[안드로이드 스튜디오] 푸시 메시지 발송 시 앱이 강제 종료되는 오류

해결 방법 (5) Retrofit과 Gson 버전 확인

build.gradle (Module: 프로젝트명.app)에서 Gson 버전을 Retrofit 버전에 맞춰줌

이제 클릭해도

최소한 튕기거나 강제 종료가 되지는 않으나

디버깅 과정에서 새로운 문제 발견

E/FirebaseMessaging: Topic sync or token retrieval failed on hard failure exceptions: java.util.concurrent.ExecutionException: java.io.IOException: SERVICE_NOT_AVAILABLE. Won't retry the operation.

---

해결 방법 (6) Cold Boot Now

기기를 재부팅하니 (5)의 에러 메시지는 사라짐

---

해결 방법 (7) AndroidManifest.xml 수정

캡처와 같이 수정

---

해결 방법 (8) Home time zone 변경

아예 컴퓨터를 재부팅하니 이런 에러가 뜸

Clock 앱에 들어가

Home time zone을 (GMT+9:00) Seoul로 설정

방법 1~8까지 시도하다보면 어느 순간 해결됨
