax.googleapis.com/ajax/services/search/local?v=1.0&q=restaurants&rsz=8&sll=-27.5595451,-48.6206452&radius=1000&output=json";

    HttpGet httpGet = new HttpGet(urlString);
    try {
        HttpResponse response = client.execute(httpGet);
        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        if (statusCode == 200) {
            HttpEntity entity = response.getEntity();
            InputStream content = entity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(content));
            String line;
            while ((line = reader.readLine()) != null) {
                builder.append(line);
            }
        } else {
            Log.e(getClass().getSimpleName(), "Failed to download json response");
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return builder.toString();
}
//********************************************
private class myAsynctask extends AsyncTask<Void, Void, String>{

    @Override
    protected String doInBackground(Void... params) {

        String jsonString=getJSONString();
        return jsonString;
    }
    @Override
    protected void onPostExecute(String jsonString) {
        super.onPostExecute(jsonString);
        Log.e(getClass().getSimpleName(), jsonString);
    }
}

    }
