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:

• XCode command line tools are installed (xcode-select --install will prompt up a dialog)

1. Install Homebrew:

   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

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

   brew doctor
   brew tap caskroom/cask
   brew update

3. Install Java 8:

   • Fetch it and unzip.

   • cd zulu8.46.0.19-ca-fx-jdk8.0.252-macosx_x64/

   • sudo mkdir -p /Library/Java/JavaVirtualMachines/ && sudo cp -aR zulu-8.jdk /Library/Java/JavaVirtualMachines/

4. Install Python 3:

   brew install python3

5. Use Homebrew to install Android dev tools:

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

6. Install Flutter:

   brew tap flschweiger/flutter
   brew cask install flutter

7. Install HAXM for blazing fast emulators:

   brew cask install intel-haxm

8. Update your environment variables (add the following to your ~/.bash_profile):

   export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
   export ANT_HOME=/usr/local/opt/ant/libexec
   export MAVEN_HOME=/usr/local/opt/maven
   export GRADLE_HOME=/usr/local/opt/gradle
   export ANDROID_HOME=/usr/local/share/android-sdk
   export ANDROID_NDK_HOME=/usr/local/share/android-ndk
   export INTEL_HAXM_HOME=/usr/local/Caskroom/intel-haxm
   
   alias emulator=$ANDROID_HOME/emulator/emulator
   
   export PATH=$ANT_HOME/bin:$PATH
   export PATH=$MAVEN_HOME/bin:$PATH
   export PATH=$GRADLE_HOME/bin:$PATH
   export PATH=$ANDROID_HOME/emulator:$PATH
   export PATH=$ANDROID_HOME/tools:$PATH
   export PATH=$ANDROID_HOME/tools/bin:$PATH
   export PATH=$ANDROID_HOME/platform-tools:$PATH
   export PATH=$ANDROID_HOME/build-tools/$(ls $ANDROID_HOME/build-tools | sort | tail -1):$PATH
   export PATH=$PATH:/usr/local/Caskroom/flutter/latest/flutter/.pub-cache/bin:/usr/local/Caskroom/flutter/latest/flutter/bin/cache/dart-sdk/bin

9. Restart terminal

10. 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):

    sdkmanager "platform-tools" "cmdline-tools" "platforms;android-29" "build-tools;29.0.3"
    sdkmanager "extras;android;m2repository" "extras;google;m2repository"
    sdkmanager "emulator" "patcher;v4" "tools"
    sdkmanager "system-images;android-29;google_apis_playstore;x86_64"

11. Create AVD:

    avdmanager create avd -n PixelXL -k "system-images;android-29;google_apis_playstore;x86_64" -d 19

12. Upgrade Flutter:

    flutter channel beta
    flutter upgrade

13. Run flutter doctor (do what it tells you)
