HTTP Android

Hi,

I'm trying to port this functionality to android and I couldn't find anything on the forums or by searching, other than that contributed library processing.net hadn't been ported yet?

Basically I would like to get a string of xml returned from a twitter search so that I can do stuff with it (e.g count the number of tweets within 1 mile of the phone - using the phones gps or what ever).

I started writing a post requesting help but found this which slightly modified works as a class in Processing Android mode, see the following (written with a lot of help from MarkSelby) - it prints html in my phones screen. Thought the code might be useful to others.

Oh and don't forget to turn INTERNET permission on.

In first Tab:
2. // Android fonts
3. String[] fontList;
4. PFont androidFont;
6. Aclient html;
8. void setup() {
9. html = new Aclient();
10. size(480, 640, A2D);
12. orientation(PORTRAIT);
14. fontList = PFont.list();
15. androidFont = createFont(fontList[0], 12, true);
16. textFont(androidFont);
17. }
19. void draw() {
20. try{
21. String data = html.executeHttpGet();
22. text(data);
23. }
24. catch (java.lang.Exception JLE) {
25. println("JLE: "+JLE);
26. exit();
27. }
28. noLoop();
29. }
And in second tab called "Aclient"
2. import java.io.IOException;
3. import java.io.InputStreamReader;
4. import java.net.URI;
5. import org.apache.http.HttpResponse;
6. import org.apache.http.client.HttpClient;
7. import org.apache.http.client.methods.HttpGet;
8. import org.apache.http.impl.client.DefaultHttpClient;
9. public class Aclient {
10. public String executeHttpGet() throws Exception {
11. BufferedReader in = null;
12. try {
13. HttpClient client = new DefaultHttpClient();
14. HttpGet request = new HttpGet();
15. request.setURI(new URI("http://www.processing.org/"));
16. HttpResponse response = client.execute(request);
17. in = new BufferedReader
18. (new InputStreamReader(response.getEntity().getContent()));
19. StringBuffer sb = new StringBuffer("");
20. String line = "";
21. String NL = System.getProperty("line.separator");
22. while ((line = in.readLine()) != null) {
23. sb.append(line + NL);
24. }
25. in.close();
26. String page = sb.toString();
27. System.out.println(page);
28. return page;
29. } finally {
30. if (in != null) {
31. try {
32. in.close();
33. } catch (IOException e) {
34. e.printStackTrace();
35. }
36. }
37. }
38. }
39. }

HTTP GET requests - strange results

I'm trying the Networking example and I'm getting strange results. Ultimately I simply want to return a twitter search query which there searchAPI says you can get with a simple HTTP GET on say http://search.twitter.com/search.atom?q=Nottingham and indeed you get a nice string of XML in a browser with this URL.

However, I'm getting a strange return on www.processing.org. Running:
1. import processing.net.*;
3. Client c;
4. String data;
6. void setup() {
7. size(200, 200);
8. background(50);
9. fill(200);
10. c = new Client(this, "www.processing.org", 80); // Connect to server on port 80
11. c.write("GET / HTTP/1.1\r\n"); // Use the HTTP "GET" command to ask for a Web page
12. c.write("Host: 82.69.234.94\n\n"); // Be polite and say who we are
13. }
15. void draw() {
16. if (c.available() > 0) { // If there's incoming data from the client...
17. data = c.readString(); // ...then grab it and print it
18. println(data);
19. }
20. }
Returns

HTTP/1.1 200 OK

WHich is not what I was expecting. And when I run
1. search.twitter.com/search.atom?q=Nottingham
I get
java.net.UnknownHostException: search.twitter.com/search.atom?q=Nottingham

And a whole load more error lines.

I'm behind a domestic router which has the external IP 82.69.234.94 and my laptop is on 192.168.2.17 behind that router. I've tried on processing 1.2.1 and dev 0194, same results. Running Ubuntu with java 6...
