updateDisplay 메서드를 사용하여 응용 프로그램이 충돌을 일으킬 때까지 모든 것이 작동합니다.

Question

메서드를 코드로 채워서 setText/get을 사용하여 textViews을 업데이트하면 모든 것이 화면에 올바르게 나타납니다.

DarkSky API에서 업데이트하기 위해 setText/get 코드를 입력하기 전에 앱이 충돌하지 않지만 일단 입력되면 앱이 다운되고 다시 시도하라는 메시지가 표시됩니다.

모든 것이 올바르게 입력되었지만 어떤 이유로 앱이 정보를 가져 가지 않을 것이라고 생각합니다. 또한, 최근 버전의 OkHTTP를 요람에 사용하고 있으므로이 문제는 거기에 있지 않습니다. (사용 권한도 사용됩니다)
