안드로이드 앱 만들기 #0 (안드로이드 스튜디오 설치 및 환경설정) - 쉽게 앱 만드는 방법 (현직 개발자 설명) , android studio easy tutorial

Android Studio installation and initial setup (tutorial)

Purpose

Step-by-step preparation of an Android development environment (Android Studio + JDK) for building apps.

Target platforms

• Windows (demonstrated in the tutorial)
• macOS (the Android download site auto-detects Mac)
• Linux (mentioned as an option for JDK downloads)

Key steps and commands

1. Download Android Studio

   • Go to the official Android Developer site (Android Studio download page) and click “Download Android Studio”.

2. Verify / install Java Development Kit (JDK)

   • On Windows: press Windows key + R → type cmd → run Command Prompt.
   • Run:
     • java -version
     • If it prints a version, the JDK is installed. If not, install the JDK.
   • To install the JDK, search for Oracle Java (Java SE / JDK) and download the appropriate installer for your OS/architecture (for example, .exe for Windows; packages for macOS/Linux).

3. Run the Android Studio installer

   • Run the Android Studio installer and follow the prompts.
   • The installer offers components such as the Android Virtual Device (AVD) / emulator.
     • Install the emulator if you don’t have a physical Android device.
     • If you already plan to use a real device, the emulator is optional.
   • In the example, the presenter chose not to install the emulator.

4. First run / create a new project

   • Launch Android Studio after installation.
   • Choose a project template (Basic Activity, Empty Activity, etc.).
     • The tutorial recommends using a simple/basic template to get started.
   • Configure project name and settings (the presenter demonstrates entering a project name).

Practical tips and notes

Always verify JDK installation before installing Android Studio to avoid setup issues.

• The emulator (AVD) is useful if you don’t have an Android phone, but it’s optional and can be skipped to reduce installation size.
• The tutorial shows Windows 64-bit specifics; the Android site adapts for macOS users.
• For beginners, pick a simple activity template (e.g., Basic Activity) and switch templates later as needed.
