This sample Android project is used to practice Github Actions CI/CD

• Create a Gemfile in the root directory of your Android project
• Then just run the following command: sudo gem install fastlane -NV
• Setup Fastlane using this command: fastlane init and follow the prompts to fill in the details about your app: package name, Path to the json secret file, Download existing metadata and setup metadata management (y) -> it will create Appfile and Fastfile in fastlane folder
• Type fastlane test to check the setup -> it will print out fastlane.tools finished successfully if the setup successful done
• Add the firebase plugin fastlane add_plugin firebase_app_distribution
• Type command in root folder of project to see all actions of plugin firebase_app_distribution bundle exec fastlane action firebase_app_distribution
• Getting the Firebase App ID: go to firebase console -> add project -> add app -> copy App ID in project settings
• Go to Google cloud platform -> select project created from firebase -> create a new service account -> add role 'Firebase Admin' 'Firebase App Distribution Admin' 'Cloud Storage - Storage Object Creator' 'Cloud Storage for Firebase Admin' , then create key json file download and add into project name firebase_credentials.json or copy json into github secrets
• To run fastlane local it need to run this export FIREBASE_APP_ID=YOUR_APP_ID
• Configure Firebase App Distribution: Create a new directory FirebaseAppDistributionConfig under the root directory of your project. Create a new file groups.txt in the created directory. Create a new file release_notes.txt in the same directory.
• create distribute lane (in Fastfile)
• Run local by command fastlane distribute
• Use firebase cli token instead of firebase_credentials.json
  • Install firebase tool npm install -g firebase-tools
  • Type command firebase login:ci it will print firebase cli token
  • Type this command to test firebase cli token firebase projects:list --token FIREBASE_CLI_TOKEN -> list all projects in firebase account
• Add bundletool plugin fastlane add_plugin bundletool this tool will extract an universal apk from .aab file to distribute it to firebase, app center, store, ...

• convert firebase credentials file to base64 string use command base64 -i firebase_credentials.json > firebase_credentials.json.b64
• add into github secrets: FIREBASE_CREDENTIALS, FIREBASE_APP_ID
• create workflow distribute.yml
• Push code to main branch to see how github actions distribute workflow run and distribute apk to firebase app distribution

keytool -genkey -v -keystore YOUR_FILE_NAME.keystore -alias YOUR_ALIAS_NAME -storepass YOUR_ALIAS_PWD -keypass YOUR_ALIAS_PWD -keyalg RSA -validity 36500

base64 -i firebase_credentials.json > firebase_credentials.json.b64

• install firebase cli npm install -g firebase-tools firebase login:ci firebase logout -- token $token (call this to clear token)
• check token firebase projects:list --token "$FIREBASE_TOKEN"

• $ openssl base64 -A -in demo_alpha.keystore -out demo_alpha.txt
• copy text in demo_alpha.txt to github actions secrets
