Easily setup an Android development environment on a Mac

android_instructions.md

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

• XCode is installed (via the App Store)
• XCode command line tools are installed (xcode-select --install will prompt up a dialog)
• Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Make sure the doctor is happy (do what it tells you):

brew doctor

Use Homebrew to install Android dev tools:

brew install ant
brew install maven
brew install gradle
brew install android-sdk
brew install android-ndk

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):

android update sdk --no-ui

Install HAXM for blazing fast emulators. Check out the "Configuring VM Acceleration on Mac" section here: http://developer.android.com/tools/devices/emulator.html

Update your environment variables:

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/opt/android-sdk
export ANDROID_NDK_HOME=/usr/local/opt/android-ndk

Update your paths (bonus points to a better solution to the hardcoded build tools version):

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=$ANDROID_HOME/build-tools/19.1.0:$PATH

Periodically run these commands again to ensure you're staying up to date:

brew update
android update sdk --no-ui

• Note: It looks like there might be an issue with brew update and the android-sdk formula.

Install Eclipse, IntelliJ, Android Studio, or your other favorite IDE.

If everything goes smoothly on a moderate network connection you can expect this process to take 2-4 hours.

For anyone with NPE error and a stacktrace related to NDK i had to do this to fix.
Remove export ANDROID_NDK_HOME=/usr/local/opt/android-ndk

Use sdkmanager --update instead android sdk update

@hprobotic I'm trying to run the emulator but I get android sdk not found, has anyone see same problem. I'm using brew cask install android-sdk and my configuration is this

export ANDROID_SDK_ROOT=/usr/local/share/android-sdk
export ANDROID_HOME=/usr/local/share/android-sdk
export ANDROID_NDK_HOME=/usr/local/opt/android-ndk
export PATH="$ANDROID_SDK_ROOT/platform-tools:$ANDROID_SDK_ROOT/tools:$PATH"
sdkmanager "system-images;android-25;google_apis;armeabi-v7a"
sdkmanager --update 
sdkmanager  --list
#avdmanager create avd -n Nexus6P -k "system-images;android-23;google_apis;x86_64" -b google_apis/x86_64 -c 100M -d 7 -f
avdmanager create avd -n test -k "system-images;android-25;google_apis;armeabi-v7a" -b armeabi-v7a -c 100M -d 7 -f
avdmanager list avd
cd $(dirname $(which emulator)) && ./emulator @test -no-audio -no-window -verbose

I get error

emulator: qemu backend: argv[00] = "../emulator/qemu/darwin-x86_64/qemu-system-armel"
emulator: qemu backend: argv[01] = "@test"
emulator: qemu backend: argv[02] = "-no-audio"
emulator: qemu backend: argv[03] = "-no-window"
emulator: qemu backend: argv[04] = "-verbose"
emulator: Concatenated backend parameters:
 ../emulator/qemu/darwin-x86_64/qemu-system-armel @test -no-audio -no-window -verbose
emulator: ERROR: can't find SDK installation directory
emulator: could not find virtual device named 'test'

I get this error

@jpca999 use
brew install caskroom/cask/android-ndk

or just:

brew cask install android-sdk
brew cask install android-ndk

Having the ANT_HOME environment variable set breaks ant.

With it set:
% ant --execdebug
exec "$JAVACMD" -classpath "$LOCALCLASSPATH" -Dant.home="$ANT_HOME" -Dant.library.dir="$ANT_LIB" org.apache.tools.ant.launch.Launcher -cp "$CLASSPATH" "-lib" "/usr/local/share/ant" Error: Could not find or load main class org.apache.tools.ant.launch.Launcher

Without it set:
% ant --execdebug
exec "$JAVACMD" -classpath "$LOCALCLASSPATH" -Dant.home="$ANT_HOME" -Dant.library.dir="$ANT_LIB" org.apache.tools.ant.launch.Launcher -cp "$CLASSPATH"
Buildfile: build.xml does not exist!
Build failed

Update your environment variables

From http://hathaway.cc/post/69201163472/how-to-edit-your-path-environment-variables-on-mac:

https://apple.stackexchange.com/questions/106778/how-do-i-set-environment-variables-on-os-x

android-28 / android-30

sdk can be installed on /Library/Android/sdk or /usr/local/ to be sure check it by

which sdkmanager

Export ANDROID_HOME

export ANDROID_HOME=$HOME/Library/Android/sdk

or

export ANDROID_HOME="/usr/local/share/android-sdk"

Both are valid locations for the android sdk from what I am aware of :)

android-28 / android-30

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

Update:

Use Homebrew to install Android dev tools:

brew cask install android-sdk
brew cask install android-ndk

Update your environment variables:

export ANDROID_NDK_HOME=/usr/local/share/android-ndk
export ANDROID_SDK_ROOT=/usr/local/share/android-sdk

Install all of the Android SDK components:

sdkmanager --update

Thanks @mrded !
Almost one-line offer.

Can you update the instructions save reading all the threads, its the following for me:
brew cask install android-sdk
brew cask install android-ndk

I had so much trouble getting the android sdk and java sdk working with my Pixel, running through multiple iterations of Android Studio setup and different versions of Java. I am on OSX

I finally started over and settled on the following:
java version "1.8.0_171" (JDK 8)

This brew cask was the only thing I could get my Pixel working with:
brew cask install android-studio

react-native-cli: 2.0.1

Thanks to the makers of that cask.

Do you want to avoid struggle with this setup? Read this tutorial

@molcik Just curious, where did you struggle exactly? @mrded's update is pretty straightforward and worked for me ¯_(ツ)_/¯

@molcik that website is just absolute spam. It only provides an alternative "solution" of installing Android Studio. And then links to this very gist.
Should probably be reported as spam...

Of course, brew cask install java will install and help you maintain the JDK.

or asdf plugin-add java && asdf install java oracle-8.191 && asdf global java oracle-8.191

Thank you so much , Finally working with showing this error Cannot find AVD system path. Please define ANDROID_SDK_ROOT

android-ndk is no longer available.

2019 Update:

Some packages have been removed or changed (such as java, android-ndk, etc). This is what worked for me:

brew cask install adoptopenjdk8
brew cask install android-sdk

echo "export ANDROID_HOME=/usr/local/share/android-sdk" >> ~/.bash_profile
source ~/.bash_profile

touch ~/.android/repositories.cfg
sdkmanager --update
sdkmanager "platform-tools" "platforms;android-28"

The sdkmanager had a problem when ~/.android/repositories.cfg didn't exist, but by simply creating the file, it solved the problem.

Install with:
brew cask install android-studio

brew cask install android-studio

brew install android-studio --cask since new brew

For People who make both Android, iOS Apps i made a crazy doc here

Enjoy !

Note, adoptopendk8 has been officially discontinued, it may stop working in recent versions of MacOS.
Temurin is the official successor:

brew install --cask temurin8

I advice you guy to use Jabba instead of anything else ! https://github.com/shyiko/jabba

It's better to use sdkman to instal any jdk version (temurin or any other), ant, gradle and maven
