It covers Android SDK, Java (JDK), Flutter, Path wiring, Plugin setup, Validation, AVD/emulator, and creating a project—plus quick fixes.

Assumptions: default shell = zsh, Apple Silicon path (/opt/homebrew). If you’re on Intel, replace /opt/homebrew with /usr/local.

---

1) Install Java (JDK)

Most Android/Gradle stacks are happy with JDK 17+.

# Install (latest LTS). If you specifically want 17, use: brew install --cask temurin17
brew install --cask temurin

# Ensure JAVA_HOME is set automatically
echo 'export JAVA_HOME="$(/usr/libexec/java_home)"' >> ~/.zshrc
source ~/.zshrc

# Verify
java -version
Code language: PHP (php)

---

2) Install the Android SDK (CLI-only path, no GUI required)

If you prefer Android Studio GUI, install it via brew install --cask android-studio and use Preferences → Android SDK to install Command-line Tools, Platform-Tools, Build-Tools. Then skip to step 3.

2.1 Create SDK home and install command-line tools

# Set SDK root (mac default location)
echo 'export ANDROID_SDK_ROOT="$HOME/Library/Android/sdk"' >> ~/.zshrc
echo 'export ANDROID_HOME="$ANDROID_SDK_ROOT"' >> ~/.zshrc
source ~/.zshrc

# Create the folder
mkdir -p "$ANDROID_SDK_ROOT"

# Install Android command-line tools
brew install --cask android-commandlinetools
Code language: PHP (php)

2.2 Put tools where Flutter expects them

Flutter looks for sdkmanager at:
$ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager

mkdir -p "$ANDROID_SDK_ROOT/cmdline-tools"

# Try the "latest" symlink first (preferred; auto-updates with brew)
rm -rf "$ANDROID_SDK_ROOT/cmdline-tools/latest"
ln -s "/opt/homebrew/Caskroom/android-commandlinetools/latest/cmdline-tools" \
      "$ANDROID_SDK_ROOT/cmdline-tools/latest" 2>/dev/null || true

# If your Caskroom doesn't have "latest", symlink the version you saw (example: 13114758)
if [ ! -x "$ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager" ]; then
  ln -s "/opt/homebrew/Caskroom/android-commandlinetools/13114758/cmdline-tools" \
        "$ANDROID_SDK_ROOT/cmdline-tools/latest"
fi
Code language: PHP (php)

2.3 Add Android tools to PATH

# Add PATHs (platform-tools, emulator, cmdline-tools)
{
  echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/platform-tools"'
  echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/emulator"'
  echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin"'
} >> ~/.zshrc
source ~/.zshrc

# Sanity checks
which sdkmanager
which adb
Code language: PHP (php)

2.4 Install core SDK components

# Avoid "repositories.cfg could not be loaded" warning
mkdir -p ~/.android && touch ~/.android/repositories.cfg

# Accept licenses (press y for each)
sdkmanager --licenses

# Core packages
sdkmanager "platform-tools" "emulator" "cmdline-tools;latest"

# Choose a modern Android platform + build-tools (adjust if needed)
sdkmanager "platforms;android-35" "build-tools;35.0.0"

# Optional: system image for an ARM64 emulator
sdkmanager "system-images;android-35;google_apis;arm64-v8a"
Code language: PHP (php)

---

3) Install Flutter (CLI)

brew install --cask flutter

# Put Flutter on PATH using the SDK’s own path (future-proof)
echo 'export PATH="$PATH:$(flutter sdk-path)/bin"' >> ~/.zshrc
source ~/.zshrc

# Verify
flutter --version
Code language: PHP (php)

---

4) Wire Flutter ↔ Android SDK & Validate

# (Only needed if Flutter doesn’t auto-detect your SDK)
flutter config --android-sdk "$ANDROID_SDK_ROOT"

# Accept Android licenses via Flutter
flutter doctor --android-licenses

# Full diagnostic
flutter doctor -v
Code language: PHP (php)

You should see green checks for:

• Flutter
• Android toolchain
• Xcode (if installed)
• IDEs (if detected)

---

5) Install Flutter plugins (IDEs)

Android Studio

1. Preferences → Plugins → Marketplace
2. Install Flutter (it auto-installs Dart)
3. Restart Android Studio
4. Preferences → Languages & Frameworks → Flutter → set Flutter SDK path (yours was: /opt/homebrew/share/flutter or use flutter sdk-path)

VS Code (optional)

• Install Flutter and Dart extensions from the Marketplace.

---

6) Locate SDK paths quickly (for future prompts)

# Flutter SDK root
flutter sdk-path

# Android SDK root
echo $ANDROID_SDK_ROOT

# Where is sdkmanager/adb?
which sdkmanager
which adb
Code language: PHP (php)

---

7) Create and run a Flutter project

# Create
flutter create hello_app
cd hello_app

# List devices (emulators/phones)
flutter devices
Code language: PHP (php)

• If you already created an AVD, start it: emulator -list-avds emulator -avd Pixel_8_API_35
• Then run: flutter run

---

8) Create an Android emulator (AVD) from CLI (optional)

# Create a Pixel 8 AVD targeting android-35
avdmanager create avd -n Pixel_8_API_35 \
  -k "system-images;android-35;google_apis;arm64-v8a" -d pixel_8

# Start it
emulator -avd Pixel_8_API_35
Code language: PHP (php)

---

9) (Optional) iOS setup on macOS

If you want to run on iPhone simulators:

# Xcode CLTs
xcode-select --install || true

# First-run (may prompt)
sudo xcodebuild -runFirstLaunch

# (Sometimes license acceptance is interactive in GUI)
# Install CocoaPods for iOS deps
brew install cocoapods
pod setup

# Check again
flutter doctor -v
Code language: PHP (php)

---

10) Quick Troubleshooting (copy/paste fixes)

A. Android sdkmanager not found

# Ensure the file exists here:
ls "$ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager"

# Ensure PATH contains it
echo $PATH | tr ':' '\n' | grep cmdline-tools || \
echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin"' >> ~/.zshrc && source ~/.zshrc

# Reinstall / relink cmdline tools if missing
brew reinstall --cask android-commandlinetools
rm -rf "$ANDROID_SDK_ROOT/cmdline-tools/latest"
ln -s "/opt/homebrew/Caskroom/android-commandlinetools/latest/cmdline-tools" \
      "$ANDROID_SDK_ROOT/cmdline-tools/latest"
Code language: PHP (php)

B. cmdline-tools component is missing

sdkmanager "cmdline-tools;latest"
Code language: JavaScript (javascript)

C. Emulator not listed in flutter devices

emulator -list-avds
# If none, create one (see section 8), then:
emulator -avd Pixel_8_API_35
flutter devices
Code language: PHP (php)

D. License prompts keep appearing

yes | sdkmanager --licenses
flutter doctor --android-licenses

E. Wrong SDK path in Android Studio

• Set Preferences → Languages & Frameworks → Flutter → Flutter SDK path to:
  • flutter sdk-path (paste the result), e.g. /opt/homebrew/share/flutter

F. Verify everything at once

echo "ANDROID_SDK_ROOT=$ANDROID_SDK_ROOT"
which sdkmanager && sdkmanager --list | head -n 30
adb version
java -version
which flutter && flutter --version
flutter doctor -v
Code language: PHP (php)

---

11) One-time setup script (save as setup_flutter_android_macos.sh)

Edit the versioned line (13114758) if your cask uses a different folder; the script also tries the latest alias.

#!/usr/bin/env bash
set -euo pipefail

# JDK
brew install --cask temurin || true

# SDK roots
grep -q 'ANDROID_SDK_ROOT=' ~/.zshrc || echo 'export ANDROID_SDK_ROOT="$HOME/Library/Android/sdk"' >> ~/.zshrc
grep -q 'ANDROID_HOME=' ~/.zshrc || echo 'export ANDROID_HOME="$ANDROID_SDK_ROOT"' >> ~/.zshrc
source ~/.zshrc

mkdir -p "$ANDROID_SDK_ROOT"

# Android command-line tools
brew install --cask android-commandlinetools || true
mkdir -p "$ANDROID_SDK_ROOT/cmdline-tools"
rm -rf "$ANDROID_SDK_ROOT/cmdline-tools/latest"
ln -s "/opt/homebrew/Caskroom/android-commandlinetools/latest/cmdline-tools" "$ANDROID_SDK_ROOT/cmdline-tools/latest" \
  || ln -s "/opt/homebrew/Caskroom/android-commandlinetools/13114758/cmdline-tools" "$ANDROID_SDK_ROOT/cmdline-tools/latest"

# PATHs
grep -q 'platform-tools' ~/.zshrc || echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/platform-tools"' >> ~/.zshrc
grep -q 'emulator' ~/.zshrc || echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/emulator"' >> ~/.zshrc
grep -q 'cmdline-tools/latest/bin' ~/.zshrc || echo 'export PATH="$PATH:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin"' >> ~/.zshrc
source ~/.zshrc

# Accept licenses & core packages
mkdir -p ~/.android && touch ~/.android/repositories.cfg
yes | sdkmanager --licenses || true
sdkmanager "platform-tools" "emulator" "cmdline-tools;latest" \
           "platforms;android-35" "build-tools;35.0.0" || true

# Flutter
brew install --cask flutter || true
grep -q 'flutter sdk-path' ~/.zshrc || echo 'export PATH="$PATH:$(flutter sdk-path)/bin"' >> ~/.zshrc
source ~/.zshrc

# Final check
flutter doctor -v
echo "Done. If Android Studio is installed, add the Flutter plugin and set Flutter SDK path to: $(flutter sdk-path)"
Code language: PHP (php)

Run it:

chmod +x setup_flutter_android_macos.sh
./setup_flutter_android_macos.sh

---

12) Short checklist (what “green” looks like)

• java -version → prints Temurin/Oracle/OpenJDK
• which sdkmanager → points to $ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager
• adb version → prints version
• flutter --version → prints 3.35.x
• flutter doctor -v → Android toolchain ✅
• Android Studio → Plugins: Flutter + Dart, Flutter SDK path set
• flutter create app && cd app && flutter run → launches on emulator/device

---

That’s it. Save this guide and the script; next time it’s a one-shot setup with predictable results.
