Setting Up Android Studio

Android Studio is the official Integrated Development Environment (IDE) for Android app development. It provides tools for coding, testing, and debugging Android applications. This lesson will guide you through the process of setting up Android Studio.

Before installing Android Studio, ensure you have the following:

• Operating System: Windows, macOS, or Linux.
• Java Development Kit (JDK) 8 or higher installed on your system.
• At least 4 GB of RAM (8 GB recommended).
• Minimum of 2 GB of available disk space.

1. Download Android Studio: Visit the official Android Studio website and download the installer for your OS.
2. Run the Installer: Follow the on-screen instructions to install Android Studio. Make sure to install the Android SDK and the Android Virtual Device (AVD) during the setup.
3. Launch Android Studio: Once installation is complete, open Android Studio.

After launching Android Studio, you need to configure it:

1. SDK Manager: Navigate to File > Settings > Appearance & Behavior > System Settings > Android SDK. Ensure the latest SDK is installed and select the necessary SDK platforms.
2. AVD Manager: Set up the Android Virtual Device by going to Tools > AVD Manager. Click on Create Virtual Device and follow the prompts.

Now that Android Studio is set up, let’s create a simple project:

1. Open Android Studio and select New Project.
2. Choose a Template (e.g., Empty Activity) and click Next.
3. Enter your Application Name, Package Name, and Save Location. Click Finish.
4. Once the project loads, open app > src > main > res > layout > activity_main.xml and add the following XML code:

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent">
   
       <TextView
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Hello, Android!" />
   
   </RelativeLayout>

5. Run the application by clicking the green play button. Select your AVD and click OK.
