인터넷에서 해결책을 찾고 있었지만 그 중 어느 것도 효과가 없었습니다. 전에이 문제가 발생 했습니까? 미리 감사드립니다!

Answer 1

확인 절차를 수행 중포 기지 클라우드 메시징을 설정, 마지막으로 나는 문제 파악 :

내가 추가했다 내 다음 줄 build.gradle 프로젝트 : maven { url "http://jcenter.bintray.com"}

그리고 지금은 그 다음과 같습니다

buildscript { 
    repositories { 
    jcenter() 
    maven { url "http://jcenter.bintray.com"} 
    } 
    dependencies { 
    classpath 'com.android.tools.build:gradle:2.2.3' 
    classpath 'com.google.gms:google-services:3.0.0' 

    // NOTE: Do not place your application dependencies here; they belong 
    // in the individual module build.gradle files 
    } 
} 
allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

Answer 2

Firebase Cloud Messaging을 올바르게 초기화하지 않았다고 생각합니다.

로 이동 : 도구> 중포 기지> 클라우드 메시징>
