I am trying to get the JSON response from the Google Flight page.I looked into the following tutorial which explains how to get it link.So I created an HttpPost request in Android and added all the required headers I got from the Google chrome to emulate a request(I was inspecting the request/response in my chrome browser).My question is how do I get the JSON response back.Heres my code so far.
public class SearchScreen extends Activity {
private static final String URL = "http://www.google.com/flights/rpc";
//"www.google.com/flights/#search;f=SJC;t=EWR,JFK,LGA;d=2012-04-05;r=2012-04-12"
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_screen);
new AirplaneDetailsAsyncTask().execute(URL);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.search_screen, menu);
return true;
}
private class AirplaneDetailsAsyncTask extends
AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpResponse response;
HttpPost post = new HttpPost(urls[0]);
try {
post.setEntity(new StringEntity(streamToString(getAssets().open("json_payload.txt"))));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
