This page covers the most common issues users encounter when running OpenClaw on Android/Termux and their solutions.

​
Service Issues

The most common causes are:
  1. Missing environment variables - The service needs PATH and TMPDIR set explicitly
  2. Termux wake lock not enabled - Android kills background processes without it
  3. Service daemon not running - The runit supervisor needs to be active
Solution:
# Check if service daemon is running
service-daemon status

# If not running, restart it
service-daemon stop
service-daemon start

# Enable wake lock to prevent Android from killing the process
termux-wake-lock

# Start the service
sv up openclaw

# Check status
sv status openclaw
If the service still won’t start, check the logs:
cat $PREFIX/var/log/openclaw/current
This is caused by Android’s aggressive battery optimization killing background processes.Solution:
  1. Enable wake lock (required for background operation): 
    termux-wake-lock
  2. Disable battery optimization for Termux:
    • Go to Android Settings > Apps > Termux
    • Battery > Unrestricted (or “Don’t optimize”)
  3. Keep a persistent session (optional but recommended): 
    # Run in tmux so you can reattach later
tmux new -s openclaw
sv up openclaw
# Detach with Ctrl+B then D
Wake lock must be re-enabled after device restart. Consider adding termux-wake-lock to your ~/.bashrc.
Possible causes:
  1. Service isn’t actually running
  2. Wrong port or binding address
  3. Onboarding not completed
Solution:
# 1. Verify service is running
sv status openclaw

# 2. Check if port is listening
netstat -tuln | grep 18789

# 3. Check service logs for errors
tail -f $PREFIX/var/log/openclaw/current

# 4. If onboarding wasn't completed, run:
openclaw onboard
# When asked about daemon/service installation: SELECT NO/SKIP
If the service is running but UI still won’t load:
# Restart the service
sv restart openclaw

# Wait a few seconds and try accessing again

​
Installation Errors

Error message:
EACCES: permission denied, mkdir '/tmp/openclaw'
or
Error: EACCES: permission denied, open '/some/path'
Cause: Hardcoded /tmp paths that don’t exist or aren’t writable in Termux.Solution:The setup script automatically patches this, but if you installed manually:
# 1. Set correct temp directory
export TMPDIR="$PREFIX/tmp"
export TMP="$PREFIX/tmp"
export TEMP="$PREFIX/tmp"

# 2. Create the directory
mkdir -p "$PREFIX/tmp"

# 3. Patch the hardcoded path in entry.js
sed -i "s|/tmp/openclaw|$PREFIX/tmp/openclaw|g" \
  "$PREFIX/lib/node_modules/openclaw/dist/entry.js"

# 4. Make it permanent
echo 'export TMPDIR="$PREFIX/tmp"' >> ~/.bashrc
echo 'export TMP="$PREFIX/tmp"' >> ~/.bashrc
echo 'export TEMP="$PREFIX/tmp"' >> ~/.bashrc
Error message:
gyp ERR! configure error
gyp ERR! stack Error: Can't find Python executable "python"
or
Error: Cannot find Android NDK
Cause: Node-GYP expects Android NDK environment that doesn’t exist in standard Termux.Solution:
# 1. Ensure build tools are installed
pkg install -y build-essential python cmake clang ninja

# 2. Create Node-GYP workaround (prevents NDK search)
mkdir -p ~/.gyp
echo "{'variables':{'android_ndk_path':''}}" > ~/.gyp/include.gypi

# 3. Retry installation
npm install -g openclaw@latest
If using F-Droid Termux, you may need to update to the latest version. Google Play Termux is deprecated and may have compatibility issues.
Error message:
Error: Cannot find module 'openclaw'
Error: Cannot find module '@some/dependency'
Cause: PATH not set correctly, or npm global installation failed.Solution:
# 1. Check if openclaw is actually installed
npm list -g openclaw

# 2. Verify PATH includes npm global bin
echo $PATH | grep "$PREFIX/bin"

# 3. If PATH is wrong, fix it
export PATH="$PREFIX/bin:$PATH"
echo 'export PATH="$PREFIX/bin:$PATH"' >> ~/.bashrc

# 4. Reload environment
source ~/.bashrc

# 5. If module is still missing, reinstall
npm install -g openclaw@latest --force
Symptom: Everything worked before npm install -g openclaw@latest, now service won’t start.Cause: Updates overwrite the critical /tmp/openclaw path patch in entry.js.Solution:Use the safe update script instead of direct npm install:
# Run the update script (automatically re-applies patches)
bash <(curl -s https://raw.githubusercontent.com/fingerthief/openclaw-android/refs/heads/main/update_claw.sh)
Or manually re-apply the patch:
# 1. Stop service
sv down openclaw

# 2. Update
npm install -g openclaw@latest

# 3. Re-apply patch
sed -i "s|/tmp/openclaw|$PREFIX/tmp/openclaw|g" \
  "$PREFIX/lib/node_modules/openclaw/dist/entry.js"

# 4. Restart
sv up openclaw
Always use the update script or manually re-apply patches after updating. This is required because /tmp/openclaw is hardcoded in the source.

​
Service Management

Check if service is running:
sv status openclaw
Output meanings:
  • run: openclaw: (pid 12345) 123s - Running normally
  • down: openclaw: 5s - Stopped
  • run: openclaw: (pid 12345) 1s; run: log: (pid 12346) 1s - Just started
View live logs:
tail -f $PREFIX/var/log/openclaw/current
View all logs:
cat $PREFIX/var/log/openclaw/current
Basic service commands:
sv up openclaw      # Start
sv down openclaw    # Stop
sv restart openclaw # Restart
sv status openclaw  # Check status
Error message:
sv: command not found
service-daemon: command not found
Cause: termux-services package not installed, or SVDIR not set.Solution:
# 1. Install termux-services
pkg install -y termux-services

# 2. Set SVDIR environment variable
export SVDIR="$PREFIX/var/service"
echo 'export SVDIR="$PREFIX/var/service"' >> ~/.bashrc

# 3. Reload shell
source ~/.bashrc

# 4. Start service daemon
service-daemon start

Getting Help

If you encounter an issue not covered here:
  1. Check the logs - Most errors are logged to $PREFIX/var/log/openclaw/current
  2. Review environment variables - Run env | grep -E 'TMPDIR|PATH|SVDIR'
  3. Verify installation - Run npm list -g openclaw
  4. Check service setup - Run ls -la $PREFIX/var/service/openclaw/
