Overview

Purpose

Configure a complete Android development environment for building and running the mobile app on Android emulators and physical devices. This guide covers JDK installation, Android Studio setup, SDK configuration, emulator creation, and environment variables.

When to Use

ALWAYS: Setting up Android development on macOS/Windows/Linux, Android Studio configuration, emulator setup, Gradle issues, SDK configuration SKIP: iOS-only development, web development

Quick Start

1. Install JDK 17: brew install openjdk@17 (macOS) or Adoptium (Windows)
2. Install Android Studio: Download from developer.android.com/studio
3. Configure SDK: Install Android 14 (API 34) via SDK Manager
4. Set Environment Variables: Add ANDROID_HOME and PATH entries
5. Create Emulator: Tools > Device Manager > Create Device
6. Run: task run-android

Phase Summary

Phase 1: Install JDK 17

Android requires JDK 17.

macOS

brew install openjdk@17

# Add to PATH (add to ~/.zshrc or ~/.bashrc)
export JAVA_HOME=$(/usr/libexec/java_home -v 17)
export PATH="$JAVA_HOME/bin:$PATH"

Windows

Download and install from Adoptium (Eclipse Temurin JDK 17).

Linux

sudo apt install openjdk-17-jdk

Verify Installation

java --version
# Should show version 17.x.x

Phase 2: Install Android Studio

Download

Download from developer.android.com/studio

Installation Components

During installation, ensure these components are selected:

• Android SDK
• Android SDK Platform
• Android Virtual Device (AVD)

First Launch

1. Open Android Studio
2. Complete the setup wizard
3. Accept all license agreements

Phase 3: Configure SDK

Open SDK Manager

1. Open Android Studio
2. Go to Settings/Preferences > Languages & Frameworks > Android SDK

SDK Platforms

In SDK Platforms tab, install:

• Android 14 (API 34) - or latest

SDK Tools

In SDK Tools tab, ensure these are installed:

• Android SDK Build-Tools
• Android SDK Command-line Tools
• Android Emulator
• Android SDK Platform-Tools

Phase 4: Set Environment Variables

macOS / Linux

Add to your shell profile (~/.zshrc or ~/.bashrc):

# macOS
export ANDROID_HOME=$HOME/Library/Android/sdk

# Linux
# export ANDROID_HOME=$HOME/Android/Sdk

export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin

Then reload your shell:

source ~/.zshrc  # or ~/.bashrc

Windows

1. Open System Properties > Environment Variables
2. Add new System Variable:
   • Name: ANDROID_HOME
   • Value: C:\Users\<username>\AppData\Local\Android\Sdk
3. Add to Path:
   • %ANDROID_HOME%\emulator
   • %ANDROID_HOME%\platform-tools

Verify

adb --version
# Should output version info

Phase 5: Create Android Emulator

Using Android Studio

1. Open Android Studio
2. Go to Tools > Device Manager (or click phone icon in toolbar)
3. Click Create Device
4. Select a device (e.g., Pixel 7)
5. Select a system image (API 34 recommended)
6. Click Finish

Start Emulator

From Android Studio:

• Click the Play button next to your device in Device Manager

From command line:

# List available emulators
emulator -list-avds

# Start emulator
emulator -avd <avd_name>

Phase 6: Verify Installation

Run All Checks

# Check Java version
java --version

# Check ADB
adb --version

# Check emulator
emulator -list-avds

# Check connected devices
adb devices

Test Android Build

# Ensure environment is set up
task setup-dev

# Start emulator first (from Android Studio or command line)
# Then run
task run-android

Running on Android Emulator

Quick Start

# Ensure environment is set up
task setup-dev

# Start emulator first (from Android Studio or command line)
# Then run
task run-android

Verify Device Connection

adb devices
# Should list your emulator or connected device

Running on Physical Device

Enable Developer Options

1. Go to Settings > About Phone
2. Tap Build Number 7 times
3. Go back to Settings > Developer Options
4. Enable USB Debugging

Connect Device

1. Connect via USB
2. Accept the debugging prompt on your device
3. Verify connection:

   adb devices
   # Should list your device
   

Run

task run-android

Debugging with React Native

Enable Hot Reload

1. Shake device or press Cmd+M (macOS) / Ctrl+M (Windows)
2. Select Enable Fast Refresh

Open Developer Menu

• Emulator: Cmd+M (macOS) or Ctrl+M (Windows)
• Physical device: Shake the device

View Logs

# All React Native logs
adb logcat *:S ReactNative:V ReactNativeJS:V

# Filter for your app (replace with your bundle ID)
adb logcat | grep "{BUNDLE_ID}"

Connect Debugger

1. Open Developer Menu
2. Select Debug with Chrome or Open Debugger
3. Chrome DevTools will open at localhost:8081/debugger-ui

Android Studio Tips

Sync Gradle

If you see Gradle sync issues:

1. Open android/ folder in Android Studio
2. Click Sync Project with Gradle Files (elephant icon)

Invalidate Caches

For strange build issues:

1. File > Invalidate Caches
2. Select Invalidate and Restart

Quick Reference

Common Commands

# Run on Android
task run-android

# Build native project only
task build-android

# Regenerate native project
task generate

# Connect ADB for debugging
task adb-connect

# View logs
adb logcat | grep "ReactNative"

# List devices
adb devices

# List emulators
emulator -list-avds

# Start emulator
emulator -avd <avd_name>

ADB Commands

# List devices
adb devices

# Install APK
adb install app.apk

# Uninstall app (replace with your bundle ID)
adb uninstall {BUNDLE_ID}

# Clear app data (replace with your bundle ID)
adb shell pm clear {BUNDLE_ID}

# Reverse port (for Metro connection)
adb reverse tcp:8081 tcp:8081

# Take screenshot
adb exec-out screencap -p > screenshot.png

# Record screen
adb shell screenrecord /sdcard/recording.mp4

Troubleshooting

Node.js Version Management

For consistent Node.js versions, use Volta (same as iOS setup):

# Install Volta
curl https://get.volta.sh | bash

# Setup Node 20
volta install node@20
volta pin node@20

Verify:

node --version  # Should show v20.x.x
volta --version # Should show version info
