Der ExoPlayer wird an der gleichen Stelle auf dem Bildschirm zum Drehen fortgesetzt

Ich verwende den ExoPlayer in meiner Aktivität. Was ich will, ist das reibungslose Abspielen von Videos im Hoch- und Querformat. Zu diesem Zweck mache ich das in onpause. Ich speichere die aktuellePlayerPosition und suche den Spieler in onresume nach dieser Position Rucken und Video wird für eine Weile angehalten und an die gespeicherte Position abgespielt.

Mein Code ist unten bitte helfen Sie mir, wie ich den Modus Portrait und Landschaft reibungslos wechseln kann. Danke
