Webview Dosya Yükleme Sorunu

merhaba ben bu kodları kullandım fakat uygulamayı çalıştırdıktan sonra dosya seçmek için tıkladığımda galeri veya kamera diye iki seçenek çıkıyor hangisini seçersem seçeyim "unfortunately has stopped" hatasını alıyorum

Sorunu çözdüm arkadaşlar, yabancı bir forumda bir arkadaş çözüm bulmuş. Destekleriniz için teşekkürler.
