Android Sensor Dashboard (Minimal)

A simple one-page Android app that shows:

• Roll / Pitch / Yaw vs time (single chart)
• Acceleration X/Y/Z vs time (single chart)
• Gyroscope X/Y/Z vs time (single chart)
• Magnetometer X/Y/Z vs time (single chart)
• Latitude / Longitude
• Pressure + altitude (derived from barometer)

GitHub Actions now does both:

• Rolling latest debug APK on push/manual trigger:
  • https://github.com/SDNT8810/android-apps/releases/tag/android-sensor-dashboard-latest
• Release APK attachment when you publish a GitHub Release tag:
  • workflow builds assembleRelease
  • generated APK is attached directly to that release

It also uploads CI artifacts:

• sensor-dashboard-debug-apk (debug builds)
• sensor-dashboard-release-apk (release builds)

• Location requires runtime permission.
• Barometer altitude uses SensorManager.getAltitude(...).
• This is intentionally minimal and single-page.
