-#### Configuration: Using the WebView
-
-Open your app's `AndroidManifest.xml` file and add the following permissions.
-
-```xml
-<uses-permission android:name="android.permission.INTERNET" />
-<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
-```

-> The `ACCESS_NETWORK_STATE` permission it's not mandatory, but used by the WebAuthActivity to check for internet availability before executing a request.
-
-Also register the WebAuthActivity inside the `application` tag like
-
-
-```xml
-    <application android:theme="@style/AppTheme">
-
-        <!-- ... -->
-
-        <activity
-            android:name="com.auth0.android.provider.WebAuthActivity"
-            android:theme="@style/MyAppTheme"/>
-
-        <!-- ... -->
-
-    </application>
-```
-
