I am trying to connect my android app to the pandorabots server. I am using the following code in android:
package com.example.test2;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URI;
import java.net.URLEncoder;
public class Brain {
public String defaultCustid = "0";
public String custid = defaultCustid;
public String responseFailed = "RESPONSE FAILED";
public String defaultBotId = "da43c986ee34039e";
public String defaultHost = "www.pandorabots.com";
String botResponse;
public String askPandorabots(String input) {
return askPandorabots(input, defaultHost, defaultBotId);
}
public String askPandorabots(String input, String host, String botid) {
//System.out.println("Entering askPandorabots with input="+input+" host ="+host+" botid="+botid);
String responseContent = pandorabotsRequest(input, host, botid);
if (responseContent == null) return responseFailed;
else return pandorabotsResponse(responseContent, host, botid);
}
public String responseContent(String url) throws Exception {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
request.setURI(new URI(url));
InputStream is = client.execute(request).getEntity().getContent();
BufferedReader inb = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder("");
String line;
String NL = System.getProperty("line.separator");
while ((line = inb.readLine()) != null) {
sb.append(line).append(NL);
}
inb.close();
return sb.toString();
}
public String spec(String host, String botid, String custid, String input) {
//System.out.println("--> custid = "+custid);
String spec = "";
try {
if (custid.equals("0")) // get custid on first transaction with Pandorabots
spec = String.format("%s?botid=%s&input;=%s",
"http://" + host + "/pandora/talk-xml",
botid,
URLEncoder.encode(input, "UTF-8"));
else spec = // re-use custid on each subsequent interaction
String.format("%s?botid=%s&custid;=%s&input;=%s",
"http://" + host + "/pandora/talk-xml",
botid,
custid,
URLEncoder.encode(input, "UTF-8"));
} catch (Exception ex) {
ex.printStackTrace();
}
//System.out.println(spec);
return spec;
}
public String pandorabotsRequest(String input, String host, String botid) {
try {
String spec = spec(host, botid, custid, input);
//System.out.println("Spec = "+spec);
String responseContent = responseContent(spec);
return responseContent;
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}
public String pandorabotsResponse (String xmlRpcResponse, String host, String botid) {
try {
int n1 = xmlRpcResponse.indexOf("<that>");
int n2 = xmlRpcResponse.indexOf("</that>");
if (n2 > n1)
botResponse = xmlRpcResponse.substring(n1+"<that>".length(), n2);
n1 = xmlRpcResponse.indexOf("custid=");
if (n1 > 0) {
custid = xmlRpcResponse.substring(n1+"custid=\"".length(), xmlRpcResponse.length());
n2 = custid.indexOf("\"");
if (n2 > 0) custid = custid.substring(0, n2);
else custid = defaultCustid;
}
if (botResponse.endsWith(".")) botResponse = botResponse.substring(0, botResponse.length()-1); // snnoying Pandorabots extra "."
} catch (Exception ex) {
ex.printStackTrace();
}
return botResponse;
}
}
and this is my another class which I am using to display the user input and bot response,

}
else{

});
scv.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
public void onGlobalLayout() {
scv.post(new Runnable() {
public void run() {
scv.fullScroll(View.FOCUS_DOWN);
}
});
}
});
}
}
But i am getting a response failed error. I don’t know what is happeing. Can anyone help me?
