무선으로 앱설치

아래와 같이 스튜디오에 뜨고
앱에 오류 발생이라고 휴대폰 화면에 뜹니다.
"앱에 버그가 있어 앱을 종료했습니다 개발자가 오류 수정본을 제공하면 앱을 업데이트해보세요" 라구요
유선연결 하는 링크를 알려주시면 참고 하겠습니다.

usb선을 연결하는 방법입니다.

실행해 보았으나 동일한 증상이네요.. 흐름을 탓을 때 들어야하는데요..

로그는 잘 빌드가 되었다고 하는데, 뭔가 에러나는 포인트에서 나오는 로그를 보내주시겠어요?

https://www.inflearn.com/questions/668037

혹시 위와 같은 동일한 에러이면 이 부분을 참고해보시겠어요?

오후 10:23 Executing tasks: [:app:assembleDebug] in project C:\Users\john\AndroidStudioProjects\fb_log_in_test

오후 10:23 Gradle build finished in 1 s 737 ms

오후 10:23 Launch succeeded

로그는 정상적으로 나오는것 같습니다. 주신 링크도 참고햇는데 동일한 증상이네요..

에뮬레이터도 마찬가지인가요?

애뮬레이터로 하기가 어려워서 무선으로 했습니다.. 컴퓨터도 받쳐주질 못하는 것 같아서요

log cat에서 다음과 같이 빨간불로 들어오네요

이것도 있네요..

우선 에뮬레이터문제인지 / 코드 문제인지 알아야할 것 같습니다.

에뮬레이터로 정상 동작하는지 확인 후, 원인을 찾기 어려우시면 코드를 깃허브에 공유하고 링크를 공유주시겠어요?
