Termux (Android) Setup

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

Prerequisites

Install Termux from GitHub or F-Droid (not Google Play, that version is deprecated)
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 --ignore-scripts @earendil-works/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

```bash
termux-open file.pdf          # Opens with default app
termux-open --chooser image.jpg      # Choose app
```

## Clipboard

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

## Notifications

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

## Device Info

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

## Sharing

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

## Other Useful Commands

```bash
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:

Termux (from GitHub or F-Droid)
Termux:API (from GitHub or F-Droid)

Then install the CLI tools:

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
