Apple SignIn:

1. Redirect Page

On Android, Apple sends connection data to an URL ("Apple Connect Redirect URL" in the settings) as POST variables, This page must redirect to the app and send all the params as GET variables.

Here is an example of this page in php:

// get the POST datas and sent it back to the app in GET variables
$post    = http_build_query($_POST);
$linkurl = "pbauth://applesignin/?$post";
header('Location: '.$linkurl);

2. AndroidManifest

Add this in the AndroidManifest.xml

Change the {REDIRECT_SCHEME} and {REDIRECT_HOST} to what is set in your redirect url. (pbauth and applesignin in the previous exemple.)

<!-- POUR LES REDIRECT APPLE SIGNIN -->
<activity android:name="com.binouze.AppleSignInActivity" android:launchMode="singleTop" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" android:exported="true">
  <!-- POUR LES REDIRECT APPLE SIGNIN -->
  <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="{REDIRECT_SCHEME}" android:host="{REDIRECT_HOST}" />
