How to Enable Fastlane for App Deployment

Android​

Enable API access​

Create a Service Account​

  • Go to the Google Cloud Console
  • Click + Create Service Account at the top
  • Leave the display name blank
  • Set ID to "project-name-fastlane"
  • Set Description to "Service account for fastlane deployment"
  • Click Create and Continue
  • Click Continue (no role needed)
  • Click Done

Add a Service Account Key​

Be prepared to store the key securely - this procedure immediately downloads the new key to your computer.

Create a key:

  • Click the 3 dots at the right of the service account we just created, and select Manage keys
  • From the Add Key menu, select Create new key
  • Chose JSON
  • Click Create to create and download the key
  • Move the key to secret/**project-name**-fastlane.json

Invite the service account to the Play Console​

  • Open the Play Console
  • Choose Users and permissions from the left menu
  • Click Invite new users
  • Use the service account email (from the JSON key file)
  • Under App permissions, select Add app
  • Select the app
  • Grant Admin (all permissions) access
  • Click Invite user

Bootstrap Fastlane in the repo​

  • Copy the fastlane files from an existing app to the app directory 
    p=pines
    mkdir -p ${p}_app/fastlane/metadata/android/en-US/changelogs
    cp noble_app/fastlane/*file ${p}_app/fastlane/
  • Edit Appfile to fix package name and json key path 
    perl -p -i -e "s/noble/${p}/g" ${p}_app/fastlane/Appfile

Test Fastlane access​

cd ${p}_app
fastlane run validate_play_store_json_key
