일부 기기에서는 Android 앱이 작동하지 않습니다.

Question

firebase 하위 항목을 표시하는 앱을 만들었습니다. 내 휴대 전화 (넥서스 6)에서 작동하고 다른 하나 (3 대 1)에서 작동하지만, redmi note 3과 같은 다른 기기에 앱을 설치하면 앱이 닫히고 왜 이런 일이 발생하는지 확신 할 수 없습니다.

Answer 1

때때로, 문제는 그들이 할당 된 ID와 프로젝트의 요구 엉망이 깨끗하고, 다시 심지어 어떤 경우에는 캐시 다시 시작을 무효화해야 할 십오 일에 발생한다. 이 경우에도 코드가 정상적으로 보이고 깨끗하게 다시 빌드 한 다음 Xiaomi에서 앱을 다시 실행합니다.
