Sample Activities

This section provides detailed documentation for the sample activities included in the MultiSet Android SDK. These activities demonstrate how to implement VPS localization and object tracking in your Android application.

Available Activities

MainActivity

The entry point for the SDK demo application. Handles SDK initialization, authentication, and navigation to both the AR localization and object tracking activities. Displays a card-based UI with a Localization card (mode picker + Start button) and an Object Tracking card.

MultiSetLocalizationActivity

Unified AR localization activity that supports both single-frame and multi-frame localization modes. The mode is selected at launch time via an intent extra.

ObjectTrackingActivity

Dedicated AR activity for detecting and tracking pre-registered physical objects. Once an object is tracked, its 3D mesh is fetched from the MultiSet platform and rendered in the AR scene with an animated glowing outline shader.

Localization Mode Comparison

Feature	Single-Frame	Multi-Frame
Frames captured	1	4–6 (configurable)
Accuracy	Good	Better
Capture time	Instant	~2–3 seconds
Network usage	Lower	Higher
Best for	Quick localization	Precise positioning

Object Tracking at a Glance

Feature	Description
Supported objects	Up to 10 simultaneously
Mesh rendering	GLB fetched from platform, outline-only animated shader
Auto-tracking	Starts automatically on session ready
Background tracking	Periodic re-tracking after first success
Confidence filtering	Rejects low-confidence results automatically

Getting Started

1. Initialize the SDK and authenticate in MainActivity

2. For localization: configure LocalizationConfig, then launch MultiSetLocalizationActivity

3. For object tracking: configure ObjectTrackingConfig, then launch ObjectTrackingActivity

See LocalizationConfig and ObjectTrackingConfig for full configuration options.
