Android + React Native + Fastlane: Working with multiple build types

This is the companion repository for my medium post.

Check out the React Native DevOps Guide!!!

The DevOps Guide includes concept discussion and step by step walkthroughs for setting up your own Jenkins agent and running iOS and Android builds, plus a whole lot more.

Gradle Configurations

Global gradle.properties - defining node executable

# This file lives in ~/.gradle/gradle.properties

MYAPP_RELEASE_STORE_FILE=foo.keystore
MYAPP_RELEASE_KEY_ALIAS=foo-alias
MYAPP_RELEASE_STORE_PASSWORD=foo_store_release
MYAPP_RELEASE_KEY_PASSWORD=foo_key_release

org.gradle.daemon=true

NODE_PATH=[YOUR_HOME_PATH]/.nvm/versions/node/v[YOUR_NODE_VERSION]/bin/node

React ExtraPropertiesExtension

project.ext.react = [
    entryFile: "index.js",
    nodeExecutableAndArgs: hasProperty('NODE_PATH')?[NODE_PATH]:["node"],
    bundleInDebug: false,

new buildType, applicationIdSuffix, signingConfigs

      proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"

  }

Fastlane Actions

Yarn install

yarn(
  command: "install",
  package_path: "./package.json"
)

Android versioning

ANDROID_VERSION_NAME = get_version_name(
  gradle_file_path:"android/app/build.gradle",
  ext_constant_name:"versionName"
)
ANDROID_VERSION_CODE = get_version_code(
  gradle_file_path:"android/app/build.gradle",
  ext_constant_name:"versionCode"
)

Adding badges

if options[:badge]
    add_badge(
      shield: "#{ANDROID_VERSION_NAME}-#{ANDROID_VERSION_CODE}-orange",
      glob: "/android/app/src/main/res/mipmap-*/ic_launcher.png",
      alpha: true,
      shield_scale: "0.75"
    )
  end

Upload to Crashlytics

if ENV["CRASHLYTICS_API_KEY"] && ENV["CRASHLYTICS_BUILD_SECRET"]
  crashlytics(
    api_token: ENV["CRASHLYTICS_API_KEY"],
    build_secret: ENV["CRASHLYTICS_BUILD_SECRET"],
    groups: ["your-test-groups-here"],
    notes: "#{ANDROID_VERSION_NAME}-#{ANDROID_VERSION_CODE} beta release - fastlane generated",
    notifications: true
  )
end

Upload to Play Store

if options[:play_store]
  # upload to alpha track on google play developer's console
  supply(track: "alpha", apk: "android/app/build/outputs/apk/app-release.apk")
end
