Merhaba, bir hatayla karşılaştım. Bir süre gayet iyi çalışıyordu, o zaman ben koştuğumda sadece bir düzen düzenliyordum. Bu hataya neden oluyor ve ben gerçekten neden olmasın diye bir şeyleri geri almaya çalıştım ama yine de aynı hatayı gösteriyor. Umarım bana yardım edebilirsin. Teşekkürler !Android Studio: error: method getByCourseType sınıfında RecipeService uygulanamaz
