    Android Development without Android Studio

Note, most of my Android development is React Native based, so YMMV.
Prerequisites


Homebrew
Xcode (installed from App store)
Xcode command line tools (xcode-select --install)

Instructions

Install packages

brew install gradle
brew cask install adoptopenjdk8 adoptopenjdk8-jre intel-haxm android-sdk android-ndk

Set environment variables (in .zshrc, etc.)

export ANDROID_SDK_ROOT="/usr/local/share/android-sdk"
export ANDROID_NDK_ROOT="/usr/local/share/android-ndk"
export PATH=$ANDROID_SDK_ROOT/emulator:$PATH:$ANDROID_SDK_ROOT/platform-tools:$ANDROID_SDK_ROOT/build-tools/28.0.3

Download packages

# add this empty file (macOS will complain that it doesnt exist)
touch ~/.android/repositories.cfg

# accept the sdkmanager licenses
yes | sdkmanager --licenses

# run updates
sdkmanager --update

# install packages
sdkmanager --install emulator
sdkmanager --install platform-tools
sdkmanager --install 'system-images;android-29;google_apis_playstore;x86_64'
sdkmanager --install 'build-tools;29.0.2' # pick your version, this is what's used in react native >=0.60
sdkmanager --install 'platforms;android-29'

Working with emulators

# show all potential emulators
avdmanager list

# create an emulator
avdmanager create avd -f -n EMU_NAME -d ID_NUMBER -k 'system-images;android-29;google_apis_playstore;x86_64'

# view all created avds
avdmanager list avd

# run an emulator
emulator @EMU_NAME

# delete an avd
avdmanager delete avd -n EMU_NAME

Protip: enable physical keyboard on all emulators: for f in ~/.android/avd/*.avd/config.ini; do echo 'hw.keyboard=yes' >> "$f"; done
