How to Create and Run Android Project using Android Studio - Amharic (2019)

Introduction

This tutorial will guide you through the process of creating and running an Android project using Android Studio. Whether you are a complete beginner or looking to refresh your skills, this step-by-step guide will help you set up your development environment and get your first project running on a mobile device.

Step 1: Install Android Studio

• Download Android Studio from the official website.
• Follow the installation instructions for your operating system (Windows, macOS, or Linux).
• Ensure that you install the Android SDK as part of the setup process.

Step 2: Create a New Android Project

• Open Android Studio.
• Click on "Start a new Android Studio project."
• Choose the project template. For beginners, select "Empty Activity."
• Fill in the project details:
  • Name: Enter your project name.
  • Package name: Use a unique identifier (e.g., com.example.myapp).
  • Save location: Choose a directory for your project.
  • Language: Select Java or Kotlin based on your preference.
  • Minimum API level: Choose the lowest version of Android you want to support.
• Click “Finish” to create the project.

Step 3: Understand the Project Structure

• Familiarize yourself with the project files:
  • app/src/main/java: Contains your Java/Kotlin files.
  • app/src/main/res: Contains resources like layouts and images.
  • app/build.gradle: Defines project dependencies and settings.

Step 4: Design the User Interface

• Open the activity_main.xml file located in app/src/main/res/layout.
• Use the layout editor to drag and drop UI components like buttons, text views, and images.
• Modify properties of the components in the attributes panel.

Step 5: Write the Code

• Open the MainActivity.java or MainActivity.kt file in app/src/main/java.
• Implement functionality for your UI components. For example, to respond to a button click:

  Button myButton = findViewById(R.id.my_button);
  myButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          // Action to perform on button click
      }
  });
  

Step 6: Run Your Application

• Connect your Android device to your computer via USB or use an emulator.
• Ensure USB debugging is enabled on your Android device.
• Click on the green "Run" button in Android Studio.
• Select your device or emulator from the list and click "OK."
• Wait for the build to complete; your app should launch on the selected device.

Step 7: Debugging and Troubleshooting

• If you encounter errors, check the "Logcat" window in Android Studio for logs.
• Common issues may arise from missing permissions or incorrect package names.
• Ensure that your device is set up correctly and that you have the necessary SDK components installed.
