Firebase는 SDK를 업데이트했습니다.

Firebase Android SDK에는 이제 독립적 인 버전 번호가 있으므로 더 빈번하고 유연한 업데이트가 가능합니다.

최신 버전을 사용하도록 모든 Firebase 종속성을 업데이트하십시오.

google-services플러그인 도 업데이트하십시오 :

classpath 'com.google.gms:google-services:3.3.1'

여기를 클릭하면 최신 Google 서비스를 찾을 수 있습니다

또한이 링크를 확인하여 변경 사항을 이해하고 기사에 나열된 단계를 따르십시오.

새로운 SDK 버전 발표

편집일 : 2019 년 11 월 27 일

오늘 현재 google-services플러그인 의 최신 버전 은 4.3.3입니다. 따라서 의존성은 다음과 같습니다.

classpath 'com.google.gms:google-services:4.3.3'

내 경우에는 문제가 동일합니다. 아래 단계를 수행했습니다.

1. build.gradle (gradle)

변경 :

  classpath 'com.google.gms:google-services:3.2.0'

받는 사람 :

  classpath 'com.google.gms:google-services:3.2.1'

2.build.gradle (모듈)

    implementation 'com.google.firebase:firebase-core:15.0.2'
    implementation 'com.google.firebase:firebase-messaging:15.0.2'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'

Google 위치 및 장소 :

  implementation 'com.google.android.gms:play-services-location:15.0.1'
  implementation 'com.google.android.gms:play-services-places:15.0.1'

Firebase가 라이브러리의 버전을 개별적으로 시작하기 때문에 문제가 발생합니다. 모든 것을 최신 버전으로 업데이트하면 문제가 해결됩니다.

Google Play gradle 플러그인 버전을 현재 최신 버전으로 업데이트하십시오 4.0.1.

에서 프로젝트 수준 build.gradle 파일 :

classpath 'com.google.gms:google-services:4.0.1'

최신 버전의 Google gradle plugin에 대한 정보는 다음에서 확인할 수 있습니다.

https://bintray.com/android/android-tools/com.google.gms.google-services/

그리고 앱 레벨 파일 에서 최신 버전의 개별 라이브러리를 사용 하십시오. build.gradle

implementation 'com.google.android.gms:play-services-vision:15.0.2'
implementation 'com.google.android.gms:play-services-ads:15.0.1'
implementation 'com.google.firebase:firebase-messaging:15.0.2'

다음 위치에서 최신 버전의 개별 라이브러리에 대한 정보를 얻을 수 있습니다.

https://firebase.google.com/support/release-notes/android 및 https://developers.google.com/android/guides/setup

2018 년 11 월 8 일 현재 최신 Firebase 버전에서이 문제에 직면 한 사용자는 firebase-ads최신 버전을 사용하여 나머지는 유지하면서 라이브러리를 다운 그레이드하여 충돌을 해결했습니다 .

나는 다음과 같이 바뀌었다.

googleImplementation "com.google.firebase:firebase-core:16.0.5"
googleImplementation "com.google.firebase:firebase-ads:17.0.0"  //CONFLICTING VERSION
googleImplementation "com.google.firebase:firebase-config:16.1.0"
googleImplementation "com.google.firebase:firebase-messaging:17.3.4"

에:

googleImplementation "com.google.firebase:firebase-core:16.0.5"
googleImplementation "com.google.firebase:firebase-ads:15.0.1"  //WORKING VERSION
googleImplementation "com.google.firebase:firebase-config:16.1.0"
googleImplementation "com.google.firebase:firebase-messaging:17.3.4"

또한 프로젝트 루트 build.gradle에서 다음 Google 서비스 버전을 사용하고 com.google.gms:google-services:4.2.0있습니다.

언급 된 프로그램이있는 모듈을 제외하고 종속성 트리를 분석하는 몇 가지 접근법을 시도했지만 결국 런타임에 충돌이 발생했습니다. 내가 찾은 가장 안전한 솔루션 15.0.1은firebase-ads

업데이트-2018 년 6 월 21 일

Cloud Firestore 버전 17.0.2

gRPC 요구 사항이 1.8.0에서 1.12.0으로 업데이트되었습니다. 이를 통해 Wi-Fi와 셀룰러 네트워크 간의 빠른 장애 조치가 가능합니다.

버전 16.0.1을 초대합니다

firebase-core 16.0.1과의 비 호환성을 수정했습니다.

에 새 업데이트 것처럼 위의 오류는 응용 프로그램을 다시 작성 후 오늘 출연 classpath: 'com.google.gms:google-services:3.1.0' 에

classpath: 'com.google.gms:google-services:3.2.0'

내 문제를 해결하는 데 도움이되었습니다.

또한이 게시물에 언급 된 다른 답변도 도움이 될 수 있습니다. 사용 된 google com.google.firebase 패키지 버전에 따라 Firebase 패키지를 최신 버전으로 업데이트하려고했습니다. 또한 다음 질문을 참조하여 언급 된 답변으로부터 도움을받을 수 있습니다.

또한 리포지토리 섹션의 프로젝트 gradle 파일에 다음을 추가했습니다.

maven{
url  "https://dl.bintray.com/android/android-tools"
}

빌드 gradle 및 Google 서비스의 클래스 경로를 다음과 같이 업그레이드하십시오

    classpath 'com.android.tools.build:gradle:3.1.2'
    classpath 'com.google.gms:google-services:3.3.0'

나를 위해 사용하는 것은 firebase 광고이며 SDK가 업데이트 될 때 해당 오류가 발생하기 시작했습니다. firebase 코어를 추가하여 수정했습니다.

implementation 'com.google.firebase:firebase-core:16.0.1'

1. 업데이트 google.gms버전에 최신 버전
