Quick Start

This repo contains two build guides that produce similar user end states:

• Option 1: API Key
• Option 2: OAuth

The only difference in builds is that the API key build gets up and running very fast, but hard-codes your API key. The OAuth build is more suitable for production deployments because it avoids hard-coding your API key.

Scope

These quickstarts intentionally request only:

• SmartSpectraConfig.breathingMetrics
• SmartSpectraConfig.cardioMetrics
• MetricType.EXPRESSIONS

Please see the detailed documents for additional features.

Important Implementation Rules

Start by creating a new Android app project named Cool Vitals with package name com.example.coolvitals.

The Quick Start is intended so that the developer can replace app/src/main/java/com/example/coolvitals/MainActivity.kt as a full file.

• Use SmartSpectraSdk.shared.
• Use PreviewView with sdk.config.previewSurfaceProvider for native CameraX preview.
• Disable bitmap preview frames with sdk.config.imageOutputEnabled = false.
• Buffer trace samples locally before drawing charts.
• Keep camera permission in the activity flow with ActivityResultContracts.RequestPermission().

Choose Your Guide

Use Option 1: API Key for the fastest manual setup.

Use Option 2: OAuth if you need OAuth.
