Superwall -Controller -Fehler beim Kauffromgoogleplay und Speicherprodukte flattern ⇐ Android

[Anonymous]

Ich habe diesen Revenuecat Superwall -Controller von Superwall -Dokumenten zum Umgang mit Revenuecat -Einkäufen und -Theuchern und anderen Dingen in iOS und Android kopiert. In einem Projekt habe ich dies so verwendet. Kaufen Sie bei Google Play and Store PordURDUSE Ich weiß nicht, dass es alles gleich war, warum in einem anderen Projekt dieser Controller so viele Fehler hat und ich nicht weiß, wie ich diese Beacuse in früheren Projekten beheben kann.
