Android login dan registrasi dengan php mysql and sqlite

In my previous article Android Login and Registration Screen Design I explained designing the login and registration interfaces. But it has no real time functionality. In this tutorial I am going to explain how to build complete login and registration system in android using PHP, MySQL and SQLite. Also this tutorial covers how to build simple API using PHP and MySQL.

VIDEO DEMO

Below are the final outputs of this project.

Prerequisites

This tutorial is combination of few of my previous articles. Make sure you went through the below articles if you are very beginner.

1. Android working with Volley Library – Used to make HTTP calls.

2. Android Login and Registration Screen Design – Explained the designing of Login and Registration screens.

API (Application Programming Interface)

To interact with MySQL database we need to build a REST API first. REST Api job is to get the request from client, interact with database and finally give the response back to client. So we’ll create a simplePHP, MySQL API first. Our API do’s below jobs.

⇒ Accepts requests in GET/POST methods
⇒ Interact with database by inserting / fetching data.
⇒ Finally will give response back in JSON format

1. Downloading & Installing WAMP

Download & Install WAMP server from www.wampserver.com/en/. Once installed, launch the program from Start ⇒ All Programs ⇒ WampServer ⇒ StartWampServer. If you are on Mac, alternatively you can use MAMP for the same.

You can test your server by opening the address http://localhost/ in your browser. Also you can check phpmyadmin by opening http://localhost/phpmyadmin

Following is a screencast of Downloading and Installing WAMP Server.

2. Creating MySQL Database and Tables

Open phpmyadmin and execute below queries to create necessary database and table. Here we are creating only one table users to store users login information.

create database android_api /** CreatingDatabase **/

use android_api /** SelectingDatabase **/

create table database0

3. Creating PHP Project

Goto the location where wamp installed and open www folder. The default installation location of wamp would be C:/wamp. Below is the final PHP project structure we are going to create in this article.

1. Go into www folder and create a folder named android_login_api. This will be the root directory of our project.

2. In android_login_api, create another directory named include. In this folder, we keep all the helper classes.

3. Now inside include, create a php file named Config.php and add below content. Replace theDB_USER and DB_PASSWORD values with your’s.

Config.php

4. Create a class named DB_Connect.php in include and paste below code. In this class we handle opening and closing of database connection.

DB_Connect.php

5. Create DB_Functons.php inside include with below content. This file contains functions to store user in database, get user from database. You can also add methods like update user, delete user.

unique id – I am generating unique user id in php using uniqid(”, true) function. Sample user id will be like 4f074eca601fb8.88015924

Encrypted Password – The passwords are stored using base64_encode method. Each password needs two columns to store it in database. One is to store encrypted password and other is to storesalt used to encrypt the password.

3.1 Registration Endpoint

Now we have all the required classes ready. Let’s start creating the endpoint for user registration. This endpoint accepts name, email and password as POST parameters and store the user in MySQL database.

6. In android_login_api root directory, create register.php and below code.

register.php

3.2 Login Endpoint

Just like registration, we need to create another endpoint for login. This endpoint accepts email and password as POST parameters. After receiving the email and password, it checks in database for matched user. If the user is matched, it echoes the success the json response.

7. Create a php file named login.php inside android_login_api with the below content.

login.php

Now we have completed the PHP part. Let’s start the android part.

4. Creating the Android Project

The app we’re gonna build will have three simple screens Login Screen, Registration Screen and a welcome Dashboard Screen.

1. In Android Studio, create a new project from File ⇒ New Project and fill all the required details.

2. Create three packages named app, activity and helper under src folder.

3. Open build.gradle and add volley library support by adding
compile ‘com.mcxiaoke.volley:library-aar:1.0.0′ under dependencies.

6. Under app package create a class named AppConfig.java and add below code. In this class we declare the login and registration urls. While testing you need to replace the ip address with your localhost pc ip.

8. Now open AndroidManifest.xml and add INTERNET permission. Add the AppController class to<application> tag. Also add other activities (LoginActivity, RegisterActivity and MainActivity) which we are going to create shortly. I am keeping LoginActivity as launcher activity as it should be seen on app launch.

9. Under helper package, create a class named SessionManager.java and add below code. This class maintains session data across the app using the SharedPreferences. We store a boolean flagisLoggedIn in shared preferences to check the login status.

My previous article Android User Session Management using Shared Preferences gives you a good overview of managing the session data using SharedPreferences.

10. Under helper package, create a class named SQLiteHandler.java and paste the below code. This class takes care of storing the user data in SQLite database. Whenever we needs to get the logged in user information, we fetch from SQLite instead of making request to server.

Now if you run the app, you should see the login screen. But login might not work as we don’t have any user information in mysql database. That can be done by adding the registration screen.
