Android SDK (Software Development Kit): A collection of tools and libraries essential for developing Android apps.
Android Studio: An integrated development environment (IDE) specifically designed for Android development.
Java/Kotlin: The official programming languages of Android.
XML (Extensible Markup Language): For defining user interfaces.

Getting Started with Android Studio

To delve into Android programming, you'll need to set up Android Studio. Begin by downloading and installing the latest version from the official Android website.

Once installed, create a new Android project within Android Studio. Android Studio will generate a basic application structure, including code files and XML layouts. You can modify these files to customize your app.

Understanding Android App Architecture

Android apps are typically structured into four main components:

Activities: Represent individual screens or pages within your app.
Fragments: Modular UI components that can be reused across multiple activities.
Services: Background tasks that run independently of activities.
Content Providers: Manage and share data between different apps.

Creating Your First Android App

Let's create a simple "Hello World!" app to demonstrate the basics of Android programming.

Step 1: Create a New Activity

Right-click on the "app" folder in Android Studio and select "New" > "Activity." Name it "MainActivity."

Step 2: Design the User Interface

In the "activity_main.xml" file, replace the default layout with the following code:

xml

Step 3: Implement the Activity Class

In the "MainActivity.java" file, add the following code:

java public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); }}

Step 4: Run the App

Click the green "Run" button in Android Studio to build and run your app on an emulator or connected device.
