Building and Releasing

This project uses Gradle.

Local Development

To build the application, run:

./gradlew assembleDebug

The APK will be located at app/build/outputs/apk/debug/app-debug.apk.

Make sure to install JDK 17.

API Keys

All API keys are handled in-app via the Settings screen — no secrets are hardcoded in the codebase.

GitHub Actions (APK Signing & Release)

GitHub Actions are configured to automatically build and sign releases.

1. GitHub Secrets: Add these secrets to your repository:

   • KEYSTORE_BASE64: Your keystore binary as a base64 string. Generate with: keytool -genkey -v -keystore openchat.jks -keyalg RSA -keysize 2048 -validity 10000 -alias openchat Then encode: base64 -w 0 openchat.jks
   • KEYSTORE_PASSWORD: Your keystore password.
   • KEY_ALIAS: openchat
   • KEY_PASSWORD: Your key password.

2. Trigger a Release: Push a Git tag starting with v:

   git tag v1.0.0
   git push --tags

   The pipeline will build the signed APK and create a GitHub Release automatically.

3. Installation: Download the APK from the latest GitHub Release and install on your device (ensure "Install from Unknown Sources" is enabled).
