Magic OAuth for Android

#Installation

Social Logins work as an extension to Magic SDK. To add Social Login to your Magic integration, follow these steps to install the OAuth Extension:

In the build.gradle, add following lines.

dependencies {

    implementation 'link.magic:magic-android:2.1.0'

    implementation 'org.web3j:core:4.8.8-android'

    implementation 'link.magic:magic-ext-oauth:1.0.0'

Build your project
Add the following activities and intent filter for Chrome Custom Tabs inside your application element. You may configure the scheme and the host for the oauth redirection

<!-- OAuth Activity -->

        <activity android:name="link.magic.android.extension.oauth.customTab.CustomTabMainActivity"

            android:configChanges=

                "keyboard|keyboardHidden|screenLayout|screenSize|orientation"

            android:label="@string/app_name" />

        <activity

            android:name="link.magic.android.extension.oauth.customTab.CustomTabActivity"

            android:exported="true">

            <intent-filter>

                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />

                <category android:name="android.intent.category.BROWSABLE" />

                <data android:scheme="link.magic.demo" android:host="callback"/>

            </intent-filter>

        </activity>

Invoke OAuth 2.0 flow, the redirection link shall match the one you registered in the AndroidManifest.xml

fun loginWithOAuth(view: View) {

        val configuration = OAuthConfiguration(OAuthProvider.GITHUB, "link.magic.demo://callback")

        magic.oauth.loginWithPopup(configuration)

In onActivityResult method, pass the data intent to magic.oauth.getResult method to get the authentication result .

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

        val result = magic.oauth.getResult(data)

        result.whenComplete { response: OAuthResponse?, error: Throwable? ->

            if (error != null) {

                Log.d("error", error.localizedMessage)

            if (response != null && !response.hasError()) {

                response.result.magic.idToken?.let { Log.d("login", it) }

                startLoggedInActivity()

            } else {

                Log.d("login", "Not Logged in")

        super.onActivityResult(requestCode, resultCode, data)
