Android使用Android Studio和PHP进行Wamp Server连接

I'm newbie here. I want to connect my android app to wampserver database. I found a tutorial on this link, But where should I find my serverUrl in wampserver? It should look like this: private final String serverUrl = "your path here" So where do I find "your path here"?

Here is my code:

MainActivity.java

package inducesmile.com.androidloginandregistration;

import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;
import org.json.JSONException;
import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;


public class MainActivity extends ActionBarActivity {

    protected EditText username;
    private EditText password;
    protected String enteredUsername;
    private final String serverUrl = "your path here";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        username = (EditText)findViewById(R.id.username_field);
        password = (EditText)findViewById(R.id.password_field);
        Button loginButton = (Button)findViewById(R.id.login);
        Button registerButton = (Button)findViewById(R.id.register_button);

        loginButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                enteredUsername = username.getText().toString();
                String enteredPassword = password.getText().toString();

                if(enteredUsername.equals("") || enteredPassword.equals("")){
                    Toast.makeText(MainActivity.this, "Username or password must be filled", Toast.LENGTH_LONG).show();
                    return;
                }
                if(enteredUsername.length() <= 1 || enteredPassword.length() <= 1){
                    Toast.makeText(MainActivity.this, "Username or password length must be greater than one", Toast.LENGTH_LONG).show();
                    return;

                // request authentication with remote server4
                AsyncDataClass asyncRequestObject = new AsyncDataClass();
                asyncRequestObject.execute(serverUrl, enteredUsername,     enteredPassword);

            }
        });

        registerButton.setOnClickListener(new View.OnClickListener() {

        int id = item.getItemId();

        //noinspection SimplifiableIfStatement

        return true;

    The "path" is probably the URL to your local web server, that is:

    http://your_ip/your_path_to_your_php_script
