Android Login And Registration Example With PHP MySQL Session Management

Hello, geeks. Welcome to Android login and Registration example.

I have found many tutorials covering Android login and Registration, but there are few issues. Some tutorial covers only registration part. Some may cover only login part.

If there is any example which covers both Android login and Registration, then it is not maintaining login session.

Maintaining login session is the most important part of whole professional login scenario.

So I decided to cover all below scenarios.

1. Register user and upload his information to the server using PHP and MySQL.
2. Login user and maintain session until he clicks on logout button.

So at the end of the register and login in Android example, you will get all the things needed for maintaining professional login session.

You will also get the professional format to call remote Web Services in proper and easiest way at the end of Android login and Registration example.

You may find this tutorial little lengthy but once you give it 10 minutes, you will be able to call all web services easily in all your future apps.

First, check the output of Android login and Registration tutorial, then we will create it.

Layout Previews

Wait for a second

We will use JSON Parsing in this tutorial.

If you don’t know how to parse JSON, then check JSON Parsing In Android tutorial first.

Download Source Code for Android login and Registration

Creating Android login and Registration Tutorial step by step

Step 1: Creating a PHP file for registration

Create a new PHP file named “config.php” and add below

Create a new PHP file and name it “simpleregister.php”

Add below code in it

Step 2: Creating a PHP file for login

Create a new PHP file and name it “simplelogin.php”

Add below code in it

PHP Directory

Make sure that all three PHP files are in the same folder.

My all files are in the “Tennis” folder as below image.

PHP part is over. Now come to Android Studio and create a new project.

Step 3: Updating AndroidManifest.xml file

Note: If you are targeting SDK version above 22 (Above Lollipop) then you need to ask a user for granting runtime permissions. Check marshmallow runtime permission for more information.

Final code for AndroidManifest.xml file

Step 4: Adding common classes into project

We will add common classes which contain public constant variables and public methods.

We can use these variables and methods anywhere in the project so that it will reduce data redundancy.

That means we will write them only once and then we will use them anytime and anywhere when needed.

Names of the classes are:

1. PreferenceHelper
2. AndyConstants
3. AndyUtils
4. HttpRequest
5. ParseContent

Step 5: Making PreferenceHelper

Create a new Java class and add below code

We use this class to save some information (name, hobby, a user is login or logout?, etc.) in SharedPreferences.

All methods starting with put is used to save information.

All methods starting with get is used to get saved information.

Step 6: Creating AndyConstants

Create a new Java class and copy following source code

AndyConstants class contain URL constants and Parameter constants.

Step 7: Preparing AndyUtils

Create a Java class named AndyUtils and add following source code

This class contains a methods to show( showSimplrProgressDialog() ) and remove( removeSimpleProgressDialog() ) progress dialog when app is fetching JSON data from server.

AndyUtils also includes a method ( isNetworkAvailable() ) to check whether the Internet of Android device is on or off.

Step 8: Preparing HttpRequest Class

Make new Java class named HttpRequest and add following source code

We use methods of this class to establish a connection between an Android device and web server.

Step 9: Creating ParseContent

Open new Java class named ParseContent, then paste below source code

In above source code, isSuccess(String response) method is used to check whether a status of response is true or false.

getErrorCode(String response ) method is used to get the message of JSON data.

saveInfo(String response) method will parse JSON data. I will describe this method later.

Step 10: Creating WelcomeActivity

Create a new activity named WelcomeActivity.

Add following into activity_welcome.xml

Add following into WelcomeActivity.java

Step 11: Preparing LoginActivity

Make a new activity named LoginActivity.

Paste below source code into activity_login.xml

Source code for LoginActivity.java

Describing above class

Look at login() method

HashMap contains parameters of Web Service. Below is HashMap.

Following source code will call web service.

After getting JSON response in String format, onPostExecute() method is called and from it onTaskCompleted() method is called.

Below is a source code for onTaskCompleted() method.

parseContent.saveInfo() will save information in SharedPreference.

Source code for saveInfo() method is as following

Here we parse JSON Data.

JSON Data will look like below

Look in saveInfo() method.

We have parsed JSONObject by below

In JSON, a key “data” starts with JSONArray “[” so it is parsed by below line

hobby, name, etc. information is parsed in “for” loop and it is stored using preferenceHelper as per following.

Step 12: Preparing MainActivity

Add below code into activity_main.xml

Logic to register a user is written in MainActivity. So add below source code in MainActivity.java

In register() method, Web Service is called same as we did in LoginActivity.

Just URL of service and parameters are different.

So finally after doing all above stuff, now you have a complete professional format to make an international Android app.

If you follow this professional format, not only register and login but you can call all other web services very easily.

That’s all for Android login and Registration example.

Feel free to put your queries and reviews in the comment section. Thank you 🙂

Am following this example for my login but using asp.net endpoint http://197.232.17.86/MjaliAPP/UserLogin
with parameters username and password. When i use this endpoint its not parsing the parameters to the url. Please help

Hi thanks for the Android Login And Registration Example With PHP MySQL Session Management tutorial, kudos to you. Is there a way to prevent a user from using another persons
crdentials i.e preventing user A from using user B credentials on his unless he registers. Is there a way
to make the password locked to phone number or imei of a device. If the user B wants to use user A password
the app should prompt or show dialog “password already in use by another user”. Kindly help

I have made similar restriction for username. UserA can not use username of UserB. You can make restriction for password also.You just need to change simpleregister.php file.

Thanks for your response can you enlighten me on how you did your restriction for usernames

thanx a lot for your help.can i get code for json_parsing.php. After entering data in login form and submit i get message no data.can you help me whats wrong?

Code for json_parsing.php

0) <
while ($row = mysqli_fetch_assoc($result)) <
$emparray[] = $row;
>
>
echo json_encode(array( “status” => “true”,”message” => “Data fetched successfully!”,”data” => $emparray) );
?>

Why does one need every user to have unique password? but then you can
1. Before inserting the user in ur database first select in the database. check using
$pass=mysqli_escape_string($conn,$_POST[‘password’]);;
$result=select * from users where password =’”.$pass.”‘;
if(mysqli_num_rows($results)>0). <
echo”Password is already in use”;
>else <
//put on your registration code here
>

I don’t tthink it practically make sense though to make a unique password, it I think username its fine.

I really appreciate you response can i implement these for username instead as you suggested

Hello can you tell me how can i run another activity after login ?
please help as fast you can thanks.

I have already started WelcomeActivity when user successfully login. Edit there with your activity.

Hello, Thank you for sharing these sketches, I am new to android programming, I have just copied the files you have posted and modified the variables to match my requirement, but when I test the login page by try to login it just load for some seconds, like 15 sec, finally toasts a message says “No data” where by I expected “Wrong username or password”. where could I have mess-up?

In addition, I can see on your PHP files directory, in Tennis folder, you have a file named “json_parsing.php” what is the content of this file? and what does it do? I don’t have it in my directory, could it be the source of my problem?, Please help.
Thank you.

Check your logcat. What messages it shows? I think you are doing some mistake in parsing JSON data. Check if logcat giving error relating to JSON or not?

Yes, I have this error in logcat, org.json.JSONException: Value failed of type java.lang.String cannot be converted to JSONObject. How do I get out of this error please.

And json_parsing.php file have nothing to relate with this tutorial. This file is used in JSON Parsing tutorial at here : http://demonuts.com/2017/04/20/json-parsing-in-android-studio-from-url/

hello please samuel is my name when i search records it say no data i dont no reason why

Have you got solution on the no data,

I also receive the same thing i can point out why.

do you have any sample for a restriction? where you cant login after registering, it needs some approval first from the admin. and when the admin approves the user the user will be notify via email, that the account has been activated. Thanks 🙂

When I try to log in it says no data How to Fix this?

in onTaskComplete() method, there is a line to print response in logcat

Can you tell me what response are you getting in your logcat?

Value http of type java.lang.String cannot be converted to JSONObject

hello, can I recode your code to kotlin, or do you have already one?

I have not done it yet, you can use it in your personal project but can not publish it on any blog or website.

Great Tutorial…Excellent, very professional … I am trying to develop a mobile app and a website but my skills are not enough to code all that I wish to. Could we talk about the terms you might be get on this project or hired somewhat?
