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()
);
【讨论】:
【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"
【讨论】:
【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
here
【讨论】:
【参考方案8】:implementation("com.google.firebase:firebase-iid")
【讨论】:
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。
将 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()
...
将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
