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.


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

dependencies {
    implementation 'link.magic:magic-android:2.1.0'
    implementation 'org.web3j:core:4.8.8-android' 

repositories {

Sync the project with new dependencies settings.


0.x has been deprecated. Please follow the new instantiation method to access the latest feature

#Creating an SDK Instance (1.x)

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.

class YourApp : Application() {

    val magic = Magic( "YOUR_PUBLISHABLE_KEY")

#Rendering Magic

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

open class MagicActivity: AppCompatActivity() {

    lateinit var magic: Magic

    override fun onCreate(savedInstanceState: Bundle?) {

        magic = (applicationContext as YourApp).magic

#Make a request

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.

val configuration = LoginWithSMSConfiguration(phoneNumber.text.toString())
val result = magic.auth.loginWithSMS(configuration)

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")
