Reference for the Magic SDK for Android.

Overview

The Magic SDK for Android is your entry-point to secure, passwordless authentication for your mobile app. This guide will cover some important topics for getting started with Android APIs and to make the most of Magic's features.

Magic can support either server-based or serverless web applications. It is up to the developers to implement the Admin SDK to validate the DID Token.

• View the API documentation below to learn the methods you'll be using

Installation

Magic SDK is available in mavenCentral. Simply add the following line to the build.gradle in your Android project:

 Copy
dependencies {
    implementation 'link.magic:magic-android:1.0.0'
}

repositories {
    mavenCentral()
}

Sync the project with new dependencies settings.

Creating an SDK Instance (1.x)

1. Extend the application class. Instantiate Magic and assign it to application attribute. In this way, you may access the full Magic object in any activity within the application.

 Copy
class YourApp : Application() {

    val magic = Magic( "YOUR_PUBLISHABLE_KEY")
}

2. In any activity where you need Magic login, call magic.startRelayer(this) in onCreate() to enable the Magic relayer first.

 Copy
open class MagicActivity: AppCompatActivity() {

    lateinit var magic: Magic

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        magic = (applicationContext as YourApp).magic
        magic.startRelayer(this)
    }
}

Returns CompletableFuture

All Magic functions are asynchronous calls. They will return a CompletableFuture object, which resolves the results in a Response class.

To get the result without blocking the UI thread, call CompletableFuture.whenComplete to wait for the results asynchronously.

 Copy
val result = magic.auth.loginWithMagicLink("hello@example.com")

result.whenComplete { response: DIDToken?, error: Throwable? ->
    if (error != null) {
       //Handle Error
    }
    if (response != null && !response.hasError()) {
        Log.d("Magic", "You're logged in." + response.result)
    } else {
        Log.d("login", "Not Logged in")
    }
}

Destroy Relayer

To better support Android devices, we implement a way to destroy the relayer to release memory and improve the performance

 Copy
override fun onDestroy() {
    magic.destroyRelayer()
    super.onDestroy()
}

You may restart the relayer by calling

 Copy
override fun onCreate(savedInstanceState: Bundle?) {
    magic.startRelayer(this)
}
