Question

当我向我的班级初始化Fire base身份验证时，应用程序停止也许在问题中有问题，但每件事物都有一个托盘

这是我的代码

class Test : AppCompatActivity() {

lateinit var mAuth: FirebaseAuth

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_test)

    mAuth = FirebaseAuth.getInstance()

}
}

这是我的礼物

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:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:28.0.0'
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-auth:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-storage:16.0.1'
implementation 'com.google.firebase:firebase-config:16.0.0'
implementation 'com.google.android.gms:play-services-auth:16.0.0'

}

您正在使用旧版本的Firebase依赖项，并且缺少Google服务插件。要解决此问题，请使用以下依赖项：

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:design:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:28.0.0'
    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-auth:16.1.0'
    implementation 'com.google.firebase:firebase-database:16.0.6'
    implementation 'com.google.firebase:firebase-storage:16.0.5'
    implementation 'com.google.firebase:firebase-config:16.1.3'
    implementation 'com.google.android.gms:play-services-auth:16.0.1'
}
apply plugin: 'com.google.gms.google-services'

还请添加以下强制性的依赖项：

implementation 'com.google.firebase:firebase-core:16.0.6'

您的应用gradle文件现在必须明确列出com.google.firebase:firebase-core作为Firebase服务按预期工作的依赖项。

在顶级build.gradle文件中，请确保具有最新版本的Google服务插件：

classpath 'com.google.gms:google-services:4.2.0'
