Sanal mikroskop yapmak istiyorum. 3 türde mercek ekledim butonlara ama bu ileri geri seçimlerde geri dönüşleri yapamıyor ve bir sonraki aşamalarında mikroskopta hayvan ve bitki hücrelerini incelemek isteyecek ve bunla ilgili procedurelerde de hata alıyorum. Benim amacım tek düze gitmesin mobil uygulama mesela öğrenci mercek türlerinden mikroskopta 4x ve hayvan hüresini gözlemledi ama tekrardan uygulamaya giriş çıkış yapmasın .Benim istediğim uygulamada geriye dönüş yapsın ve diğer mercekleri seçsin ve diğer hücreleri de seçebilsin. Birde bu görsellerde de lisans hatası veriyor. Bana bunla ilgili yardımcı olur musunuz
