|
|
|
|
### Initial Setup
|
|
|
|
#### 1. Update Termux Packages
|
|
```bash
|
|
pkg update && pkg upgrade
|
|
```
|
|
|
|
#### 2. Install Required System Packages
|
|

# Install Python and development tools
|
|
pkg install python python-pip
|
|
|
|
# Install Node.js (if needed for npm packages)
|
|
pkg install nodejs
|
|
|
|
# Install which command (useful for debugging)
|
|
pkg install which
|
|
|
|

pkg install termux-api
|
|
```
|
|
|
|
### Project Setup
|
|
|
|
#### 1. Create Project Directory Structure
|
|
```bash
|
|
mkdir -p ~/projects/sms-campaign-manager
|
|
cd ~/projects/sms-campaign-manager
|
|
```
|
|
|
|
#### 2. Install Python Dependencies
|
|
```bash
|
|
pip install flask werkzeug requests
|
|
```
|
|
|
|
#### 3. Create the Flask Application
|
|
Create `app.py` with the following content:
|
|
|
|
```python
|
|
from flask import Flask, jsonify, render_template_string
|
|
import subprocess
|
|
import json
|
|
|
|
app = Flask(__name__)
|
|
|
|
@app.route('/')
|
|
def index():
|
|
return render_template_string('''
|
|
<!DOCTYPE html>

print("🚀 Starting SMS Campaign Manager on Termux...")
|
|
print("📱 Device IP: 10.0.0.193")

|
|
app.run(host='0.0.0.0', port=5000, debug=True)
|
|
```
|
|
|
|
### Running the Application
|
|
|
|
#### 1. Start the Flask Server
|
|
```bash
|
|
cd ~/projects/sms-campaign-manager
|
|
python app.py
|
|
```
|
|
|
|
#### 2. Access the Application
|
|
- **From Android device:** http://127.0.0.1:5000
|
|
- **From Ubuntu/network:** http://10.0.0.193:5000 (replace with your device IP)
|
|
- **From SSH:** Access via the device's network IP
|
|
|
|
### Features Implemented
|
|
|
|
1. **Web Interface**: Clean, responsive HTML interface
|
|
2. **Battery Status API**: Uses `termux-battery-status` to display device battery info
|
|
3. **Notification API**: Sends test notifications using `termux-notification`
|
|
4. **Network Access**: Configured to accept connections from any IP (0.0.0.0)
|
|
|
|
### Useful Commands
|
|
|
|
#### Check if server is running
|
|
```bash
|
|
ps aux | grep python
|
|
```
|
|
|
|
#### Find your device IP
|
|
```bash
|
|
ifconfig wlan0 | grep inet
|
|
# or
|
|
ip addr show wlan0
|
|
```
|
|
|
|
#### Kill existing Flask processes
|
|
```bash
|
|
pkill -f "python app.py"
|
|
```
|
|
|
|
#### Run in background with nohup
|
|
```bash
|
|
nohup python app.py > flask.log 2>&1 &
|
|
```
|
|
|
|
#### View logs
|
|
```bash
|
|
tail -f flask.log
|
|
```
|
|
|
|
### SSH Access from Ubuntu
|
|
|
|
If you want to develop from your Ubuntu machine:
|
|
|
|
```bash
|
|
# From Ubuntu, SSH into Termux
|
|
ssh android-dev
|
|
|
|
# Navigate to project
|
|
cd ~/projects/sms-campaign-manager
|
|
|
|
# Edit files with nano or vim
|
|
nano app.py
|
|
```
|
|
|
|
### Troubleshooting
|
|
|
|
#### Port Already in Use
|
|
```bash
|
|
# Find process using port 5000
|
|
lsof -i :5000
|
|
# Kill the process
|
|
kill -9 <PID>
|
|
```
|
|
|
|
#### Permission Issues with Termux API
|
|
Make sure you've granted permissions to Termux:API app in Android settings.
|
|
|
|
#### Network Access Issues
|
|
Ensure your device and Ubuntu machine are on the same network.
|
|
|
|
### Next Steps for SMS Campaign Manager
|
|
|
|
1. **Add SMS functionality**:
|
|
```python
|
|
# Send SMS using Termux API
|
|
subprocess.run(['termux-sms-send', '-n', phone_number, message])
|
|
```
|
|
|
|
2. **Add contact list management**:
|
|
```python
|
|
# Get contacts
|
|
subprocess.run(['termux-contact-list'])
|
|
```
|
|
|
|
3. **Add database support**:
|
|
```bash
|
|
pip install flask-sqlalchemy
|
|
```
|
|
|
|
4. **Add authentication**:
|
|
```bash
|
|
pip install flask-login
|
|
```
|
|
|
|
### Code-Server Alternative (Failed Attempt)
|
|
|
|
**Note:** Installing code-server on Termux proved problematic due to:
|
|
- Missing native module `argon2.node`
|
|
- Node version incompatibilities
|
|
- Architecture issues (ARM64)
|
|
|
|
**Recommendation:** Use SSH with nano/vim for editing, or use a mobile code editor app like Acode or Termux:Widget for quick edits.
|
|
|
|
### Quick Restart Script
|
|
|
|
Create `restart_server.sh`:
|
|
```bash
|
|
#!/data/data/com.termux/files/usr/bin/bash
|
|
pkill -f "python app.py"
|
|
cd ~/projects/sms-campaign-manager
|
|
python app.py
|
|
```
|
|
|
|
Make it executable:
|
|
```bash
|
|
chmod +x restart_server.sh
|
|
```
|
|
|
|
### Backup Your Work
|
|
|
|
```bash
|
|
# Create backup
|
|
tar -czf sms-campaign-backup.tar.gz ~/projects/sms-campaign-manager
|
|
|
|
# Copy to Ubuntu via SCP
|
|
scp sms-campaign-backup.tar.gz bunker-admin@10.0.0.9:~/backups/
|
|
```
