Sync Android env config to Gradle files with GitHub and Slack alerts

Environment Config Diff & Propagate for Android Builds

This workflow automatically detects changes in the .env.staging file in a GitHub repository and keeps Android configuration files (build.gradle and gradle.properties) in sync.It creates a new Git branch, applies updates safely, opens a pull request and notifies the team on Slack — all without manual effort.

Whenever .env.staging changes:

The workflow detects the change via GitHub webhook Compares ENV values with Android config files Automatically updates build.gradle and gradle.properties Creates a new Git branch Opens a pull request Sends a Slack notification

You get:

Automatic Android config synchronization** Safe updates via pull requests** Zero manual copying of ENV values** Instant Slack visibility for the team**

Ideal for teams managing Android app configuration across environments without mistakes.

What It Does

This workflow automates Android configuration updates end-to-end:

Listens for GitHub push events. Checks if .env.staging was modified. Stops execution if ENV file was not changed. Fetches .env.staging and gradle.properties from main. Converts both files into easy-to-compare key-value pairs. Compares ENV values against Gradle values. Creates a new Git branch for changes. Fetches files from the new branch. Identifies which variables must be updated. Applies ENV values to: build.gradle gradle.properties Commits the changes. Creates a pull request. Sends a Slack notification with PR details.

This ensures Android configs are always aligned with ENV files.

Who’s It For

This workflow is ideal for:

Android development teams DevOps & platform engineers CI/CD automation teams Teams managing multiple environments (staging / prod) Organizations avoiding manual config drift Anyone tired of copy-pasting ENV values Requirements to Use This Workflow

To run this workflow, you need:

n8n instance** (cloud or self-hosted) GitHub repository** with: .env.staging app/build.gradle gradle.properties GitHub Personal Access Token** Slack workspace** + API credentials Basic understanding of Android config files

How It Works

GitHub Webhook TriggerListens for commits pushed to the repository. ENV Change CheckWorkflow continues only if .env.staging changed. Fetch & Parse FilesReads ENV and Gradle files and converts them into key-value format. Compare Config ValuesFinds missing or mismatched variables. Create Safe BranchGenerates a timestamp-based branch from main. Apply UpdatesUpdates only the required values in: build.gradle gradle.properties Commit ChangesSaves updates to the new branch. Create Pull RequestOpens a PR for review. Notify SlackSends PR link and details to the team. Setup Steps

Import the provided n8n workflow JSON. Configure GitHub credentials in all GitHub & HTTP nodes. Set your repository name and owner. Configure Slack credentials and select a channel. Ensure .env.staging exists in your repo. Activate the workflow. Push a change to .env.staging — automation starts instantly How To Customize Nodes

Customize ENV File

Replace .env.staging with .env.production or others. Update filename in GitHub fetch + check nodes.

Customize Android Files

Extend logic to include: local.properties BuildConfig.kt settings.gradle

Customize Branch Naming

Modify the Generate New Branch Name node. Add environment names or commit IDs.

Customize Slack Message

You can add:

Emojis PR author name Changed variable list Mentions (@team, @android) Add-Ons (Optional Enhancements)

You can extend this workflow to:

Support multiple ENV files Add approval checks before PR creation Auto-merge after approval Validate ENV variable formats Send diff summary to Slack Block secrets from being committed Add Jira / Linear ticket creation Trigger Android CI build after PR creation Use Case Examples

1. Environment Sync

Keep Android configs aligned with staging ENV automatically.

2. CI/CD Safety

Prevent broken builds due to mismatched config values.

3. Team Transparency

Everyone sees config updates via Slack + PRs.

4. DevOps Automation

Remove repetitive manual config updates.

5. Audit Friendly

All changes tracked through Git history & PRs.

Troubleshooting Guide

| Issue | Possible Cause | Solution | |------------------------|----------------------------------|------------------------------------------------------| | Workflow not triggered | Webhook not configured | Re-register GitHub webhook | | No PR created | .env.staging not changed | Ensure the file is modified | | Wrong values updated | Parsing logic issue | Check KEY=VALUE format | | Slack message not sent | Invalid credentials | Reconnect Slack API | | Commit failed | Missing permissions | Check GitHub token scopes |
