Android App - OAuth Integration Guide

Your Authentik Configuration

Authentik URL: https://auth.dnspegasus.net
Client ID: QeSNaZPqZUz5pPClZMA2bakSsddkStiEhqbE4QZR
Redirect URI: alfredmobile://oauth/callback
Gateway URL: wss://alfred-app.dnspegasus.net

Step 1: Add Dependencies

app/build.gradle.kts:

dependencies {
    // Existing dependencies...
    
    // OAuth2 Authentication
    implementation("net.openid:appauth:0.11.1")
    
    // WebSocket (OkHttp)
    implementation("com.squareup.okhttp3:okhttp:4.12.0")
    
    // Coroutines
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.7.3")
    
    // Lifecycle
    implementation("androidx.lifecycle:lifecycle-runtime-ktx:2.7.0")
}

Step 2: Update AndroidManifest.xml

Add the OAuth callback handler:

app/src/main/AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Permissions -->
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <application
        android:name=".AlfredApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.AlfredMobile">
        
        <!-- Main Activity -->
        <activity
            android:name=".ui.MainActivity"
            android:exported="true"
            android:theme="@style/Theme.AlfredMobile">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
        <!-- OAuth Callback Activity - IMPORTANT! -->
        <activity
            android:name=".auth.OAuthCallbackActivity"
            android:exported="true"
            android:launchMode="singleTop">
            <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="alfredmobile"
                    android:host="oauth"
                    android:path="/callback" />
            </intent-filter>
        </activity>
        
    </application>

</manifest>

---

Step 3: Create Configuration Classes

app/src/main/java/com/example/alfredmobile/auth/OAuthConfig.kt:

package com.example.alfredmobile.auth

object OAuthConfig {
    const val AUTHENTIK_URL = "https://auth.dnspegasus.net"
    const val CLIENT_ID = "QeSNaZPqZUz5pPClZMA2bakSsddkStiEhqbE4QZR"
    const val REDIRECT_URI = "alfredmobile://oauth/callback"
    const val SCOPE = "openid profile email"
    
    const val AUTHORIZATION_ENDPOINT = "$AUTHENTIK_URL/application/o/authorize/"
    const val TOKEN_ENDPOINT = "$AUTHENTIK_URL/application/o/token/"
    const val USERINFO_ENDPOINT = "$AUTHENTIK_URL/application/o/userinfo/"
}

object AlfredConfig {
    const val GATEWAY_URL = "wss://alfred-app.dnspegasus.net"
}

---

Step 4: Create Auth Manager

app/src/main/java/com/example/alfredmobile/auth/AuthManager.kt:

package com.example.alfredmobile.auth

import android.app.Activity
import android.content.Context
import android.content.Intent
import android.net.Uri
import android.util.Log

import kotlin.coroutines.resumeWithException

    companion object {
        private const val TAG = "AuthManager"
        const val AUTH_REQUEST_CODE = 1001
        private const val PREFS_NAME = "alfred_auth"
        private const val KEY_ACCESS_TOKEN = "access_token"
        private const val KEY_REFRESH_TOKEN = "refresh_token"
        private const val KEY_ID_TOKEN = "id_token"
        private const val KEY_TOKEN_EXPIRY = "token_expiry"
    }
    
    private val serviceConfig = AuthorizationServiceConfiguration(
        Uri.parse(OAuthConfig.AUTHORIZATION_ENDPOINT),
        Uri.parse(OAuthConfig.TOKEN_ENDPOINT)
    )
    
    private val authService = AuthorizationService(context)
    
    /**
     * Start the OAuth login flow
     * Opens the browser for user authentication
     */
    fun startLogin(activity: Activity) {
        Log.d(TAG, "Starting OAuth login flow")

            serviceConfig,
            OAuthConfig.CLIENT_ID,
            ResponseTypeValues.CODE,
            Uri.parse(OAuthConfig.REDIRECT_URI)
        )
            .setScope(OAuthConfig.SCOPE)
            .build()
        
        val authIntent = authService.getAuthorizationRequestIntent(authRequest)
        activity.startActivityForResult(authIntent, AUTH_REQUEST_CODE)
    }
    
    /**
     * Handle the OAuth redirect response
     * Call this from your Activity's onActivityResult or callback activity
     */
    suspend fun handleAuthResponse(intent: Intent): AuthResult = suspendCancellableCoroutine { continuation ->
        val authResponse = AuthorizationResponse.fromIntent(intent)
        val authException = AuthorizationException.fromIntent(intent)

                val tokenRequest = authResponse.createTokenExchangeRequest()
                
                authService.performTokenRequest(tokenRequest) { tokenResponse, exception ->

Step 5: Create OAuth Callback Activity

app/src/main/java/com/example/alfredmobile/auth/OAuthCallbackActivity.kt:

package com.example.alfredmobile.auth

import android.content.Intent
import android.os.Bundle
import android.util.Log
import android.widget.Toast
import androidx.activity.ComponentActivity
import androidx.lifecycle.lifecycleScope
import com.example.alfredmobile.ui.MainActivity
import kotlinx.coroutines.launch

class OAuthCallbackActivity : ComponentActivity() {
    
    private lateinit var authManager: AuthManager
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        
        authManager = AuthManager(this)
        
        Log.d("OAuthCallback", "Received OAuth callback")
        
        // Handle the OAuth redirect
        lifecycleScope.launch {
            try {

    }
    
    override fun onDestroy() {
        super.onDestroy()
        authManager.dispose()
    }
}

Step 6: Create Login Screen

app/src/main/java/com/example/alfredmobile/ui/LoginScreen.kt:

package com.example.alfredmobile.ui

import android.app.Activity
import androidx.compose.foundation.layout.*
import androidx.compose.material3.*

            Text(
                text = "🤵",
                style = MaterialTheme.typography.displayLarge,
                modifier = Modifier.padding(bottom = 16.dp)
            )
            
            Text(

                color = MaterialTheme.colorScheme.onSurfaceVariant,
                modifier = Modifier.padding(bottom = 48.dp)
            )
            
            Button(

            )
        }
    }

Step 7: Update MainActivity

app/src/main/java/com/example/alfredmobile/ui/MainActivity.kt:

package com.example.alfredmobile.ui

Testing the OAuth Flow

1. Build and Install

cd ~/.openclaw/workspace/alfred-mobile
./gradlew assembleDebug
adb install app/build/outputs/apk/debug/app-debug.apk

2. Test Login Flow

1. Open the app
2. Tap "Sign in with Authentik"
3. Browser opens to Authentik login
4. Enter your credentials
5. Browser redirects back to app
6. App should show "Login successful!" and navigate to main screen

3. Check Logs

adb logcat | grep -E "AuthManager|OAuthCallback"

---

Next Steps

After OAuth is working:

1. Implement WebSocket connection (see WEBSOCKET_INTEGRATION.md)
2. Build chat UI
3. Add voice input
4. Implement lists, timers, notes

---

Troubleshooting

"No browser available"

Install a browser on your device/emulator (Chrome, Firefox, etc.)

"Invalid redirect URI"

Verify in Authentik that alfredmobile://oauth/callback is in the Redirect URIs list.

"Token exchange failed"

Check Client ID matches Authentik exactly:

QeSNaZPqZUz5pPClZMA2bakSsddkStiEhqbE4QZR

OAuth redirect doesn't return to app

Check AndroidManifest.xml has the intent-filter for alfredmobile://oauth/callback
