name: termux-device description: Android device control via Termux API — battery, brightness, torch, vibrate, volume, audio info, sensors, fingerprint, location, WiFi, clipboard, notifications, dialogs, toasts, wake lock, wallpaper, downloads

Termux Device — Android Hardware, Sensors & UI

Control device hardware, sensors, and system UI from the command line via Termux API.

Important: Permission Handling

When a Termux API command runs for the first time, Android may prompt the user to grant permission. The command will fail with a permission/access error, but the user sees an approval dialog on their device. Always retry the command once if you get a permission error — the user will have approved the permission by then, and the retry will succeed.

Do not assume you lack access after a single permission failure. One retry is all it takes.

Common Patterns

Battery check before long tasks

BATTERY=$(termux-battery-status)
LEVEL=$(echo "$BATTERY" | jq -r '.percentage')
STATUS=$(echo "$BATTERY" | jq -r '.status')

if [ "$LEVEL" -lt 20 ] && [ "$STATUS" = "DISCHARGING" ]; then
  termux-toast "Battery low ($LEVEL%). Plug in before running."
else
  echo "Battery OK: ${LEVEL}% (${STATUS})"
fi

Notification with progress updates

termux-notification --id build -t "Build" -c "Starting..." --ongoing
# ... run build ...
termux-notification --id build -t "Build" -c "Tests passed" --alert-once
# ... deploy ...
termux-notification-remove build
termux-toast "Build complete!"

Get user confirmation via dialog

RESULT=$(termux-dialog confirm -t "Deploy to production?")
if echo "$RESULT" | jq -e '.text == "yes"' > /dev/null 2>&1; then
  echo "Deploying..."
else
  echo "Cancelled."
fi

Location-stamped log

LOC=$(termux-location -p network)
LAT=$(echo "$LOC" | jq -r '.latitude')
LON=$(echo "$LOC" | jq -r '.longitude')
echo "[$(date -Iseconds)] lat=$LAT lon=$LON" >> /sdcard/ruuh/location.log

Full notification lifecycle

# Post a notification
termux-notification --id build -t "Build" -c "Compiling..." --ongoing

# Check it's active
termux-notification-list | jq '.[] | select(.tag == "build")'

# Update it
termux-notification --id build -t "Build" -c "Running tests..." --alert-once

# Remove when done
termux-notification-remove build
termux-toast "Build complete!"

Keep device awake during a task

termux-wake-lock
# ... long running process ...
termux-wake-unlock
termux-vibrate -d 200
termux-toast "Task finished"
