Termux (Android) Setup

Pi runs on Android via Termux, a terminal emulator and Linux environment for Android.

Prerequisites​

  1. Install Termux from GitHub or F-Droid (not Google Play, that version is deprecated)
  2. Install Termux:API from GitHub or F-Droid for clipboard and other device integrations

Installation​

# Update packages
pkg update && pkg upgrade

# Install dependencies
pkg install nodejs termux-api git

# Install pi
npm install -g @mariozechner/pi-coding-agent

# Create config directory
mkdir -p ~/.pi/agent

# Run pi
pi

Clipboard Support​

Clipboard operations use termux-clipboard-set and termux-clipboard-get when running in Termux. The Termux:API app must be installed for these to work.

Image clipboard is not supported on Termux (the ctrl+v image paste feature will not work).

Example AGENTS.md for Termux​

Create ~/.pi/agent/AGENTS.md to help the agent understand the Termux environment:

# Agent Environment: Termux on Android

## Location
- **OS**: Android (Termux terminal emulator)
- **Home**: `/data/data/com.termux/files/home`
- **Prefix**: `/data/data/com.termux/files/usr`
- **Shared storage**: `/storage/emulated/0` (Downloads, Documents, etc.)

## Opening URLs
```bash
termux-open-url "https://example.com"

Opening Files​

termux-open file.pdf          # Opens with default app
termux-open -c image.jpg      # Choose app

Clipboard​

termux-clipboard-set "text"   # Copy
termux-clipboard-get          # Paste

Notifications​

termux-notification -t "Title" -c "Content"

Device Info​

termux-battery-status         # Battery info
termux-wifi-connectioninfo    # WiFi info
termux-telephony-deviceinfo   # Device info

Sharing​

termux-share -a send file.txt # Share file

Other Useful Commands​

termux-toast "message"        # Quick toast popup
termux-vibrate                # Vibrate device
termux-tts-speak "hello"      # Text to speech
termux-camera-photo out.jpg   # Take photo

Notes​

  • Termux:API app must be installed for termux-* commands
  • Use pkg install termux-api for the command-line tools
  • Storage permission needed for /storage/emulated/0 access

## Limitations

- **No image clipboard**: Termux clipboard API only supports text
- **No native binaries**: Some optional native dependencies (like the clipboard module) are unavailable on Android ARM64 and are skipped during installation
- **Storage access**: To access files in `/storage/emulated/0` (Downloads, etc.), run `termux-setup-storage` once to grant permissions

## Troubleshooting

### Clipboard not working

Ensure both apps are installed:
1. Termux (from GitHub or F-Droid)
2. Termux:API (from GitHub or F-Droid)

Then install the CLI tools:
```bash
pkg install termux-api

Permission denied for shared storage​

Run once to grant storage permissions:

termux-setup-storage

Node.js installation issues​

If npm fails, try clearing the cache:

npm cache clean --force
