我尝试了很多解决方案,但没有任何帮助。

【问题讨论】:

使用相同版本的播放服务库。也不要在依赖项中使用 + 运算符。找到版本services-base:15.+'vision:12.0.1 @alex-khanenya 你找到解决方案了吗?我有同样的错误。谢谢 【参考方案1】:

面临同样的问题。然后我发现我错过了将 Firebase 与 Android 项目集成的一组重要说明:https://firebase.google.com/docs/android/setup#add_firebase_to_your_app

以下是该文档中对我的案例有所帮助的步骤摘要:

    生成google-services.json 并将其放入您的android/app/ 目录。 将classpath 'com.google.gms:google-services:4.1.0' 添加到您的根级build.gradle 配置的buildscript -> dependencies 部分;将google() 添加到同一文件的allprogects -> repositories 部分。 将implementation 'com.google.firebase:firebase-core:16.0.3' 添加到应用模块build.gradle 文件的dependencies 部分;在同一文件的最底部添加apply plugin: 'com.google.gms.google-services'。 同步和重建。现在它应该可以工作了。

【讨论】:

@alex-khanenya 如果解决了问题,请考虑将答案标记为已接受。【参考方案2】:

在您的 android/app/build.gradle 上添加一个依赖项的更多实现:

...
dependencies 
    implementation "com.google.firebase:firebase-auth:17.0.0"
    ...

【讨论】:

【参考方案3】:

所涉及的依赖项可能存在一些问题。

就我而言,在应用级别 build.gradle 中进行以下更改非常有效

dependencies
     implementation 'com.google.firebase:firebase-auth:17.0.0'
     implementation 'com.firebaseui:firebase-ui-database:6.0.2'
     ...

【讨论】:

【参考方案4】:

更改了最新的 firebase-messaging google 依赖项,并在应用程序 gradle 文件的同一版本中修改了其他依赖项。现在工作正常

dependencies version detail you can refer here

dependencies 
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
    implementation 'com.google.firebase:firebase-auth:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:18.0.0'

【讨论】:

【参考方案5】:

在我的例子中,我忘记在 MainApplication.java 中注释数据库包

    @Override
    protected List<ReactPackage> getPackages() 
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
            new AsyncStoragePackage(),
            new RNCameraPackage(),
            new VectorIconsPackage(),
            new RNGestureHandlerPackage(),
        new RNFirebasePackage(),
        // add/remove these packages as appropriate
        //new RNFirebaseAdMobPackage(),
        new RNFirebaseAnalyticsPackage(),
        //new RNFirebaseAuthPackage(),
        // new RNFirebaseRemoteConfigPackage(),
        new RNFirebaseCrashlyticsPackage(),
        // new RNFirebaseDatabasePackage(), <==== Comment this package
       // new RNFirebaseFirestorePackage(),
        // new RNFirebaseFunctionsPackage(),
        new RNFirebaseInstanceIdPackage(),
       // new RNFirebaseInvitesPackage(),
        new RNFirebaseLinksPackage(),
        new RNFirebaseMessagingPackage(),
        new RNFirebaseNotificationsPackage(),
        new RNFirebasePerformancePackage()
       // new RNFirebaseStoragePackage()
      );

【参考方案6】:

如果您在 Flutter 中遇到此问题,请在您的 android/app/build.gradle 中添加此依赖项。并运行你的 main.dart。无需在 ListView 中添加任何类型的控制器。如果您在该页面上使用列表视图。如果您使用的是 Firebase,请在依赖项中添加此内容。

implementation "com.google.firebase:firebase-auth:19.3.0"

【参考方案7】:

我也遇到过同样的问题。您必须更改 pakage.json 文件中的 react-native-firebase 版本。我从这里找到了解决方案

【讨论】:

【参考方案8】:
implementation("com.google.firebase:firebase-iid")

这并没有提供问题的答案。一旦你有足够的reputation,你就可以comment on any post;相反,provide answers that don't require clarification from the asker。 - From Review 虽然此代码可能会回答问题,但提供有关它如何和/或为什么解决问题的额外上下文将提高​​答案的长期价值。您可以在帮助中心找到更多关于如何写好答案的信息:***.com/help/how-to-answer。祝你好运?【参考方案9】:

解决方案 1:

在您的 android/app/build.gradle 文件中再添加一个依赖项实现。

dependencies 
    implementation "com.google.firebase:firebase-auth:17.0.0"
    ...

解决方案 2:

生成google-services.json 并将其放入您的android/app/ 目录。

classpath 'com.google.gms:google-services:4.1.0' 添加到 buildscript -> 根级 build.gradle 配置的依赖项部分,并将 google() 作为第一个条目添加到 allprogects -> 同一文件的存储库部分。

  buildscript 
      repositories 
          google()
          jcenter()
      
      dependencies 
          ...
          classpath 'com.google.gms:google-services:4.1.0'
      
  
  allprojects 
      repositories 
          google()
          ...
      
  

implementation 'com.google.firebase:firebase-core:16.0.3' 添加到应用模块的build.gradle 文件的依赖项部分,并在同一文件的最底部添加apply plugin: 'com.google.gms.google-services'

dependencies 
    ...
    implementation 'com.google.firebase:firebase-core:16.0.3'
 
apply plugin: 'com.google.gms.google-services'

同步和重建。

【讨论】:

【参考方案10】:

更新您的 Firebase 库!!!!

例如。如果您的应用使用 Firebase 身份验证,请在 Google 为它提供最新版本的文档中,将其粘贴到您的 build.gradle

您的 Firebase 助手在 Android Studio 中添加的库通常较旧。

【讨论】:

【参考方案11】:

在 gradle.properties 文件中,尝试添加::

android.enableJetifier = true
android.useAndroidX = true
