  • 10GB+ of free disk space
  • Terminal access with sudo privileges
  • Basic knowledge of command line operations

Installing Android Studio

Step 1: Update Your System

First, update your package manager and system packages:

sudo apt update && sudo apt upgrade -y
Enter fullscreen mode Exit fullscreen mode

Step 2: Install Android Studio

We'll use the official PPA repository for the most up-to-date version:

# Add the repository for Android Studio
sudo add-apt-repository ppa:maarten-fonville/android-studio -y

# Update package list
sudo apt update

# Install Android Studio
sudo apt install android-studio -y
Enter fullscreen mode Exit fullscreen mode

Step 3: Verify Installation

Launch Android Studio to verify the installation:

android-studio
Enter fullscreen mode Exit fullscreen mode

Initial Android Studio Configuration

Step 1: Complete the Setup Wizard

  1. Welcome Screen: Click "Next" to start the setup wizard
  2. Install Type: Choose "Standard" for typical development setup
  3. UI Theme: Select your preferred theme (Darcula or Light)
  4. SDK Components: The wizard will automatically download:
    • Android SDK
    • Android SDK Platform
    • Android Virtual Device (AVD)
    • Latest Android SDK build-tools

Step 2: Create a Test Project

To verify everything works correctly:

  1. Create a new Kotlin project
  2. Select "Empty Activity" template
  3. Click "Finish" and wait for Gradle sync
  4. Click the "Run" button (green play icon) to test compilation

React Native/Expo Specific Setup

Critical: Fix the Launch Script

This is essential for React Native/Expo projects to work properly with Android Studio.

Why this matters: The default launch script (studio.sh) doesn't load the Node.js environment properly, causing issues with Gradle configurations that use Node.js commands.

Method 1: Modify Desktop Entry

Edit the desktop application file:

sudo nano /usr/share/applications/android-studio.desktop
Enter fullscreen mode Exit fullscreen mode

Change the Exec line from:

Exec=/opt/android-studio-2025.1.1/android-studio/bin/studio.sh
Enter fullscreen mode Exit fullscreen mode

To:

Exec=/opt/android-studio-2025.1.1/android-studio/bin/studio
Enter fullscreen mode Exit fullscreen mode

Method 2: Launch from Terminal

Alternatively, always launch Android Studio from the terminal:

/opt/android-studio-2025.1.1/android-studio/bin/studio
Enter fullscreen mode Exit fullscreen mode

Note: Update the path according to your Android Studio version.

Understanding the Node.js Integration

React Native projects use Gradle configurations that execute Node.js commands:

def reactNativeAndroidDir = new File(
  providers.exec {
    workingDir(rootDir)
    commandLine("node", "--print", "require.resolve('react-native/package.json')")
  }.standardOutput.asText.get().trim(),
  "../android"
)
Enter fullscreen mode Exit fullscreen mode

Without proper Node.js environment loading, these commands fail, causing build errors.

Environment Variables Configuration

Set Up JAVA_HOME and ANDROID_HOME

Add these environment variables to your ~/.bashrc or ~/.zshrc:

# Open your shell configuration file
nano ~/.bashrc

# Add these lines at the end:

# Set JAVA_HOME to the JDK bundled with Android Studio
export JAVA_HOME="/opt/android-studio-2025.1.1/android-studio/jbr"
export PATH="$JAVA_HOME/bin:$PATH"

# Android SDK paths
export ANDROID_HOME="$HOME/Android/Sdk"
export ANDROID_SDK_ROOT="$ANDROID_HOME"
export PATH="$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$ANDROID_HOME/tools/bin:$PATH"

# React Native development
export PATH="$PATH:$ANDROID_HOME/emulator"
export PATH="$PATH:$ANDROID_HOME/platform-tools"
Enter fullscreen mode Exit fullscreen mode

Apply the Changes 

# Reload your shell configuration
source ~/.bashrc

# Verify the environment variables
echo $JAVA_HOME
echo $ANDROID_HOME
Enter fullscreen mode Exit fullscreen mode

Verify SDK Installation

In Android Studio, go to:

  1. File → Settings (or Android Studio → Preferences on some systems)
  2. Appearance & Behavior → System Settings → Android SDK
  3. Verify that the SDK path matches your ANDROID_HOME variable

Debugging and Development Tools

Android Studio's Built-in Tools

Android Studio provides excellent debugging tools for React Native/Expo development:

1. Logcat Tool Window

The Logcat window displays real-time logs from your device/emulator:

How to access:

  • View → Tool Windows → Logcat
  • Filter logs by app package name
  • Use different log levels (Verbose, Debug, Info, Warn, Error)

2. App Inspection Tool

For advanced debugging of background tasks, network requests, and databases:

How to access:

  • View → Tool Windows → App Inspection
  • Inspect network traffic
  • View database contents
  • Monitor background tasks

3. Device File Explorer

View and modify files on your device/emulator:

Android studio file structure

How to access:

  • View → Tool Windows → Device File Explorer
  • Navigate to /data/data/[your-app-package]/
  • Useful for debugging storage issues

Additional Development Tools

  1. ADB (Android Debug Bridge): 
   # List connected devices
   adb devices

   # Install APK
   adb install path/to/your/app.apk

   # View device logs
   adb logcat
Enter fullscreen mode Exit fullscreen mode
  1. Emulator Management:
    • Tools → AVD Manager
    • Create multiple device configurations
    • Test different Android versions

Common Issues and Solutions

Issue 1: "Autolinking is not set up in settings.gradle"

This error occurs when Expo modules aren't properly configured in your Android project.

Solution:

  1. First, try reopening Android Studio and reloading the project
  2. Clean and reinstall dependencies: 
   rm -rf node_modules
   npm install
   # or
   yarn install
Enter fullscreen mode Exit fullscreen mode
  1. Verify your android/settings.gradle file: 
pluginManagement {
  def reactNativeGradlePlugin = new File(
    providers.exec {
      workingDir(rootDir)
      commandLine("node", "--print", "require.resolve('@react-native/gradle-plugin/package.json', { paths: [require.resolve('react-native/package.json')] })")
    }.standardOutput.asText.get().trim()
  ).getParentFile().absolutePath
  includeBuild(reactNativeGradlePlugin)

  def expoPluginsPath = new File(
    providers.exec {
      workingDir(rootDir)
      commandLine("node", "--print", "require.resolve('expo-modules-autolinking/package.json', { paths: [require.resolve('expo/package.json')] })")
    }.standardOutput.asText.get().trim(),
    "../android/expo-gradle-plugin"
  ).absolutePath
  includeBuild(expoPluginsPath)
}

plugins {
  id("com.facebook.react.settings")
  id("expo-autolinking-settings")
}

extensions.configure(com.facebook.react.ReactSettingsExtension) { ex ->
  if (System.getenv('EXPO_USE_COMMUNITY_AUTOLINKING') == '1') {
    ex.autolinkLibrariesFromCommand()
  } else {
    ex.autolinkLibrariesFromCommand(expoAutolinking.rnConfigCommand)
  }
}
expoAutolinking.useExpoModules()

rootProject.name = 'your-app-name'

expoAutolinking.useExpoVersionCatalog()

include ':app'
includeBuild(expoAutolinking.reactNativeGradlePlugin)
Enter fullscreen mode Exit fullscreen mode
  1. If the issue persists, regenerate native code: 
   npx expo prebuild --clean
Enter fullscreen mode Exit fullscreen mode

Issue 2: Gradle Sync Failures

Common causes and solutions:

  1. Node.js not found: Ensure you're using the correct Android Studio launcher (not studio.sh)
  2. JDK version mismatch: Use the bundled JDK in Android Studio
  3. Network issues: Configure proxy settings if behind a corporate firewall

Issue 3: Emulator Performance Issues

Optimization tips:

  1. Enable Hardware Acceleration: 
   # Check if KVM is available
   grep -E "(vmx|svm)" /proc/cpuinfo

   # Install KVM if not present
   sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
Enter fullscreen mode Exit fullscreen mode
  1. AVD Configuration:
    • Allocate sufficient RAM (2GB minimum)
    • Enable "Use Host GPU" in AVD settings
    • Use x86_64 images for better performance

Best Practices

1. Project Structure

  • Never directly edit the android/ folder in Expo projects
  • Use Expo Config Plugins for native modifications
  • Keep custom native modules in separate directories

2. Autolinking Configuration

Only modify autolinking settings if you have specific requirements:

{
  "expo": {
    "name": "your-app-name",
    "autolinking": {
      "searchPaths": ["../../packages"],
      "nativeModulesDir": "../../packages"
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

3. Development Workflow

  1. Use Expo CLI for project creation and management
  2. Test on real devices when possible
  3. Use Android Studio for:
    • Native code debugging
    • Performance profiling
    • Advanced logging
    • Build analysis

4. Version Management

  • Keep Android Studio updated
  • Use specific Android SDK versions for consistency
  • Document your environment setup in project README
