    java.lang.IllegalArgumentException: xxxxxxxxxxxxxxxxxxxxxxxxxxxxx: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
    Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

修正内容

gradle修正

-implementation 'com.google.firebase:firebase-messaging'
+implementation 'com.google.firebase:firebase-messaging:23.0.0'

Token取得修正

FirebaseInstanceIdが使えなくなったので、FirebaseMessagingへ変更

-	FirebaseInstanceId.getInstance().getInstanceId().addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
+	FirebaseMessaging.getInstance().getToken().addOnCompleteListener(new OnCompleteListener<String>() {

-		String token = task.getResult().getToken();
+		String token = task.getResult();

通知タップのPendingIntentのところ修正

インテントの安全でない起動
Android 12 以降では、プラットフォームのセキュリティを強化するため、インテントの安全でない起動を検出するデバッグ機能が導入されました。このような安全でない起動がシステム> によって検出されると、StrictMode 違反が発生します。

ということなので、FLAGを変更。

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
-				PendingIntent.FLAG_ONE_SHOT);
+				PendingIntent.FLAG_IMMUTABLE);
