Harita görünümüne V2 gösterilemiyor

Question

Gelişmekte olduğum uygulamanın içinde bir harita görüntüsü alıyorum. Google konsolunda bir API anahtarını başarıyla oluşturdum ve izne izin ekledim ve bazı hatalar için logcat'i kontrol et ama hiçbir şey yok.

    // Updates the location and zoom of the MapView
