Android Volley Tutorial - User Registration and Login

Hey folks, heres another Android Volley Tutorial. If you remember one of remember one of the previous tutorial which was about creating a Login and Registration system for Android. You can check the post from below.

Android Login and Registration using PHP MySQL

In the above mentioned tutorial we learnt how to send http request to our web services to make login and registration system. In this post we will do exactly the same thing but with Volley Library. Using volley library will simplify our task, and it is fast and it manages everything so you don’t need to worry. So lets start this Android Volley Tutorial.

Android Volley Tutorial – User Registration and Login

Creating Web Services

So first we need the Web Services for User Registration and Login. We also need MySQL Database. Now you can use other technologies for your server side as well. It is obvious not mandatory to use PHP and MySQL only. But here I am using PHP and MySQL.
And the best thing here is I will not be doing this thing in this post hahaha 😛 (LOL). Because in the last post which you can see from the below link, we already built web services for the User Registration and Login. And here I will be using the same thing. So go through the link given below first then move further in this post.

Android Login and Registration

Creating a new Project

As always we need a new Android Studio project. So create a project named SimplifiedCoding (You can actually name it whatever you want) with an EmptyActivity.
Once your project is loaded create two more activities here named LoginActivity and ProfileActivity.
Now lets design the screens first.

User Interface Design

Registration Screen

So come inside activity_main.xml and write the following xml code.

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context="net.simplifiedlearning.simplifiedcoding.MainActivity">

<LinearLayout

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_centerVertical="true"

android:orientation="vertical"

android:padding="10dp">

<EditText

android:id="@+id/editTextUsername"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:hint="Username"

android:inputType="text" />

<EditText

android:id="@+id/editTextEmail"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:hint="Email"

android:inputType="textEmailAddress" />

<EditText

android:id="@+id/editTextPassword"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:fontFamily="sans-serif"

android:hint="Password"

android:inputType="textPassword" />

<RadioGroup

android:id="@+id/radioGender"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:orientation="horizontal">

<RadioButton

android:id="@+id/radioButtonMale"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:checked="true"

android:text="Male" />

<RadioButton

android:id="@+id/radioButtonFemale"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Female" />

</RadioGroup>

<Button

android:id="@+id/buttonRegister"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:text="Register" />

<TextView

android:id="@+id/textViewLogin"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:text="Already Registered?\nLogin Here"

android:textAlignment="center"

android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium" />

</LinearLayout>

<ProgressBar

android:visibility="gone"

android:id="@+id/progressBar"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_centerVertical="true" />

</RelativeLayout>

You will see the following design with the above given xml code.

Login Screen

For the login screen come inside activity_login.xml and write the following xml code.

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context="net.simplifiedlearning.simplifiedcoding.LoginActivity">

<LinearLayout

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_centerVertical="true"

android:orientation="vertical"

android:padding="10dp">

<EditText

android:id="@+id/editTextUsername"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:hint="Username"

android:inputType="text" />

<EditText

android:id="@+id/editTextPassword"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:fontFamily="sans-serif"

android:hint="Password"

android:inputType="textPassword" />

<Button

android:id="@+id/buttonLogin"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:text="Login" />

<TextView

android:id="@+id/textViewRegister"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"

android:layout_marginTop="8dp"

android:text="Dont' have an account?\nRegister Here"

android:textAlignment="center"

android:textAppearance="@style/Base.TextAppearance.AppCompat.Medium" />

</LinearLayout>

<ProgressBar

android:visibility="gone"

android:id="@+id/progressBar"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_centerVertical="true" />

</RelativeLayout>

The above code will generate the output as shown below.

Profile Screen

Lastly we will design the profile screen using the following xml code.

<LinearLayout

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="vertical">

<TableLayout

android:layout_width="match_parent"

android:layout_height="wrap_content">

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:padding="10dp"

android:text="probelalkhan@gmail.com"

android:textAppearance="@style/Base.TextAppearance.AppCompat.Large" />

</TableRow>

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:padding="10dp"

android:text="Gender"

android:textAppearance="@style/Base.TextAppearance.AppCompat.Large" />

<TextView

android:id="@+id/textViewGender"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:padding="10dp"

android:text="Male"

android:textAppearance="@style/Base.TextAppearance.AppCompat.Large" />

</TableRow>

</TableLayout>

<Button

android:id="@+id/buttonLogout"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:text="Logout" />

</LinearLayout>

</RelativeLayout>

You will see the profile screen looking as shown below.

Creating Helper Classes

It is very important that we organize our code well so that it can be reused. That is why here we are creating different classes for different task. Though we are doing exactly the same we did in the last post.

User Model Class

First we will create a class for our User. So create a class named User.java and write the following code inside. The code contains nothing but only the user attributes with a constructor and getters. You can easily do this by right click -> generate -> constructor/ getters.

package net.simplifiedlearning.simplifiedcoding;

/**

* Created by Belal on 9/5/2017.

//this is very simple class and it only contains the user attributes, a constructor and the getters

// you can easily do this by right click -> generate -> constructor and getters

public class User {

private int id;

private String username, email, gender;

public User(int id, String username, String email, String gender) {

this.id = id;

this.username = username;

this.email = email;

this.gender = gender;

}

public int getId() {

return id;

}

public String getUsername() {

return username;

}

public String getEmail() {

return email;

}

public String getGender() {

return gender;

}

SharedPrefManager Class

In android side to maintain a user login session, here we are using SharedPreferenes. Inside SharedPreferences we will store the data of currently logged in user. So that we can use it in our application. So to handle all the sharedpreferences task at one place we are having this class named SharedPrefmanager.java.

package net.simplifiedlearning.simplifiedcoding;

import android.content.Context;

import android.content.Intent;

import android.content.SharedPreferences;

/**

* Created by Belal on 9/5/2017.

//here for this class we are using a singleton pattern

public class SharedPrefManager {

//the constants

private static final String SHARED_PREF_NAME = "simplifiedcodingsharedpref";

private static final String KEY_USERNAME = "keyusername";

private static final String KEY_EMAIL = "keyemail";

private static final String KEY_GENDER = "keygender";

private static final String KEY_ID = "keyid";

private static SharedPrefManager mInstance;

private static Context mCtx;

private SharedPrefManager(Context context) {

mCtx = context;

}

public static synchronized SharedPrefManager getInstance(Context context) {

if (mInstance == null) {

mInstance = new SharedPrefManager(context);

}

return mInstance;

}

//method to let the user login

//this method will store the user data in shared preferences

public void userLogin(User user) {

SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);

SharedPreferences.Editor editor = sharedPreferences.edit();

editor.putInt(KEY_ID, user.getId());

editor.putString(KEY_USERNAME, user.getUsername());

editor.putString(KEY_EMAIL, user.getEmail());

editor.putString(KEY_GENDER, user.getGender());

editor.apply();

}

//this method will checker whether user is already logged in or not

public boolean isLoggedIn() {

SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);

return sharedPreferences.getString(KEY_USERNAME, null) != null;

}

//this method will give the logged in user

public User getUser() {

SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);

return new User(

sharedPreferences.getInt(KEY_ID, -1),

sharedPreferences.getString(KEY_USERNAME, null),

sharedPreferences.getString(KEY_EMAIL, null),

sharedPreferences.getString(KEY_GENDER, null)

);

}

//this method will logout the user

public void logout() {

SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);

SharedPreferences.Editor editor = sharedPreferences.edit();

editor.clear();

editor.apply();

mCtx.startActivity(new Intent(mCtx, LoginActivity.class));

}

Web Service URLs

Create a new class named URLs.java to put all the Web Service URLs at one place. So here I am using a class named URLs.java.

package net.simplifiedlearning.simplifiedcoding;

/**

* Created by Belal on 9/5/2017.

public class URLs {

private static final String ROOT_URL = "http://192.168.101.1/Android/Api.php?apicall=";

public static final String URL_REGISTER = ROOT_URL + "signup";

public static final String URL_LOGIN= ROOT_URL + "login";

}

Now we have all the helper classes.

Adding Volley Library

As in this project we need to use Volley for the network operation, and for this we need to add Volley to this project.
For this come inside app level build.gradle file and inside dependencies block add volley.

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

exclude group: 'com.android.support', module: 'support-annotations'

})

//adding volley with this line

compile 'com.android.volley:volley:1.0.0'

compile 'com.android.support:appcompat-v7:26.+'

compile 'com.android.support.constraint:constraint-layout:1.0.2'

testCompile 'junit:junit:4.12'

}

After adding this you need to sync your project.

Adding Internet Permission

As networking operations requires internet permission so inside AndroidManifest.xml define the internet permission for the application.

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="net.simplifiedlearning.simplifiedcoding">

<uses-permission android:name="android.permission.INTERNET" />

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:roundIcon="@mipmap/ic_launcher_round"

android:supportsRtl="true"

android:theme="@style/AppTheme">

<intent-filter>

</intent-filter>

</activity>

</application>

</manifest>

Using Singleton Pattern for Volley

As any app requires many network operations. So in this case it is always a good idea to use a single instance of Volley RequestQueue. For this we will use a Singleton Pattern for handling all the request queues.
So create a new class named VolleySingleton.java and write the following code.

package net.simplifiedlearning.simplifiedcoding;

import android.content.Context;

import com.android.volley.Request;

import com.android.volley.RequestQueue;

import com.android.volley.toolbox.Volley;

/**

* Created by Belal on 9/5/2017.

public class VolleySingleton {

private static VolleySingleton mInstance;

private RequestQueue mRequestQueue;

private static Context mCtx;

private VolleySingleton(Context context) {

mCtx = context;

mRequestQueue = getRequestQueue();

}

public static synchronized VolleySingleton getInstance(Context context) {

if (mInstance == null) {

mInstance = new VolleySingleton(context);

}

return mInstance;

}

public RequestQueue getRequestQueue() {

if (mRequestQueue == null) {

// getApplicationContext() is key, it keeps you from leaking the

// Activity or BroadcastReceiver if someone passes one in.

mRequestQueue = Volley.newRequestQueue(mCtx.getApplicationContext());

}

return mRequestQueue;

}

public <T> void addToRequestQueue(Request<T> req) {

getRequestQueue().add(req);

}

User Registration

Now lets perform the user registration inside MainActivity.java. The code is very simple and it is actually explaining itself. But if you think you have some confusions at some lines, feel free to comment and I will try to help you.

return params;

}

};

VolleySingleton.getInstance(this).addToRequestQueue(stringRequest);

}

If you are facing some problem understanding the codes, you can check the video tutorials given at the starting of this post.

User Profile

Come inside ProfileActivity.java and write the following code. Here we are only displaying the User data and we have a button that will let the user logout from the app.

package net.simplifiedlearning.simplifiedcoding;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.TextView;

public class ProfileActivity extends AppCompatActivity {

TextView textViewId, textViewUsername, textViewEmail, textViewGender;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_profile);

//if the user is not logged in

//starting the login activity

if (!SharedPrefManager.getInstance(this).isLoggedIn()) {

finish();

startActivity(new Intent(this, LoginActivity.class));

}

textViewId = (TextView) findViewById(R.id.textViewId);

textViewUsername = (TextView) findViewById(R.id.textViewUsername);

textViewEmail = (TextView) findViewById(R.id.textViewEmail);

textViewGender = (TextView) findViewById(R.id.textViewGender);

//getting the current user

User user = SharedPrefManager.getInstance(this).getUser();

//setting the values to the textviews

textViewId.setText(String.valueOf(user.getId()));

textViewUsername.setText(user.getUsername());

textViewEmail.setText(user.getEmail());

textViewGender.setText(user.getGender());

//when the user presses logout button

//calling the logout method

findViewById(R.id.buttonLogout).setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

finish();

SharedPrefManager.getInstance(getApplicationContext()).logout();

}

});

}

Now lastly we will code the LoginActivity.

User Login

Come inside LoginActivity.java and write the following code. It is almost same as the User Registration Activity (MainActivity.java).
