Overview

This module contains example of implementation Keyri with Supabase.

Contents

• Requirements
• Permissions
• Keyri Integration
• Supabase Integration
• Authentication

Requirements

• Android API level 23 or higher
• AndroidX compatibility
• Kotlin coroutines compatibility

Note: Your app does not have to be written in kotlin to integrate this SDK, but must be able to depend on kotlin functionality.

Permissions

Open your app's AndroidManifest.xml file and add the following permission:

<uses-permission android:name="android.permission.INTERNET" />

Keyri Integration

Add SDK dependency to your build.gradle file and sync project:

dependencies {
    // ...
    implementation("com.keyri:keyrisdk:$latestKeyriVersion")
    implementation("com.keyri:scanner:$latestKeyriVersion")
}

Supabase Integration

Create Supabase project and enable Email Auth. Navigate to Project Settings -> API and copy your project ApiKey. Use this key as the header for your API requests.

Use following endpoint for signup: https://pidfgjqywchqcqdjhmsj.supabase.co/auth/v1/signup

Use next endpoint for login: https://pidfgjqywchqcqdjhmsj.supabase.co/auth/v1/token?grant_type=password

Both requests must be sent with an email and password:

{
  "email": "example@mail.com",
  "password": "SecretPassword"
}

This will return authorization response (applicable for v1 API version, subject to change for other versions):

Authentication

Use refresh_token field to create payload:

val email = authResponse.user.email

val payload = JSONObject().apply {
    put("refreshToken", authResponse.refreshToken)
}.toString()

keyriAuth(email, payload)

Authenticate with Keyri. In the next showing AuthWithScannerActivity with providing publicUserId and payload.

private val easyKeyriAuthLauncher =
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
        // Process authentication result
    }

private fun keyriAuth(publicUserId: String?, payload: String) {
    val intent = Intent(this, AuthWithScannerActivity::class.java).apply {
        putExtra(AuthWithScannerActivity.APP_KEY, BuildConfig.APP_KEY)
        putExtra(AuthWithScannerActivity.PUBLIC_USER_ID, publicUserId)
        putExtra(AuthWithScannerActivity.PAYLOAD, payload)
    }

    easyKeyriAuthLauncher.launch(intent)
}
