Create Your First Android App in Android Studio

In this first Android Tutorial, we are going to create a new android studio app while learning Android App developments in Android Studio. Let’s make an android app that shows the toast when Button Click on in Android App.

How to create an Android App using Android Studio?

First, you need to set up the basic requirements which are required to develop an android application

Install Android Studio IDE

Android Studio is the official software of Google or IDE (Integrated Development Environment) to develop an Android app. Android Studio provides the right environment for Android app development and coding. There are currently two languages for the development of native Android applications

  • Java
  • Kotlin

However, most of the applications available in the Play Store are only developed in Java, since Kotlin is the latest language introduced by Google for Android development.

Before jumping to the Android Studio download, meet the requirements first.

Operating system requirements:


  • The Java Development Kit (JDK)

If you have the latest JDK installed on your system, you do not require to install it again. The Java Development Kit(JDK) consists of tools like the Java compiler, used by the Software development kit (SDK), and an integrated development environment (IDE) to develop Java programs. The JDK also includes a Java Runtime Environment (JRE) that allows Java programs, such as Eclipse, to run on the system.

<?xml version="1.0" encoding="utf-8"?>
 <androidx.constraintlayout.widget.ConstraintLayout xmlns:android=""
         android:text="My First Android Application"
         app:layout_constraintVertical_bias="0.161" />
         android:text="Click Me"
         app:layout_constraintVertical_bias="0.373" />

Bind Interface to Java

To start the java coding, you need the file that is created automatically. Therefore, you must first bind the Button to a Java file.

public class MainActivity extends AppCompatActivity { 

 protected void onCreate(Bundle savedInstanceState) {

     //initialize the button
     Button btnClickMe = findViewById(;

     //set onclick listener
     btnClickMe.setOnClickListener(new View.OnClickListener() {
         public void onClick(View view) {
             //set display toast message
             Toast.makeText(MainActivity.this, "Button Clicked", Toast.LENGTH_SHORT).show();

Android App Handle Click Listener Method

Display the toast message with the button click function. We need to create a simple onClick (), listener.

//set onclick listener
 btnClickMe.setOnClickListener(new View.OnClickListener() {
     public void onClick(View view) {
         //set display toast message
         Toast.makeText(MainActivity.this, "Button Clicked", Toast.LENGTH_SHORT).show();

Run Your Android App

Click the run button to run your application on the emulator or your android device. When application launch in the device, clicks the button. you can see the toast message when you click the button.

Happy Coding…!
