# Termux Comms — SMS, Contacts, Camera, Audio & Media

Access Android communication and media features 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

### Read and reply to latest SMS

```bash
MSG=$(termux-sms-list -l 1 | jq -r '.[0]')
SENDER=$(echo "$MSG" | jq -r '.number')
BODY=$(echo "$MSG" | jq -r '.body')
echo "From: $SENDER"
echo "Message: $BODY"

# Reply
termux-sms-send -n "$SENDER" "Got it, thanks!"
```

### Take a photo and share it

```bash
termux-camera-photo /sdcard/ruuh/snap.jpg
termux-media-scan /sdcard/ruuh/snap.jpg
termux-share /sdcard/ruuh/snap.jpg
```

### Voice notification for task completion

```bash
# Run at the end of a long process
termux-tts-speak "Your build has finished successfully"
termux-vibrate -d 300
```

### Record a voice memo

```bash
termux-toast "Recording... speak now"
termux-microphone-record -f /sdcard/ruuh/memo.m4a -l 60
# Recording runs in background for up to 60 seconds
# Stop early with:
termux-microphone-record -q
termux-toast "Recording saved"
```

### Find a contact and send SMS

```bash
# Search contacts for "Alice"
CONTACT=$(termux-contact-list | jq -r '.[] | select(.name | test("Alice"; "i"))')
NUMBER=$(echo "$CONTACT" | jq -r '.number')

if [ -n "$NUMBER" ]; then
  termux-sms-send -n "$NUMBER" "Hey Alice!"
  termux-toast "SMS sent to $NUMBER"
else
  termux-toast "Contact not found"
fi
```

### Voice-commanded SMS

```bash
# Speak to send a text message
termux-tts-speak "Who should I text?"
NAME=$(termux-speech-to-text)
CONTACT=$(termux-contact-list | jq -r --arg n "$NAME" '.[] | select(.name | test($n; "i"))')
NUMBER=$(echo "$CONTACT" | jq -r '.number')

if [ -z "$NUMBER" ]; then
  termux-tts-speak "Contact not found"
  exit 1
fi

termux-tts-speak "What should I say?"
MESSAGE=$(termux-speech-to-text)
termux-sms-send -n "$NUMBER" "$MESSAGE"
termux-tts-speak "Message sent"
```

### Audio alert with fallback

```bash
# Try to play a sound file, fall back to TTS
if [ -f /sdcard/ruuh/alert.mp3 ]; then
  termux-media-player play /sdcard/ruuh/alert.mp3
else
  termux-tts-speak "Alert: task requires your attention"
fi
termux-vibrate -d 500
```
