Web servisinden db kayıtları indiren bir android uygulaması oluşturdum. Bu indirme işlemlerinin açılış ekranı görüntülenirken gerçekleştirilmesini istiyorum. Zaten bir sıçrama ekranı oluşturdum ve bunun içinde yazılı bir indirme kodu oluşturdum ama benim sorunum, indirme ekranının sonuna kadar ekranda görüntülenmiyor. Herhangi bir yardım takdir edilecektir.Ağ indirirken android açılış ekranı oluşturma
Referans için aşağıdaki açılış ekranı etkinlik sınıfını ekledim.
