Where is actual parameter are passed?

I am working in phonegap with android. I want to upload my file to my server. i have taken help from this link :- https://github.com/purplecabbage/phonegap-plugins/tree/master/Android/FileUploader

This is my fileupload.java code:

package com.beetight;

import com.phonegap.*;
import android.os.Bundle;

public class fileupload extends DroidGap {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.loadUrl("file:///android_asset/www/index.html");
    }
}

This is my fileuploader.java class:

package com.beetight;

This is my fileuploader.js:

FileUploader.prototype.uploadByUri = function(server, file, params, fileKey, fileName, mimeType, callback, fail) {

    return PhoneGap.exec(function(args) {
        callback(args);
    }, function(args) {
if(typeof fail == 'function') {
fail(args);
}
    }, 'FileUploader', 'uploadByUri', [server, file, params, fileKey, fileName, mimeType]);
};
FileUploader.prototype.upload = function(server, file, params, fileKey, fileName, mimeType, callback, fail) {

    return PhoneGap.exec(function(args) {
if(typeof callback == 'function') {
callback(args);
}
    }, function(args) {
if(typeof fail == 'function') {
fail(args);
}
    }, 'FileUploader', 'upload', [server, file, params, fileKey, fileName, mimeType]);
};


FileUploader.Status = {
PROGRESS: "PROGRESS",
COMPLETE: "COMPLETE"
}

PhoneGap.addConstructor(function() {
PhoneGap.addPlugin('fileUploader', new FileUploader());
PluginManager.addService("FileUploader","com.beetight.FileUploader");
});

This is my whole code.. but whenever i run this project then i does nothing. I dont know where should i pass actual parameter of my server name, file to which i want to upload on server. so please suggest me how can i give my servername and name of that file to which i want to upload on server. i am very fresher in phonegap programing. Thnak you in advance.

Given your code it expects something like

var uploader = FileUploader();
uploader.upload("http://yourserver-here.com", //<-- this is where you put your server
        "myfile.txt", //<-- The file you want to upload
        {} , //Not sure what this parameters is for, perhaps adding QS to server path
        "file", //Filekey, using the default from Fileuploader.java
        "myfile.txt", //filename
        "text/plain", //file mime-type
        function(args) {     //callback.
           alert("Callback"); //Not sure if this means success or if you have to check args
        },
        function(args) {     //callback on failure.
           alert("Failed");
        });
