## 🚀 Quick Start

### One-Command Deployment
```bash
# 1. Deploy to Android with correct directory structure
# Scripts go to ~/bin/
scp -P 8022 android/*.sh android-dev@10.0.0.193:~/bin/
ssh android-dev "chmod +x ~/bin/*.sh"

# Python apps go to ~/projects/sms-campaign-manager/
ssh android-dev "mkdir -p ~/projects/sms-campaign-manager"
scp -P 8022 android/*.py android-dev@10.0.0.193:~/projects/sms-campaign-manager/

# Start all services
ssh android-dev "~/bin/start-all-services.sh"

# 2. Start Ubuntu homelab
./run.sh start
# OR with docker-compose
docker-compose up -d

# 3. Verify everything is running
curl http://10.0.0.193:5001/health    # Android SMS API
curl http://10.0.0.193:5000/          # Android Monitor  
curl http://localhost:5000/           # Ubuntu Dashboard
```

### Prerequisites
- Docker & Docker Compose installed
- Android device with USB debugging enabled
- Local network access to Android device

### 1. Clone and Configure
```bash
# Clone or navigate to project directory
cd "ABD Texting Testing"

# Copy environment template
cp config/.env.example .env

# Edit configuration for your Android device
nano .env
```

### 2. Launch with Docker Compose
```bash
# Quick start using convenience script
./run.sh start

# Or manually with docker-compose
docker-compose up -d

# View logs
docker-compose logs -f

# Access web interface
open http://localhost:5000
```

### 3. Connect Your Android Device
The system will automatically discover and connect to your Android device using the IP configured in `.env`.

### 4. Deploy Android Services
Copy the pre-configured service files to their correct directories on Termux:

```bash
# Deploy shell scripts to ~/bin/ directory
scp -P 8022 android/*.sh android-dev@10.0.0.193:~/bin/
ssh -p 8022 android-dev@10.0.0.193 "chmod +x ~/bin/*.sh"

# Deploy Python applications to ~/projects/sms-campaign-manager/
ssh -p 8022 android-dev@10.0.0.193 "mkdir -p ~/projects/sms-campaign-manager"
scp -P 8022 android/app.py android/termux-sms-api-server.py android-dev@10.0.0.193:~/projects/sms-campaign-manager/

# Verify deployment
ssh android-dev "ls -la ~/bin/*.sh && ls -la ~/projects/sms-campaign-manager/*.py"
```

### 5. Start Android Services
Your S24 Ultra runs two services for SMS operations. Use the automated startup script:

```bash
# Start all services at once (recommended)
ssh android-dev "~/bin/start-all-services.sh"

# Or start services individually:
ssh android-dev "~/bin/sms-service.sh start"        # SMS API Server
ssh android-dev "~/bin/start-monitoring.sh"         # Monitoring Interface

# Check service status
ssh android-dev "~/bin/sms-service.sh status"
curl http://10.0.0.193:5001/health                  # SMS API health check
curl http://10.0.0.193:5000/                        # Monitoring dashboard
```

**Available Service Scripts:**
- `start-all-services.sh` - Start both services with health checks
- `sms-service.sh` - Service management (start/stop/status)
- `start-sms-api.sh` - SMS API Server only
- `start-monitoring.sh` - Monitoring interface only
- `network-monitor.sh` - Network connectivity monitoring

**Service URLs:**
- 🚀 **SMS API Server**: http://10.0.0.193:5001 (REST API for sending SMS)
- 📊 **Monitoring Interface**: http://10.0.0.193:5000 (Web dashboard for testing)

### 5. Verify Full System
```bash
# Test Ubuntu homelab → Android connection
curl http://localhost:5000/api/phone/status

# Test Android SMS API
curl http://10.0.0.193:5001/health

# Access web interfaces
open http://localhost:5000          # Main campaign manager
open http://10.0.0.193:5000         # Android monitoring dashboard
```

---

## 📱 Android Setup

### Method 1: ADB Wireless (Recommended)
1. Enable Developer Options on Android
2. Enable USB Debugging
3. Enable Wireless Debugging
4. Connect to same WiFi network as your homelab
5. Run `./auto.sh` to auto-discover and connect

### Method 2: Termux API Integration
1. Install Termux and Termux:API from F-Droid
2. Grant SMS permissions to Termux:API
3. Run `./setup-termux-integration.sh` from your homelab
4. API server will run on port 5001

---

## 🎯 Usage Examples

### Campaign Management
1. **Access Web Interface**: `http://localhost:5000`
2. **Upload Contacts**: CSV with `phone`, `name`, `message` columns
3. **Create Campaign**: Set message template with `{name}` variables
4. **Monitor Progress**: Real-time dashboard with analytics

### CSV Format
```csv
phone,name,message
7802921731,Reed,Hi {name}! Your custom message here
7809101334,Ken,Hello {name}, different message per contact
```

### Template Variables
- `{name}` - Contact name from CSV
- `{phone}` - Contact phone number  
- Custom fields from your CSV columns

---

## 🧪 Testing & Troubleshooting

### Health Checks
```bash
# Check Docker containers
docker-compose ps

# Test phone connectivity  
curl http://localhost:5000/api/phone/status

# View application logs
docker-compose logs sms-campaign

# Test SMS functionality
curl -X POST http://localhost:5000/api/sms/test \
  -H "Content-Type: application/json" \
  -d '{"phone":"YOUR_NUMBER","message":"Test message"}'
```

### Common Issues
- **Phone not connecting**: Check IP address in `.env` and WiFi connectivity
- **SMS not sending**: Verify ADB connection and screen coordinates
- **Permission denied**: Ensure Docker has USB device access
- **Database errors**: Check volume mounts and file permissions
