E / FirebaseInstanceId：令牌检索失败：AUTHENTICATION_FAILED Firebase

Question

我尝试了许多解决方案，但是似乎都没有用。我正在尝试使用我的android项目设置firebase，但我不断收到错误消息，指出E/FirebaseInstanceId: Token retrieval failed: AUTHENTICATION_FAILED。注意：Google-services.json已安装到我的应用程序目录中。

应用程序：

dependencies {

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

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

apply plugin: 'com.google.gms.google-services'

我的应用程序：

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    classpath 'com.google.gms:google-services:4.0.1'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
