Lcom/google/firebase/FirebaseApp 类中没有虚拟方法 setTokenProvider(Lcom/google/firebase/internal/InternalTokenProvider;)V

Question

我是新来的。

在我的 Android 应用中，编译应用时出错。我正在使用 Firebase 身份验证和 Firebase 实时数据库。我按照 Firebase 官方网站上的手册进行操作。但是为什么我会收到这个错误。试了几天还是不行。

提前感谢帮助。

错误：

E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.login_firebase, PID: 7570

这些是我添加到 Android Studio 中的代码。

Bulid.gradle

dependencies {
    classpath 'com.android.tools.build:gradle:3.6.1'
    classpath 'com.google.gms:google-services:4.2.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

Bulid.gradle(app)

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

  android {
      compileSdkVersion 29
      buildToolsVersion "29.0.3"

defaultConfig {
    applicationId "com.example.login_firebase"
    minSdkVersion 21
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
       }
   }

  }

  dependencies {
      implementation fileTree(dir: 'libs', include: ['*.jar'])

您的 Firebase SDK 版本完全不匹配。设置它们，使其与您在documentation 中看到的最新版本相匹配。您应该随着时间的推移更新它们，以便它们保持最新。您还应该删除 firebase-core，因为它不再需要。

      implementation 'com.google.firebase:firebase-auth:19.4.0'
      implementation 'com.google.firebase:firebase-database:19.4.0'
      implementation 'com.google.firebase:firebase-analytics:17.5.0'
