Introduction :
In the digital age, educational application plays a vital role for both learners and educators. Creating a basic multiple choice question (MCQ) app connected to a local server (wampserver) using Android Studio IDE is a very interesting and educational project for Android app developer.
This dynamic MCQ app is based on server-client communication program that connect to WampServer. Building a simple MCQ app using Android Studio is helpful for student as well as teacher in the learning process. Such educational tools or application is useful for various educational purposes like quiz, online-exam etc.
In this article, I shall show you how to create a Multiple Choice Question (MCQ) app connected to a local server (WampServer) using Android Studio. You have to implement HTTP requests in the MCQ app to communicate with the local server (wampserver). Here, I use volley library to connect MCQ app to the local server (wampserver).Using php language, you can send and receive data (questions) between the app and the wampserver.
About the application :
This is a simple MCQ app which connects to a local server (wampServer). Actually, the app is for both student and teacher. When you open the app on your phone, you can see two buttons on the screen. One for student and other for teacher.
When you click on student button, the app will dynamically fetch questions and answer choices from a local server (wampServer). After that, the app displays the question and answer choices to the student for submitting their answer. Then, the submitted answer will be stored in server (wampServer) database.
When you click on teacher button, you can see four buttons by which you can add new questions, update old questions, see all questions with answers and also see students given answer with their name.
In the app, I have shown only 10 questions in student section. You can change as you like. You can also use a remote server (VPS) instead of the local server (wampServer) for this MCQ app. You have to set up the remote server (VPS) for this purpose.
Step for create the application :
Before creating the MCQ app, you have to install Android Studio IDE on your pc. If you do not know how to build an Android app on Android Studio IDE, you can follow the link. After that, you have to install and set up a local server (wampserver) on your pc to handle backend operations.
You can also google search for connect a phone to local server (wampserver) of your pc. You have to follow the below step to build the multiple choice question (MCQ) app.
Step 1 :
First, create a new project “MCQ_app” with empty activity and check on legacy android.support libraries.
Step 2 :
When the app will be build, open manifest file and add the following code before application tag.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
After that, add the below code in between application tag.
android:usesCleartextTraffic="true"Step 3 :
Now, paste the code in dependencies of build.gradle(module.app) then click on “Sync Now” with net is on your pc.
implementation 'com.android.volley:volley:1.1.0'The dependencies look like below code.
dependencies {
implementation 'com.android.support.constraint:constraint-layout:2.0.4'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.volley:volley:1.1.0'
}Step 4 :
Then, create a folder or directory in the res folder and name it “raw”. Here, you have to paste two file aa.m4a and bb.m4a. The two files are sound files which tell you student answer is right or not. It is optional. You can avoid this step.
Step 5 :
Now, open MainActivity.java file and replace the following code.
package com.example.mcq_app;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void student(View view) {
Intent intent=new Intent(MainActivity.this,MainActivity2.class);
startActivity(intent);
}
public void teacher(View view) {
Intent intent=new Intent(MainActivity.this,MainActivity3.class);
startActivity(intent);
}
}Now, open activity_main.xml file and replace the following code.

public String ANS3;
public String ANS4;
public String ANS5;
public String ANS6;
public String ANS7;
public String ANS8;
public String ANS9;
public String ANS10;
}Step 20 :
After creating all files and paste the code, open wampserver on your pc. Here, you have to create a database named “kritika”. Now create two table “moc1” and “student”. In “moc1” table create the column id, question, ans1, ans2, ans3, ans4 and ansright. In “student” table create the column id, name, que1, que2, que3, que4, que5, que6, que7, que8, que9, que10.
Now, you have to open www folder of File Explorer. In C:\wamp64\www folder you have to paste the following php files. First create insertname.php and paste the below code.
<?php
$HostName = 'localhost:3308';
$HostUser = 'root';
$HostPass = '';
$DatabaseName = 'kritika';
$con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);
$name = $_POST['name'];
$ans1 = $_POST['que1'];
$ans2 = $_POST['que2'];
$ans3 = $_POST['que3'];
$ans4 = $_POST['que4'];
$ans5 = $_POST['que5'];
$ans6 = $_POST['que6'];
$ans7 = $_POST['que7'];
$ans8 = $_POST['que8'];
$ans9 = $_POST['que9'];
$ans10 = $_POST['que10'];
$result1 = $con->query("SELECT name FROM student WHERE name = '$name'");
$row_count = $result1->num_rows;
if($row_count == 1)
{
echo 'User exists';
}
else
{
$Sql_Query = "INSERT INTO student (name,que1,que2,que3,que4,que5,que6,que7,que8,que9,que10) values
('$name','$ans1','$ans2','$ans3','$ans4','$ans5','$ans6','$ans7','$ans8','$ans9','$ans10')";
if($con->query($Sql_Query) === TRUE){
echo 'login Successfully';
}
else{
echo 'error';
}
}
mysqli_close($con);
?>Step 21 :
Create showdata.php and paste the below code.
<?php
$HostName = 'localhost:3308';
$HostUser = 'root';
$HostPass = '';
$DatabaseName = 'kritika';
$con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
$sql = "SELECT * FROM moc1";
$result = $con->query($sql);
if ($result->num_rows >0) {
while($row[] = $result->fetch_assoc()) {
$tem = $row;
$json = json_encode($tem);
}
} else {
echo "No Results Found.";
}
echo $json;
$con->close();
?>Step 22 :
Create data.php and paste the below code.
<?php
$HostName = 'localhost:3308';
$HostUser = 'root';
$HostPass = '';
$DatabaseName = 'kritika';
$con = mysqli_connect($HostName,
$HostUser,$HostPass,$DatabaseName);
$ques = $_POST['question'];
$ans1 = $_POST['ans1'];
$ans2 = $_POST['ans2'];
$ans3 = $_POST['ans3'];
$ans4 = $_POST['ans4'];
$ansright = $_POST['ansright'];
$Sql_Query = "INSERT INTO moc1
(question,ans1,ans2,ans3,ans4,ansright)
values
('$ques','$ans1','$ans2','$ans3','$ans4','$ansright')";
if($con->query($Sql_Query) === TRUE){
echo 'Question Inserted on server Successfully';
}
else{
echo "Something went wrong";
}
mysqli_close($con);
?>Step 23 :
Create update.php and paste the below code.
<?php
$HostName = 'localhost:3308';
$HostUser = 'root';
$HostPass = '';
$DatabaseName = 'kritika';
$con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);
$id=$_POST['id'];
$ques = $_POST['question'];
$ans1 = $_POST['ans1'];
$ans2 = $_POST['ans2'];
$ans3 = $_POST['ans3'];
$ans4 = $_POST['ans4'];
$ansright = $_POST['ansright'];
$Sql_Query = "UPDATE moc1 SET question='$ques',ans1='$ans1',ans2='$ans2',ans3='$ans3',ans4='$ans4',ansright='$ansright' WHERE id = $id";
if($con->query($Sql_Query) === TRUE){
echo 'Question updated Successfully';
}
else{
echo "Something went wrong";
}
mysqli_close($con);
?>Step 24 :
Create showanswer.php and paste the below code.
<?php
$HostName = 'localhost:3308';
$HostUser = 'root';
$HostPass = '';
$DatabaseName = 'kritika';
$con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
$sql = "SELECT * FROM student";
$result = $con->query($sql);
if ($result->num_rows >0) {
while($row[] = $result->fetch_assoc()) {
$tem = $row;
$json = json_encode($tem);
}
} else {
echo "No Results Found.";
}
echo $json;
$con->close();
?>Step 25 :
Create insertanswer1.php and paste the below code.
<?php
$HostName = 'localhost:3308';
$HostUser = 'root';
$HostPass = '';
$DatabaseName = 'kritika';
$con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);
$name = $_POST['name'];
$ans1 = $_POST['que1'];
$ans2 = $_POST['que2'];
$ans3 = $_POST['que3'];
$ans4 = $_POST['que4'];
$ans5 = $_POST['que5'];
$ans6 = $_POST['que6'];
$ans7 = $_POST['que7'];
$ans8 = $_POST['que8'];
$ans9 = $_POST['que9'];
$ans10 = $_POST['que10'];
$Sql_Query = "UPDATE student SET
name='$name',que1='$ans1',que2='$ans2',que3='$ans3',que4='$ans4',que5='$ans5',que6='$ans6',que7='$ans7',que8='$ans8',que9='$ans9',que10='$ans10' where name='$name' ";
if($con->query($Sql_Query) === TRUE){
echo 'Data Inserted Successfully';
}
else{
echo "ppp";
}
mysqli_close($con);
?>Run the application :
