Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.
Here the SDK is under /usr/local/share/android-sdk because I may switch to a different Catalina user in the future, but it works fine under /Users/<your_user>/Library/Android/sdk as well.
See for brew, python3 and NodeJS on nvm see gist https://gist.github.com/agrcrobles/3d945b165871c355b6f169c317958e3e
Open JDK 14 works fine with gradle 6.x
To install the JDKs 8 ( LTS ) from AdoptOpenJDK:
# brew tap adoptopenjdk/openjdk
brew cask install adoptopenjdk/openjdk/adoptopenjdk8
Do not follow this step if installed adoptopenjdk8
brew cask install java8
Export JAVA_HOME on your bash profile or zshrc
export JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home
Or try Command line tools | Android
Use Command line tools or SDK Manager
Quick reminder: Have as many build tools as you want, have one platform tool with backwards compatibility :=)
Download and Install Command line tools for mac ( not the android studio unless I need it )
https://developer.android.com/studio#cmdline-tools
https://developer.android.com/studio/command-line
https://developer.android.com/studio/command-line/sdkmanager
Use Homebrew to install Android dev tools: Note that Java8 is tricky since licence changed: https://stackoverflow.com/questions/24342886/how-to-install-java-8-on-mac
brew install gradle
brew cask install android-sdk
Optional
brew install ant
brew install maven
brew cask install android-ndk
https://developer.android.com/studio#cmdline-tools
Install all of the Android SDK components (you will be prompted to agree to license info and then this will take a while to run):
If you need to have openjdk first in your PATH run: echo 'export PATH="/usr/local/opt/openjdk/bin:$PATH"' >> ~/.zshrc
For compilers to find openjdk you may need to set: export CPPFLAGS="-I/usr/local/opt/openjdk/include"
touch ~/.android/repositories.cfg
yes | sdkmanager --licenses
sdkmanager "platform-tools" "platforms;android-28"
sdkmanager --no_https --install 'build-tools;28'
sdkmanager --no_https --install emulator
sdkmanager --list
touch ~/.android/repositories.cfg
yes | sdkmanager --licenses
sdkmanager --update
sdkmanager --no_https --install emulator
sdkmanager --no_https --install platform-tools
sdkmanager --no_https --install 'system-images;android-29;google_apis_playstore;x86_64'
sdkmanager --no_https --install 'extras;intel;Hardware_Accelerated_Execution_Manager'
sdkmanager --no_https --install 'build-tools;29.0.2'
sdkmanager --no_https --install 'platforms;android-29'
sdkmanager --list
touch ~/.android/repositories.cfg
sdkmanager "platform-tools" "platforms;android-23"
sdkmanager "build-tools;23.0.1"
Install HAXM for blazing fast emulators. Check out the "Configuring VM Acceleration on Mac" section here: http://developer.android.com/tools/devices/emulator.html
brew cask install intel-haxm // this might not work on high sierra.
Edit: You can download the dmg and install manually from Intel's site
Install emulators? Nga copied from https://gist.github.com/gasolin/9300f5f9276b2df884c80da3e2c54ffc
sdkmanager --no_https --install emulator
sdkmanager --no_https --install platform-tools
sdkmanager --no_https --install 'system-images;android-29;google_apis_playstore;x86_64'
sdkmanager --no_https --install 'extras;intel;Hardware_Accelerated_Execution_Manager'
sdkmanager --update
sdkmanager --list
Create and run virtual devices? Nga copied from https://gist.github.com/gasolin/9300f5f9276b2df884c80da3e2c54ffc
avdmanager list (find device skin id, lets use pixel 17)
avdmanager create avd -f -n test -d 17 -k 'system-images;android-29;google_apis_playstore;x86_64'
avdmanager list avd (or emulator -list-avds)
/usr/local/share/android-sdk/emulator/emulator -avd test
sdk can be installed on /Library/Android/sdk or /usr/local/ to be sure check it by
which sdkmanager
export ANDROID_HOME=$HOME/Library/Android/sdk
or
export ANDROID_HOME="/usr/local/share/android-sdk"
Both locations are valid ones from what I am aware of :)
export ANT_HOME=/usr/local/opt/ant
export MAVEN_HOME=/usr/local/opt/maven
export GRADLE_HOME=/usr/local/opt/gradle
export ANDROID_HOME=/usr/local/share/android-sdk
export ANDROID_SDK_ROOT=/usr/local/share/android-sdk
export ANDROID_NDK_HOME=/usr/local/share/android-ndk
export INTEL_HAXM_HOME=/usr/local/Caskroom/intel-haxm
Update your paths (bonus points to a better solution to the hardcoded build tools version):
To Copy paste, It's a good idea double check your paths anyways.
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$ANT_HOME/bin:$PATH
export PATH=$MAVEN_HOME/bin:$PATH
export PATH=$GRADLE_HOME/bin:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/build-tools/23.0.1:$PATH
export PATH=$ANDROID_HOME/build-tools/28.0.3:$PATH
Suggested: You will have to add the ANDROID_HOME to the profile configuration settings either on .zshrc, .bashrc or .bash_profile
If emulator doesn't run, i am here to remind you to provide access into System Preferences - Security & Privacy
Optional, install android studio or intellij ide, point your sdk, java_home, build and platform tools to the already installed ones.
