  • Manual test: permission flow
  • Manual test: GPS acquisition
  • Manual test: photo capture
  • Manual test: form validation
  • Manual test: webhook submission

2. ✓ LocationStatusCard shows "✗ Lokasi tidak valid"
3. ✓ Shows distance exceeded radius
4. ✓ Submit button remains DISABLED
5. ✓ User can't submit until inside radius

Expected Result: ✅ Form disabled, validation error clear

Scenario 3: Permission Denied

1. ✓ App launch → Permission dialog appears

3. ✓ Error message shown: "Gagal kirim ke server"
4. ✓ Suggest checking later or contacting admin
5. ✓ User can retry

Expected Result: ✅ Error message clear, retry available

🐛 Debug Mode Checklist

Enable Logging

android.util.Log.d("AbsensiApp", "Location: $latitude, $longitude")
android.util.Log.d("AbsensiApp", "Distance: $distance meters")
android.util.Log.d("AbsensiApp", "Validation: $isValid")
android.util.Log.d("N8nService", "Request: ${json.toString()}")
android.util.Log.d("N8nService", "Response: $responseCode")

Check Logcat

# Filter logs
adb logcat | grep "AbsensiApp"
adb logcat | grep "N8nService"

# View all logs
View → Tool Windows → Logcat (in Android Studio)

Monitor Network

  • Fiddler or Charles Proxy untuk intercept requests
