java.lang.SecurityException: BLUETOOTH iznine ihtiyacınız var: Ne kullanıcı 10065 ne de şu anki işlem android.permission.BLUETOOTH

Question

Android programcılığında tamamen yeniyim ve teknik olarak Android Studio'da çalışan ilk büyük projem. Arduino cihazıma Bluetooth üzerinden bağlanan ve sonunda bir .txt dosyası işleyen bir android uygulaması oluşturmaya çalışıyorum.

Şu anda Bluetooth özelliğini etkinleştiremiyorum. Kullanıcıların Bluetooth'u etkinleştirme iznini isteyen düğmeyi tıkladığımda, uygulama donuyor ve sonunda çöküyor.

Java ve logcat'i ekledim. Bu konuda herhangi bir yardım?
