📦 Build & Installation

1. Clone the Repository

git clone https://github.com/yourusername/openchat.git
cd openchat

2. Setup API Keys

OpenChat supports multi-provider integration. You don't need to hardcode keys:

1. Open the app on your device.
2. Navigate to History (Sidebar) > API Config.
3. Add your OpenAI, Anthropic, or custom provider keys.

3. Build the APK locally

Ensure you have Android Studio Hedgehog+ and JDK 17 installed.

./gradlew assembleDebug

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

4. GitHub Actions (Auto-Build & Release)

The repository is configured with GitHub Actions to automate builds:

• Debug Builds: Every push to main generates a debug APK in the "Actions" tab.
• Release Builds: Pushing a tag (e.g., v1.0.0) triggers a signed release APK and a GitHub Release.

Setting up Signing Secrets (Required for Releases)

Add these secrets to your GitHub repository (Settings > Secrets and variables > Actions):

1. KEYSTORE_BASE64: Generate a keystore, then encode it:

   keytool -genkey -v -keystore openchat.jks -keyalg RSA -keysize 2048 -validity 10000 -alias openchat
   base64 -w 0 openchat.jks > encoded.txt
   # Copy content of encoded.txt to GitHub Secret

2. KEYSTORE_PASSWORD: The password for your keystore.
