Android Termux Guide

Back to Guides

This guide covers running the PicoClaw terminal binary on an ARM64 Android phone with Termux. Use the APK from picoclaw.io if you want the Android app experience; use Termux when you want a lightweight command-line install on an older or resource-constrained device.

Requirements

  • ARM64 Android device. Run uname -m in Termux and use this guide when it prints aarch64.
  • Termux installed from Termux GitHub Releases or F-Droid.
  • Network access for downloading the release and calling your LLM provider.
  • An API key for at least one configured model provider.

Install PicoClaw

Open Termux and install the packages used by the release archive and chroot wrapper:

pkg update
pkg install -y wget tar proot

Download and unpack the ARM64 Linux release:

mkdir -p ~/picoclaw
cd ~/picoclaw
wget https://github.com/sipeed/picoclaw/releases/latest/download/picoclaw_Linux_arm64.tar.gz
tar xzf picoclaw_Linux_arm64.tar.gz
chmod +x ./picoclaw

Start first-run setup through termux-chroot, which gives the Linux binary a more standard filesystem layout than a raw Android userspace:

termux-chroot ./picoclaw onboard

Configure

Edit the generated config and add at least one model provider API key:

vim ~/.picoclaw/config.json

The default workspace is ~/.picoclaw/workspace. If you want PicoClaw to read or write Android shared storage, run termux-setup-storage first and then point the workspace or any file paths at the mounted storage directory.

See Configuration Guide and Providers & Model Configuration for the available config fields and provider examples.

Run

Use one-shot agent mode to confirm the installation:

termux-chroot ./picoclaw agent -m "Hello from Termux"

For long-running use, start the gateway:

termux-chroot ./picoclaw gateway

Keep the Termux session open while PicoClaw is running. Android battery optimization can stop background work, so disable battery optimization for Termux if you expect PicoClaw to keep running after the screen locks.

Update

Your config and workspace live under ~/.picoclaw, so updating the binary does not remove them:

cd ~/picoclaw
rm -f picoclaw_Linux_arm64.tar.gz
wget https://github.com/sipeed/picoclaw/releases/latest/download/picoclaw_Linux_arm64.tar.gz
tar xzf picoclaw_Linux_arm64.tar.gz
chmod +x ./picoclaw
termux-chroot ./picoclaw version

Troubleshooting

Symptom Check
permission denied Run chmod +x ./picoclaw after unpacking the archive.
not found after running ./picoclaw Confirm uname -m prints aarch64 and that you downloaded picoclaw_Linux_arm64.tar.gz.
Files or paths behave differently than Linux Run PicoClaw through termux-chroot instead of calling the binary directly.
Provider requests fail Check the API key and network access in ~/.picoclaw/config.json.
PicoClaw stops when the phone sleeps Disable Android battery optimization for Termux and keep a foreground Termux session active.
