Quick Start

Complete your first mDL verification in under 10 minutes.

Step 1: Initialize the SDK

Initialize the SDK early in your application lifecycle, typically in your Application class or main Activity. You'll need your API key from the Owl Eyes Dashboard.

Tip: For production apps, initialize the SDK in your Application class so it's ready before any Activity needs it.

Step 2: Create a Verification Session

Create a session specifying the verification channel and what claims (data) you want to request. For this example, we'll use QR code verification to check if someone is over 21.

Step 3: Process Device Engagement

When the holder scans your QR code with their wallet app, they'll present a response. Process this response to complete the verification:

Complete Example

Here's a complete Activity that implements QR-based age verification:

Environments

The SDK supports multiple environments for different stages of development:

Environment	Use Case
`MDLEnvironment.PRODUCTION`	Live production traffic with real credentials
`MDLEnvironment.SANDBOX`	Testing with test credentials (no real verification)
`MDLEnvironment.DEVELOPMENT`	Local development with emulator

Next Steps

Now that you've completed your first verification, explore these topics:

Verification Channels – Learn about NFC and Bluetooth LE options
Claim Sets – Request identity data, photos, and driving privileges
Session Management – Handle session lifecycle and timeouts
Error Handling – Handle errors gracefully
