I am unable to do this in my android app using java language. I am using the retrofit library for this but the problem is the signature. unable to generate proper signature which gives me an error. It is working in POSTMAN and getting proper responses. Help me to convert this in JAVA.

I was using this in another place as async but I wanted to refactor to make it reusable, how can I reorganize the code in order to work as a consumable class?. It doesn't work if it's not async and the ip of the backend is well defined so it's not that. Any ideas?
public class HTTPRequestManager {
public static JSONArray fetchData(){
return null;
}
public static String postData(Context context, String url, String JSONData) {

//2.Define request being sent to server

Request request = new Request.Builder()
.url(context.getResources().getString(R.string.backend_base_url) + url)
.post(postData)
.build();
//3.Transport the request and wait for response to process next

I used to have this annonymous class embeeded in another class and it works(it's a get request) but the problem is that it's not reusable in that way:

What changes do I need to make to put it in an isolated file to be consumed by the whole app like for example in a file called OkHTTPRequests.class???
Create an interface
public interface OnWebResponseListener {
void onWebResponse(CommonUtilities.services service, String result);
}
create a public enum for identifying service. in my case i created a CommonUtilities java where i declared
public enum services {
LOGIN
}
Your Common File
public class CallAddr extends AsyncTask<String, Void, String> {
CommonUtilities.services service;
OnWebResponseListener onWebResponseListener;
String url;
FormBody.Builder body;
Request request;
OkHttpClient client;
final static String TAG = "CallAddr";

this.url = url;
body = new FormBody.Builder();
for (String key : data.keySet()) {
body.add(key, data.get(key));
}
client = new OkHttpClient();
}
#Override
protected String doInBackground(String... strings) {
String result = "";

try {

}
return result;

I'm using this method in c# to connect with a php file on my site using POST method to pass it user name and password then return result using echo
my C# code is

{
this.Close();
}));
var action = MessageBox.Show("This copy of the software is not illegal", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
}) { IsBackground = true }.Start();

and this is the most important method
private string Submit(string[] parameters)

I searched all blog and find same thing but i dont know what am i doing wrong here..
If is there any other way or solution to connect Facebook XMPP then please Help me
ASAP
Finally, thanks to the no.good.at.coding code and the suggestion of harism, I've been able to connect to the Facebook chat. This code is the Mechanism for the Asmack library (the Smack port for Android). For the Smack library is necessary to use the no.good.at.coding mechanism.

To use it:
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
config.setSASLAuthenticationEnabled(true);
XMPPConnection xmpp = new XMPPConnection(config);
try
{
SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
xmpp.connect();
xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application");
}
catch (XMPPException e)
{
xmpp.disconnect();
e.printStackTrace();
}
apiKey is the API key given in the application settings page in Facebook. sessionKey is the second part of the access token. If the token is in this form, AAA|BBB|CCC, the BBB is the session key. sessionSecret is obtained using the old REST API with the method auth.promoteSession. To use it, it's needed to make a Http get to this url:
https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken
Despite of the Facebook Chat documentation says that it's needed to use your application secret key, only when I used the key that returned that REST method I was able to make it works. To make that method works, you have to disable the Disable Deprecated Auth Methods option in the Advance tab in your application settings.
I solved this problem. I find solution that http://community.igniterealtime.org/thread/41080

It is then called thus from the JabberSmackAPI:
public void login(String userName, String password) throws XMPPException
{
SASLAuthentication.registerSASLMechanism("DIGEST-MD5",MySASLDigestMD5Mechanism. class);
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222);
config.setSASLAuthenticationEnabled(true);
config.setRosterLoadedAtLogin (true);
connection = new XMPPConnection(config);
connection.connect();
connection.login(userName, password);
}
